Danger do not operate men working on machinery tags use official OSHA headers for machine safety protocol and compliance. The objective of do not operate men working on machinery tags is to notify staff that there is immediate danger present and the machine is currently undergoing maintenance. These danger men working on machinery tags are useful tools to help protect the health and safety of personnel, but are not a substitute for required protective measures for eliminating or reducing hazards. These tags comply with the OSHA 1910.145 standard, where the danger tags indicate an imminently hazardous situation, which, if not avoided, will result in death or serious injury. Durable UV resistant black nylon ties that have 50 lb. of tensile strength are included for easy attachment.
