Smoke causes most fatalities. SCBA (Self-Contained Breathing Apparatus) is essential.

Key training points:

• Donning procedure: Check mask seal, cylinder pressure (> full), low-air alarm.
• Working in teams: Lifeline signals, communication, search patterns.
• Rescue: Locate casualty, share air if needed, carry out safely.
• Consumption: Panic breathing uses air fast — stay calm, move deliberately.

Exit before low-air alarm sounds.
