2. 2 © 2009 ARCADIS 2 December 2015 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.

3. 3 © 2009 ARCADIS 2 December 2015 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.

4. 4 © 2009 ARCADIS 2 December 2015 Types of Extinguishers Class 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. Combustible Metals

6. © 2009 ARCADIS 2 December 2015 6 Extinguisher Use  Multi-class Ratings: The new labeling style may show what the extinguisher is NOT suitable for.

7. 7 © 2009 ARCADIS 2 December 2015 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 CO 2 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
