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.

Flammable Liquids

Class C

Extinguishes electrically charged fires using a non-conductive agent.

Electrical Equipment

Class D

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
