United States of America OCCUPATIONAL SAFETY AND HEALTH REVIEW COMMISSION 1120 20th Street, N.W., Ninth Floor Washington, DC 20036-3457 SECRETARY OF LABOR, Complainant, v. OSHRC Docket No.10-1372 BRIONES UTILITY COMPANY, Respondent. ON BRIEFS: Allison Graham Kramer, Attorney;HeatherR.Phillips, Counsel for Appellate Litigation; Joseph M. Woodward, Associate Solicitor of Labor forOccupational Safety andHealth; M. Patricia Smith, Solicitor of Labor; U.S. Department of Labor, Washington, DC For the Complainant Edward L. Pina, Esq.;Edward L. Pina & Associates, PC,San Antonio, TX For the Respondent DECISION Before: ATTWOOD, Chairman;andMacDOUGALL,Commissioner. BY THE COMMISSION: The Occupational Safety and Health Administration issued BrionesUtility Companya serious citation alleging a violation of 29 C.F.R. § 1926.652(a)(1) for failing to protect employees working in a trench from potential cave-ins. Administrative Law Judge John H. Schumacher vacated the citation, finding that the Secretary failed to establishemployeeexposure. For the following reasons, we reverse the judge and affirm the citation. BACKGROUND Brionesis an excavation contractor thatwasexposingundergroundsewer and gas linesat a worksite in San Antonio, Texas. An OSHA compliance officerdrove pasttheworksiteand stopped to inspect whenhesaw an open trench. The COphotographed a Briones employeeworking in a trench that was 10 feet long, 3 feet wide,and 7 feet deep, with aluminum hydraulicshoring installed at one end. Asecond,uninstalled shorewas alsoat theworksite. The shoringinstalledin the trenchincludedtwo hydraulic cylinders(one above the other)thatspanned the width of the trench and pressed against vertical rails on either side. Sandwiched between the railsand trench walls were4-foot-wide,8-foot-tallpanels.Measured from the center line of the hydraulic cylinders, the distance to thecloserend of the trench was 2 feet, and the distance to the fartherend was8 feet. One of the CO’sphotographs showstheemployeewho wasstandingin the trench, bent over, with the lower part of his body alongside the panel and the upper part of his body leaning past the paneltoward the far end. The cited standard,§ 1926.652(a)(1), requires “[e]ach employee in an excavation [to]be protected from cave-ins by an adequate protective system . . . .”In vacating the citation, the judge found: (1)the Secretary failed to establishthattheBrionesemployeeobserved in the trenchwasexposed to a cave-in hazard; and (2) evenif the employee was exposed, it was necessary for the employee to be in the trench in order toinstallthesecond shore. DISCUSSION To establishaviolation of an OSHA standard, the Secretary must provethat:(1) the cited standard applies; (2) its terms were violated; (3) employees were exposed to theviolativecondition; and (4) the employer knew or could have known of theviolativecondition with the exercise of reasonable diligence. See Astra Pharm. Prods., Inc., 9 BNA OSHC 2126, 2129 (No. 78-6247, 1981),aff’d in pertinent part, 681 F.2d 69 (1st Cir. 1982). The only element of the Secretary’s prima facie case on review is employee exposure.1 <#ftn1> I.Employee Exposure Regarding the element of exposure, the COinitiallyclaimed that the protection afforded by thetrench’ssingle installed shore ended at the panel’s edge, butlater statedthat theshore’sprotection extendedpastthe edge of the panel by about one foot.The Secretarymaintains thatthe CO meantthatanextended area of protection exists only whentwoshores have been installed ina trench,butthecontext in which the CO made these statements does not support the Secretary’scontention. In fact, the CO testified that “the shoring . . . gives you a good two to three feet of protection oneither sideof thatone shore,” and that “as you expand out, there’s nothing there for you,” suggesting a circumstance with only one installed shore. (Emphasis added.). We agree with the judge that,giventhis inconsistent and otherwise unsupported testimony, the Secretary has notestablished that the Briones employeein the CO’s photograph—depictedasleaning past the edge of the panel toward the farendof the trench—was past the edge oftheshore’s protection.2 <#ftn2> However, the Commission has recognized that exposure may be established by showing “that it is reasonably predictable either by operational necessity or otherwise (including inadvertence), that employees have been, are, or will be in the zone of danger.” NupreconLP, 23 BNA OSHC 1817, 1819 (No. 08-1307, 2012).Wefindit was reasonably predictablethattheemployeecouldhaveinadvertentlystrayedinto theadjacent,unprotected area of the trench.SeeN. Landing Line Constr. Co., 19 BNA OSHC 1465, 1471 (No. 96-0721, 2001)(exposureestablishedwhere“bracket installation work was so close to . . . energized parts that minimal upward movement, inadvertent or otherwise, would have placed some part of [an employee’s] body closer than[the OSHA standard’s minimum working distance]”). Theemployeewasstanding onunevendirt at theveryedge of thetrench’sprotected area,leaning over whileusinga shovel to clear off a pipelocated inthe unprotected area.Further, his accessto the zone of dangerwasunobstructed. See Brennan v. OSHRC, 513 F.2d 1032, 1039 (2d Cir. 1975) (employee