Section 6 - Health Hazard Data
Note: Products in their usual physical form do not pose any health hazards. However, operations such as burning, welding, sawing, brazing, or grinding
may result in the following effects if exposures exceed permissible limits.
Route(s) of Entry: Inhalation: Yes Skin Contact: Yes Eye Contact: Yes Ingestion: No
Health Hazards:
Acute: Excess exposure to all metallic fumes and dusts may result in irritation of eyes nose and throat. Also high concentrations of fumes and dusts of
iron-oxide, manganese and copper may result in metal fume fever.
Chronic: Chronic and prolonged inhalation of high concentrations of fumes or dust of the following elements may lead to the conditions listed opposite
the element:
Aluminum May initiate fibrotic changes to lung tissue, irritation of the eyes, nose and throat. Particles Al deposited in the eye may cause irreversible
tissue damage of the cornea. Al salts may cause dermatitis, eczema, conjunctivitis and irritation of the mucus membranes of the upper
respiratory tract. Long-term inhalation exposure to Al dusts or fumes has been associated with a fibrotic lung condition known as
Shaver's disease. Al dust/fines and fumes are a low health risk by inhalation. For standard operations (milling, cutting, grinding),
aluminum dust should be treated as a nuisance dust as defined by the ACGIH. Welding aluminum, plasma arc cutting, and arc spray
metalizing can generate ozone. Excessive exposure to aluminum fume and dust has been associated with lung disease, but this effect is
probably due to simultaneous silica exposure.
Carcinogenicity: N/A NTP? No IARC? A4* OSHA Regulated? No
*(for aluminum oxide)
Beryllium Be can cause irritant dermatitis, hypersensitivity dermatitis, skin granulomas and allergic contact dermatitis. Be is also a suspected
human carcinogen and has caused cancer in laboratory animals. Inhalation of excessive levels of Be dust and fumes can result in acute
pneumonitis (inflammation of lung tissues). Chronic inhalation above permissible limits can produce chronic berylliosis (progressive lung
disease) and systemic beryllium disease. Granulmatos lesions of the skin, liver, kidneys, spleen, and lymph nodes have been reported.
Damage to the lungs can be in both the acute and chronic forms, both of which have similar signs and symptoms. These include a
relatively non-productive cough, progressive difficulty in breathing, loss of appetite, and loss of weight. The major difference between the
two is the suddenness of onset and the rate of progression. In the acute form, the symptoms appear in several hours to several weeks
after exposure and there is usually rapid progression of signs including dyspnea, anorexia, and extreme weight loss. Complete recovery
is possible and fatal cases usually result from acute heart disease. In chronic beryllium disease, the symptoms or signs are generally
delayed in their onset and are persistent in nature. They may be triggered or aggravated by stresses such as pregnancy, respiratory
infection, and thyrotoxicosis. In the progression of the disease, symptoms of heart disease may occur. Inhalation of beryllium has
produced multiple site tumors (lung tumors) in animal studies and is a suspected human carcinogen. Beryllium is listed on the NTP and
is listed as carcinogenic to humans by IARC.
Carcinogenicity: Yes NTP? 2 IARC? A2* OSHA Regulated? No
*(ACGIH has published notice of intended change to A1)
Chromium Cr fumes and dusts can cause sensitization dermatitis, inflammation and/or ulceration of upper respiratory tract, lesions of the skin and
mucus membranes, and possibly cancer of the nasal passages or lungs-bronchogenic carcinoma.
Carcinogenicity: N/A NTP? No IARC? A4 OSHA Regulated? No
Hexavalent Chrome VI can cause asthma, kidney damage, primary irritant dermatitis, sensitization dermatitis, skin ulceration, and pulmonary edema
Chromium (fluid in the lungs). Chronic inhalation or overexposure has been associated with lung, nasal, and gastrointestinal cancer. Hexavalent
(ChromeVI) chromium is listed as carcinogenic to humans by IARC. Chromium and some of its compounds are listed as carcinogenic by the NTP.
Carcinogenicity: Yes NTP? 1 IARC? A1 OSHA Regulated? No
Cobalt Inhalation of Co dust may cause an asthma-like disease with cough and dyspenea, respiratory tract irritation and hypersensitization
dermititis. Chronic overexposure to Co dust and fume may result in polythemia, hyperplasia of bone marrow and thyroid gland,
pericardial effusion and damage to pancreas alpha cells. Animal studies have shown that particulate is an acutely irritating substance
and industrial exposures, possibly combined with small amounts of silica, are reported capable of producing serious pneumoconiosis
which is initially of an insidious nature.
Carcinogenicity: N/A NTP? No IARC? A3 OSHA Regulated? No
Copper No chronic debilitating symptoms indicated. Inhalation of Cu dusts, fumes and mists may cause irritation of the eyes, nose and throat
and a flu-like illness called metal fume fever. Early symptoms of metal fume fever include a metallic or sweet taste in the mouth, dryness
and irritation of the throat and coughing. These symptoms may progress to shortness of breath, headache, fever, chills, muscle aches,
nausea, vomiting, weakness, fatigue and profuse sweating. The attack may last 6-48 hours and is more likely to occur after a period
away from the job. Chronic overexposure to copper fumes may result in blood disorders (anemia) . Repeated or prolonged exposure to
Cu fumes may cause discoloration of hair, hands, and soles of the feet (keratinization).
