In which situations are gas tests required?

Gas tests are required under specific situations to ensure the safety of workers in environments where hazardous gases may be present. These situations can include tasks such as working in confined spaces, during maintenance operations, or when using certain materials that may emit toxic fumes or gases. Conducting these tests helps identify the presence of harmful substances, allowing for appropriate safety measures to be implemented, such as ventilation or personal protective equipment.

The answer indicates that gas tests are not universally needed at all times or under any circumstance but are mandated based on the specific conditions that pose risks to health and safety. This ensures that safety protocols are both appropriate and efficient, targeting the actual risks present in the work environment.
