Hazards and Protection.
Storage
Storage temp: ambient hexahydrate
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
Skin protection and filter mask recommended. Heat may necessitate use of self-contained breathing apparatus.
Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).
Small spills/leaks
Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Land spill: Dig a pit, pond, lagoon, holding area to contain liquid or solid material. Cover solids with a plastic sheet to prevent dissolving in rain or fire fighting water. Water spill: Neutralize with agricultural lime (CaO), crushed limestone (CaCO3), or sodium bicarbonate (NaHCO3). Adjust pH to neutral (pH=7). Use mechanical dredges or lifts to remove immobilized masses of pollutants and precipitates.
Stability
No data.
Decomposition
When heated to decomposition, emits toxic fumes of nitrogen oxides, sulfur oxides and nickel. Decomposition by heat hexahydrate toxic gases and vapors (such as nickel carbonyl) may be released.

Fire.
Fire fighting
Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.)
Fire potential
Can release nh3 gas. Moderate hazard.
Hazards
Containers may explode when heated.
Combustion products
Toxic oxides of nitrogen may be formed in fire.

Exposure limit(s)
TLV (as Ni): ppm; 0.05 mg/m3 (ACGIH 1990-1991).
Carcinogin
G-A4, I-1, N-1, CP65
Exposure effects
Acute intoxication of nickel carbonyl has two stages, immediate and delayed. A person may have a temperature as a delayed symptom, but it will seldom elevate above 101 degrees. Early symptoms after inhalation are dizziness, giddiness, and weakness. Nickel salts are reported to be animal teratogens. Increased incidence of stillbirth and neonatal mortality of rat offspring were associated with maternal consumption of nickel chloride solutions prior to mating and during gestation. Nickel has been found in breast milk. ORAL ADMINISTRATION of nickel sulphate to rats caused decreased testicular, prostate, and seminal vesicle size as well as abnormalities of sperm and decreased sperm count.
   Ingestion
Large doses taken orally or by inhalation may cause nausea, vomiting, and diarrhea.
   Inhalation
Inhalation of material may be harmful.
   Skin
Contact may cause burns.
   Eyes
See Skin.

First aid
 
   Ingestion
The possible benefit of early removal of some ingested material by cautious gastric lavage must be weighed against potential complications of bleeding or perforation. Activated charcoal activated charcoal binds most toxic agents and can decrease their systemic absorption if administered soon after ingestion. Activated charcoal: administer charcoal as a slurry (240 ml water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents.
   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. Immediately flush with running water for at least 20 minutes.
   Eyes
Immediately flush with running water for at least 20 minutes.
