What is the purpose of lockout/tagout procedures?

Lockout/tagout procedures are critical safety protocols used to ensure that machinery is properly shut off and cannot be accidentally started up again during maintenance or servicing activities. This practice protects employees from injuries that could result from the unexpected release of hazardous energy, such as electrical, mechanical, hydraulic, pneumatic, or thermal energy.

When maintenance is performed, the lockout aspect involves securing the energy-isolating device (like a circuit breaker or valve) in a safe position to prevent accidental operation. The tagout component serves as a warning that the machinery should not be operated until the maintenance is completed, and it conveys important information to anyone who might interact with the machinery.

This procedure is vital for employee safety, as it directly addresses the risks associated with unexpected machine startup and helps in creating a safer work environment. The focus on preventing accidental startups is what makes this procedure an essential practice in workplaces where machinery and equipment are operated and maintained.
