What must an employer do when there is a suspicion of a hazardous atmosphere?

When there is a suspicion of a hazardous atmosphere, testing the atmosphere is crucial because it allows the employer to determine the actual levels of hazardous substances present. This ensures that the work environment is safe for workers by identifying potential dangers, such as toxic gases, low oxygen levels, or flammable vapors. Testing should be carried out using appropriate methods and equipment to provide accurate and reliable readings.

It's important for employers to take proactive steps in safeguarding the health and safety of their employees. By testing the atmosphere, the employer can make informed decisions regarding the need for ventilation, additional protective measures, or possible evacuation. This approach helps prevent accidents and injuries that could result from working in an unsafe environment.
