I agree with Judge Watkins\u2019 interpretation of the standard. Moreover, I agree with the precise language employed by the Judge in making this holding.\t\t\t\t\t\t\t\t\t\tJudge Watkins said:\t\t\t\t\t\t\t\t\t\tIt should be noted here\u2014as in the\t\t\t\t\t\tConsolidated Pine\t\t\t\t\t\tcase\u2014that this is not a holding that the trim saws were adequately guarded.

It is also alleged that on the same day there were two violations not of a serious character, one involving the absence of a cover on a floor opening (29 CFR 1910.23(a)(5)) and the other a failure to guard belts, pulleys, gears, shafts and other moving parts of woodworking machinery.

(i) Wood guards may be used in the woodworking and chemical industries, in industries where the presence of fumes or where manufacturing conditions would cause the rapid deterioration of metal guards; also in construction work and in locations outdoors where extreme cold or extreme heat make metal guards and railings undesirable. In all other industries, wood guards shall not be used.\t\t\t\t\t\t\t\t\t\t(ii) (a) Wood shall be sound, tough, and free from any loose knots.\t\t\t\t\t\t\t\t\t\t(b) Guards shall be made of planed lumber not less than one (1) inch rough board measure, and edges and corners rounded off.\t\t\t\t\t\t\t\t\t\t(c) Wood guards shall be securely fastened together with wood screws, hardwood dowel pins, bolts, or rivets.\t\t\t\t\t\t\t\t\t\t(d) While no definite dimensions are given under this heading for framework or filler materials, wood guards shall be equal in strength and rigidity to metal guards specified in subparagraphs (1)(i) and (ii) of this paragraph and Table O\u201312.\t\t\t\t\t\t\t\t\t\t(e) For construction of standard wood railing, see subparagraph (5) of this paragraph.\t\t\t\t\t\t\t\t\t\t(3) Guards for horizontal overhead belts. (i) Guards for horizontal overhead belts shall run the entire length of the belt and follow the line of the pulley to the ceiling or be carried to the nearest wall, thus enclosing the belt effectively. Where belts are so located as to make it impracticable to carry the guard to wall or ceiling, construction of guard shall be such as to enclose completely the top and bottom runs of belt and the face of pulleys.\t\t\t\t\t\t\t\t\t\t(ii) The guard and all its supporting members shall be securely fastened to wall or ceiling by gimlet-point lag screws or through bolts. In case of masonry construction, expansion bolts shall be used. The use of bolts placed horizontally through floor beams or ceiling rafters is recommended.\t\t\t\t\t\t\t\t\t\t\u00a0\t\t\t\t\t\t\t\t\t\tTABLE O\u201312\u2013TABLE OF STANDARD MATERIALS AND DIMENSIONS\t\t\t\t\t\t\t\t\t\t\u00a0\t\t\t\t\t\t\t\t\t\t\u00a0\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\tMaterial\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\u00a0\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\u00a0\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\tClearance from moving part at all points\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\u00a0\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\u00a0\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\tLargest mesh or opening allowable\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\u00a0\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\u00a0\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\tMinimum gauge (U.

Overhead rope drive and block and roller-chain-drive guards shall be not less than six (6) inches wider than the drive on each side. In overhead silent chain-drive guards where the chain is held from lateral displacement on the sprockets, the side clearances required on drives of twenty (20) inch centers or under shall be not less than one-fourth inch from the nearest moving chain part, and on drives of over twenty (20) inch centers a minimum of one-half inch from the nearest moving chain part.\t\t\t\t\t\t\t\t\t\t(iv) Table O\u201313 gives the sizes of materials to be used and the general construction specifications of guards for belts ten (10) inches or more in width.

