Reactivity Data
Like other metals, nickel can react with acids to liberate hydrogen gas which 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.
Toxicological Properties3
As shipped, metal foam is not inhalable. However, cutting, grinding or burning produce some dust
or fume.

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 (Group 2B). In 1997, the ACGIH categorized elemental nickel
Vale as: A5 "Not Suspected as a Human Carcinogen". Epidemiological
studies of workers exposed to nickel powder and to dust and fume
Inco 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
Material 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.
Safety 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
Data 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
LD50 produced an increased incidence of fibro sarcomas,
Sheet mesotheliomas and habdomyo sarcomas.
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.
Vale Chromium (Cr)
Inco Inhalation: Chromium metal is relatively nontoxic. Chromium metal and insoluble
salts are said to be involved in fibrosis of the lungs. When the metal is
heated to a high temperature, fumes produced may be damaging to the
lungs if inhaled.
Material The International Agency for Research on Cancer has conducted that
the evidence for carcinogenicity in humans and animals is inadequate for
chromium metal and trivalent chromium compounds, but sufficient for
hexavalent chromium compounds. Fumes from welding chromium-
Safety containing stainless steel or certain chromium-containing rods can trigger
eczematous eruptions on the palms of the hands of chromium-sensitized
individuals.
Iron (Fe)
Data Inhalation: Inhalation of the excessive oxide fumes or dusts can lead to irritation of
the respiratory tract. Prolonged inhalation of iron oxide for periods of 6 to
10 years is known to cause siderosis, which appears to be a benign
Sheet pneumoconiosis.
Eye contact: Prolonged eye contact with the metal dust could cause rust brown
colored spots forming around the particles and if left for several years,
permanent damage could result.
Preventative Measures
If user operations generate dust, mist or fume, use ventilation to keep exposure to airborne nickel
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; current
edition. 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.
