Specification

Eliminate all ignition sources (no smoking, flares, sparks, or flames in immediate area). Keep
combustibles (wood, paper, oil, etc.) away from spilled material. Stop leak if you can do so without
risk. If possible, turn leaking containers so that gas escapes rather than liquid. Isolate area until
gas has dispersed. For waste disposal, see section 13 of the SDS.
Methods and materials for
containment and cleaning up
Should not be released into the environment. Prevent further leakage or spillage if safe to do so.
Environmental precautions
7. Handling and storage
Keep away from heat/sparks/open flames/hot surfaces. - No smoking. Do not handle, store or
open near an open flame, sources of heat or sources of ignition. Protect material from direct
sunlight. All equipment used when handling the product must be grounded. Do not breathe gas.
Avoid prolonged exposure. Do not enter storage areas or confined spaces unless adequately
ventilated. Use only outdoors or in a well-ventilated area. Oxygen concentration should not fall
below 19.5 % at sea level (pO2 = 135 mmHg). Mechanical ventilation or local exhaust ventilation
may be required. Wear appropriate personal protective equipment. Observe good industrial
hygiene practices.
Precautions for safe handling
Store at temperatures not exceeding 49°C/120°F. Keep away from heat, sparks and open flame.
Prevent electrostatic charge build-up by using common bonding and grounding techniques. Store
in a cool, dry place out of direct sunlight. Cylinders should be stored upright, with valve protection
cap in place, and firmly secured to prevent falling or being knocked over. Protect cylinders from
damage. Stored containers should be periodically checked for general condition and leakage.
Store in original tightly closed container. Keep container tightly closed. Store in a well-ventilated
place. Use care in handling/storage. Store away from incompatible materials (see Section 10 of
the SDS).

Provide adequate ventilation and minimize the risk of inhalation of gas. Use process enclosures,
local exhaust ventilation, or other engineering controls to control airborne levels below
recommended exposure limits.
