During a confined space entry, what should an employer continuously monitor?

The correct answer is the ambient conditions of the confined space. Continuous monitoring of the ambient conditions is essential for ensuring the safety of employees working in confined spaces. These conditions can include levels of oxygen, flammable gases or vapors, and the presence of toxic substances. Changes in these conditions can pose serious hazards to workers, including the risk of suffocation or exposure to harmful agents. By keeping track of these parameters, employers can proactively manage risks and implement necessary safety measures, such as evacuating personnel or providing fresh air.

Monitoring employee morale, the number of breaks, or compliance with permits, while important in a general workplace context, does not directly address the immediate health and safety risks associated with confined space entry. The focus in such environments needs to be on the physical conditions that could endanger workers, making ambient condition monitoring a critical component of confined space safety protocols.
