5.2 Fire Safety

The Fire Triangle and Why Healthcare Fires Are Deadly

Fire needs three things - fuel, heat, and oxygen - known as the fire triangle. Remove any one and the fire dies. Healthcare fires are especially dangerous because residents have limited mobility, oxygen therapy is common, and smoke incapacitates quickly. The exam tests two acronyms relentlessly: RACE for what you do, in order, and PASS for how you run an extinguisher.

RACE: The Order of Response

The sequence matters. Rescuing people in immediate danger always comes before fighting the fire.

PASS: Operating the Extinguisher

Aim at the base of the fire, not the visible flames, because the base is where the burning fuel is.

Only fight a fire if it is small, you have a clear exit behind you, and the room is not filling with smoke. When in doubt, evacuate.

Oxygen: The Hidden Accelerant

A tested fact: oxygen itself does not burn, but it makes everything else burn faster and hotter. Around any "Oxygen in Use" sign:

• No smoking, candles, matches, lighters, or open flames anywhere nearby.
• No electrical razors, heating pads, or equipment that can spark near the tank or tubing.
• Avoid wool blankets and synthetic fabrics that build static; petroleum-based lip balm near oxygen is also a hazard.
• Store cylinders upright and secured so they cannot fall and rupture.

Evacuation: Horizontal Before Vertical

Move residents horizontally to the next smoke compartment behind a fire door first; that is usually enough. Use vertical evacuation down the stairs only if a whole floor is threatened. Never use an elevator during a fire - it can stall at the fire floor or fill with smoke.

Evacuation priority by mobility:

Prevention and Drills

The CNA reports frayed cords, overloaded outlets, and blocked exits, and keeps fire doors unobstructed - propping a fire door open defeats containment because closed fire doors are rated to hold back smoke and flame for a set time. Space heaters and candles are prohibited in resident areas, and electrical equipment brought from home must be inspected by maintenance before use. During mandatory fire drills, know the location of the nearest pull station, extinguisher, and two exit routes from every assignment.

Common Ignition Sources in Long-Term Care

The exam ties fire prevention to everyday CNA observation. The most common ignition sources you are expected to watch for and report include unattended cooking and microwave use, smoking materials (residents who smoke must do so only in designated, supervised areas, never in bed), overloaded power strips, malfunctioning call-light or bed motors that smell hot, and any heat source near oxygen tubing. Linen carts and trash should never block a corridor, because corridors are the evacuation route and the firefighters' access path.

Recognizing and Reporting Early Signs

A fire rarely starts as open flame. The earliest sign is often the smell of smoke, an electrical or burning-plastic odor, a warm wall or door, or a flickering or sparking outlet. Before opening any door during a suspected fire, use the back of your hand to feel it - a hot door means fire on the other side, so do not open it. Smoke rises and is most toxic at standing height, so if you must cross a smoky area, stay low where the air is clearer. These habits, combined with RACE, are what the exam rewards.

The PASS-After-RACE Relationship

Students confuse the two acronyms. RACE is the overall plan you follow when you discover any fire; PASS is only the technique inside RACE's final "E" step, used when you have decided it is safe to extinguish a small, contained fire. You never reach for PASS before completing Rescue, Alarm, and Contain. Keeping that hierarchy straight resolves most exam fire questions.

Worked Scenario

A small wastebasket fire ignites in a room where a resident is receiving oxygen. The correct order is RACE: first Rescue the resident out of the room, then Alarm by pulling the station, then Contain by closing the door, and only then consider Extinguishing if the fire is still small and you have a clear exit. Pulling the alarm before removing the resident, or fighting the fire while the resident remains beside an oxygen source, are the classic wrong answers.
