Answer 1

Before doffing SCBA, ensure you are out of the contaminated area and remove the facepiece first. After removing the facepiece, you can then proceed to remove the other components of the SCBA, such as the regulator, cylinder, and harness, in order to properly doff the equipment.

Step-by-step explanation:

Before doffing SCBA, it is important to ensure that you are out of the contaminated area and remove the facepiece first. The facepiece is the part of the SCBA that covers the nose and mouth and provides the wearer with clean air to breathe.

After removing the facepiece, you can then proceed to remove the other components of the SCBA, such as the regulator, cylinder, and harness, in order to properly doff the equipment.

By following these steps, you can safely remove the SCBA and ensure that you are no longer exposed to any contaminants in the area.
