What tag is used to prohibit the operation of equipment?

The tag used to prohibit the operation of equipment is the Danger tag. This tag indicates a serious hazard that may result in severe injury or death if the equipment is operated while the tag is in place. It is essential to prevent any unintended operation of the equipment to ensure the safety of personnel working on or around it.

The emphasis of the Danger tag is on the urgent need for caution, clearly communicating that the equipment should not be operated under any circumstances until the situation is resolved. Such clarity is critical in a workplace where heavy machinery or hazardous materials are involved.

In contrast, other tags like Warning may indicate potential hazards but do not necessarily imply immediate danger or the absolute prohibition of operation. Maintenance tags typically suggest that equipment is being serviced or is temporarily not available for use, while Out of Service tags may indicate equipment is not operational but do not carry the same severity of hazard as the Danger tag.
