Hazards and Protection.
Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage.
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Wear appropriate protective gloves, clothing and goggles -- as recommended by the manufacturer. Always wear thermal protective clothing when handling refrigerated/cryogenic liquids.
Wear positive pressure self-contained breathing apparatus (SCBA).
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.
Incompatible with acids, alcohols, amines, and aldehydes.
The substance may spontaneously ignite on contact with air. Decomposes on heating above 350 C and on contact with oxidizers, such as nitric acid.
Do not extinguish fire unless flow can be stopped. Use water in flooding quantities as fog. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Solid streams of water may be ineffective. Use foam, dry chemical, or carbon dioxide.
Flammable; may be ignited by heat, sparks or flames. May form explosive mixtures with air.
Flammable; may be ignited by heat, sparks or flames. May form explosive mixtures with air. May polymerize explosively when heated or involved in a fire. Vapors from liquefied gas are initially heavier than air and spread along ground. Vapors may travel to source of ignition and flash back. Some of these materials may react violently with water. Containers may explode when heated. Ruptured cylinders may rocket. Runoff may create fire or explosion hazard.
Fire will produce irritating, corrosive and/or toxic gases.
NIOSH REL: TWA 0.2 ppm (0.6 mg/m3)
The toxological properties of this substance have not been fully investigated.
May be toxic/fatal if inhaled. Contact may cause burns, severe injury and/or frostbite.
May be toxic/fatal if absorbed through skin. Contact may cause burns, severe injury and/or frostbite.
Contact may cause burns, severe injury and/or frostbite.
Seek medical assistance.
Move victim to fresh air. Apply artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult.
Remove and isolate contaminated clothing and shoes. Immediately flush with running water for at least 20 minutes. In case of contact with liquefied gas, thaw frosted parts with lukewarm water.
Immediately flush with running water for at least 20 minutes.
