What should be a priority when entering a confined space?

When entering a confined space, the priority should be on atmospheric conditions. This is crucial because hazardous atmospheres can pose immediate dangers, such as the presence of toxic gases, flammable substances, or insufficient oxygen levels. Prioritizing atmospheric conditions ensures that individuals are aware of any potential breathing difficulties or fire risks before entering, allowing them to take necessary precautions such as using air monitoring devices, providing ventilation, or utilizing personal protective equipment.

While other factors, such as engulfment hazards, structural integrity, and temperature control, are also important considerations when working in confined spaces, they become secondary to the immediate threat that poor atmospheric conditions can pose. Addressing atmospheric conditions first ensures the safety and health of individuals involved, making it a fundamental step in confined space entry protocols.
