Hazards and Protection.
Storage
Store at sealed containers in well-ventilated area at ambient temperature.
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 material out of water sources and sewers.
Stability
No data.
Incompatibilities
Heating magnesium with nickel cyanide causes the magnesium to become incandescent.
Decomposition
When heated to decomposition it emits very toxic fumes of hydrogen cyanide. 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 water in flooding quantities as fog. Use foam, dry chemical, or carbon dioxide.
Fire potential
Not flammable
Combustion products
Toxic gases and vapors (such as nickel carbonyl) may be released in a fire involving nickel.

Health.
Exposure limit(s)
TLV (as CN): ppm; 5 mg/m3 (skin) (ACGIH 1991-1992).
Carcinogin
G-A1, 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. Initially, headache, vertigo, and agitation occur, followed by combative behavior, coma, seizures, and death. 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
Tachypnea, hyperpnea, and dyspnea followed rapidly by respiratory depression are common. Pulmonary edema may occur.
   Skin
Papules, rashes, pruritus, and ulcerations may occur.
   Eyes
Burning sensation of mouth and throat, and equally red retinal arteries and veins are common.

First aid
 
   Ingestion
CYANIDES ARE EXTREMELY TOXIC AND FAST-ACTING POISONS. Even though the induction of vomiting is not usually recommended outside of a physician's care if the victim is conscious and not convulsing, it may be worth the risk if a cyanide has been ingested. Ipecac syrup or salt water may be used to induce vomiting in such an emergency. IMMEDIATELY call a hospital or poison control center and transport the victim to a hospital. If the victim is convulsing or unconscious, do not give anything by mouth, assure that the victim's airway is open and lay the victim on his/her side with the head lower than the body. DO NOT INDUCE VOMITING. IMMEDIATELY transport the victim to a hospital.
   Inhalation
IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. IMMEDIATELY call a physician and be prepared to transport the victim to a hospital even if no symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used.
   Skin
IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment.
   Eyes
First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.
