Inhalation: Evidence for the association of nickel compound exposures and
cancer risk comes mainly from workers in now obsolete nickel
refining operations. The studies of nickel workers suggest that
respiratory cancer risks are primarily related to exposure to
relatively insoluble forms of nickel notably sulphidic and oxidic
nickel at concentrations greater than 10mg/m3. Toxic respiratory
effects in animals may be caused by reduced particle clearance
capacity.

The International Agency for Research on Cancer (IARC) (ref. 4)
in 1990 and the U.S. Tenth Report on Carcinogens (ref. 5) in 2002
concluded there was sufficient evidence that nickel compounds
are carcinogenic to humans. The Report of the International
Committee on Nickel Carcinogenesis in Man reported that
workers who have been primarily exposed to nickel oxide
showed some evidence of increased lung cancer.
Inco
The European Union Commission in 1991 classified nickel oxide
and work involving exposure to dusts, fumes and sprays
Material produced during the roasting and electrorefining of nickel-copper
mattes as carcinogenic processes.
ACGIH has re-evaluated the data regarding the carcinogenicity
Safety of nickel and nickel compounds and has classified nickel oxide
as a confirmed human carcinogen, Class A1.
There is some evidence that the inhalation of nickel oxide has
resulted in an increased incidence of malignant lung tumors in
Data rats. Inhalation of nickel oxide at concentrations 50 times the
TLV, produced pneumoconiosis in hamsters. Repeated
intratracheal instillation of nickel oxide produced an increased
incidence of malignant lung tumors in rats.
Sheet Wounds: Nickel oxide has caused tumors at the site of injection in rodents.
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: There is no evidence of mutagenesis. 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.

Preventative Measures
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 oxide
below the exposure limit. If ventilation alone cannot so control exposure, use
NIOSH-approved respirators selected according to the Selection, Care and Use of
Respirators CSA Z94.4-M1982. Maintain the airborne nickel levels as low as possible.

If spilled, collect spills by wet sweeping or by vacuuming and pass the vacuum exhaust
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 the relevant governmental regulations.
Material First Aid Measures
For inhalation irritation, move to fresh air and seek medical attention. For skin irritation, wash
skin thoroughly with plenty of water; seek medical attention. For eye contact, immediately flush
Safety eyeballs with plenty of water; seek medical attention. Cleanse wounds thoroughly to remove any
particles.
