Pressure Sensitive Push Body Bar - Barrier Guard and Estop

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(a)(3)(iv)(i) lists forming rolls and calenders as machines that usually require point-of-operation guarding. These rotating equipment types create severe in-running nip points that can pull in clothing, hair, or body parts, requiring fixed or adjustable guards and emergency stops.

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.

B11.12 specifies safety requirements for the design, construction, operation, and maintenance of roll-forming and roll-bending machines, helping reduce hazards in these high-speed metal-shaping processes.

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.

B11.17 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.