need not be “teetering” on the edge to be “exposed” to the fall hazard).Inthese circumstances,we findthe Secretary has establishedemployeeexposure.3 <#ftn3>SeeN. Berry Concrete Corp., 13 BNA OSHC 2055, 2056 (No. 86-163, 1989) (“[E]mployeeswalked close enough to the floor opening that they could have fallen through.”);compareDelekRef., Ltd., 25 BNA OSHC 1365, 1374-75 (No. 08-1386, 2015) (rejecting argument that employee could be in zone of danger of unguarded shaftby“accidentally trip[ping] and fall[ing],”whentestimony did not “show how close employees actually came to the equipment, and no evidence was adduced regarding conditions on the floor that would make a trip-and-fall reasonably predictable”),appeal docketed, No. 15-60443 (5thCir. June 22, 2015);Buffets, Inc., 21 BNA OSHC 1065, 1067 (No. 03-2097, 2005) (noexposure based on “potential slip hazards”where “employees wore slip-resistant shoes and kept thefloors swept and cleaned”). II.Necessity The judgeagreed withBriones’s contentionthat theemployee’s presence in the trench was “necessary”because in order to install the second shore, Briones had to further excavate the trench, which required uncovering the sewer and gas lines. On review, the Secretary contendsthat:(1)an employer cannot avoid complying with OSHA standards by claiming that employee exposure is somehow necessary;and(2)evenifthat wereso,this argumentis anaffirmativedefensethatBriones waived by failing totimelyraise itbelow.Weneed not reach the Secretary’s claim thatthis argument is not a valid defense,however,becauseeven if it were, itisan affirmative defensefor whichBrionesbearstheburden of proof, whichithas notsatisfied.4 <#ftn4> Sucha defense, if valid,isan affirmativedefensebecause proof that employee exposure was “necessary” to installsafety equipmentwould defeat the citation even if the Secretary established his prima facie case.SeeStarcraftCo. v. C.J. Heck Co. of Tex., 748 F.2d 982, 990 n.11 (5th Cir. 1984) (affirmative defenserequiresdefendantto“rely on new matters to extinguish the plaintiff’s claim”);U.S. Postal Serv.,24 BNA OSHC2067,2068(No. 08-1547, 2014) (affirmative defense “rais[es] arguments or new facts that, if proven, defeat a plaintiff’s claim even if the allegations inthe complaint are true”). As an affirmative defense,Brionesbearsthe burden of proving thatitsemployee needed to be in the trench to install the second shore. The CO’s unrebutted testimonyin explaining the installation process, however, establishes that the shoring Briones used isspecificallydesigned to be installed from outside the trench. With respect to the company’s contention thatthe employee “descended into the trench briefly to clear dirt off the pipe and most importantly to pick up the chain that was being used to lowerthe second shore into place,”therecordlacks any evidenceshowingthat the pipes had to be uncoveredorcleaned in order to expand the excavationtoinstall the second shore. In fact,Briones’s ownertestifiedthat the company’s excavatorhad a “plate in the front” to avoid“br[eaking] the utility,”whichsuggeststhatBriones could use theexcavator to deepenthetrenchwithout first uncovering the pipes.In short,contrary to the company’s claim,therecorddoes notshow thatit was necessary forthe employeetouncover the pipesin order toinstall the second shore. As toretrieval of the chain, there is no evidence that thechain waslocatedin the unprotected area of the trench—indeed, Briones does not even assert where in the trench the chain was located—sothere isnoevidencethat the employee needed to be at the edge of the protected area to retrieve it. Noris there any evidencethat Briones could not have used another chain to install the second shore. In sum,the recordfails toshowthatit was necessary for Briones’semployee to be in the trench at all,let alonethat he needed to beat the edge of the first shoreso asto install the second shore. Therefore,wereject thejudge’snecessityfindingandaffirm the citation.5 <#ftn5> III.Characterization and Penalty The Secretary characterized theviolationas serious. Under theOccupationalSafety andHealthActof 1970, 29 U.S.C. §§ 651-678, a violation is serious “if there is a substantial probability that death or serious physical harm could result from” aviolativecondition. Section 17(k),29 U.S.C. § 666(k). The CO testifiedthatthe7-foot-deep trench with inadequate cave-in protection created a substantial probability of serious injury,such as“fractures, broken bones, and death.” There is norecordevidence contradictingthis testimony. Accordingly, we affirm the serious characterization of the violation. Regarding penalty,the Actrequires that“due consideration”be given to the employer’s size, the gravity of the violation, the good faith of the employer, and any prior history of violations. Section 17(j),29 U.S.C. § 666(j);Jim Boyd Constr., Inc., No. 11-2559, slip op. at 8 (OSHRC Nov. 16, 2016);Capform, Inc., 19 BNA OSHC 1374, 1378 (No. 99-0322, 2001),aff’d, 34 F.App’x152 (5th Cir. 2002) (unpublished). In determiningthe $1,225proposed penalty here, the Secretarycalculateda gravity-based penalty of $3,500, and then gave Briones a 40-percent reduction for size, a 15-percent reduction for good faith because the violation