Guards for horizontal overhead rope and chain drives. Overhead-rope and chain-drive guard construction shall conform to the rules for overhead-belt guard construction of similar width, except that the filler material shall be of the solid type as shown in Table O\u201313, unless the fire hazard demands the use of open construction. A side guard member of the same solid filling material should be carried up in a vertical position two (2) inches above the level of the lower run of the rope of chain drive and two (2) inches within the periphery of the pulleys which the guard encloses thus forming a trough. These side filler members should be reinforced on the edges with 1 1\/2-inch by 1\/4-inch flat steel, riveted to the filling material at not greater than eight (8) inch centers; the reinforcing strip should be fastened or bolted to all guard supporting members with at least one 3\/8-inch rivet or bolt at each intersection, and the ends should be secured to the ceiling with lag screws or bolts. The filling material shall be fastened to the framework of the guard and the filler supports by 3\/16-inch rivets spaced on 4-inch centers. The width of the multiple drive shall be determined by measuring the distance from the outside of the first to the outside of the last rope or chain in the group accommodated by the pulley.\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t(5) Guardrails and\t\t\t\t\t\ttoeboards. (i) Guardrail shall be forty-two (42) inches in height, with\t\t\t\t\t\tmidrail\t\t\t\t\t\tbetween top rail and floor.\t\t\t\t\t\t\t\t\t\t(ii) Posts shall be not more than eight (8) feet apart; they are to be permanent and substantial, smooth, and free from protruding nails, bolts, and splinters. If made of pipe, the post\t\t\t\t\t\tshall be one and one-fourth (1 1\/4) inches inside diameter, or larger. If made of metal shapes or bars, their section shall be equal in strength to that of one and one-half (1 1\/2) by one and one-half (1 1\/2) by three-sixteenths (3 1\/4 16) inch angle iron. If made of wood, the posts shall be two by four (2 x 4) inches or larger. The upper rail shall be two by four (2 x 4) inches, or two one by four (1 x 4) strips, one at the top and one at the side of posts. The\t\t\t\t\t\tmidrail\t\t\t\t\t\tmay be one by four (1 x 4) inches or more. The rails (metal shapes, metal bars, or wood), should be on that side of the posts which gives the best protection and support. Where panels are fitted with expanded metal or wire mesh as noted in Table O\u201312 the middle rails may be omitted. Where guard is exposed to contact with moving equipment, additional strength may be necessary.\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t(iii)\t\t\t\t\t\tToeboards\t\t\t\t\t\tshall be four (4) inches or more in height, of wood, metal, or of metal grill not exceeding one (1) inch mesh.\t\t\t\t\t\tToeboards\t\t\t\t\t\tat flywheel pits should preferably be placed as close to edge of the pit as possible.\t\t\t\t\t\t\t\t\t\t(p) Care of equipment\u2014(1) General. All power-transmission equipment shall be inspected at intervals not exceeding 60 days and be\t\t\t\t\t\tkept in good working condition at all times.\t\t\t\t\t\t\t\t\t\t(2) Shafting. (i) Shafting shall be kept in alignment, free from rust and excess oil or grease.\t\t\t\t\t\t\t\t\t\t(ii) Where explosives, explosive dusts, flammable vapors or flammable liquids exist, the hazard of static sparks from shafting shall be carefully considered.\t\t\t\t\t\t\t\t\t\t(3) Bearings. Bearings shall be kept in alignment and properly adjusted.\t\t\t\t\t\t\t\t\t\t(4) Hangers. Hangers shall be inspected to make certain that all supporting bolts and screws are tight and that supports of hanger boxes are adjusted properly.\t\t\t\t\t\t\t\t\t\t(5) Pulleys. (i) Pulleys shall be kept in proper alignment to prevent belts from running off.\t\t\t\t\t\t\t\t\t\t(ii) One or both pulleys carrying a\t\t\t\t\t\tnonshifting\t\t\t\t\t\tbelt should have crowned faces.\t\t\t\t\t\t\t\t\t\t(iii) Cast-iron pulleys should be tested frequently with a hammer to disclose cracks in rim or spokes. It should be borne in mind that the sound is usually the pulley.\t\t\t\t\t\t\t\t\t\t(iv) Split pulleys should be inspected to ascertain if all bolts holding together the sections of the pulley are tight.