First Aid Measures

Ingestion

Seek medical assistance.

Inhalation

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. Effects may be delayed.

Skin

IRemove and isolate contaminated clothing and shoes.. n case of contact with liquefied gas, thaw frosted parts with lukewarm water Immediately flush skin with running water for at least 20 minutes. Effects may be delayed.

Eyes

In case of contact with liquefied gas, thaw frosted parts with lukewarm water Immediately flush skin with running water for at least 20 minutes.

Handling and Storage

Storage

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.

Handling

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.

Hazards Identification

Inhalation

Vapors are extremely irritating and corrosive.

Skin

Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite.

Eyes

See Skin.

Hazards

Container may explode in heat of fire. When heated to decomposition, it emits very toxic fumes of fluorides and sulfur oxides. Reacts violently with water. It is decomposed by concentrated sulfuric acid. Thermostable to 1112F.

Fire Fighting Measures

Fire Fighting

Keep unnecessary people away; isolate hazard area and deny entry. Stay upwind; keep out of low areas. Ventilate closed spaces before entering them. Wear positive pressure breathing apparatus and full protective clothing. Evacuate area endangered by gas.This material is non-combustible. Small fires: dry chemical or carbon dioxide. Large fires: water spray, fog or foam. Do not get water inside container. Move container from fire area if you can do so without risk. Stay away from ends of tanks. Spray cooling water on containers that are exposed to flames until well after fire is out. Isolate area until gas has dispersed.

Accidental Release Measures

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 and Reactivity

Incompatibilities

Keep away from concentrated sulfuric acid, dioxygen difluoride. Readily hydrolyzed by moisture, forming hydrofluoric acid & thionyl fluoride.

Stability

No data.