was abated during the inspection, and a 10-percent reduction forlack of priorhistory. Wefind thata $1,000 penaltyis appropriate.Inreaching this conclusion, Chair Attwood relies on all of the circumstances in light of the statutory factors, including the gravity of the violation, Briones’ssmallsize, and good faith in instructing employees to remain inside the protected area as it also prepared toinstall the second shore. See Aviation Constructors, Inc., 18 BNA OSHC 1917, 1920 (No. 96-0593, 1999) (finding good faith for penalty purposeswhere employer “clearly intended that employees be protected by shoring” and “selected a system configured for the particular worksite in accordance with one of the options permitted under the standard”). Additionally, regardingthegravityof the violation,Commissioner MacDougallfurthernotes thatonlyone employee was exposed for a short duration,the likelihood of serious injury was lowgiven that theemployee was notphysicallyin the unprotected area of the trench at the time of the violation, and even if he were to momentarily transgress into the unprotected area, he could return to the protected area with a low likelihood of injury.6 <#ftn6>SeeCapform, 19 BNA OSHC at 1378 (gravity is the primary consideration and is determined by the number of employees exposed, the duration of the exposure, the precautions taken against injury, and the likelihood of an actual injury). ORDER We affirm Citation 1, Item 1 asserious, and assess a penalty of $1,000. SO ORDERED. /s/ Cynthia L. Attwood Chairman /s/ Dated: December 14, 2016 Heather L. MacDougall Commissioner UNITED STATES OF AMERICA OCCUPATIONAL SAFETY AND HEALTH REVIEW COMMISSION SECRETARY OF LABOR, Complainant, v. BRIONES UTILITY COMPANY, Respondent. OSHRC DOCKET NO. 10-1372 Appearances: Elizabeth M. Kruse, Esq., Office of the Solicitor, U.S. Department of Labor, Dallas, Texas For Complainant Edward L. Piña, Esq., Edward L.Piña& Associates, P.C., San Antonio, Texas For Respondent Before: Administrative Law Judge John H. Schumacher DECISION AND ORDER PROCEDURAL HISTORY This proceeding is before the Occupational Safety and Health Review Commission (“the Commission”) pursuant to Section 10(c) of the Occupational Safety and Health Act of 1970, 29 U.S.C. §651et seq.(“the Act”). The Occupational Safety and Health Administration (“OSHA”) conducted an inspection of a Briones Utility Company (“Respondent”) worksite in San Antonio, Texas on May 12, 2010. As a result of the inspection, OSHA issued a Citation and Notification of Penalty (“Citation”) to Respondent alleging two (2) violations of the Act and proposed a total penalty of $1750.00.7 <#ftn7>Respondent filed a timely notice of contest, bringing this matter before the Court. A hearing was held on January 5, 2012 in San Antonio, Texas. Both parties have filed post-trial briefs. JURISDICTION Based upon the record, I find that Respondent was engaged in a business affecting commerce and was an employer within the meaning of sections 3(3) and 3(5) of the Act.8 <#ftn8>Therefore, I conclude that the Occupational Safety and Health Review Commission has jurisdiction over the parties and subject matter in this case pursuant to Section 10(c) of the Act.9 <#ftn9> DISCUSSION On May 12, 2010, ComplianceSafety and Health Officer (“CSHO”)RaulCarillodrove past Respondent’s worksite, which was located near a car lot at the intersection of PerrinBeitelandVesperoin San Antonio, Texas. (Tr. 19). As he drove by, the CSHO observed an open trench. (Tr. 19). Due to the potentially deadly hazards posed by trenches, OSHA has a National Emphasis Program regarding trenching and excavations. (Tr. 19). Pursuant to that program, it is OSHA’s policy for a compliance officer to conduct an inspection when he observes trenching operations taking place. (Tr. 19–20). In this particular case, the CSHO conducted an inspection of Respondent’s worksite, which resulted in the Citation at issue in this matter. Respondent is owned by Alfredo Brionesand its primary business is underground utility excavation and trenching. (Tr. 19, 22, 133). On the day of the inspection, Respondent was excavating a trench to expose a sewer and gas line conflict for San Antonio Sewer and Water (“SAWS”) and City Public Service (“CPS”). (Tr. 97, 133, 135–36). In order to uncover the conflicting pipes, Respondent had excavated a ten-foot long trench.10 <#ftn10>(Tr. 136–37). When the CSHO arrived at Respondent’s worksite, he got out of his car and began to take photographs of the trench and surrounding conditions. (Tr. 20–21). The pictures reveal that shoring had beeninstalled for approximately four feet along the ten-foot long trench. (Tr. 23, 55, C-2, C-7). The remaining portion of the trench did not have shoring installed, but Respondent had rented additional shores, which were located in close proximity to the trench. (Tr. 21, 146). At the end of the trench protected by shoring, Respondent had installed a ladder to access and exit the trench. (Tr. 78, C-2). At the time of the CSHO’s arrival on the site, Respondent’s employee, Armando Briones, was working in the trench.11 <#ftn11>(Tr. 103–104, 121). Although there was some disagreement as to what Armando was doing in the trench, the weight