OSHA's general machine guarding standard, 29 CFR 1910.212, requires employers to protect operators and nearby workers from the hazards created by moving machine parts. It covers point of operation hazards, ingoing nip points, rotating parts, flying chips and sparks, and it applies to virtually every type of machine used in general industry.
Unguarded machinery can cause amputations, crushed fingers and hands, burns and blindness. Because 1910.212 is a general requirement rather than a machine-specific rule, OSHA can apply it to any machine that exposes workers to these hazards, which is one reason it appears on OSHA's top 10 list of most frequently cited standards.
What Is the Machine Guarding Standard?
29 CFR 1910.212, General requirements for all machines, sits in Subpart O of OSHA's general industry standards, Machinery and Machine Guarding. It is short, but it sets the baseline every machine must meet. Other sections in Subpart O add detailed rules for specific equipment:
- 1910.211, Definitions
- 1910.213, Woodworking machinery
- 1910.215, Abrasive wheel machinery
- 1910.216, Mills and calenders in the rubber and plastics industries
- 1910.217, Mechanical power presses
- 1910.218, Forging machines
- 1910.219, Mechanical power-transmission apparatus
Where a specific standard applies, it governs that machine. Where no specific standard exists, 1910.212 still requires effective guarding. OSHA lists the full set on its machine guarding standards page.
Key terms
- Point of operation: the area on a machine where work is actually performed on the material being processed, such as where a blade cuts or a die forms metal (1910.212(a)(3)(i)).
- Ingoing nip point: the point where two parts rotate toward each other, or a part rotates toward a fixed surface, and can draw in hands, hair or clothing.
- Guard: a barrier or device that prevents contact with a hazard. Common methods named in the standard include barrier guards, two-hand tripping devices and electronic safety devices.
Who Must Comply?
Every general industry employer whose employees operate or work near machinery must comply, regardless of size. That covers manufacturing, food processing, printing, woodworking, metal fabrication, recycling, warehousing with conveyors and balers, and maintenance shops. The standard protects both the operator and other employees in the machine area.
Construction, maritime and agriculture have their own machinery rules. States with OSHA-approved State Plans must have standards at least as effective as federal OSHA's and may be stricter, so check your state plan if you operate in one.
Key Requirements
Use one or more methods of guarding
Under 1910.212(a)(1), one or more methods of machine guarding must be provided to protect the operator and other employees from hazards such as those created by the point of operation, ingoing nip points, rotating parts, flying chips and sparks. The employer chooses the method, provided it is effective for the hazard.
General requirements for guards
Paragraph (a)(2) requires guards to be affixed to the machine where possible, and secured elsewhere if attachment to the machine is not possible for any reason. A guard must not create an accident hazard of its own. In practice, guards should be sturdy, hard to remove without tools and designed so workers cannot easily reach over, under, around or through them.
Point of operation guarding
Under (a)(3)(ii), points of operation that expose an employee to injury must be guarded. The guard must conform to any appropriate standard for that machine, and in the absence of one, it must be designed and built to prevent the operator from having any part of the body in the danger zone during the operating cycle.
Special hand tools for placing and removing material must let workers handle material without putting a hand in the danger zone. Under (a)(3)(iii), these tools supplement guarding. They do not replace it.
Paragraph (a)(3)(iv) lists machines that usually require point of operation guarding:
- Guillotine cutters, shears and alligator shears
- Power presses
- Milling machines
- Power saws and jointers
- Portable power tools
- Forming rolls and calenders
Revolving barrels, containers and drums
Under 1910.212(a)(4), revolving drums, barrels and containers must be guarded by an enclosure interlocked with the drive mechanism, so the barrel, drum or container cannot revolve unless the guard enclosure is in place.
Exposed fan blades
Under (a)(5), when the periphery of a fan's blades is less than 7 feet above the floor or working level, the blades must be guarded. The guard may not have openings larger than one-half inch.
Anchoring fixed machinery
Paragraph 1910.212(b) requires machines designed for a fixed location to be securely anchored to prevent walking or moving.
