OSHA OSHA - Safety Certificate Machine Guarding Requirements Questions and Answers 2 — Questions and Answers
Question 1: Under OSHA standards, which of the following is a primary method of machine guarding used to prevent worker contact with hazardous moving parts?
- Barrier guards (Correct answer)
- Warning labels
- Safety meetings
- Color-coded flooring
Correct answer: Barrier guards
Barrier guards are a primary safeguarding method recognized by OSHA to physically prevent contact with dangerous machine parts.
