How long does the PBE typically last when in use?

The Personal Breathing Equipment (PBE) is designed to provide emergency oxygen and a breathable atmosphere for personnel working in environments where smoke, toxic gases, or other hazardous conditions may be present. When utilized correctly, the PBE typically lasts around 15 minutes, providing ample time for the user to carry out necessary actions, such as evacuating or addressing the emergency situation.

This duration is critical because it gives individuals a specific window to operate in hazardous situations without being significantly impaired by harmful substances. The equipment is engineered to allow for sufficient time to clear a space, find safe exits, or take other essential actions. This duration is also established based on safety standards and operational needs in emergency situations, balancing between functionality and user safety.
