Compliance guide
OSHA machine guarding requirements, in plain English.
Machine guarding is a perennial member of OSHA’s ten most-cited standards. The rule itself — 29 CFR 1910.212 — is two paragraphs long, and inspectors apply it to every machine on your floor. Here’s what it actually says, how it’s enforced, and how to audit your own shop before an inspector or insurance carrier does it for you.
What 1910.212 requires.
The general rule: one or more methods of machine guarding must protect the operator and other employees from hazards created at the point of operation, by ingoing nip points, rotating parts, and flying chips or sparks. If a machine can injure someone during normal operation, OSHA expects a guard, a device, or a safeguarding method between the person and the hazard.
Point of operation
Where the work actually happens — the press brake die, the saw blade, the drill chuck. If the operator’s hands can reach it during the cycle, it must be safeguarded. 1910.212(a)(1) and (a)(3)(ii) are the clauses inspectors cite most.
Guards must be attached to the machine
1910.212(a)(2): guards should be affixed to the machine itself where possible, and must not create hazards of their own — sharp edges, pinch points, or shear points.
Rotating parts, belts, and anchoring
Exposed shafts, belts, and pulleys under seven feet must be guarded (1910.219), fan blades under seven feet need guards with openings no larger than 1/2” (1910.212(a)(5)), and fixed machinery must be anchored so it can’t walk or tip (1910.212(b)) — one of the easiest citations to fix and one of the most common.
“Compliant” is behavioral, not a product label
OSHA doesn’t certify products. It describes what the machine must do with the safeguard in place. That’s why the fix is usually engineering — a guard sized to the machine — not a sticker.
Why shops act now
A single serious machine-guarding violation carries a five-figure penalty, and willful or repeat violations run ten times higher — before you count the workers’ comp claim, the insurance fallout, and the machine sitting red-tagged.
Which standard applies to which machine.
1910.212 is the catch-all, but several machine families have their own, more specific rules — and consensus standards (ANSI B11) that inspectors and insurers use as the benchmark for “feasible safeguarding.” The table is a starting point: confirm the standard against your specific machine and the current text at osha.gov.
| Machine | OSHA standard | Typical safeguarding |
|---|---|---|
| Press brakes | 1910.212 + ANSI B11.3 | Laser AOPD guarding (Lazer Safe), light curtains, two-hand control, rear access guarding |
| Mechanical power presses | 1910.217 | Light curtains, two-hand controls, barrier guarding, control reliability, brake monitoring, die safety blocks for in-die cavity work |
| Turret presses | 1910.212 (1910.217 if mechanically driven) | Pressure-sensitive safety matting, area laser scanners, light curtains, fencing |
| Roll forming lines | 1910.212 + ANSI B11.12 | Light curtains, barrier guarding, area laser scanners, interlocks |
| Abrasive wheels / grinders | 1910.215 | Wheel guards, adjusted work rests and tongue guards |
| Woodworking machinery | 1910.213 | Chip shielding, blade guards, anti-restart protection after power loss |
| Drill presses, lathes, mills, saws | 1910.212 general requirements | Chip shielding, chuck shields, custom point-of-operation guards, interlocks |
| Any machine | 1910.213(b) principle, NFPA 79 | Anti-restart (no-voltage release) controls, compliant emergency stop devices |
The quick self-audit checklist.
Walk the floor with this list. Every “no” is a gap an OSHA inspector or insurance auditor is likely to flag — and a fix that’s almost always cheaper than the citation. Use it as a starting point for your own hazard assessment: it isn’t exhaustive, and a formal risk assessment per ANSI B11.0 is the standard of care.
- Every machine's point of operation is barrier guarded, or a device (light curtain, laser AOPD, two-hand control) keeps hands out or controls access during the cycle.
- No exposed rotating shafts, couplings, belts, or pulleys below seven feet from the floor or working platform. (Lathe chucks are typically addressed with a chuck shield or chip shield rather than a full enclosure.)
- Guards are bolted to the machine with hardware that requires a tool to remove (no wing nuts) — not zip-tied, not leaning, not “usually on.”
- Removing or bypassing a guard requires a tool, and interlocked guards remove the hazard when opened.
- Machines that could injure on unexpected restart have anti-restart / no-voltage-release protection after a power loss.
- Grinders: chip shielding, work rests within 1/8” of the wheel, tongue guards within 1/4”.
- Press brakes: operators' hands never travel with the workpiece into the die cavity unprotected; guarding matches ANSI B11.3.
- In-die cavity work on presses uses die safety blocks rated for the slide or ram weight plus the heaviest upper die.
- Fixed machinery is anchored to prevent walking or tipping.
- Operators are trained on why each guard exists, and guard removal is treated as a disciplinary event, not a productivity hack.
- All safeguards and emergency stops are function tested on a regular basis — an e-stop or light curtain that was never wired in correctly looks exactly like one that works.
This guide summarizes federal OSHA general-industry requirements for awareness purposes. It isn’t legal advice and completing the checklist is no guarantee of compliance; state plans can be stricter, your specific machines and operations govern what applies, and a qualified safety professional should confirm your safeguarding.
