Machine Guarding & Safety Device Inspection Checklist [FREE PDF]

Machine guarding inspections are mandated under OSHA 29 CFR 1910.212, which requires that one or more methods of machine guarding be provided to protect operators and other employees from hazards such as those created by point of operation, ingoing nip points, rotating parts, flying chips, and sparks. ANSI B11 standards further define performance requirements for safeguarding systems across specific machine types. Regular documented inspections are essential to demonstrate due diligence, maintai

Industry: Manufacturing
Frequency: Weekly
Estimated Time: 30-45 minutes
Role: Maintenance Technician
Total Items: 38
Compliance: OSHA 29 CFR 1910.212 - Machine Guarding, OSHA 29 CFR 1910.147 - Control of Hazardous Energy (LOTO), ANSI B11.0-2020 - Safety of Machinery General Requirements, NFPA 70E-2021 - Standard for Electrical Safety in the Workplace, SMRP Best Practice 5.4 - Equipment Reliability and Maintenance

Fixed Guard Integrity

Assess the condition, positioning, and secure attachment of all fixed physical guards on the machine.

Are all fixed guards present and fully installed at every identified hazard point?
Are fixed guards free from cracks, deformation, missing fasteners, or structural damage?
Are all guard fasteners (bolts, screws, pins) present, tightened, and tamper-resistant?
Do fixed guards prevent operator contact with the point of operation during normal operation?
Are guard openings (mesh, slots) within allowable size limits to prevent hand or finger entry?
Attach photo of fixed guard condition?

Interlocked & Movable Guard Systems

Verify that interlocked guards function correctly and interrupt machine operation when opened or removed.

Do all interlocked guards automatically stop or prevent machine motion when opened?
Is the interlocking mechanism (switch, sensor, cam) free from damage, bypass, or defeat?
Does the machine fail to start when the interlocked guard is in the open position?
Is the guard reset/restart sequence correct, requiring deliberate operator action before restart?
Are interlock switches and wiring connections secure, labeled, and protected from environmental damage?

Lockout/Tagout (LOTO) Pre-Inspection Verification

Confirm LOTO procedures were followed before any guard removal or maintenance inspection activity on this equipment.

Was an authorized LOTO procedure applied before any guards were removed for inspection?
Is the equipment-specific LOTO procedure posted or readily accessible at the machine?
Were all energy isolating devices (electrical, pneumatic, hydraulic, gravity) identified and locked out?
Was zero-energy state verified (e.g., press button, check gauges) before inspection commenced?
Is the LOTO hardware (locks, hasps, tags) in serviceable condition and correctly applied?

Presence-Sensing Safety Devices

Inspect light curtains, two-hand controls, pressure-sensitive mats, and other electronic presence-sensing safeguards.

Are all light curtains, laser scanners, or area sensors clean, aligned, and operational?
Does the presence-sensing device reliably stop the machine when the detection zone is broken?
Is the safety distance (minimum distance from sensing field to hazard) correctly maintained?
Are two-hand control devices operational and requiring simultaneous actuation to cycle the machine?
Are safety mats or bumpers connected, free of damage, and triggering e-stop on activation?
Attach photo of presence-sensing device installation and condition?

Emergency Stop (E-Stop) & Safety Controls

Verify that emergency stop devices, safety relays, and machine control interlocks are correctly installed and functional.

Are emergency stop buttons present, clearly marked (red button/yellow background), and unobstructed?
Does each e-stop button immediately halt all machine motion when actuated?
Does the e-stop require a manual reset before the machine can restart?
Are pull-cord/rope e-stops (where installed) taut, functional along entire length, and labeled?
Are safety relays and safety PLCs in the control system operational and fault-indicating correctly?

Specific Hazard Guarding, Nip Points, Rotating Parts & Projections

Check guarding adequacy for rotating shafts, belts, gears, chains, nip points, and projecting machine parts.

Are all exposed rotating shafts, couplings, and spindles guarded with appropriate enclosures?
Are all belt, chain, and gear drives fully enclosed or guarded to prevent contact?
Are ingoing nip points on rollers, conveyors, and calendars adequately guarded?
Are projecting machine components (bolts, handles, keys) covered or eliminated to prevent strike hazards?
Are all chip, coolant, and debris deflectors in place to protect adjacent workers?

Deficiency Reporting & Corrective Action Tracking

Document any deficiencies identified, assign corrective actions, and record machine status at the end of inspection.

Were any guard deficiencies, damage, or missing safeguards identified during this inspection?
Describe all deficiencies found and their location on the machine?
Has a work order been created in the CMMS for each identified deficiency?
Is the machine safe to operate following this inspection, with all guards functional?
Overall machine guarding condition rating?
Additional comments or observations regarding machine guarding condition?