\t\t\t\t\t\t\t\t\t\t(6) Care of belts. (i) Quarter-twist belts when installed without an idler can be used on drives running in one direction only. They will run off a pulley when direction of motion is reversed.\t\t\t\t\t\t\t\t\t\t(ii) Inspection shall be made of belts, lacings, and fasteners and such equipment kept in good repair.\t\t\t\t\t\t\t\t\t\t(iii) Where possible, dressing should not be applied when belt or rope is in motion; but, if this is necessary, it should be applied where belts or rope leave pulley, not where they approach. The same precautions apply to lubricating chains. In the case of V-belts, belt dressing is neither necessary nor advisable.\t\t\t\t\t\t\t\t\t\t(7) Lubrication. The regular oilers shall wear tight-fitting clothing and should use cans with long spouts to keep their hands out of danger. Machinery shall be oiled when not in motion, wherever possible.\t\t\t\t\t\t\t\t\t\tThe hearing was held in Prineville, Oregon September 7, 1972. Although there was full compliance with procedural requirements for notice to additional parties, none appeared.\t\t\t\t\t\t\t\t\t\tThe principal question in the case involves the Citation for Serious Violation and is whether the trim saws operated by Respondent were \u2018hand-fed crosscut table saws\u2019 within the contemplation of 29 CFR 1910.213(d)(1). Here, as in the companion case of Consolidated Pine, Inc., Docket No. 945, we hold they were not.\t\t\t\t\t\t\t\t\t\tThe reason for this holding is that the trim saws were not \u2018hand-fed.\u2019 At best, this term is ambiguous and susceptible of more than one meaning under the facts of this\t\t\t\t\t\tparticular case. Construing it most strongly in favor of Respondent, therefore, results in a vacation of the Citation alleging the violation. Some discussion of at least the more important material facts would be useful in showing the reason for this holding.\t\t\t\t\t\t\t\t\t\tEight trim saws are alleged to be in violation of the standard in this case. One is at each end of a\t\t\t\t\t\tsixteen foot long\t\t\t\t\t\tgrading table, at the center of which stands the operator, or \u2018grader.\u2019 At this point the table is its narrowest width and from across it the grader lifts\t\t\t\t\t\tmoulding\t\t\t\t\t\tfrom a trough\u2014about twelve inches deep and of equal width\u2014in front of him and trims each piece on one or\t\t\t\t\t\tboth of the saws. Each saw is eight feet from the point in the center of the table exactly in front of the workman. The purpose of this operation is to remove knots, pitch pockets and other imperfections from the\t\t\t\t\t\tmoulding,\t\t\t\t\t\tand also\t\t\t\t\t\tto see it ends up in standard marketable lengths such as eight, ten, twelve, fourteen or sixteen feet, etc. Secretary\u2019s Exhibits 1 and 2 show either two such tables or one photographed twice.\t\t\t\t\t\t\t\t\t\tIn his testimony John Goodman, the Compliance Officer, stated that Secretary\u2019s Exhibit 2 shows the workman \u2018…..reaching across the top of the saw, on the lower end of the saw table,\t\t\t\t\t\twith his feet in the air . . .\u2019 (TR 13). Perhaps it should be noted in passing that Goodman\u2019s conclusion is impossible. The workman\u2019s right heel is off the floor, as possibly is his right toe. The outer aspect of his left thigh and left hip are upright and against a point almost exactly in the center of the\t\t\t\t\t\tsixteen foot\t\t\t\t\t\ttable; which is said to be thirty-six inches high but looks higher. From this position neither Wilt Chamberlain nor Kareem Jabbar could come within two feet of reaching the saw at the other end of the table with his fingertips.\t\t\t\t\t\t\t\t\t\tEach of the radial trim saws is about twelve inches in diameter and a little less than half the blade extends above the\t\t\t\t\t\ttable top. The blade is circled by a guard except for the center of the top portion where there is an opening of approximately six inches for trimming the\t\t\t\t\t\tmoulding. The guards appear to be several inches in width. That portion not immediately around the blade extends toward the center of the table.