Which arm should be the first to put through the shoulder strap when donning the SCBA?

When donning the SCBA (Self-Contained Breathing Apparatus), the correct procedure is to first put the right arm through the shoulder strap. This process is generally designed to ensure that the SCBA is secured properly and allows for a smooth, efficient donning of the equipment. By starting with the right arm, the wearer can maintain control of the apparatus while positioning it correctly on the back.

This method helps the user to stabilize the SCBA as they maneuver it into place, allowing the other arm to follow through more easily. Proper sequencing is crucial for safety and effectiveness, particularly in emergency situations where time and efficiency are critical. Following the correct donning procedure not only ensures the SCBA is fitted snugly but also minimizes the chances of it shifting or becoming dislodged during use, which can be vital in hazardous environments.