of the evidence suggests that he was using a shovel to uncover the sewer and gas lines.12 <#ftn12>(Tr. 121, 124, 149). Even though he was standing between the shoring panels in the trench, Armando was observed leaning just outside of the panels while using the shovel. (C-7). Once he had taken pictures of the trench, the CSHO instructed Armando to get out of the trench, identified himself as a compliance officer for OSHA, and proceeded to conduct an opening conference. (Tr. 21). At the conclusion of the opening conference, the CSHO took some more pictures, measured the trench, and collected a soil sample from the spoil pile. (Tr. 22). The CSHO identified potential violations, including the violation that led to the present Citation, and gave Respondent the opportunity to abate those violations during the inspection, which Respondent did. (Tr. 23, 147). The CSHO ended the inspection with aclosing conference and notified Respondent of the potential for the issuance of a citation and monetary penalties. (Tr. 23). THE ALLEGED VIOLATION – 29 C.F.R. § 1926.652(a)(1) Complainant alleges in Citation 1, Item 1 that: On or about 5/12/10, at the worksite, employees were exposed to a cave in hazard while they worked inside a trench which measured 7 feet deep, 3 feet wide, and 20 feet long. The company had only one shore and was not adequate to prevent a cave in from occurring. The cited standard provides: (a)Protection of employees in excavations.(1) Each employee in an excavation shall be protected from cave-ins by an adequate protective system designed in accordance with paragraph (b) or (c) of this section except when: (a)Excavations are made entirely in stable rock; or (i)Excavations are less than 5 feet (1.52m) in depth and examination of the ground by a competent person provides no indication of a potential cave-in. FINDINGS OF FACT AND CONCLUSIONS OF LAW To establish aprima facieviolation of the Act, the Secretary must prove: (1) the standard applies to the cited condition; (2) the terms of the standard were violated; (3) one or more of the employees had access to the cited condition; and (4) the employer knew, or with the exercise of reasonable diligence could have known, of theviolativecondition. OrmetCorporation, 14 BNA OSHC 2134, 1991 CCH OSHD ¶ 29,254 (No. 85-0531, 1991). To establish employer knowledge, an employer does not have to possess knowledge that a condition violated the Act, just knowledge that the condition existed. Shaw Construction, Inc., 6 BNA OSHC 1341, 1978 CCH OSHD ¶ 22,524 (No. 3324, 1978). Further, the Secretary need not show that “an employer understood or acknowledged that the physical conditions were actually hazardous.” Phoenix Roofing, Inc., 17 BNA OSHC 1076, 1079–80 (No. 90-2148, 1995),aff’d without published opinion, 79 F.3d 1146 (5th Cir. 1996). A violation is “serious” if there is a substantial probability that death or serious physical harm could result from theviolativecondition. 29 U.S.C. 666(k). Complainant need not show that there is a substantial probability that an accident will occur; she need only show that if an accident occurred, serious physical harm could result. If the possible injury addressed by the regulation is death or serious physical harm, a violation of the regulation is serious.Phelps Dodge Corp. v. OSHRC, 725 F.2d 1237, 1240 (9th Cir. 1984);Dec-Tam Corp., 15 BNA OSHC 2072 (No. 88-0523, 1993). Applicability of the Standard There is no dispute that the trench found at Respondent’s worksite is an excavation covered by the regulations found in Subpart P. Further, the evidence clearly establishes that the exceptions to the standard do not apply. First, although there was some dispute as to whether the soil was properly classified as Type B or Type C, the trench was clearly not made in stable rock. (Tr. 28, 49). Second, the CSHO measured the trench and found it to be approximately seven (7) feet deep. (Tr. 26). Alfredo testified that he also believed that the trench was approximatelyseven feet deep. (Tr. 138). Accordingly, the Court finds that the cited standard applies to the condition indicated in Citation 1, Item 1. Whether the Terms of the Standard Were Violated If the exceptions to the standard do not apply, 29 C.F.R. § 1926.652(a)(1) requires an employer to use an “adequate protective system,” designed in accordance with subsections (b) or (c), to protect employees from a cave-in. Whether a particular protective system is considered adequate depends on the type of system an employer chooses. If the employer utilizes sloping or benching, then the employer refers to subsection (b) to determine the proper design parameters. If the employer utilizes shoring or shield systems, then it must refer to subsection (c), which provides the design parameters for such systems depending on soil type. There are four design criteria options available to employers if they utilize the protections provided in subsection (c): (1) OSHA tabulated data; (2) tabulated data from the manufacturer of the protective system; (3) tabulated data approved by a professional engineer; or (4) tabulated data created by a professional engineer. (Tr. 60–70, C-5). This data includes the minimally acceptable measurements for installing