Inspection, Training and Documentation
1910.212 does not set an inspection frequency, a training curriculum or a recordkeeping requirement. Some machine-specific standards in Subpart O add their own inspection, training or record requirements, so check the specific section for each machine type you operate.
Even where the rule is silent, documentation is how you prove guards are in place and effective. Practical records include:
- A machine inventory showing each machine, its hazards and the guarding method used
- Periodic guarding inspections or audit checklists with findings and corrections
- Operator training on how guards work, why they must stay in place and who may adjust them
- Records of guard modifications, removals for maintenance and reinstallation
Guard removal for servicing is controlled by a separate rule. When servicing requires removing or bypassing a guard, or placing part of the body in the point of operation, the lockout/tagout standard generally applies.
Common Violations and Penalties
Machine guarding (1910.212) ranked tenth on OSHA's preliminary list of most frequently cited standards for fiscal year 2026. Common problems include:
- Missing point of operation guards on saws, presses, shears and similar machines
- Guards removed and never replaced after maintenance or a jam
- Bypassed interlocks or light curtains, often to speed up production
- Exposed rotating parts such as shafts, couplings, chains and sprockets
- Unguarded fan blades under 7 feet above the floor or working level
- Machines not anchored that are designed for a fixed location
- Relying on push sticks or hand tools instead of a guard
OSHA posts current maximum penalties on its penalties page. For penalties assessed after January 15, 2026, the posted maximum is $16,550 per serious violation and $165,514 per willful or repeated violation. An amputation also triggers a severe injury report to OSHA, which can lead to an inspection.
How to Comply: Step by Step
- Inventory your machines. List every machine, including portable power tools, conveyors, fans and older equipment in storage areas.
- Identify the hazards on each machine. Look at the point of operation, nip points, rotating parts, reciprocating motion and flying chips or sparks. A job hazard analysis for each task helps.
- Check for machine-specific standards. Confirm whether 1910.213 through 1910.219 applies, and follow its more detailed requirements.
- Select effective guarding. Use the hierarchy of controls: fixed barrier guards first, then interlocked guards or presence-sensing devices, with hand tools only as a supplement.
- Anchor fixed machinery so it cannot walk or move.
- Train operators and maintenance staff. Explain each guard's purpose, the ban on removing or bypassing guards, and how to report missing or damaged guards.
- Link guarding to lockout/tagout. Make sure procedures cover guard removal during servicing and verification before restart.
- Inspect regularly. Walk the floor with a guarding checklist, record findings and assign corrective actions with due dates.
- Review incidents and near misses. Treat any contact with a moving part as a sign that guarding or procedures need attention.
How SMS360 Helps
SMS360's Audits & Inspections module helps you run machine guarding inspections consistently. Build digital checklists for each machine or area, complete them on a mobile device at the machine, and attach photos of missing or damaged guards. Findings can be assigned as corrective actions with owners and due dates, and dashboards show open items so nothing slips.
Over time, inspection history gives you a record of guarding conditions across your facility, which supports audits and helps you spot machines or areas with repeat problems.
Frequently Asked Questions
What is the OSHA standard for machine guarding?
The general OSHA machine guarding standard is 29 CFR 1910.212, General requirements for all machines. It requires guarding of points of operation, nip points, rotating parts, flying chips and sparks. Other sections of Subpart O, 1910.211 through 1910.219, add rules for specific machines such as woodworking equipment, abrasive wheels and mechanical power presses.
What are the main types of machine guards?
The standard names barrier guards, two-hand tripping devices and electronic safety devices as examples. In practice, employers use fixed guards, interlocked guards, adjustable and self-adjusting guards, and presence-sensing devices such as light curtains. The right choice depends on the machine and how material is fed.
How high must a fan blade be to avoid guarding?
Under 1910.212(a)(5), fan blades must be guarded when their periphery is less than 7 feet above the floor or working level. The guard openings may not be larger than one-half inch. Fans mounted 7 feet or higher are not covered by that paragraph.
Can a push stick replace a machine guard?
No. Paragraph 1910.212(a)(3)(iii) allows special hand tools for placing and removing material only as a supplement to guarding. A push stick or similar tool reduces the need to reach into the danger zone, but the point of operation still needs a guard.