\t\t\t\t\t\t\t\t\t\tThe testimony varies somewhat as to the distance of the workman\u2014or his hand\u2014from either of the saws while performing his duties. As in the Consolidated Pine case, John Goodman, the Compliance Officer, testified the hazard involved with the saws was not to the workmen using them, but to one who might be passing by. Although there is some testimony the operator might be four or five feet from a saw while performing his duties, it is reasonable to find there would be no reason for his hand to be closer than five feet from either saw in the normal course of the grader\u2019s work.\t\t\t\t\t\t\t\t\t\tPrineville\t\t\t\t\t\tMouldings, Inc. had operated a\t\t\t\t\t\tmoulding\t\t\t\t\t\tplant at Prineville, Oregon four or five years at the time of the inspection in May of 1972. It employed twenty-six to twenty-eight people manufacturing lineal pine\t\t\t\t\t\tmoulding.\t\t\t\t\t\t\t\t\t\tAs is true of all other\t\t\t\t\t\tmoulding\t\t\t\t\t\tmanufacturing operations in the region (the managers of two others testified in this case) the type of saw used by Respondent is the only one used for the\t\t\t\t\t\tparticular operation\t\t\t\t\t\tdescribed in trimming\t\t\t\t\t\tmoulding. The three plant managers with experience of thirty, twenty and twenty years respectively knew of no other method used in the lumber industry anywhere to trim lineal\t\t\t\t\t\tmoulding; except in small operations where speed of operation is not important.\t\t\t\t\t\t\t\t\t\tPrineville\t\t\t\t\t\tMouldings, as have\t\t\t\t\t\ta number of\t\t\t\t\t\tother operators, has tried various types of guards for the trim saws. Their experiments have gone farther than, for example, those of Consolidated Pine.\t\t\t\t\t\t\t\t\t\tUsing a guard which complied with the standard they are charged with violating, with the blade of the trim saws completely covered, one\t\t\t\t\t\tmoulding\t\t\t\t\t\tmachine operated for several shifts to determine the effect on production. It was reduced from an average of about 8,000 lineal feet per shift to 6,000 lineal feet per shift. This decrease in production, along with other factors such as a large amount of damaged and wasted\t\t\t\t\t\tmoulding, made this operation economically impossible.\t\t\t\t\t\t\t\t\t\tRespondent had also constructed a guard for the grading tables and trim saws which was in use at the time of the hearing. It was not described in detail but was stated to be made of welded rebar made into a \u2018cage\u2019 around the table and saws in such a manner it would be impossible for anyone to\t\t\t\t\t\tcome in contact with\t\t\t\t\t\tthe offending saws.\t\t\t\t\t\t\t\t\t\tEugene Moorman is manager of Respondent. It was his opinion\u2014shared by the others\u2014that the standard in question does not apply to the trim saws Respondent uses. Referring to the Federal Register handed him and containing the standard, he testified:\t\t\t\t\t\t\t\t\t\tQ. Had you read those before?\t\t\t\t\t\t\t\t\t\tA. Yes, I read them, but I couldn\u2019t comprehend.\t\t\t\t\t\t\t\t\t\tQ When you read them, did you believe that they applied to trim saws?\t\t\t\t\t\t\t\t\t\tA. No.\t\t\t\t\t\t\t\t\t\tQ Why not?\t\t\t\t\t\t\t\t\t\tA Well, when I read that one, it applied to a table saw or a hand-fed table saw, which is\u2014well, you feed it by hand, directly into the saw. (TR 75)\t\t\t\t\t\t\t\t\t\t\u00a0\t\t\t\t\t\t\t\t\t\tAt another point in his testimony is the following on Cross Examination:\t\t\t\t\t\t\t\t\t\tQ. The word \u2018trim\u2019, that is kind of a local word, isn\u2019t it, sir?\t\t\t\t\t\t\t\t\t\tA. Well, it\u2019s not a local word. It\u2019s throughout the industry.\t\t\t\t\t\t\t\t\t\tQ. I understand, but it just trims the material?\t\t\t\t\t\t\t\t\t\tA. That\u2019s right.\t\t\t\t\t\t\t\t\t\tQ. Now, with reference\u2014when you\t\t\t\t\t\tsay\t\t\t\t\t\t\u2018throughout the industry\u2019, by the way, you meant the\t\t\t\t\t\tmoulding\t\t\t\t\t\tindustry?\t\t\t\t\t\t\t\t\t\tA. Right. The lumber industry.\t\t\t\t\t\t\t\t\t\tQ. Pardon me?\t\t\t\t\t\t\t\t\t\tA. It\u2019s a term used throughout the lumber industry.\t\t\t\t\t\t\t\t\t\tQ. Anything that trims materials is a trim saw?\t\t\t\t\t\t\t\t\t\tA. Right.\t\t\t\t\t\t\t\t\t\tQ. It is not a manufacturer\u2019s term; it is not a special term that has any meaning, it just does a function of trimming, correct?