Given hazards and extinguishment techniques, the student will be able to demonstrate the process to safely extinguish a vehicle fire.

Topic: Vehicle Firefighting

Time Required: 2 Hours

Materials:

• Appropriate visuals

• water supply

• fully equipped fire engine

• PPE and SCBA for each participant

• vehicles

• Class A fuel if the vehicles are to be on fire

• at least one instructor for each fire students

• safety officer

· Essentials Of Fire Fighting, Fourth Edition, IFSTA

Preparation: Remove fuel tanks if vehicles are to be burned and chock wheels to prevent unexpected movement.

Motivation: Vehicle fires are either a minor fire or a total loss. In either case, firefighters should take such fires seriously and not become complacent. There are inhalation and explosive hazards that must be considered when attacking vehicle fires.

Objective (SPO): Given hazards and extinguishment techniques, the student will be able to demonstrate the process to safely extinguish a vehicle fire.

Overview: Vehicle Firefighting

· Safety Hazards

· Extinguishment Techniques

• Fire Attack Practical

Instructors Notes: The practical activity can be conducted with or without fire but should involve the use of vehicles that can be used for this purpose. If the vehicles are to be ignited, fuel tanks should be removed prior to the session.

Instructional Guide

I. SAFETY HAZARDS (1-1)

Types of Vehicles - discuss the potential hazards with each type of vehicle

• Automobiles

• Small trucks

• Vans - service and passenger

• Buses - school and commercial

• Recreational vehicles = towed or self-contained

Fuels - discuss the hazards associated with each type of fuel

• Gasoline/gasoline mixtures - some jurisdictions now have gasoline with a 10% ethanol mixture

• Diesel

• LPG/CNG

• Solar or electric (alternative fueled)

• Hydrogen

Vehicle components - discuss how vehicle components can contribute significantly to the spread of the fire as well as present additional safety concerns.

• Fuel injection system - fuel vapor under pressure

• Drive shaft - closed hollow tubes

• Battery or batteries - explosive hazard with acid

• Coleman stoves/LPG tanks - additional fuel or pressurized vessel

• Cargo - could be explosive

• Struts/hatch back pistons - closed pressure cylinders

• Energy absorbent bumpers - pressurized shock absorbers

• Supplemental Restraint Systems (SRS)/Side Impact Restraint Systems (SIPS) - potential for airbag to operate or activation mechanism to explode

• Combustible metals - may require a special extinguishing agent

• Air conditioning systems - pressurized system with refrigerant gas

• Interior finishes and upholstery - plastics, form, fabric

• Tires - pressurized container

• Fuel tanks - fuel and pressure build-up

• Windshields - explosion hazard when vehicle completely closed

Proximity to exposures

• Service stations - especially if inside or near fuel islands

• Structures - especially if vehicle is inside

• Hazardous materials/explosives - may be ignition source for leaking vapors

• Other vehicles - salvage yards, auto dealerships, or parking areas

• Traffic - access as well as exposure

• Crowds of people - life safety hazard

II. EXTINGUISHMENT TECHNIQUES (1-2)

Fire Attack

• Full personal protective clothing and SCBA

• Use at least one 1-1/2" attack line

• Consider a backup line

• Approach from upwind and uphill if possible

• Approach cautiously and at the corners of the vehicle

• Place stream between exposures and involved vehicle

• Attack fire on ground first
