What should attendants NOT do if an entrant becomes unconscious in a confined space?

When dealing with a situation where an entrant becomes unconscious in a confined space, the appropriate course of action must prioritize safety for everyone involved. Attempting to enter and perform a rescue is not advisable because it can put the rescuer in danger. Confined spaces often have hazardous atmospheres or conditions that can also incapacitate an unprotected rescuer, leading to further emergencies.

Instead, the safest approach is to call for emergency personnel who are trained and equipped to handle such situations. This ensures that the rescuers can enter the space with the appropriate protective equipment and support. Ventilation can be useful before or after emergency personnel arrive, but it must be done cautiously and follows protocols to ensure that the atmosphere is safe.

Leaving the area immediately can be the right action if staying could expose someone else to danger, but it should be done with the intent to alert others and call for help, ensuring that proper emergency response protocols are followed.
