Physical Hazards
Sheet Fire or Explosion Hazard
As supplied this product does not present a fire or explosion hazard. However, magnesium vapor
liberated in the use of this product (eg. production ductile iron) in contact with air at elevated
temperatures can result in a violent explosion.
Also, finely-divided magnesium in the use of this product in contact with air at temperatures near the
melting point of magnesium will ignite and burn with a white flame. Magnesium fires should be
smothered with dry graphite or other suitable dry powders. (Consult National Fire Protection
Association (NFPA) standards to determine suitable extinguishing media applicable to user
operations.) Do not use foam, carbon tetrachloride, or carbon dioxide. Use of water can produce
hydrogen gas and result in an explosion. Avoid direct viewing of magnesium fires to prevent eye
injury.
In magnesium fire conditions, protect eyes and skin against flying particles. A build-up of
finely-divided magnesium from the use of this product should be prevented. If clean-up is
necessary, see Spill, Leak and Disposal Procedure.
Health Hazards
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.
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.
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
INCO 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 fibrosarcomas,
Material mesotheliomas and rhabdomyosarcomas.
Inhalation of nickel powder at concentrations 15 times the PEL
irritated the respiratory tract in rodents.
Safety In 1997, the ACGIH categorized elemental nickel as: A5 "Not
Suspected as a Human Carcinogen."
Skin Contact: Prolonged and intimate contact with metallic nickel may cause
Data irritation to the skin and nickel sensitivity which may result in
allergic skin rashes.
One case has been reported of asthma induced by external
Sheet 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.
Magnesium
Wounds: Magnesium powder and magnesium alloy have caused necrotic
gaseous tumors at the site of subcutaneous injection in
experimental animals. No similar experiences have been reported
in humans.
Open skin abrasions and wounds exposed to magnesium metal
may be difficult to heal.
Ingestion: The lowest lethal dose of magnesium (LDLo) is 230 mg/kg in dogs.
Precautions for safe storage, handling and use
If user operations generate dust, fume or mist, use ventilation to keep exposure to airborne nickel
and magnesium oxide below the PELs4. 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. This product can react vigorously with acids to liberate hydrogen gas
which can form explosive mixtures in air.
INCO 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
Material 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 EPA and local
regulations.
Safety If clean-up of finely-divided magnesium arising from the use of this product is required, use
non-sparking tools to prevent ignition. Do not vacuum. Carefully sweep up and store in tightly
closed metal or fibre containers. Protect containers against physical damage. Store in a detached
fire resistive building, protected from moisture and away from reactive substances such as chlorine,
Data bromine, iodine, acids and all possible sources of ignition.
Emergency and first aid procedures
If exposure to nickel carbonyl is suspected, seek medical attention immediately. For skin rashes,
Sheet seek medical attention. Cleanse wounds thoroughly to remove any particles.
