SECTION IV – FIRE AND EXPLOSION HAZARD OF MATERIAL

Flammability Yes X No o

If yes, under Severe explosion hazard. Severe fire hazard. Vapor/air mixtures are explosive. which conditions: The vapor is lighter than air.  Vapors or gases may ignite at distant ignition sources and flash back.

Means of Extinction If possible, stop the flow of gas. 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. Stay away from the ends of the tanks. Withdraw immediately in case of rising sound from venting safety device or any discoloration of tanks due to fire. Should the flame be extinguished and the flow of gas continue, increase ventilation to prevent flammable or explosive mixture formation.

If no, under which conditions?

Incompatibility to other substances Yes x No o

Incompatible with strong oxidizers (i.e. chlorine, bromine pentafluoride, oxygen difluoride, and nitrogen trifluoride)

Reactivity and under what conditions

The components of this gas mixture do not decompose, per se, but can react with other compounds in the heat of a fire. Cylinders exposed to high temperatures or direct flame can rupture.

Hazardous Decomposition Products

The thermal decomposition products include carbon oxides.

SECTION VII– PREVENTIVE MEASURES

Personal Protective Equipment:

Gloves (specify) N/A

Respiratory (specify): Not required with normal use.

Eye (specify) Safety glasses

Footwear (specify) N/A

Clothing (specify) N/A

Other (specify)

Engineering Controls (e.g., ventilation, enclosed process, specify): No special ventilation systems or engineering controls are needed under normal circumstances of use. Use product in well ventilated areas and in the case of BG-840 use in rooms with greater than 10,000 cu. feet of internal volume in order to keep concentrations well below the LEL in the event of a sudden release of all the gas in the cylinder.

Leak & Spill Procedure: Due to the small size and content of the cylinders (e.g. 105 liters, 580 liters, and 8400 liters of gas), 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 cylinders are relieved of pressure (empty) they are not considered hazardous material or waste. It is acceptable to place empty cylinders in a landfill if local laws permit.

Handling Procedures & Equipment: Cylinders should be firmly secured to prevent falling or being knocked-over.

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

Special Shipping Information: This material is hazardous as defined by 49 CFR 172.101 by the U.S. Department of Transportation. Shipping name: Flammable Gas. Hazard class number and description: 2.1 (Flammable Gas). UN identification number: UN 1971. DOT Label required: Flammable Gas.

SECTION VIII– FIRST AID MEASURES

Skin: N/A

Eye: N/A

Inhalation: This gas mixture is a simple asphyxiant. No unusual health effects are anticipated after exposure to this product, due to the small cylinder 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: N/A

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).
