5. Fire Fighting Measures
Suitable extinguishing media: Package intact - Any, type to be selected according to materials stored in the
immediate neighborhood. Spilled Powder 鈥? Use water mist or fine spray -
pressurized extinguishants may disperse the powder and spread the fire.

Special protective equipment None needed. Wear protective equipment if required for other materials
for fire fighting: within the immediate vicinity
6. Accidental Release Measures
Person related precautionary Avoid generation of dusty atmospheres. Do not inhale dusts.
measures:
Environmental protection No specific measures needed
measures:
Procedures for cleaning/ Collect spills by wet sweeping or vacuuming with the vacuum exhaust
INCO
absorption: passing through a high efficiency particulate arresting (HEPA) filter if exhaust
is discharged into the work place. Wear appropriate nationally approved
respirators if collection and disposal of spills is likely to cause the
concentration limits of airborne nickel to exceed the locally prescribed
exposure limits. Nickel containing material is normally collected to recover
Material nickel values.
7. Handling and Storage
Safety Handling: Prevent the generation of inhalable dusts e.g. by the use of suitable
ventilation. Do not inhale dusts. Wear appropriate nationally approved
respirators if handling is likely to cause the concentration limits of airborne
nickel to exceed the locally prescribed exposure limits. Wear suitable
protective clothing and gloves. As packed nickel product may constitute a
Data manual handling risk.
Storage: Keep in the container supplied, in dry conditions and keep the container
closed when not in use. Containers should be stored under cover in a clean
and dry environment. Local regulations should be followed regarding the
Sheet storage of this material.
8. Exposure Controls/Personal Protection
Exposure limit values: Occupational exposure limits expressed as Ni in inhalable particle size
fraction:
TRK (mg/m3*) TLV (mg/m3*) WEL (mg/m3*)
0.5 1.5 0.5
Maintain airborne nickel levels as low as possible.
Occupational exposure Ventilation is normally required when handling or using this product to keep
controls: airborne nickel below the nationally authorized limits. If ventilation alone
cannot control exposure, respiratory protection must be used.
a) Respiratory protection: Do not inhale dust. If ventilation alone cannot control exposure, respiratory
protection (selected specifically for the working place, depending on
concentration and quantity of the hazardous material) must be used.
b) Eye protection: Avoid contact with eyes. Wear goggles or face shield or approved safety
glasses.
c) Hand and skin protection: Avoid skin contact. Wear suitable protective clothing and gloves, which
should be selected specifically for the working place, dependant on the
concentration and quantity of the hazardous material being handled. Wash
skin thoroughly after handling and before eating, drinking or smoking.
Launder clothing and gloves as needed. Use of skin protective barrier cream
advised.

10. Stability and Reactivity
Sheet Conditions to be avoided: Hazardous exothermic reaction improbable. Not classified as flammable.
Substances to be avoided: This product can react vigorously with acids to liberate hydrogen, which can
form explosive mixtures with air. Under special conditions nickel can react
with carbon monoxide in reducing atmospheres to form Nickel Carbonyl,
Ni(CO)4 , a toxic gas. Metal powders when heated in reducing atmospheres
may become pyrophoric.
Hazardous decomposition None

11. Toxicological Information
Acute Toxicity:
a) Oral: Non toxic - LD50 ORAL RAT >9000 mg/kg
The U.S. Food and Drug Administration (FDA) has affirmed that nickel is
generally regarded as safe (GRAS) as a direct human food ingredient.
b) Inhalation: One case has been reported of a fatality following extreme exposure at an
estimated 382 mg Ni/m3. A plasma spraying operative died of pneumonia 13
days after exposure to nickel powder particles. The post mortem diagnosis
was shock lung.
c) Dermal: No information available.
Corrosivity / Irritation:
a) Respiratory Tract: None
b) Skin: Nickel metal is a well known skin sensitizer. Direct and prolonged skin
Updated 05/06
contact with metallic nickel may induce nickel allergy and elicit nickel allergic
Page 3 of 5
skin reactions in those people already sensitized to nickel, so called nickel
allergic contact dermatitis.
c) Eyes: Mechanical irritation may be expected.
d)Preexisting conditions: Individuals known to be allergic to nickel should avoid contact with nickel
whenever possible to reduce the likelihood of nickel allergic contact
dermatitis reactions (skin rashes). Repeated contact may result in persistent
chronic palmar/hand dermatitis in a small number of individuals, despite
efforts to reduce or avoid nickel exposure.
Sensitization:
a) Respiratory tract: Nickel metal induced asthma is very rare. 3 case reports are available; the
INCO data is not sufficient to conclude that nickel metal is classified as a
respiratory sensitizer.
b) Skin: Nickel metal is a potent skin sensitiser. Repeated /prolonged contact with
Material metallic nickel may cause nickel sensitivity resulting in skin allergy. Persons
with a known history of eczema or nickel dermatitis should avoid such
contact.
Repeated dose toxicity:
Safety a) Oral: No information available
b) Inhalation: Animal studies (rats) show that repeated dose inhalation of nickel damages
the lung. Chronic inflammation, lung fibrosis and accumulation of nickel
particles were observed.
Data c) Dermal: Direct and prolonged contact with nickel metal may cause nickel sensitivity
resulting in skin allergy.
Mutagenicity /
Sheet Reproductive toxicity: No data.
Carcinogencity:
a) Ingestion: The U.S. National Institute for Occupational Safety and Health (NIOSH)
concluded that there is no evidence that nickel metal is carcinogenic when
ingested.
b) Inhalation: There is limited information available from inhalation and intratracheal
studies in animals. To date, there is no evidence that nickel metal causes
cancer in humans based on epidemiology data from workers in the nickel
producing and nickel consuming industries.
c) Injection: Implants and injections of nickel metal in animals have produced tumors at
the local sites. IARC (1999) concluded that there is sufficient evidence in
experimental animals for the carcinogenicity of metallic nickel implants and
for nickel alloy powder containing ~66% Ni 13-16% chromium and 7% for
nickel alloy powder iron.
