What is the first step you should take before working on mechanical power transmission equipment?

Before working on mechanical power transmission equipment, the most critical first step is to ensure that the machine power is off and locked out. This process, known as lockout/tagout (LOTO), is essential for maintaining safety while performing maintenance or repairs.

Lockout/tagout procedures are designed to prevent accidental re-energization of equipment during maintenance activities. By turning off the power and using a lock and tag system, workers can ensure that the equipment cannot be started inadvertently, which significantly reduces the risk of injury. This practice is a core aspect of workplace safety protocols and is mandated under occupational safety regulations.

While it is also important to ensure the machine is lubricated, inspect it for damages, and check for loose bolts, these actions should only be taken once it is confirmed that the machine is completely powered down and cannot operate. Thus, implementing lockout/tagout procedures is crucial in establishing a safe working environment and should always be the first step before any maintenance work begins.
