Under what circumstances could equipment be operated when tagged with DANGER tags?

Correct Answer: Option D — Under NO circumstances should the equipment be operated when tagged.

Lock-out/Tag-out (LOTO) procedures under OSHA and 46 CFR mandate that DANGER tags signify equipment is isolated for maintenance. Operating tagged equipment creates an immediate hazard to personnel. Safety protocols strictly prohibit bypassing these tags, as they serve as the primary defense against accidental energization and catastrophic injury during repairs.