\t\t\t\t\t\t\t\t\t\tA. When you\u2014if you specified\u2014if you ordered a saw, for example, and you\u2014I don\u2019t care what manufacturer you ordered it from and you ordered a trim saw, this is what he would specify which type trim saw. He wouldn\u2019t say \u2018Well\u2019\u2014he would know immediately you need a trim saw. All you have to do is specify which\t\t\t\t\t\ttype\t\t\t\t\t\ttrim saw. (TR 84)\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\tOn pages 93 and 94 of the\t\t\t\t\t\ttranscript\t\t\t\t\t\tmay be found a reasonably knowledgeable explanation of a \u2018hand-fed\u2019 saw by Mr. Moorman.\t\t\t\t\t\t\t\t\t\tQ. When you were first reading it and even up until today, did you regard that trim saw as a hand-fed saw?\t\t\t\t\t\t\t\t\t\tA. No, not really.\t\t\t\t\t\t\t\t\t\tQ. Normally, to you, when you think of a hand-fed saw, what type of saw are you thinking of?\t\t\t\t\t\t\t\t\t\tA. I am thinking of a table saw, which is a saw that is used\u2014it is on a table, maybe 4 feet square.\t\t\t\t\t\t\t\t\t\tQ. Where you\t\t\t\t\t\tactually push\t\t\t\t\t\tthe material into?\t\t\t\t\t\t\t\t\t\tA. The material is fed\t\t\t\t\t\tactually into\t\t\t\t\t\tthe saw by hand and into the saw itself by hand.\t\t\t\t\t\t\t\t\t\t\u00a0\t\t\t\t\t\t\t\t\t\tAgain\t\t\t\t\t\twe come to the problem of construing the language of the standard. If the trim saws of Respondent are contemplated by this language as \u2018hand-fed crosscut table saws\u2019 within the guarding requirements for \u2018woodworking machinery,\u2019 then they must be:\t\t\t\t\t\t\t\t\t\t1. woodworking machinery\t\t\t\t\t\t\t\t\t\t2. table saws\t\t\t\t\t\t\t\t\t\t3. crosscut saws\t\t\t\t\t\t\t\t\t\t4. circular saws\t\t\t\t\t\t\t\t\t\t5. hand-fed\t\t\t\t\t\t\t\t\t\tAs was stated above, the holding here is the standard does not contemplate the trim saws of Respondent because they are not hand-fed.\t\t\t\t\t\t\t\t\t\tThe language of the regulation will be construed most strongly in favor of one charged with a breach of a duty imposed by it\u2014in this case Respondent. A further reason for construing the language in this manner is the fact that the statute here involved is in derogation of common law and creates new duties on the part of employers, including Respondent.\t\t\t\t\t\tThus\t\t\t\t\t\tthe wording will be construed most strongly \u2018In favor of those against whom such statutes may be employed.\u2019 50 Am.\t\t\t\t\t\tJur. States., Sec. 402, p. 425. If there is an ambiguity as to the meaning of the word \u2018hand-fed\u2019 then the Secretary cannot prevail.\t\t\t\t\t\t\t\t\t\tWe should refer again to the uniform holding of all courts that unless a contrary intention appears from the context, words will be given their ordinary,\t\t\t\t\t\tevery day\t\t\t\t\t\taccepted meaning. The plain, simple, direct inference from the words \u2018hand-fed crosscut table saws\u2019 is that the hands of\t\t\t\t\t\tthe workmen are endangered and exposed to the saws\u2014and that the \u2018feeding\u2019 is direct control from\t\t\t\t\t\tclose proximity, in the immediate area.\t\t\t\t\t\t\t\t\t\tIt is within common knowledge that many types of saws, particularly in the woodworking industry, are fed directly by hand. Here the grader or trim saw operator has at least one hand on a length of newly formed\t\t\t\t\t\tmoulding\t\t\t\t\t\twhen its ends are trimmed by one or\t\t\t\t\t\tboth of the saws\t\t\t\t\t\tat the table where he works. He is not in the position of one feeding the material directly to the saw where the machine guard required is installed for his benefit. The workman operating a \u2018hand-fed\u2019 saw is within reach of\t\t\t\t\t\tit, and\t\t\t\t\t\tis in immediate and direct danger of injury from the hazard the guard seeks to eliminate.\t\t\t\t\t\t\t\t\t\tAnother basis might be assigned for this holding, although it need not be. It might be argued that there is involved here a technical or specialized field of knowledge\u2014the lumber\u2014or perhaps the\t\t\t\t\t\tmoulding\t\t\t\t\t\tmanufacturing, industry. Applicable to it are certain safety standards, set in the same framework of specialized knowledge. Then in context the words \u2018Hand-fed crosscut table saws\u2019 do not have their usual, ordinary, accepted meaning. Rather, they have a meaning within the specialized field of knowledge.