Each table circular saw shall be protected by a hood complying with all the requirements of point (c)(1) of this section for circular saw hoods. Two-blade rotating saws shall be fully protected in accordance with all regulations applicable to circular transverse saws or all requirements applicable to circular saws, depending on the type of saw mounted on the mandrels. There are 29 OSHA-approved state plans that implement national occupational health and safety programs. Government plans must include standards and enforcement programs that are at least as effective as OSHA`s and may have different or more stringent requirements. All belts, pulleys, gears, shafts and moving parts must be protected in accordance with the special requirements of ยง 1910.219. It is recommended to equip each motorized woodworking machine with a circuit breaker that can be locked in the off position. This checklist includes regulations published by the United States. Department of Labor, Occupational Safety and Health Administration (OSHA) under General Industry Standard 29 CFR 1910.213 and Construction Standard 29 CFR 1926.304. It applies to all woodworking machines. This checklist should be used in conjunction with the checklist of general requirements for machinery. The above provisions apply only to private employers and their employees, unless they have been enacted by a public authority and apply to other categories such as public sector employees. An affirmative answer to a question means that that part of the inspection complies with OSHA and EPA standards or a non-regulatory recommendation.
Bold definitions of terms can be found at the end of the checklist. Swivel saws. The requirements of this paragraph shall also apply to table-mounted chainsaws. All knives and cutting heads of woodworking machines must be sharp, fitted properly and securely attached. If two or more knives are used in a head, they must be properly balanced. The reference to certain machines in points (a) to (q) and in this paragraph (r) of this Section is not intended to exclude other woodworking machines from the obligation to install appropriate guards and extractor hoods in order to minimise the risks caused by the point of operation of such machinery. Woodworking risks are addressed in OSHA standards for the industry in general. This section presents OSHA standards and documents related to woodworking.
Woodworking can be very dangerous, especially if workers use the machinery improperly or without proper safety precautions. Violations of Occupational Safety and Health Administration (OSHA) Standards 1910.212(a)(1) and 1910.212(a)(3)(ii) have recently topped the list of citations issued during OSHA inspections. Poorly or poorly protected woodworking machines can lead to the following injuries: lacerations, amputations, severed fingers and blindness. Wood dust and the chemicals used to finish products pose a health risk to woodworkers and can cause skin and respiratory illness. Inspection and maintenance of woodworking machines. To create a safe and healthy workplace, this electronic tool* describes the main hazards and possible solutions for woodworking. This electronic tool does not replace OSHA woodworking standards, but can help clarify the regulatory language and technical information covered by these standards. “shall” and “shall” are used in this eTool to indicate when a calculator or other security measure is required by OSHA; “should” is used to indicate recommended safe work practices. For more information, see General Industry Standards, 29 CFR, Part 1910. OSHA-specific standards for woodworking are also listed in the Additional References section of this electronic tool.
Electronic tools are “stand-alone”, interactive, web-based training tools on topics related to occupational safety and health. They are highly illustrated and use graphic menus. As stated in the disclaimer, electronic tools do not create new OSHA requirements. In the case of combination or universal woodworking machines, each point of application of a tool must be protected in a separate machine as required for such a tool. Emphasis is placed on the importance of maintaining the cleanliness of woodworking machines, especially with regard to the effective operation of guards and the prevention of fire risks in switch boxes, bearings and motors. Frames and all exposed non-living metal parts of portable wood-fired electrical machines operating at more than 90 volts from earth must be grounded, and other portable motors that drive hand-held power tools during operation must be grounded when operating at more than 90 volts from the ground. Grounding should be done using a separate grounding cable and a polarized plug and socket. The feed rollers of self-demonstrated grinding machines must be protected by a semi-cylindrical guard to prevent the operator`s hands from coming into contact with the incoming rollers at any point. The protector must be made of heavy material, preferably metal, and securely attached to the frame on which the rollers are supported so that it remains suitable for any thickness of the shaft.
The bottom of the guard must be within three-eighths of an inch of a plane formed by the bottom or contact surface of the feed roller where it touches the shaft. The cutting effect of the blade can throw away broken wood chips, chips and saw teeth. The saw, cutting head or tool collar shall not be placed or mounted on a machine arbor unless the tool has been precisely machined to size and shape to fit the mandrels. When an exhaust system is used, the protection system shall be part or the whole of the hood and shall be made of metal the thickness of which is at least equal to that referred to in paragraph 3 of this paragraph. Each drum grinding machine shall be fitted with an extractor hood or, if no exhaust system is required, with another protective device arranged so as to surround the rotating drum, except for that part of the roller above the table where a table is used which may be necessary and suitable for the application of the material to be refined. The cutting heads of towers for turns, whether rotating or not, shall be covered as completely as possible with caps or shields. If necessary, use a filler between the fence and the saw blade, for example, if there is a short distance to the side of the fence. Feed rollers and saws must be protected by a fume hood or guard to prevent the operator`s hands from coming into contact with the incoming rollers at any point. The guard must be made of heavy material, preferably metal, and the bottom of the guard must be within three-eighths of an inch of the plane formed by the bottom or work surfaces of the feed rollers. This distance (three-eighths of an inch) can be increased to three-quarters of an inch if the front edge of the cover in front of the pinch point between the front coil and the movement is extended to at least 5 1/2 inches. At the rear ends of the frames over which the power belts pass, the sprockets and chains must be protected on the sides by plates protruding from the perimeter of the sprockets and the ends of the horns.
Each circular saw (except automatic saws with a roller or wheel at the back of the saw) must be equipped with a spreader securely attached behind the saw. The spreader should be slightly thinner than the saw joint and slightly thicker than the saw disc. Installation should be carried out in such a way that the front end of the unit is slightly higher than the rear end, so that the cutting head gently returns to the starting position when released by the operator. The feed rollers of roller glue spreaders must be protected by semi-cylindrical protection. The bottom of the guard must be within three-eighths of an inch of a plane formed by the bottom or contact surface of the feed roller where it touches the shaft. Automatic chainsaws that are hoisted continuously without the operator being able to control each stroke should not be used. If the counterweight does not surround the rod, a safety chain must be attached to it; Each portable circular saw must be equipped with non-retractable fingers or dogs arranged to counteract the thrust or tendency of the saw to pick up the material or return it to the operator. They must be designed in such a way as to provide sufficient retention capacity for all thicknesses of the materials to be cut. Each band saw must be equipped with a tension control device indicating adequate tension for standard saws used on the machine to help eliminate saw breaks due to incorrect tension.
Where two or more workers are employed simultaneously on the same two-handed motorized plating cutter, the device must be so arranged that each worker simultaneously uses both hands on the controls to start the cutting movement and at least one hand on an actuation to complete the cutting. Subject: 29 CFR 1910.213(a)(4), Requirements for Woodworking Machines The insertion of wedges between the saw disc and the collar to form a so-called “oscillating saw” is not permitted. Each machine must be designed to be free from appreciable vibration when the largest tool is mounted and to operate at full speed at idle.
