Extinguisher Use• Fire extinguishers should be located

throughout your office and marked with a fire extinguisher sign.

• Fire extinguishers may be located in field vehicles and should be securely mounted.

• ARCADIS does not require anyone to use a fire extinguisher unless required at a client site.

• Never attempt to use an extinguisher if there is any question that your personal safety could be compromised. Your safety comes first!

• When using a fire extinguisher, keep your back at and to the door, and front to the fire so you can exit quickly.


Extinguisher Use• The “Old” extinguisher labeling system recognizes

four classes of extinguishers:

• Class A, B, C and D

• As seen in the next slide, the new extinguisher labeling system uses pictures to identify the type of fire the extinguisher and for what type of fires it can be used.


Types of ExtinguishersClass A

Extinguishes ordinary combustibles such as wood and paper.

Ordinary Combustibles

Class B

Extinguishes flammable liquids such as grease, gasoline and oil.

Flammable Liquids

Class C

Extinguishes electrically charged fires using a non-conductive agent.

Electrical Equipment

Class D

Used for fires involving flammable metals. The extinguisher is often specific to the metal type.

Extinguisher Use

Multi-class Ratings: Many extinguishers used today can be used on different types of fires and will be labeled with more than one type of designator.


Extinguisher Use

Multi-class Ratings: The new labeling style may show what the extinguisher is NOT suitable for.


Common Types of Extinguishers• Dry Chemical

– Usually rated for multi-purpose use

– Contains extinguishing agent and uses compressed, non-flammable gas as a propellant

• Carbon Dioxide– Most effective on liquid and electrical fires (Class B and C)

– Since the gas disperses quickly there is a limited range of 3-8 feet

– The CO2 is stored as a compressed liquid. As it expands, it cools the surrounding air. Causes ice to form on the horn of the extinguisher

– Limited range of 4-8 feet

• Water– Contains water and compressed gas

– Should only be used on combustible, Class A fires


Using a Fire Extinguisher

When using an extinguisher remember PASS:

Pull

Aim

Squeeze

Sweep



Pull – Pull the pin at the top of the extinguisher that keeps the handle from accidentally being pressed.



Aim – Aim the nozzle toward the base of the fire.



Squeeze – Stand approximately 8 feet away from the fire and squeeze the handle to discharge the extinguisher. If you release the handle, the discharge will stop.



Sweep – Sweep the nozzle back and forth at the base of the fire.



Once the fire is extinguished, watch closely in case fire re-ignites.
