Reactivity Data
Like other metals, nickel can react with acids to liberate hydrogen gas that can form explosive
mixtures in air. Under special conditions nickel can react with carbon monoxide in reducing
atmospheres to form nickel carbonyl, Ni(CO)4, a toxic gas. Silicon can react under certain
conditions with metal acetylides, metal carbonates, metal hexafluorides, oxidants and calcium.
Toxicological Properties3
Nickel
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.
Inco 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
Material 100mg/m3 or more, were associated with excess nasal and lung
cancers.
The inhalation of nickel powder has not resulted in an increased
Safety 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
Data administered at the maximum tolerated dose. Single
intratracheal instillations of nickel powder in hamsters at doses
near the LD50 produced an increased incidence of
fibrosarcomas, mesotheliomas and rhabdomyosarcomas.
Sheet Inhalation of nickel powder at concentrations 15 times the TLV
irritated 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 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.
One case has been reported of asthma induced by external
exposure to a nickel-containing skin clip and by skin contact with
nickel.
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.
Inco Silicon
Silicon is defined by the American Conference of Governmental Industrial Hygienists as a
nuisance particulate.
Material Lead
Lead compounds tested for carcinogenicity by the International Agency for Research on Cancer
(IARC) were almost all soluble salts. Nevertheless, IARC concluded that there was sufficient
Safety evidence that lead and inorganic lead compounds were carcinogenic to animals.
Lead in all its forms is considered a cumulative poison normally entering the body by
ingestion and inhalation. Poisoning by lead can result in anemia; nervous system
disorders characterized by weakness and palsy (i.e. wrist drop); and chronic renal
Data disease.
Preventative Measures
Sheet If user operations generate dust, fume or mist, use ventilation to keep exposure to airborne
contaminants below the exposure limits. If ventilation alone cannot so control exposure, use
NIOSH-approved respirators selected according to the Selection, Care and Use of Respirators
CSA Z94.4-M1993. 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. If spilled, pick up product and replace in
original container.
Nickel-containing waste is normally collected to recover nickel values. Should waste disposal be
deemed necessary, follow the relevant governmental regulations.
First Aid Measures
If exposure to nickel carbonyl is suspected, seek medical attention immediately. For skin
rashes, seek medical attention. Cleanse wounds thoroughly to remove any particles.