Carcinogenicity: N/A NTP? No IARC? No OSHA Regulated? No
Iron No chronic debilitating symptoms indicated. Subjecting Fe and alloys containing Fe to high temperatures (such as occurs during
welding) will cause the formation of iron oxide. High exposures to iron oxide dust or fumes can cause x-ray changes (siderosis or iron
pigmentation) in the lungs as a result of long-term exposure. Siderosis is a benign condition and is not associated with pulmonary
fibrosis (scarring of the lung). Ingestion of high levels of iron oxide can cause gastrointestinal irritation, bleeding and systemic toxicity.
Carcinogenicity: N/A NTP? No IARC? A4* OSHA Regulated? No
*(for iron oxide)
Lead Lead is an accumulated poison. Inhalation effects of exposure to fumes or dust of inorganic lead may not develop quickly. Symptoms
may include decreased physical fitness, fatigue, sleep disturbance, headache, aching bones and muscles, constipation, abdominal pains
and decreasing appetite. The effects are reversible and complete recovery is possible. Inhalation of large amounts of lead may lead to
seizures, coma and death. Chronic or acute inhalation exposures to the fumes or dusts of inorganic lead compounds (such as lead
oxide) can adversely affect several organ systems including the nervous system, the gastrointestinal system, the hematological system
and renal system. The early effects are characterized by fatigue, constipation, muscle aches, abdominal pains, and decreased appetite.
Later signs and symptoms can include anemia, pallor, a "lead Line" on the gums, and reduced hand-grip strength. Lead colic produces
intense abdominal cramping which can be accompanied by constipation, nausea, and vomiting. A condition called "wrist drop" can
develop if the peripheral nervous system is affected. Severe central nervous system effects (referred to as lead encephalopathy) usually
only occur after heavy and rapid lead exposures. Signs and symptoms may include headache, dizziness, convulsions, delirium, coma,
and possibly death. Long-term exposures can also produce kidney damage with possible decreased renal function leading to such
conditions called stannosis. Alcohol ingestion and physical exertion may bring on symptoms. Continued exposure can result in
decreased fertility and/or increased chances of miscarriage or birth defects. Lead inorganic dust and fume is listed as possibly
carcinogenic by IARC.
Carcinogenicity: N/A NTP? No IARC? A3 OSHA Regulated? No
Lead Anemia, urinary dysfunction, weakness, constipation, nausea, nervous disorder, peripheral neuropathy and chromosomal changes.
chromate Carcinogenicity: Yes NTP? No IARC? A2 OSHA Regulated? No
Magnesium Magnesium oxide fumes can cause upper respiratory tract irritation and metal fume fever. Temporary symptoms can include fever,
chills, nausea, vomiting and muscular pain.
Carcinogenicity: N/A NTP? No IARC? No OSHA Regulated? No
Manganese Mn intoxication is usually due to the oxide or salts of Mn, elemental Mn exhibits very low toxicity. Manganese oxide fumes can act as
minor irritants to the eyes and respiratory tract and metal fume fever. Both acute and chronic exposures may adversely affect the central
nervous system (manganism), pneumontitis (inflammation of lung tissue), and may cause fibrosis (scarring of lung tissue). and
reproductive disorders (impotence) in males. Early symptoms may include weakness in lower extremities, sleepiness, salivation,
nervousness and apathy. Bronchitis, pneumontiis, lack of coordination resembling Parkinson's disease (apathy, weakness, etc.). The
central nervous system is the chief site of the injury, and there may be adverse blood and kidney effects. Chronic manganese poisoning
is not a fatal disease although it is extremely disabling. Some individuals may be hypersusceptible to manganese. Freshly formed
manganese fume has caused fever and chills similar to metal fume fever.
Carcinogenicity: N/A NTP? No IARC? No OSHA Regulated? No
Nickel Skin contact with nickel and its compounds may cause allergic dermatitis. The resulting skin rash is often referred to as "nickel itch,"
which usually occurs when the skin is moist. Ni metal is listed as a possibly carcinogenic to humans by IARC. Ni fumes and dusts can
cause skin sensitization and allergic contact dermatitis. Ni and its compounds may also produce eye irritation, particularly on the inner
surfaces of the eyelids (i.e. the conjunctiva).Chronic inhalation of high levels of Ni can cause irritation of airways and lungs, lung fibrosis
(scarring of the lungs), nasal septum perforation, nasal sinusitis, respiratory sensitization and asthma. Ni compounds have caused
cancer of the lungs, larynx, and paranasal sinuses in lab animals
Carcinogenicity: Yes NTP? 2 IARC? No* OSHA Regulated? No
*(ACGIH has published notice of intended change to A4 for soluble and A1 for insoluble compounds)
Nitrogen Oxides of nitrogen can cause irritation of the eyes, skin (when moist), and upper respiratory tract. Exposure to high levels of nitrogen
oxides can cause delayed pulmonary edema (fluid in the lungs) which may be fatal. Nitric oxide can cause formation of methemoglobin
which decreases the blood's ability to carry oxygen. Chronic overexposure can cause pulmonary fibrosis (scarring of the lungs).
