Red Seal Industrial Mechanic (Millwright) Practice Exam

How do you ensure the safety of machinery during maintenance?

1. Continuously operate the machinery.

2. Use advanced robotics to do the work.

3. Follow lockout/tagout procedures and wear appropriate personal protective equipment (PPE).

4. Never turn off the machinery.

The correct answer is: Follow lockout/tagout procedures and wear appropriate personal protective equipment (PPE).

Ensuring the safety of machinery during maintenance is crucial to prevent accidents and injuries. Following lockout/tagout procedures is a fundamental practice that involves disabling machinery and securely tagging it to ensure that it cannot be accidentally re-energized while maintenance is being performed. This procedure is designed to protect workers by isolating hazardous energy sources and making the maintenance process safer. Wearing appropriate personal protective equipment (PPE) is equally important, as it provides an additional layer of safety against potential hazards that may arise during maintenance activities. This can include gloves, safety glasses, hard hats, and other gear designed to protect against specific risks associated with the equipment being serviced. Using advanced robotics, while a modern solution, does not always apply to every situation and may not eliminate the need for human oversight or intervention. Additionally, continuously operating machinery or never turning it off directly contradicts safety protocols, as these practices would increase the risk of accidents during maintenance operations.
