Machine guarding is one of the most common OSHA citation areas in manufacturing. The requirement is straightforward: moving parts that can cause injury must be properly guarded.
If a machine can cut, crush, pinch, or catch, it needs guarding.1
Any shop with machinery that has moving parts.
That includes CNC machines, presses, conveyors, grinders, saws, and fabrication equipment. If employees work around equipment with exposed motion or energy, machine guarding applies.
That covers most manufacturing environments.
Not just operators.
Anyone who works on or around machines needs to understand guarding. That includes operators, maintenance, setup personnel, supervisors,and even cleaning staff.
If they are exposed to the hazard, they need to recognize it.
Before exposure to the hazard.
Training and review should happen when:
In practice, many shops reinforce machine guarding expectations regularly because conditions change over time.
Machine guarding is about preventing contact with hazardous motion.
Guards must protect against:
Training should cover:
Guarding must match the machine and the hazard. There is no one-size-fits-all solution.2
Most machine guarding issues are not about missing guards.They are about guards being bypassed or ineffective.
Typical gaps include:
As one safety professional noted, bypassed interlocks on CNC machines are extremely common in real shops, often justified for setup or visibility, even though they create serious risk and have led to OSHA citations.3
Another common theme in audits is not missing guards entirely, but inconsistencies in how guarding is applied, maintained, or verified across different machines.4
Machine guarding failures often happen during setup, maintenance, or when production pressure is high.
Do not over-complicate it.
Start by identifying where employees could come into contact with moving parts. Make sure guards physically prevent that contact. Then train employees on what the guards do and why they cannot be bypassed.
Reinforce it regularly, especially when equipment or processes change.
In practice, OSHA is looking for three things:
Common documentation includes hazard assessments, equipment inspections, and training records.

Machine guarding is about preventing contact with moving parts. If a hazard is accessible, the guarding is not doing its job.
