Hazards and Protection.
Storage
Store in a cool, dry place. Store in a tightly closed container.
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
Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk. Cover with plastic sheet to prevent spreading. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. DO NOT GET WATER INSIDE CONTAINERS.
Stability
Stable under normal temperatures and pressures.
Incompatibilities
Peroxides.
Decomposition
Hydrogen fluoride, nickel oxide.

Fire.
Fire fighting
Use method most appropriate to fight surrounding fire.
Fire potential
Non-Combustible
Combustion products
Toxic gases and vapors (such as nickel carbonyl) may be released in a fire involving nickel.

Health.
Exposure limit(s)
IDHL: NIOSH considers nickel metal and other compounds (as Ni) to be a potential
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. Hyperactive reflexes, painful muscle spasms, weakness and tetanic contractures may be noted due to fluoride induced hypocalcemia. Prenatal fluoride supplementation (2.2 mg NaF or 1 mg fluoride daily) during the last two trimesters of pregnancy has been reported to be safe.
   Ingestion
Epigastric pain, nausea, dysphagia, salivation, hematemesis, and diarrhea may be noted. These effects may be delayed for several hours following exposure. Gi symptoms are noted when 3 to 5 mg/kg of fluoride are ingested.
   Inhalation
Respirations are first stimulated then depressed. Death is usually from respiratory paralysis. Following inhalation, coughing and choking may be noted.
   Skin
Urticaria and pruritus have been reported following exposure to fluoride.
   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.
   Skin
Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician should examine the area if irritation or pain persists.
   Eyes
Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility.