shoring, including: (1) the depth of the trench; (2) the vertical distance of the shore (measured from the floor to the hydraulic cylinder); and (3) the horizontal distance between hydraulic cylinders. (Id.). The determination of which set of data to use is contingent upon the type of soil present within the trench. (Tr. 61, C-5). Respondent implemented a shoring system that utilized hydraulic cylinders or pistons that were oriented vertically and exerted pressure on opposite sides of the trench wall. These cylinders were pressed against vertical piece of aluminum, known as awaler. (Tr. 53). Thewalers, in turn, were placed in the center of composite sheets13 <#ftn13>, known as fin forms, which measured four feet in width by approximately8 feet in height. (Tr. 50, 55, C-2, C-7). The cylinders are placed in the center of the fin forms and do most of the work of holding up the trench walls; however, the fin forms serve to disperse the pressure of the cylinders across a greater area and prevent sloughing and raveling of the walls. (Tr. 55). At the time of the inspection, only one set of cylinders and fin forms were in Respondent’s trench. (Tr. 65). Based upon his on-site observations, the CSHO determined that the trench was dug in Type B soil, which was also the determination of Respondent. (Tr. 29, 153). He also took a sample of the soil from the spoil pile, which was sent in to OSHA’sTechnical Centerin Salt Lake City, Utah. (Tr. 31, 37). The subsequent lab tests revealed that the soil was, in fact, Type C.14 <#ftn14>Type C soil is the most unstable of the soil types and, therefore, typically requires rather strict design parameters in the construction of a shoring or shield system. In fact, with respect to the particular shoring system utilized by Respondent, OSHA does not provide tabulated data. Accordingly, it was incumbent upon Respondent to utilize the manufacturer’s tabulated data to determine the proper measurements for the shoring system used in its trench. (Tr. 67–71). No evidence was introduced at trial as to what the manufacturer’s recommendations were. Complainant contends that Respondent violated 29 C.F.R. § 1926.652(a)(1) because Respondent had not installed an adequate protective system in the cited trench. Respondent only had one shore in the ten-foot long trench, which, according to Complainant, left eight feet of open, unprotected trench. (Sec’yBrief at p. 9 n. 9). In order to comply with the standard, Complainant argues that Respondent needed to install a second shore such that the hydraulic cylinders were spaced approximately four to six feet apart (horizontal distance). Although the manufacturer’s data was not introduced into evidence, the CSHO testified that, for Type B soil, OSHA requires a horizontal distance of eight feet. (Tr. 63–64, 69). See also29 C.F.R. 1926.652tbl. D. He further testified that he has seen manufacturer’s tabulated data for Type C soil and that it typically requires a horizontal distance of approximately four to six feet. (Tr. 67). Respondent argues that it did not violate trenching standard because it was still in the process of installing additional shoring at the time of the OSHA inspection. The primary thrust of Respondent’s argument is that the slope at the unprotected end of the trench prevented the fin forms from fitting properly and that additional material needed to be removed before the shoring could be installed. Respondent further points out that it had sufficient additional shores available on sight and that the second shore was ready to be installed. (Tr. 147, 158). It is clear that a portion of the trench was unprotected and, thus, insofar as the standard is concerned, a complete “system” of shoring had not yet been installed. That said, the Court believes that a work in progress cannot be viewed in the same way as the finished product. If work was being conducted in the unprotected end of the trench, then there would clearly be a violation, as the worker would not be “protected from cave-ins” asthe standard requires.However, to the extent that Complainant is arguing that Respondent violated the standard because it failed to have a complete shoring system in thetrench—whichwas being prepped for theinstallation of additional shores—regardless of whether any employees were actually exposed, the Court refuses to find that a violation occurred. That being said, the Court is mindful of the fact that Armando was in the trench at the time of the inspection. Thus, we have a case where the elements of violating the terms of the standard and exposure to the hazard/condition cannot be resolved independently of one another. SeeOrmet, 14 BNA OSHC 2134(listing the elements of aprima facieviolation of the Act). In order to answer the question of whether Respondent’s employees were protected from cave-ins and thus, whether a violation occurred, the Court must address Armando’s position in the trench and theeffectiveness of the existing shoring. As noted earlier, Armando was in the trench in order to identify the location of the sewer and gas pipes. (Tr. 121, 124, 129). The pictures taken by the CSHO clearly show that Armando was standing at the threshold of the existing shoring with his upper torso leaning slightly outside of the fin form. (C-7). Complainant contends that Armando’s position exposed, at the very least, his upper body to the potential of a trench cave-in because he was outside the protective area of the shoring. Further, Complainant argues that Armando was exposed to the condition for at least five minutes, which represents the length of time between when the CSHO arrived on site and when he asked Armando to exit the trench.