Which statement about workers entering confined spaces is NOT correct?

In the context of confined space entry, the statement regarding ventilation being "always required" is not accurate because ventilation requirements can vary based on the specific conditions and nature of the confined space. While proper ventilation is often vital to ensure that air quality is safe and to prevent the accumulation of hazardous gases, there may be scenarios where alternative methods are employed to ensure safety, and ventilation isn't feasible or required under certain conditions.

For instance, a confined space that is inherently safe due to its environment or a short-duration task might not necessitate continuous ventilation if the risk of hazardous atmospheres is low. Alternatively, if adequate air monitoring is being conducted and conditions are confirmed safe, specific circumstances might allow limited entries without active ventilation.

On the other hand, workers must indeed receive proper training before entering confined spaces to ensure they understand the risks involved and the necessary precautions. Additionally, having a monitor present outside the confined space is crucial for maintaining safety by overseeing the entry and ability to assist in emergencies.
