NEBOSH Practice Test

Which of the following is a method for controlling ignition sources during hot work?

1. Removing all electrical equipment

2. Monitoring weather conditions

3. Using fire blankets

4. Conducting a safety drill

The correct answer is: Using fire blankets

Using fire blankets is an effective method for controlling ignition sources during hot work. Fire blankets serve as a protective barrier that can help contain sparks, spatter, or flames generated by activities like welding or cutting. By placing fire blankets in strategic locations around the work area, you can significantly reduce the risk of a fire starting from ignitable materials nearby. The use of fire blankets is part of a broader approach to fire safety during hot work, which also includes housekeeping measures to ensure flammable materials are removed from the vicinity. While the other options might relate to safety considerations, they do not directly address the control of ignition sources in the same way that fire blankets do. For example, removing all electrical equipment may not be practical or effective in controlling ignition during hot work, and monitoring weather conditions or conducting a safety drill are important but serve different purposes in the overall safety strategy.
