What is one of the initial steps when donning SCBA?

One of the initial steps when donning a Self-Contained Breathing Apparatus (SCBA) is ensuring that the air cylinder is fully charged. This is critical because a fully charged air cylinder provides the user with the necessary air supply for a safe duration while working in hazardous environments. If the air cylinder is not fully charged, the user may face a significant risk of running out of breathable air, potentially leading to life-threatening situations.

Starting the donning process by checking the charge status ensures that the SCBA will operate effectively throughout the mission. It is essential for personnel to prioritize this step before addressing other aspects of the SCBA setup, such as adjusting the mask fit or inspecting the assembly. Ensuring the air supply is adequate lays the foundation for all subsequent actions and contributes to the overall safety and effectiveness of the operation.
