Conditions for safe storage,
including any incompatibilities
Store in accordance with local, regional, national, and international regulations. Secure cylinders in
an upright position at all times, close all valves when not in use. Store in a cool, dry, well-ventilated
place. Keep container tightly closed and sealed until ready for use. Protect cylinders from damage.

Appropriate engineering
controls
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.
Individual protection measures, such as personal protective equipment
Eye/face protection
Wear approved safety glasses or goggles.
Skin protection
Hand protection
Wear appropriate chemical resistant gloves.
Other
Wear protective clothing appropriate for the risk of exposure.
Respiratory protection
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.
Thermal hazards
Contact with liquefied gas might cause frostbites, in some cases with tissue damage. Wear
appropriate thermal protective clothing, when necessary.
General hygiene
considerations
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.