(Tr. 59). Respondent argues that Armando was notoutside the protective area of the shoring, and if he was, it was only for a few seconds while he responded to the CSHO’s request that he pick up the shovel.15 <#ftn15> According to Complainant, Respondent’s trench was unprotected or “open” for a distance of eight feet. (Tr.65,Sec’yBrief at p. 9). This is based upon the fact that the trench extended eight feet beyond the first, and only, hydraulic cylinder. This point is well-taken because the CSHO testified that “one shore itself cannot retain anything outside of it without another support system.” (Tr. 76). In other words, the second shore applies pressure to the trench wall at the point where the pressure from the first shore ends. The CSHO also testified, however, that “the shoring, it gives you a good two to three feet of protection on either side of that one shore, for that area.” (Tr. 76). Thus, the pressure from the shore in this case was effective at least to the extent of the fin forms, which extended two feet on either side of the cylinder. (Tr.57–58). Determining the effective area of the shoring is further complicated by the fact that no evidence was introduced as to what the manufacturer’s tabulated data required in terms of the horizontal spacing of the cylinders. As stated earlier, OSHA requires a maximum horizontal distance of eight feet between cylinders in Type B soil. In other words, OSHA has determined that for shores used in trenches dug in Type B soil, the effective area of protection provided by shores is approximately four feet in either direction. The soil at Respondent’s worksite, however, was determined to be Type C.16 <#ftn16>(Tr. 31, 49, C-1). The CSHO’s testimony and common sensedictate that the effective area of protection provided by shores in Type C soil would be less. (Tr. 67). How much less, however, is determined by the manufacturer’s tabulated data, which was not introduced into evidence. The CSHO testified that the manufacturer’s tabulated data for shoring of the type used by Respondent typically requires a maximum horizontal distance between four and six feet. (Tr. 67). This comports with the CSHO’s understanding that the shoring “gives you a good two to three feet of protection on either side of that one shore . . . .” (Tr. 76). Without a more definitive understanding of the protective area of the existing shoring, the Court cannot find that Complainant has proven, by a preponderance of theevidence, thatArmando was outside the protective area of the existing shoring. If the manufacturer’s tabulated data required a horizontal spacing of four feet, then the protective area of the shoring would be approximately two feet on either side; however, if the data required spacing of six feet, then the protective area would be approximately three feet on either side. The photographs submitted by Complainant illustrate that Armando was making a point to position his body within the existing shoring, which confirms the testimony of Alfredo, who stated that “I never send boys because, if no shore, they cannobe inside.” (Tr. 154). Based uponthe testimony regarding the width of the fin forms, and considering the evidence regarding the protective range of the shoring, the Court cannot find that Complainant proved that Armando’s position at or near the threshold of that protective range exposed him to the potential for a cave-in.17 <#ftn17> Notwithstanding the above, Complainant also seems to argue that Armando’s mere presence inside a trench that has incomplete shoring exposed him to the hazard of a potential cave-in. This line of argument addresses the question of what constitutes an “adequate protective system” pursuant to 29 C.F.R. 1926.652(a)(1). The term “protective system” is defined as a “method of protecting employees from cave-ins from material that could fall or roll from an excavation face or into an excavation . . . . Protective systems include support systems, sloping and benching systems, shield systems, and other systems that provide the necessary protection.” 