\t\t\t\t\t\t\t\t\t\tIf this be so, then opinion evidence is proper to aid the trier of the fact (Rule 702, Federal Rules of Evidence). Eugene Moorman qualified quite adequately as an expert in the field. His opinion is that Respondent\u2019s trim saws are not \u2018Hand-fed crosscut table saws\u2019 covered by the standard.\t\t\t\t\t\t\t\t\t\tHis opinion is clear, complete, reasonable; and is accepted. And there is no evidence to the contrary.\t\t\t\t\t\t\t\t\t\tIt should be noted here\u2014as in the\t\t\t\t\t\tConsolidated Pine\t\t\t\t\t\tcase\u2014that this is not a holding that the trim saws were adequately guarded. It is not a holding that persons passing the trim saws were not exposed to some danger from them. It is a holding that the standard Respondent is charged with violating does not contemplate the trim saws Respondent operated.\t\t\t\t\t\t\t\t\t\tAlthough it is in no way responsible for this holding, it is interesting to note that if a contrary result had been reached, it would then be necessary to decide whether the Secretary violated his statutory duty. A \u2018national consensus standard\u2019 was adopted, with mandatory application to all machinery defined therein, when the ANSI woodworking machinery standard stated at its beginning:\t\t\t\t\t\t\t\t\t\tNote: It is recognized that the standards for saw guards in 4.1 are not perfectly applicable to all operations for which saws are used. The standards given are those which woodworkers have agreed are most generally useful. Since there are a considerable number of cases not satisfactorily met by these standards, the enforcing authority should exercise rather wide latitude in allowing the use of other devices which give promise of affording adequate protection. It may be expected that by so doing further progress in saw guarding will be encouraged.\t\t\t\t\t\t\t\t\t\tThe precautions of limited applicability were not adopted by the Secretary. It is conceivable that because of statutory language he could not adopt them.\t\t\t\t\t\t\t\t\t\tMany interesting questions \u2018leap out\u2019 of the quoted language without study. Did this precautionary and limiting head note\t\t\t\t\t\tactually defeat\t\t\t\t\t\tany claim the ANSI standard had to being a \u2018national consensus standard?\u2019 Did the Secretary exceed his statutory duty in adopting the standard as a \u2018national consensus standard?\u2019 Did he have a right to limit its application as did the people who complied it? If he had such a right, what is the effect of his failing to do so? Is the standard void as adopted?\t\t\t\t\t\t\t\t\t\tThese are more interesting questions than those faced in the actual decision of the case. It is unfortunate they are moot.\t\t\t\t\t\t\t\t\t\tDisposition must be made of the two items constituting alleged non-serious violations. As to Item 2, although there is testimony of the necessity of leaving the covers off the holes in question to prevent the piling up of scrap wood, this is minimized considerably by the fact that other testimony shows that all violations charged except for the guarding of the trim saws had been corrected before the hearing. Whatever the difficulty may have been it was removed. A preponderance of the evidence shows the violation was proved.\t\t\t\t\t\t\t\t\t\tItem 6 presents a more difficult problem, but only because of the complexity of studying the requirements of 29 CFR 1910.219. It is sufficient to say that a careful review of the evidence fails to reveal sufficient proof to show a violation of any of the multiple provisions regarding guarding requirements for mechanical power transmission apparatus. The evidence lacks sufficient particularity and detail as to each belt, pulley, gear, chain drive and the flywheel. This item of the Citation must therefore be vacated along with its proposed penalty.\t\t\t\t\t\t\t\t\t\tBased upon a review of the entire record, the undersigned makes the following.\t\t\t\t\t\t\t\t\t\tFINDINGS OF FACT\t\t\t\t\t\t\t\t\t\tI\t\t\t\t\t\t\t\t\t\tPrineville\t\t\t\t\t\tMouldings, Inc. on all dates mentioned operated a lineal pine\t\t\t\t\t\tmoulding\t\t\t\t\t\tmanufacturing plant at Prineville, Oregon employing twenty-six to twenty-eight people. It had been in this business in this location four to five years when it was inspected on May 17, 1972 by a representative of the Secretary acting under Section 8 of the Occupational Safety and Health Act of 1970, supra. This inspection resulted in the issuance June 12, 1972 of Citations on which there are contests on a Citation for Serious Violation in the operation of trim saws in Respondent\u2019s plant, and Citation, Item 2, for failure to guard a floor opening and Item 6, for failure to guard mechanical power transmission apparatus.