🔥 SELF-CONTAINED BREATHING APPARATUS (SCBA) • A Self-Contained Breathing Apparatus permits firefighters to operate safely in atmospheres that cannot support life, including: – Immediately Dangerous to Life and Health (IDLH) conditions – Oxygen-deficient atmospheres (below 19.5% O₂) – Smoke-filled, toxic, superheated, or contaminated air • SCBA is also used when the air is unsafe, irritating, or uncomfortable (heat, smoke, particulates, off-gassing chemicals). ⸻ Composition of SCBA Air Compresse

Fit testing a Self-Contained Breathing Apparatus (SCBA) mask is important to ensure the safety and effectiveness of respiratory protection for firefighters working in hazardous environments. A properly fitting SCBA mask serves as the first line of defense against toxic gases, smoke, and other harmful airborne contaminants. Fit testing verifies that the mask creates a secure and airtight seal around the wearer's face, preventing the ingress of contaminants. Even a small leak can expose the wearer
