Fire Extinguisher

Required safety equipment in every RV, typically mounted near the entrance. Must be inspected and certified.

Also called: fire extinguisher, RV fire extinguisher, ABC extinguisher

A fire extinguisher is required safety equipment in every RV, typically mounted near the entrance for quick access. Most RVs use ABC-rated dry chemical extinguishers — effective on:

  • A (Class A): Ordinary combustibles (paper, wood, fabric)
  • B (Class B): Flammable liquids (gasoline, propane)
  • C (Class C): Electrical fires

RV fire extinguisher sizes

  • Most common: 2.5-5 lb ABC extinguishers
  • Larger rigs may have: multiple smaller extinguishers in different locations
  • Standalone tanks for propane storage areas

Inspection at pickup

Before driving away, verify:

  1. Pressure gauge in green zone (not red)
  2. Inspection date current (most expire 5-12 years from manufacture)
  3. Pin in place and seal intact
  4. Hose attached and undamaged
  5. Mounting bracket secure

An expired or empty fire extinguisher should not be on a rental. Ask for replacement before driving away.

How to use a fire extinguisher (PASS method)

  1. Pull the pin (it has a safety pin/seal)
  2. Aim at the base of the fire (not at the flames)
  3. Squeeze the lever
  4. Sweep side to side, covering the base

A standard 5 lb ABC extinguisher provides 8-12 seconds of discharge. Don’t waste it on flames; aim at the base.

When to fight vs. flee

Fight a fire only when:

  • You can reach the extinguisher quickly
  • The fire is small (cooking pan size, small electrical)
  • You have a clear escape path
  • You’re confident you can contain it

Flee immediately when:

  • Fire is spreading
  • You can’t see clearly
  • Smoke is heavy
  • Multiple flames
  • Anything related to fuel tank or propane

Life first. Possessions never. The RV is replaceable; you aren’t.

RV-specific fire risks

  • Cooking — most common; turn off propane before grease fires
  • Propane appliances — leaks can ignite
  • Electrical wiring — overloaded circuits, frayed wires
  • Generator — exhaust heat, fuel leaks
  • Refrigerator coil — older absorption fridges can ignite

Common rental issues

  • Expired extinguisher — easy to overlook; check date at pickup
  • Low pressure — gauge in red zone; needs recharging
  • Damaged bracket — won’t stay mounted while driving
  • Wrong type — Class B-only extinguisher inadequate for RV use

The BestRV testing methodology includes verifying fire extinguisher status on every test rental. We’ve found expired extinguishers on multiple test rentals from major fleets.

Multi-extinguisher setup

For larger rigs:

  • One near the entrance
  • One in the rear bedroom
  • One near the cooking area (small kitchen extinguisher)
  • One outside in storage compartment for exterior fires

If your rental has only one, consider buying a small 2.5 lb backup for $25-$40 to add a second.
