NEBOSH Practice Test

How does a hot work permit differ from a typical permit-to-work?

1. It does not require a risk assessment

2. It only requires verbal approval

3. It includes gas test details

4. It allows all types of work on site

The correct answer is: It includes gas test details

A hot work permit specifically addresses activities that involve the use of open flames or heat-producing tools, which can pose significant risks of fire or explosions in certain environments. This permit includes critical details regarding gas testing, which ensures that the area where hot work is to be conducted has been assessed for the presence of flammable gases or vapors. By documenting gas test results, the permit helps to facilitate a safer work environment and mitigates potential hazards associated with hot work operations. In contrast, a typical permit-to-work may not necessarily include gas testing details, as it serves as a general authorization for various types of work, which could include tasks that do not inherently pose the same level of risk as hot work. Other elements such as risk assessments and appropriate safety measures may still be necessary depending on the nature of the work being performed, but they are not as specific to gas hazards as those outlined in a hot work permit.