29 C.F.R. 1926.650(b). More specifically, a “shoring system” is defined as “a structure such as metal hydraulic, mechanical, or timber shoring system that supports the sides of an excavation and is designed to prevent cave-ins.” Id.These definitions can apply with equal force to both an individual shore as well as a series of them; the key to any “protective system,” as it were, is that it protects employees from a cave-in. The Court finds that the shoring installed by Respondent constituted such a system. The fact that the entire trench was not shored does not mean that it is a violation to have an individual standing within the protective area of a single shore. See General Motors Corp., 12 BNA OSHC 1324 (No. 80-5439, 1985) (“Inasmuch as the employees in the north-south leg were either working in a part of the trench that had already been shored or were engaged in installing the shoring in that leg, GM did not violate the standard in the north-south leg.”);see also Adams & Mulberry Corp., 3 BNA OSHC 1077 (No. 2548, 1975) (“[I]f the two employees had been working from the braced portion of the trench, we would vacate.”). Although the violations in these two cases involved a different version of the present standard, the Court finds that the standards address the same hazard and the methods to protect against that hazard. SeeOccupational Safety and Health Standards—Excavations 54 Fed Reg. 45,894, 45,928 (Oct. 31, 1989). It should be pointed out that theGeneral Motorscase cited above also stands for the proposition that an employer’s failure to “limit employee access to the trench so as to eliminate the unnecessary exposure of employees to theunshoredwalls” constitutes a violation. General Motors, 12 BNA OSHC 1324. Those circumstances are arguably present here, where Armando was not physically prevented from accessing theunshoredportion of the trench. However, there are some key distinctions to be made. First, the only way to access and exit the trench in theGeneral Motorscase involved traveling through an unprotected portion of the trench. Id.In this case, however, the ingress/egress point was well within the protection of the existing shoring. (C-2). Secondly, although no physical barrier was in place at the end of the existing shoring, it seems clear that it was Respondent’s policy that employees do not work in a trench without proper protection. (Tr. 154, 158). Based upon the position of Armando’s body in Exhibit C-7, it appears as if that policy was followed. (C-7). Finally, even if the Court were to find the slightest hint of exposure, it cannot say that such exposure was unnecessary as the Commission determined inGeneral Motors, wherein employees were exposed to cave-ins at the access/egress point. See General Motors, 12 BNA OSHC 1324 (“[T]he question is whether employee presence in the trench is needless.”). Alfredo testified that Armando was uncovering the sewer and gas pipes because further excavation was needed to install additional shoring. (Tr.149, 166).Thus, the actions of Armando were calculated to facilitate the installation of shoring that was readily available and would provide additional protection. At bottom, although Complainant showed that Respondent’s employee was leaning just beyond the threshold of the fin form, the Court finds that Complainant failed to establish that Respondent’s employee was outside of the protective area of the existing shoring system such that he was exposed to the hazard of a cave-in. The presence of additional shoring near the trench indicates that Respondent was taking appropriate measures to protect its employees from the hazard of a trench cave-in,and the testimony of Respondent’s witnesses indicates that Respondent stressed the importance of working within existing shoring. Accordingly, the Court finds that Complainant has failed to establish, by a preponderance of the evidence, a violation of 1926.652(a)(1). ORDER Based upon the foregoing Findings of Fact and Conclusions of Law, it is ORDERED that: 1.Citation 1, Item 1 is VACATED. /s/ _____________ John H. Schumacher Judge, OSHRC Date: July 9, 2012 Denver, Colorado ------------------------------------------------------------------------ " <#ftnref-1> <#ftnref0> 1 <#ftnref1>Asthe judgefound,the trench at Briones’s worksite was an excavation covered by the standard. There is also no dispute that only part of the trench was protected by hydraulic shoring.Although the judge vacatedthe citationwithout reaching the issue of knowledge, the record shows thatBriones’s owner was at the worksite at the time of the alleged violation, and he testified that the company was going to install the second shore, showing his awareness that a portion of the trench lackedrequiredshoring.See A.P.O’HoroCo., 14 BNA OSHC 2004, 2007 (No. 85-369, 1991) (actual knowledge established through foreman who “observed the trenching process”). 2 <#ftnref2>Indeed, the CO failed to explain the basisof his opinion on theissue of whether the protection afforded by the shoring extended past the panel. SeeHurlock RoofingCo.,7 BNA OSHC 1108, 1111 (No. 76-357, 1979)(declining to credit opiniontestimonythat was not explained and for which no basis was given).Additionally, as the judge noted, the record lacks the shoring manufacturer’s tabulated data. 3 <#ftnref3>CommissionerMacDougall notes that her conclusion in this regard is limited to the facts beforethe Commissionand that she views theholdingin this case as a narrow one. In particular, she notes that the company placed no visual or physical barrier (such as caution tape, a cone, a barricade, or the like) between the protected and unprotected areas of the trench. 