Hazards and Protection.
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.
Protection
Wear appropriate protective gloves, clothing and goggles.
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.
Stability
No data.
Incompatibilities
Explodes when heated to about 60C Reacts explosively with bromine (liquid), oxygen in the presence of mercury, or hydrocarbons (butane) mixed with oxygen Reacts with tetrachloropropadiene to form an extremely explosive dinickel chloride dimer.

Fire fighting
Material is too dangerous to health to expose fire fighters. A few whiffs of the vapor could cause death. If liquid or vapor penetrates fire fighter's protective gear it will cause fatality. Normal full protective gear available to the average fire department will not provide adequate inhalation or skin protection.Use water, alcohol foam, carbon dioxide, dry chemical. Use water in flooding quantities as fog. Solid streams of water may be ineffective.
Fire potential
HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames.
Hazards
Vapor forms explosive mixtures with air. Vapor is heavier than air and may travel a considerable distance to source of ignition and flash back. Liquid may explode when heated under confinement. Vapor explosion and poison hazard indoors, outdoors, or in sewers. Runoff to sewer may create fire and explosion. May explode at 68F in presence of air or oxygen. Avoid contact with heat, acid or acid fumes as these cause the emission of highly toxic fumes. Avoid contact with air, ignition sources and vapors entering a confined space.
Combustion products
Toxic gases formed by incomplete combustion.

Exposure effects
Rapid breathing is a delayed effect. Fever and rapid heart rate have been reported. CNS depression, with headache, nausea, dizziness, weakness, paresthesias, irrational thoughts, insomnia and rarely seizures may occur. In humans, no adverse reproductive effects or birth defects following exposure have been described. No data were available evaluating the effects of exposure from breast-feeding. <br>In animals, eye and ear abnormalities have been described in offspring following gestational exposure. Other defects observed following exposure during pregnancy include cleft palate, exencephaly and cystic lungs. Other animal studies describe fetal death, fetotoxicity, decreased litter size and decreased neonatal growth. Following exposure of dams prior to mating resulted in decreased fertility in the male offspring.
   Ingestion
See inhalation.
   Inhalation
Severe pulmonary irritation, dyspnea, retrosternal pain, pneumonitis and potentially fatal non-cardiogenic pulmonary edema may occur. The exhaled breath may smell like soot. Asthma has been reported.
   Skin
Severe irritation, dermatitis, burns and/or diaphoresis may occur. Cyanosis can develop.
   Eyes
See inhalation.

First aid
 
   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. Remove and isolate contaminated clothing and shoes.
   Skin
Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush with running water for at least 20 minutes. Wash skin with soap and water.
   Eyes
In case of contact with substance, immediately flush with running water for at least 20 minutes.
