What is the best protection against hand injuries from pinch points associated with being required to perform maintenance or repairs on rotating machinery?

Correct Answer: Option B — Properly locking out and tagging out the machine before work begins.

Lockout/Tagout (LOTO) procedures, mandated by OSHA and USCG safety standards, physically isolate energy sources from machinery. This ensures that equipment cannot be inadvertently energized or rotated while personnel are performing maintenance, providing the only absolute protection against mechanical pinch points and accidental startup during repair operations.
