What tag is used to prohibit the operation of equipment?

• A. Danger Tag
• B. Caution Tag
• C. Safe Tag
• D. Maintenance Tag

Answer: (A)

When equipment must not be operated because of an immediate hazard, a tag that clearly communicates “do not operate” is used. This is the Danger Tag. It signals a real danger and pairs with lockout procedures to ensure the equipment cannot be restarted until the hazard is addressed and the tag is deliberately removed by an authorized person. The other options don’t convey the same level of prohibition: a Caution Tag flag indicates a potential risk but not an immediate, strong prohibition, a Safe Tag isn’t a standard safety term, and a Maintenance Tag may indicate out-of-service for upkeep but isn’t inherently about stopping operation due to a hazardous condition.