\t\t\t\t\t\t\t\t\t\tII\t\t\t\t\t\t\t\t\t\tAfter notice of contest as to these items, issues were joined by Complaint and Answer and the case was heard in Prineville, Oregon on September 7, 1972. There was full compliance with all procedural rules with respect to notice to prospective additional parties and none appeared.\t\t\t\t\t\t\t\t\t\tIII\t\t\t\t\t\t\t\t\t\tOn May 17, 1972, Respondent at its plant at Prineville, Oregon did not operate hand-fed crosscut table saws.\t\t\t\t\t\t\t\t\t\tIV\t\t\t\t\t\t\t\t\t\tOn May 17, 1972, Respondent left off covers from floor openings leading to its conveyor, which in turn led to the chipper, in violation of 29 CFR 1910.23(a)(5). Twenty-five dollars is a reasonable penalty for this violation.\t\t\t\t\t\t\t\t\t\tV\t\t\t\t\t\t\t\t\t\tThe Secretary failed to prove by a preponderance of the evidence that on the date alleged Respondent was in violation of 29 CFR 1910.213(a)(9) in failing to guard mechanical power transmission apparatus.\t\t\t\t\t\t\t\t\t\tBased upon the foregoing findings and upon all facts admitted, stipulated or proved by uncontroverted substantial credible relevant evidence, the undersigned makes the following\t\t\t\t\t\t\t\t\t\tCONCLUSIONS OF LAW\t\t\t\t\t\t\t\t\t\tI\t\t\t\t\t\t\t\t\t\tOn the dates alleged and named in the foregoing Findings of Fact, the Respondent was not in violation of 29 CFR 1910.213(a)(1) for failing to guard hand-fed crosscut table saws within the contemplation of the standard in question. Respondent is entitled to an order\t\t\t\t\t\tdismissing the Complaint as to this alleged violation and vacating the Citation and proposed penalty.\t\t\t\t\t\t\t\t\t\tII\t\t\t\t\t\t\t\t\t\tOn the date alleged and mentioned in the foregoing findings, Respondent was in violation of 29 CFR 1910.23(a)(5) for failure to guard floor openings by leaving the covers thereof off the openings leading to a conveyor, which in turn led to the chipper at the plant. Twenty-five dollars should be assessed for this violation.\t\t\t\t\t\t\t\t\t\tIII\t\t\t\t\t\t\t\t\t\tOn the date alleged, Respondent was not in violation of 29 CFR 1910.213(a)(9) for failure to provide guards required for mechanical power transmission apparatus to any woodworking machinery it maintained at its Prineville, Oregon plant. Respondent is entitled to an order dismissing the Complaint as to this item of the Citation and vacating the Citation and proposed penalty.\t\t\t\t\t\t\t\t\t\tORDER\t\t\t\t\t\t\t\t\t\tBased upon the foregoing, it is hereby ORDERED\t\t\t\t\t\t\t\t\t\tI\t\t\t\t\t\t\t\t\t\tThe Citation for Serious Violation issued by the Secretary June 12, 1972 naming the Respondent therein and alleging a violation of 29 CFR 1910.213(d)(1) for failure to guard hand-fed crosscut table saws be and the same hereby is vacated. The proposed penalty in the amount of $550.00 in connection with this Citation is likewise vacated. The allegations of the Complaint of the Secretary alleging this violation are dismissed.\t\t\t\t\t\t\t\t\t\tII\t\t\t\t\t\t\t\t\t\tAs to the allegations of the Citation issued by the Secretary June 12, 1972 naming therein the Respondent and its operation of a\t\t\t\t\t\tmoulding\t\t\t\t\t\tplant at Prineville, Oregon, the following disposition is made:\t\t\t\t\t\t\t\t\t\t(a) Item 2 of the Citation alleging a violation of 29 CFR 1910.23(a)(5) for failing to guard a floor opening by leaving a cover off the opening is affirmed and the proposed penalty in the amount of $25.00 is affirmed.\t\t\t\t\t\t\t\t\t\t(b) Item 6 alleging a violation of 29 CFR 1910.213(a)(9) for failing to guard woodworking machinery of Respondent in the manner required for guarding of mechanical\t\t\t\t\t\tpower transmission apparatus be and the same hereby is vacated. The proposed penalty in the amount of $65.00\u2014amended by the proof to $55.00\u2014be and the same hereby is vacated.\t\t\t\t\t\t\” \t\t\t\t\t\t\t\t\t\u00a0\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\u00a0\t\t\t”