4 <#ftnref4>As to waiver, both partieselicited testimonyat the hearing regardingwhy the employee was in the trench, and the Secretary specifically introduced evidencethat the shoringsystem can be installed from outside the trench.SeeFed. R. Civ. P. 15(b)(2) (“When an issue not raised by the pleadings is tried by the parties’ . . . implied consent, it must be treated in all respects as if raisedin the pleadings . . . .”);TexlandDrilling Corp., 9 BNA OSHC 1023, 1026 n.8 (No. 76-5307, 1980) (finding implied consent where the party claiming waiver introduced evidence relevant to theunpleadedaffirmative defense). Therefore, we reject the Secretary’s claim. 5 <#ftnref5>Brionesalsoclaimsthat the judge improperly admitted evidence regarding the classification of the trench’s soil, and “coached” the Secretary’s counsel at the hearing inthe means by whichsuch evidence could be admitted. However, given that soil type is relevant to whether a protective system is necessary,see29 C.F.R. § 1926.652(a) &app. D, andBriones does not argue that a protective system was unnecessary, these evidentiary objections are moot. 6 <#ftnref6>Commissioner MacDougallcontrasts the facts here with, for example,an employeeinthe zone of dangerposed byan unprotectedroof edge or floor opening—in that circumstance, the likelihood of injury is greater, making the gravity of the violation higher. 7 <#ftnref7>.Only one of the violations is at issue in the present case. On December 9, 2011, the parties filed a Joint Notice of Partial Withdrawal of Citation. The Secretary withdrew Citation 1, Item 2. Accordingly, only Citation 1, Item 1 is before the Court. 8 <#ftnref8>. The Commission has held that construction activity, even a small project, affects interstate commerce. Clarence M. Jones, 11 BNA OSHC 1529, 1531 (No. 77-3676, 1983). In this case, evidence was introduced that Respondent leased shoring equipment that was produced outside of the state of Texas from a company called National Trench Safety. 9 <#ftnref9>. Respondent did not dispute that it is an employer under the Act, nor did it dispute that the Commission has jurisdiction in this matter. 10 <#ftnref10>. The Citation originally indicated that the trench at issue was twenty feet long. (R-1). The CSHO clarified that this measurement was inaccurate and that the length of the trench was actually ten feet. (Tr. 27). 11 <#ftnref11>. Armando Briones is the brother of Respondent’s owner, Alfredo Briones. For the purposes of clarity, the Court shall refer to them individually as Armando and Alfredo. 12 <#ftnref12>. At one point, Armando testified that the CSHO told him to pick up a shovel that was resting on the ground in theunshoredportion of the trench. (Tr. 109). Later in his testimony, however, he indicated that he was using the shovel to uncover the sewer and gas lines. (Tr. 121, 124). This was later confirmed by Alfredo, who stated that Armando was “touching the pipe [to] be sure it’s there.” (Tr. 149). The photograph taken by the CSHO appears to support this description of Armando’s actions within the trench. C-7). 13 <#ftnref13>. The CSHO testified that the sheets were made out of plywood, whereas Alfredo stated that they were made of something more substantial. (Tr. 50, 139). The determination of what the fin forms were made of is of no consequence to this matter; however, the Court accepts the testimony of Alfredo that the fin forms were made of something more substantial than plywood, as he was the individual who rented the shoring equipment. 14 <#ftnref14>. The lab report was admitted into evidence over Respondent’s objection on the basis of hearsay. The Court found and still holds that the report fell under one of two exceptions to the hearsay rule: FRE 803(6) and 803(8). Further, the Court finds no issue with the fact that the CSHO used a sampling sheet entitled “Air Sampling Worksheet” because the CSHO testified that sheet is routinely used for such samples. 15 <#ftnref15>. For the reasons previously mentioned, the Court finds that the CSHO did not ask Armando to pick up the shovel. The Court agrees that it would not make sense for the CSHO to ask Armando to engage in an activity that could potentially expose him to a safety hazard. (Tr. 171). 16 <#ftnref16>. At one point, both Armando and Alfredo testified that the unprotected portion of the wall on Armando’s right side in Exhibit C-7 was covered in concrete, which Respondent argues provided additional support. (Tr. 117, 160). The CSHO testified that he made no such observation. That being said, even if the Court found that one of the walls was concrete, the other wall was still previously disturbed, Type C soil. Because it only takes the collapse of one wall to cause injury, this fact plays no part in the Court’s decision. 17 <#ftnref17>.Furthermore, although the Court is mindful of the fact that a cave-in can happen in a matter of seconds, the Court cannot find that the period of exposure (five minutes) suggested by the CSHO is anything more than speculation. To be sure, Armando was in the trench during the period of time from when the CSHO arrived until he was asked to exit the trench; however, that does not equate to the amount of time he may or may not have been leaning outside the protective area of the shoring. Considering that the Court has not found that merely being in a trench without a full complement of shores is a violation, the Court cannot say that Armando was “exposed” for any longer than the time directly observed by the CSHO.
