OSHA 1910.212 vs. ANSI B11.0-2023: Where Machine Guarding Liability Starts

Frequently Asked Questions

Is OSHA 1910.212 enough for a machine guarding assessment?

It is the legal baseline, but not a full risk assessment method. The article explains that ANSI B11.0 goes further by requiring task-based hazard review and risk reduction across foreseeable machine interactions.

What is the main difference between OSHA 1910.212 and ANSI B11.0-2023?

OSHA 1910.212 focuses on guarding hazardous machine parts. ANSI B11.0 adds a formal process for identifying tasks, estimating risk, and selecting safeguards based on how people actually use, service, and access the machine.

Do I need to assess tasks like jam clearing and cleaning?

Yes. The article emphasizes that setup, cleaning, jam clearing, troubleshooting, and maintenance are often where major gaps appear because they are foreseeable tasks that may not be covered by a basic guard check.

When does ISO 13849 become important?

It becomes important when risk reduction depends on safety-related control functions like interlocks, light curtains, two-hand controls, or stop circuits. It helps determine whether the control system performs reliably enough for the hazard.

How can a JHA help with machine guarding?

A JHA helps by breaking work into job steps, identifying hazards at each step, ranking risk, and documenting recommended engineering and administrative controls. That makes the assessment more usable for training, planning, and corrective actions.
