Machine Safeguarding

Upon completing this program, participants will be able to:

• Identify hazardous machine motions: rotating (shafts, couplings, spindles, chucks, flywheels, gears), reciprocating (rams, slides, platens), and transversing (feed mechanisms, tables, carriages), and the injury mechanisms each creates (entanglement, nip point, impact, shear).
• Identify hazardous machine actions: cutting (saws, drills, milling, turning), punching (punch presses, stamping), shearing (hydraulic and mechanical shears), bending (press brakes, roll formers), and the point-of-operation hazards specific to each action.
• Select appropriate guard types: fixed guards (permanent, no adjustment, preferred when feasible), interlocked guards (machine stops when guard opens), adjustable guards (operator adjusts for workpiece size), self-adjusting guards (guard moves with stock), and the selection criteria based on machine type, operation, and operator interaction.
• Apply safeguarding devices: light curtains (optical presence-sensing), safety mats (pressure-sensing floor areas), area scanners, two-hand control devices (requires both hands away from danger zone), two-hand trip devices, restraint devices, pullback devices, and gates (Type A and B).
• Evaluate guard construction: guard material (metal, polycarbonate, wire mesh), attachment method (fasteners requiring tools for removal), opening size (OSHA Table O-10 maximum opening versus distance from hazard), structural adequacy, and the construction that prevents guards from becoming hazards themselves.
• Apply machine-specific safeguarding standards: woodworking machines (§1910.213), abrasive wheel machinery (§1910.215), mechanical power presses (§1910.217), and mechanical power transmission apparatus (§1910.219 — shafts, pulleys, belts, chains, gears, couplings, flywheels).
