Hazards and Protection.
Storage
Use ambient storage temperature and open venting. Keep well closed.
Handling
Containers of this material may be hazardous when emptied. Since emptied containers retain product residues (vapor, liquid, and/or solid), all hazard precautions given in the data sheet must be observed.
Protection
Goggles or face shield; protective gloves; bureau of mines approved respirator; protective clothing.
Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).
Small spills/leaks
Keep material out of water sources and sewers. Apply water spray or mist to knock down vapors. Disperse vapors using fans or blowers. 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. Neutralize with sodium bisulfate (NaHSO4). Water spill: Add sodium sulfate (Na2SO4). Neutralize with dilute acid. Use natural deep water pockets, excavated lagoons, or sand bag barriers to trap material at bottom. Neutralize with agricultural lime (CaO), crushed limestone (CaCO3), or sodium bicarbonate (NaHCO3). Add sodium bisulfate (NaHSO4).
Stability
No data.
Incompatibilities
Reacts violent with potassium.
Decomposition
When heated to decomposition it emits very toxic fumes of hydrogen chloride. 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.) Use foam, dry chemical, or carbon dioxide. Keep run-off water out of sewers and water sources.
Fire potential
Nonflammable
Hazards
Containers may explode when heated. Runoff may pollute waterways.
Combustion products
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes.

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
Highly toxic, may be fatal if inhaled, swallowed or absorbed through skin. Effects of contact or inhalation may be delayed.
   Skin
Avoid any skin contact. See Inhalation.
   Eyes
See Inhalation.

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. 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.
   Skin
Remove and isolate contaminated clothing and shoes. Remove material from skin immediately. Immediately flush with running water for at least 20 minutes. For minor skin contact, avoid spreading material on unaffected skin.
   Eyes
Immediately flush with running water for at least 20 minutes.
