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.

Leak & Spill Procedure: Uncontrolled releases should be responded to by trained personnel using pre-planned procedures. Proper protective equipment should be used. In case of a controlled rapid release of gas, clear the affected area, protect people, and respond with trained personnel. Care should be taken to avoid contact with rapidly expanding gases.

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, 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: Compressed gas, n.o.s. (Rare gas and air mixtures). Hazard class number and description: 2.2 (Non-Flammable Gas). UN identification number: UN 1956. DOT Label required: Non-Flammable Gas.

SECTION VIII– FIRST AID MEASURES
