This checklist covers regulations issued by the U.S. Department of Labor, Occupational Safety and Health Administration (OSHA) under the general industry standard 29 CFR 1910.213. It applies to the following: jointers; tenoning machines, boring and mortising machines; wood shapers and similar equipment; planing, molding, sticking, and matching machines; profile and swing-head lathes and wood-heel turning machines; sanding machines; veneer cutters and wringers; and miscellaneous woodworking machines. This checklist must be used in conjunction with the Woodworking Machinery General Requirements checklist. The regulations cited apply only to private employers and their employees, unless adopted by a State agency and applied to other groups such as public employees. A yes answer to a question indicates that this portion of the inspection complies with the OSHA or EPA standard, or with a nonregulatory recommendation.

- Other types of counterweights are suspended by chain or wire rope and shall travel in a pipe (or other suitable enclosure) if they might fall and cause injury.
- Are universal joints on spindles of boring machines completely enclosed to prevent contact by the operator? [29 CFR 1910.213(l)(5)]
- Is each operating treadle covered by an inverted U-shaped metal guard, fastened to the floor, and of adequate size to prevent tripping? [29 CFR 1910.213(l)(6)]
Wood Shapers and Similar Equipment
- Is the cutting head of each wood shaper or hand-fed panel raiser (or other similar machine that is not automatically fed) enclosed with a cage or adjustable guard designed to keep the operator’s hand away from the cutting edge? [29 CFR 1910.213(m)(1)]
- Planing, Molding, Sticking, and Matching Machines Is each planing, molding, sticking, and matching machine equipped with a metal guard covering the cutting heads? [29 CFR 1910.213(n)(1)]
- When an exhaust system is used, does the guard form part of the exhaust hood? [29 CFR 1910.213(n)(2)]Note: If the guard is constructed of sheet metal, the material used shall be at least 1/16 inch thick, and if it is constructed of cast iron, it must be at least 3/16 inch thick.
