What should you check during the pre-use inspection of the SCBA?

During the pre-use inspection of the SCBA, it is crucial to check not just the cylinder pressure, but also the condition of the harness and the seal of the facepiece. This thorough inspection ensures that all parts of the SCBA function optimally to provide maximum protection for the user.

The cylinder pressure check ensures that there is enough air supply for the intended use, important for safety and effectiveness in emergency situations. Assessing the harness condition confirms that it is secure and free from any damage or wear that might affect the SCBA's performance or the user's safety. Checking the facepiece seal is vital because an inadequate seal can allow contaminated air to enter, compromising the user's respiratory safety.

Focusing on all three aspects during the pre-use inspection helps to ensure that the SCBA is fully functional and safe for use in hazardous environments, providing the wearer with reliable protection.
