Extinguishing Media:

Class b fire extinguishing media such as halon, co2 or dry chemical can be used. Fire fighting should be attempted only

by those who are adequately trained.

Special Fire Fighting Procedures:

Stop the flow of gas and allow fire to burn out. Extinguishing the flame before shutting off the supply can cause the

formation of explosive mixtures. In some cases it may be preferred to allow the flame to continue to burn. Keep the

surrounding area cool with water spray and prevent further ignition of combustible material.
