What safety measure should be taken when entering a confined space?

When entering a confined space, it is crucial to post another worker outside the space as a safety measure. This practice is essential because the worker outside can monitor conditions and be a first responder in the event of an emergency. Confined spaces may have hazardous atmospheres or situations that can lead to accidents or incapacitation of those inside. The colleague stationed outside can quickly call for help or assist in the rescue, which is vital for ensuring the safety of anyone who might be at risk.

In addition to having a worker outside, there are various other safety protocols that one should follow when entering such spaces. While ensuring proper lighting, working in teams, and wearing protective gear such as gloves and goggles are also important considerations, having someone positioned outside provides a critical safety link in emergencies.
