NEBOSH Practice Test

What is a recommended action during the start-up of a process?

1. Complete PTW

2. Remove all safety systems

3. Overfill the storage tanks

4. Skip performance checks

The correct answer is: Complete PTW

Completing a Permit to Work (PTW) is a crucial and recommended action during the start-up of a process. The PTW system is designed to ensure that work is carried out safely and that proper safety protocols are followed before any potentially hazardous activities begin. It acts as a formal document that outlines the work to be done, identifies the hazards associated with that work, and establishes the necessary precautions to minimize risk. By completing the PTW, personnel confirm that all safety checks, necessary training, and assessments of risks have been addressed. This process fosters communication and coordination among team members, ensuring that everyone is aware of their responsibilities and the safety measures in place. It is essential for maintaining a safe working environment, particularly during process start-up, when various operational and safety systems are being activated and adjusted. The other options do not promote safety or compliance with procedures essential for safe operations. Notably, removing safety systems would significantly increase the risk of incidents, overfilling storage tanks could lead to spills or leaks, and skipping performance checks would overlook critical operational parameters necessary for safe functioning. Each of these actions undermines the core principles of health and safety management.
