SECTION IV – FIRE AND EXPLOSION HAZARD OF MATERIAL

Flammability  

Yes X   No o

If yes, under          Fire hazard.  Vapor/air mixtures are explosive.  The vapor is heavier than air.

which conditions:   Vapors or gases may ignite at distant ignition sources and flash back.

Means of Extinction

Extinguish with carbon dioxide, regular dry chemical.

Special Procedures:  Move container from fire area if it can be done without risk.  Cool containers with water spray until well after the fire is out.  Should the flame be extinguished and the flow of gas continue, increase ventilation to prevent flammable or explosive mixture formation.

which conditions?

Incompatibility to other substances

Yes x   No o

If so,               Butane is incompatible with strong oxidizers (i.e. chlorine,

Which ones?   bromine pentafluoride, oxygen difluoride, and nitrogen trifluoride)

Reactivity and under what conditions

 

Butane does not decompose,but can react with other compounds in the heat of a fire.  Containers exposed to high temperatures or direct flame can vent or rupture.

 

 

Hazardous Decomposition Products

 

The thermal decomposition of products of butane include carbon oxides.

SECTION VII– PREVENTIVE MEASURES

Personal Protective Equipment:

Respiratory (specify):  

Not required with normal use.

Eye (specify):

Not required with normal use.

Footwear (specify)

N/A

Clothing (specify)

N/A

Other (specify)

 

Engineering Controls (e.g., ventilation, enclosed process, specify):    Due to the small size and content of the container no special ventilation systems or engineering controls are needed under normal circumstances of use.

Leak & Spill Procedure:  Due to the small size and content of the container an accidental release of this product presents significantly less risk of an oxygen deficient environment and other safety hazards than a similar release from a larger cylinder.

Waste Disposal:  Once the containers are relieved of pressure (empty) they are not considered hazardous material or waste.  It is acceptable to place empty containers in a landfill if local laws permit.

Handling Procedures & Equipment:  N/A

 

Storage Requirements: Containers must be protected from the environment, and preferably kept at room temperature.  Containers should be stored in dry, well ventilated areas, away from sources of heat, ignition, and direct sunlight. 

Special Shipping Information:  This material is hazardous as defined by 49 CFR 172.101 by the U.S. Department of Transportation.  Shipping name: Butane.  Hazard class number and description: 2.1 (Flammable Gas).  UN identification number: UN 1011.  DOT Label required: Flammable Gas.  

SECTION VIII– FIRST AID MEASURES

Skin:  Contact with liquid: If frostbite or freezing occur, immediately flush with plenty of lukewarm water (105-115 oF; 41-46 oC).  Do not use hot water.  If warm water is not available, gently wrap affected parts in blankets.  Get immediate medical attention.

Eye:  Contact with liquid: Immediately flush eyes with plenty of water for at least 15 minutes.  Then get immediate medical attention.

 

Inhalation: No unusual health effects are anticipated after exposure to this product, due to the small container size.  If any adverse symptom develops after over-exposure to this product, remove victim(s) to fresh air as quickly as possible.  Only trained personnel should administer supplemental oxygen and/or cardio-pulmonary resuscitation if necessary.

Ingestion: If a large amount is swallowed, get medical attention

 

General Advice:  Victim(s) who experience any adverse effect after over-exposure to this product must be taken for medical attention.  Take a copy of the label and the MSDS to physician or other health professional with victim(s).
