Physical Hazards
Nickel Powder Type 210 and Type 210H is a flammable metal powder. Keep away from sparks,
flames and heat. If heat-treated in a reducing atmosphere, the powder may become
spontaneously combustible.

LD50 ORAL RAT >9000 mg/kg
Inhalation: The National Toxicology Program has listed nickel as reasonably
anticipated to be a carcinogen based on the production of injection site
tumors. The International Agency for Research on Cancer (IARC) found
there was inadequate evidence that metallic nickel is carcinogenic to
humans but since there was sufficient evidence that it is carcinogenic to
animals, IARC concluded that metallic nickel is possibly carcinogenic to
humans. In 1997, the ACGIH categorized elemental nickel as: A5 "Not
Suspected as a Human Carcinogen". Epidemiological studies of workers
exposed to nickel powder and to dust and fume generated in the
production of nickel alloys and of stainless steel have not indicated the
presence of a significant respiratory cancer hazard.
Evidence for the association of nickel compound exposures and cancer
risk comes mainly from workers in now obsolete nickel refining
operations where very high concentrations of airborne nickel, mostly
present as oxidic or sub-sulphidic species at up to 100mg/m3 or more,
were associated with excess nasal and lung cancers.

The inhalation of nickel powder has not resulted in an increased
incidence of malignant lung tumors in rodents. Repeated intratracheal
instillation of nickel powder produced an increased incidence of
malignant lung tumors in rats. Repeated intratracheal instillation of nickel
powder did not produce an increased incidence of malignant lung tumors
in hamsters when administered at the maximum tolerated dose. Single
intratracheal instillations of nickel powder in hamsters at doses near the
INCO LD50 produced an increased incidence of fibrosarcomas, mesotheliomas
and rhabdomyosarcomas.
Inhalation of nickel powder at concentrations 15 times the TLV irritated
Material the respiratory tract in rodents.
Inhalation of nickel may induce asthma. This effect is rare, it has been
reported in welders where exposures to nickel are often mixed with other
Safety chemical substances. Persons with a known history of nickel sensitive
asthma should avoid such contact.
Skin Contact: Prolonged and intimate contact with metallic nickel may cause irritation
to the skin and nickel sensitivity, which may result in allergic skin rashes.
Data One case has been reported of asthma induced by external exposure to
a nickel-containing skin clip and by skin contact with nickel.
Sheet Wounds: Nickel metal powder has caused tumors at the site of injection in rodents.
However, studies do not suggest a significant risk for humans from
nickel-containing prostheses.
Ingestion: The U.S. National Institute for Occupational Safety and Health (NIOSH)
concluded there is no evidence that nickel and its inorganic compounds
are carcinogenic when ingested. The U.S. Food and Drug
Administration has affirmed that nickel is generally recognized as safe
(GRAS) as a direct human food ingredient.
Preexisting Conditions: Prolonged and intimate skin contact can cause an allergic skin rash in
previously sensitized individuals.
Reproductive Toxicity: Animal experiments indicate that soluble nickel ingestion causes adverse
effects on fetal development at a threshold oral exposure of 2.2 mg/
Ni/kg/day by pregnant rats. Data are insufficient to determine if this effect
occurs in humans and no regulatory agency has classified soluble forms
of nickel as reproductive risks for humans.
Precautions for safe storage, handling and use
Do not inhale powder. Keep container closed when not in use. Ventilation is normally required when
handling or using this product to keep exposure to airborne nickel below the exposure limit. If
ventilation alone cannot so control exposure, use NIOSH-approved respirators selected according
to OSHA 29 CFR 1910.134. Maintain airborne nickel levels as low as possible.
Avoid repeated skin contact. Wear suitable gloves. Wash skin thoroughly after handling. Launder
clothing and gloves as needed.
Do not store near acids or reactive substances. Do not expose to heat. Under special conditions
nickel can react with carbon monoxide in reducing atmospheres to form nickel carbonyl, Ni(CO)4, a
toxic gas.

Spill, leak and disposal procedure
If spilled, collect spills by wet sweeping or by vacuuming with the vacuum exhaust passing through
a high efficiency particulate arresting (HEPA) filter if the exhaust is discharged into the workplace.
Wear appropriate NIOSH-approved respirators if collection and disposal of spills is likely to cause
the concentration of airborne contaminants to exceed the exposure limits.
INCO Nickel-containing waste is normally collected to recover nickel values. Should waste disposal be
deemed necessary, follow EPA and local regulations.
Material Emergency and first aid procedures
If exposure to nickel carbonyl is suspected, seek medical attention immediately. For skin rashes,
seek medical attention. Cleanse wounds thoroughly to remove any particles. If powder is ignited,
Safety extinguish fires with normal wet methods and keep containers cool with water spray.
