Machine Guarding — General Requirements (29 CFR 1910.212)
Machine guarding violations address the requirement to protect workers from hazards created by point of operation, ingoing nip points, rotating parts, and flying chips. Guards must prevent employee contact with dangerous machine components.
What 29 CFR 1910.212 Requires
Machine guarding under Subpart O is a general industry standard that applies to construction sites wherever fixed machinery is in use. Table saws, bench grinders, drill presses, and other equipment must have guards that prevent worker contact with moving parts, flying debris, and point-of-operation hazards:
- Guards required at point of operation where employee exposure exists
- Guards must prevent workers from reaching into the danger zone
- Guards must be affixed to the machine where possible and secured
- Guards must not create additional hazards (sharp edges, pinch points)
- Machine anchoring required to prevent walking or movement during operation
- Barrel, container, and drum guarding requirements for specific operations
Most Common Violations
Machine guarding violations are among the most visible citations — a missing guard is immediately apparent during a walkaround. The most problematic pattern is guards that were intentionally removed by workers to speed up operations. Evidence of tampering significantly increases penalty severity:
- Missing or removed machine guards at point of operation
- Guards that do not fully protect the danger zone
- Guards removed for maintenance and not replaced before operation
- No training on machine guarding requirements
- Machines not anchored to prevent movement during operation
- Improvised guards that do not meet OSHA specifications
Penalty Exposure
Penalty range: $1,190–$16,550 per serious violation; up to $165,514 per willful violation
Machine guarding citations are almost always classified as serious because the hazard — amputation, laceration, or crushing — is immediate. Penalties can reach $16,550 per serious violation in 2026. If inspectors find evidence that guards were deliberately removed, the violation may be classified as willful at $165,514.
Equipment inspection records and training documentation showing that guards are regularly checked and workers are trained not to remove them provide the strongest defense against elevated classifications.
Documentation You Need
Machine guarding documentation focuses on equipment-specific hazard assessments, regular inspections, and operator training. The goal is to demonstrate a systematic approach to guard maintenance:
- Machine hazard assessment for each piece of equipment
- Guard inspection and maintenance records
- Training records on machine guarding and safe operation
- Corrective action logs when guards are found missing or inadequate
- Machine-specific operating procedures
- Equipment maintenance and guard replacement schedules
What Inspectors Look For
During an OSHA inspection, machine guards are checked visually during the walkaround. Missing guards are photographed immediately. Inspectors then look for evidence of whether the condition is systemic or isolated:
- Guards in place at every point of operation — first visual check
- Guard effectiveness — does it actually prevent contact with the danger zone?
- Guard condition — securely attached, no modifications or bypasses
- Training records for machine operators
- Maintenance logs showing guards are inspected regularly
- Evidence of guard removal and replacement procedures
