Machine Guarding — General Requirements (29 CFR 1910.212)
Machine guarding violations under 29 CFR 1910.212 require guards on machinery to protect workers from rotating parts, flying chips, and sparks. This general industry standard applies to construction sites where fixed machinery such as table saws, grinders, and drill presses are in use.
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:
- One or more methods of machine guarding must protect workers from hazards created by point of operation, ingoing nip points, rotating parts, and flying debris
- Guards must be affixed to the machine where possible and secured to prevent tampering
- Point-of-operation guards required on machines whose operation exposes workers to injury
- Anchoring fixed machinery required to prevent walking or movement during operation
- Guarding must not create additional hazards (sharp edges, pinch points from the guard itself)
- Barrel, container, and drum guarding must prevent worker contact with rotating parts
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 guards on table saws, bench grinders, or drill presses
- Guards that do not fully cover the point of operation or moving parts
- Workers bypassing or disabling machine guards to speed up operations
- No guard on abrasive wheel machinery (grinders) exposing the wheel beyond allowable limits
- Fixed machinery not properly anchored to prevent movement during operation
- Guards with sharp edges or gaps that create new pinch point hazards
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 guarding hazard assessment for all machinery on site
- Equipment inspection records documenting guard presence and condition
- Training records for operators on machine guarding requirements and proper use
- Maintenance records showing guards were replaced or repaired after damage
- Corrective action records when guards are found missing or defective
- Manufacturer specifications for required guards on each piece of equipment
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 on all machinery — missing guards are immediately visible during walkaround
- Point-of-operation exposure — can a worker reach into the danger zone?
- Evidence that guards were removed or bypassed (tool marks, zip ties, wedges)
- Training records for every worker operating guarded machinery
- Inspection records showing systematic guard checks
- Manufacturer guard specifications versus what is actually installed
