Hazards and Protection.
Storage
Store at room temperature.
Handling
Handle in accordance with all current regulations and standards.
Protection
Wear appropriate protective gloves, clothing and goggles. Always wear thermal protective clothing when handling refrigerated/cryogenic liquids.
Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).
Small spills/leaks
Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Attempt to stop leak if without undue personnel hazard. Use water spray to knock-down vapors.
Stability
Stable at normal temperatures and pressures.
Incompatibilities
Incompatible with strong oxidizing and reducing agents Incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides.
Decomposition
HF, oxides of carbon.

Fire.
Upper exp. limit, %

Fire fighting
Do not extinguish fire unless flow can be stopped. Use water in flooding quantities as fog. Solid streams of water may be ineffective. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible.
Fire potential
EXTREMELY FLAMMABLE.
Hazards
Vapors from liquefied gas are initially heavier than air and spread along ground. Vapors may travel to source of ignition and flash back. Containers may explode when heated. Ruptured cylinders may rocket.

   Ingestion
Immediately obtain medical asistance.
   Inhalation
Vapors may cause dizziness or asphyxiation without warning. Some may be irritating if inhaled at high concentrations.
   Skin
Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite.
   Eyes
May cause irritation.

First aid
 
   Ingestion
Seek medical assistance.
   Inhalation
Move victim to fresh air. Apply artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult.
   Skin
Remove and isolate contaminated clothing and shoes. Clothing frozen to the skin should be thawed before being removed. In case of contact with liquefied gas, thaw frosted parts with lukewarm water
   Eyes
Flush with running water for at least 20 minutes.
