Florida Drinking Water Operator "B" Practice Test

What is the most important step an operator should perform before starting maintenance on a motor and/or pump?

1. Inspect the equipment for leaks

2. Run the motor to ensure it is functioning

3. Review and perform the lockout tagout procedure

4. Check the electrical connections

The correct answer is: Review and perform the lockout tagout procedure

The most important step an operator should perform before starting maintenance on a motor and/or pump is to review and perform the lockout tagout procedure. This procedure is critical because it ensures that hazardous energy sources are properly controlled and de-energized before any maintenance work begins. By implementing lockout/tagout, the operator prevents accidental startup or the release of stored energy, which could result in severe accidents, injuries, or even fatalities. This procedure involves placing a lock and tag on the energy isolating devices to indicate that maintenance is in progress. This not only protects the worker performing maintenance but also ensures that no one else inadvertently re-energizes the system while repairs are being made. It's essential to prioritize safety in any maintenance operation, and the lockout/tagout procedure is a crucial aspect of workplace safety protocols in industrial settings. By adhering to this procedure, operators demonstrate their commitment to creating a secure working environment.
