Front and back labels with writable fields for work information enable precise documentation of lockout tasks. This lockout tagout tag card is designed for industrial and manufacturing environments to enforce safety regulations and prevent accidents. Lockout tags are versatile and suitable for a wide range of settings, including industry, chemical, energy, petroleum, coal, and other workplaces where energy isolation is required. The facility tag clearly instructs employees not to operate devices that are currently locked, supporting clear communication and compliance during maintenance and repair. Label legends provide unambiguous hazards: on the front, there is a danger message stating do not operate because the device is locked; on the back, there is a danger message not to remove this label. Use scenarios: - During routine maintenance on a factory machine, to isolate electrical or mechanical energy and prevent unexpected startup. - In a chemical plant, to shut down and service process equipment safely, ensuring all energy sources remain isolated. - In oil, gas, or coal facilities, to tag out systems undergoing inspection or repair, preventing inadvertent energization. This product supports safety procedures with clear, durable messaging and straightforward documentation, helping ensure proper lockout/tagout practices across multiple industries.
