Danger do not operate electricians at work tags use official OSHA headers for machine safety protocol and compliance. The objective of danger do not operate electricians at work tags is to notify staff that there is immediate danger present during attempted use of equipment. These danger do not operate 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.
