2 Hand Control Safety System

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.

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.

B11.1 provides the industry consensus safety requirements for mechanical power presses, including design, guarding, control systems, modification, risk assessment, and safe operation of these machines.

B11.15 specifies safety requirements for power-driven machines designed to bend bar, pipe, tube and shapes—including design, guarding, installation, operation and lifecycle responsibilities.

B11.16 defines safety requirements for powder-metal compacting presses, covering mechanical, hydraulic, or direct-drive machines used to compress metallic or non-metallic powders into parts. It sets roles for manufacturers and users to reduce risk of crush, ejection, and contact hazards in powder metallurgy operations.

B11.17 outlines safety requirements for horizontal hydraulic extrusion presses — machines that extrude metal billets horizontally under high pressure — covering design, guarding, control systems, modification and lifecycle responsibilities for safe operation.

B11.2 provides industry consensus safety requirements for hydraulic and pneumatic power presses—machines that transmit force via hydraulic or pneumatic systems to form, cut, or assemble materials—and outlines design, guarding, control and lifecycle responsibilities.

B11.20 sets safety requirements for integrated manufacturing systems, defining how linked machines, material handling, and control systems must be designed, installed, operated and maintained to reduce risks introduced by system-integration.

B11.3 provides safety requirements specifically for power press brakes — covering machine design, operation, guarding, control modes, and lifecycle responsibilities to protect operators from hazards in bending operations.

B11.4 sets consensus safety requirements for shears — machines with one fixed and one non-rotating moving blade used to cut material by shearing — covering design, guarding, operation, maintenance and life-cycle responsibilities.

B11.5 establishes safety requirements for ironworker machines (combined punching, shearing, notching and forming tools) covering their construction, care and use, including guarding, control, maintenance and lifecycle responsibilities.
