What is the primary purpose of lockout/tagout procedures?

The primary purpose of lockout/tagout procedures is to prevent unauthorized use of equipment during maintenance or servicing. This safety protocol is critical in ensuring that machinery is completely shut off and cannot be accidentally re-energized while someone is working on it. Lockout/tagout procedures protect workers from the hazards associated with the unexpected release of hazardous energy, such as electrical, mechanical, hydraulic, or pneumatic energy.

By attaching a lock and tag to the equipment's energy-isolating devices, authorized personnel can effectively communicate that the equipment should not be operated. This prevents accidental start-ups, which could lead to serious injuries or fatalities. Establishing these protocols is essential for maintaining a safe working environment and complying with regulations meant to protect workers during maintenance activities.
