Material Safety Data Sheet

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. Do not smoke. 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
Do not store, incinerate, or heat this material above 120 degrees Fahrenheit. Keep away from
heat, sparks and open flame. This material can accumulate static charge which may cause spark
and become an ignition source. 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. Store in a
well-ventilated place. Store away from incompatible materials (see Section 10 of the SDS).

Biological limit values
Follow standard monitoring procedures.
Exposure guidelines
Provide adequate ventilation and minimize the risk of inhalation of gas.
Appropriate engineering
controls
Individual protection measures, such as personal protective equipment
Wear approved safety glasses or goggles.
Eye/face protection
Skin protection
Wear appropriate chemical resistant gloves.
Hand protection
Skin protection
Wear protective clothing appropriate for the risk of exposure.
Other
If engineering controls do not maintain airborne concentrations below recommended exposure
limits (where applicable) or to an acceptable level (in countries where exposure limits have not
been established), an approved respirator must be worn.
Respiratory protection
Contact with liquefied gas might cause frostbites, in some cases with tissue damage. Wear
appropriate thermal protective clothing, when necessary.
Thermal hazards
Do not eat, drink or smoke when using the product. Wash thoroughly after handling. Provide
eyewash station and safety shower. Handle in accordance with good industrial hygiene and safety
practices.
