OSHA 1910.212(a) establishes the general machine guarding requirements that protect employees from points of operation, moving parts, in-running nip points, and flying debris. It forms the foundation for all other machine guarding rules.

OSHA 1910.212(a)(1) requires that one or more methods of machine guarding be provided to protect operators and nearby employees from rotating parts, flying chips, sparks, and other mechanical hazards. It defines the core duty to guard all dangerous machine motions.

OSHA 1910.212(a)(2) defines the construction and design requirements for machine guards, ensuring they are strong, secure, and effective in protecting workers from mechanical hazards without introducing new risks.

OSHA 1910.212(a)(3) requires that machines have point of operation guards to protect operators from contact with cutting, shaping, or forming actions. This rule ensures workers are shielded wherever material is fed into or removed from a machine.

OSHA 1910.212(a)(3)(ii) requires that the design and construction of machine guards prevent the operator from being exposed to injury during operation, setting a performance-based standard for guard effectiveness and safety.

OSHA 1910.212(a)(3)(iv) lists machine types that typically require point-of-operation guarding, including guillotine cutters, shears, alligator shears, power presses, milling machines, power saws, jointers, portable power tools, and forming rolls and calenders.

OSHA 1910.212(b) requires that machines designed for fixed location use be securely anchored to prevent movement or tipping. Anchoring is critical for stable operation and worker safety.

OSHA 1910.213(a)(1) requires all woodworking machines to be constructed and maintained free from noticeable vibration when the largest tool is mounted and operated at full speed. This ensures safe, stable operation and prevents mechanical failure or operator injury.

OSHA 1910.213(a)(11) requires all portable electric woodworking machines operating above 90 volts to ground to be properly grounded. Grounding must be provided through a separate ground wire and a polarized plug and receptacle to prevent electrical shock hazards.

OSHA 1910.215 sets forth comprehensive safety requirements for abrasive wheel machinery, including grinders, buffers, and cutoff machines. It mandates proper wheel guarding, tool rest adjustment, ring testing, and maintenance to prevent wheel breakage and operator injury.

OSHA 1910.215(a)(1) mandates that abrasive wheels be used only on machines equipped with properly designed safety guards. These guards must meet the requirements of this section, with limited exceptions for specific tools such as certain mounted or internal wheels.

OSHA 1910.215(a)(1)(i) provides an exception to the machine guarding rule for abrasive wheels used for internal grinding operations performed within the workpiece, where standard external wheel guards are not feasible or necessary.

OSHA 1910.215(a)(1)(ii) provides an exception to the abrasive wheel guarding requirement for mounted wheels 2 inches or smaller in diameter when used in portable operations, recognizing their low mass and limited hazard potential compared to larger wheels.

OSHA 1910.215(a)(1)(iii) provides a guarding exception for specific abrasive wheel types—cones, plugs, and threaded hole pot balls (Types 16, 17, 18, 18R, and 19)—when the workpiece itself provides adequate protection against wheel contact and debris.

OSHA 1910.215(a)(2) defines the design requirements for abrasive wheel safety guards. Guards must cover the spindle end, nut, and flange projections, remain properly aligned with the wheel, and be fastened with hardware stronger than the guard itself, except where specific exemptions apply.

OSHA 1926.304(g) sets safety requirements for radial saws in construction, including guarding, non-kickback devices, and automatic return to safe position. These rules protect workers from lacerations, kickbacks, and other saw-related hazards.

ANSI B11.0 outlines the foundational requirements for machinery safety, including terminology, risk assessment, and risk reduction principles. It serves as the broad “Type A” standard that supports machine-specific standards in the B11 series such as B11.19 and B11.C-type documents.

B11.9 defines safety requirements for stationary grinding machines—covering machine design, guarding, control functions, operator access, and lifecycle responsibilities to reduce risk of injury from grinding operations.