Carcinogenicity: N/A NTP? No IARC? No OSHA Regulated? No
Oil coating Some products are supplied with an oil coating or have residual oil from the manufacturing process. Prolonged or repeated skin contact
with oil may result in skin irritation, dermatitis, or both. Untreated mildly refined mineral oils have produced skin tumors on repeated
applications to laboratory animals. They are listed as carcinogenic on the NTP and IARC. If the product is heated well above the ambient
temperatures or machined, oil vapor or mist may be generated. Overexposure to oil mist or vapor may cause asthma, bronchitis,
respiratory tract irritation and neurological effects such as headaches, dizziness, drowsiness and central nervous system depression.
Carcinogenicity: N/A NTP? No IARC? No* OSHA Regulated? No
*(ACGIH has published notice of intended change to A1 for oils containing a total of 15 polynuclear aromatic hydrocarbons (PAH's) listed
as carcinogens by the U.S. NTP)
Oxygen Oxygen can cause irritation of the eyes, skin (when moist), and upper respiratory tract. Exposure to high levels of nitrogen oxides can
cause delayed pulmonary edema (fluid in the lungs) which may be fatal. Nitric oxide can cause formation of methemoglobin which
decreases the blood's ability to carry oxygen. Chronic overexposure can cause pulmonary fibrosis (scarring of the lungs).
Carcinogenicity: N/A NTP? No IARC? No OSHA Regulated? No
Ozone Overexposure to ozone can result in mucus membrane and respiratory tract irritation. Severe overexposures can cause pulmonary
edema (fluid in the lungs).
Carcinogenicity: N/A NTP? No IARC? No OSHA Regulated? No
Silicon No chronic debilitating symptoms indicated. Chronic exposure to inert dusts of silicon can cause increased airways resistance and
contribute to chronic bronchitis. Accumulation in lungs may be responsible for benign pneumoniosis, but is not considered to be
responsible for pulmonary functional impairment or respiratory symptoms. Intracheal administration of silicon in rabbits produced
significant pulmonary lesions.
Carcinogenicity: N/A NTP? No IARC? No OSHA Regulated? No
Tin The toxicity of inorganic tin compounds is generally low. Chronic high level exposure to the dust or fumes of tin oxides can result in a
benign pneumoconiosis called stannosis, which is reported not to be disabling. No tissue reaction or pulmonary dysfunction has been
associated with this lung condition.
Carcinogenicity: N/A NTP? No IARC? No OSHA Regulated? No
Welding Welding fumes cannot be classified simply. The composition and quantity of both are dependent on the alloy being welded and the
fumes process and electrodes used. Reliable analysis of fumes cannot be made without considering the nature of the welding process and
system being examined; reactive metals and alloys such as aluminum and titanium are arc-welded in a protective, inert atmosphere such
as argon. These arcs create relatively little fume, but they do create an intense radiation which can produce ozone. Similar processes
are used to arc-weld steels, also creating a relatively low level of fumes. Ferrous alloys also are arc-welded in oxidizing environments
that generate considerable fume and can produce carbon monoxide instead of ozone. Such fumes generally are composed of discrete
particles of amorphous slags containing iron, manganese, silicon, and other metallic constituents depending on the alloy system involved.
Chromium and nickel compounds are found in fumes when stainless steels are arc-welded. Some coated and flux-cored electrodes are
formulated with flourides and the fumes associated with them can contain significantly more flourides than oxides. Because of the above
factors, arc-welding fumes frequently must be tested for individual constituents that are likely to be present to determine whether specific
TLV's are exceeded. Conclusions based on inhalable concentration are generally adequate if no toxic elements are present in welding
rod, metal, or metal coating and conditions are not conducive to the formation of toxic gases. Are listed as possibly carcinogenic to
humans by IARC.
Carcinogenicity: See above NTP? No IARC? No OSHA Regulated? No
Zinc No chronic debilitating symptoms indicated. Exposure to dust or fines presents a low health risk by inhalation. Subjecting zinc or alloys
containing zinc to high temperatures (such as occurs during welding) will cause the formation of zinc oxide. Exposure to zinc oxide
fumes subsequent to burning, welding and molten metal can result in "zinc chills," a flu-like illness (metal fume fever). Onset of
symptoms may be delayed 4-12 hours. Early symptoms of metal fume fever include a metallic or sweet taste in the mouth, dryness and
irritation of the throat and coughing. These symptoms may progress to shortness of breath, headache, fever, chills, muscle aches,
nausea, vomiting, weakness, fatigue and profuse sweating. The attack may last 6-48 hours, leaves no effect, and is more likely to occur
after a period away from the job. Gastrointestinal inflammation has been reported in animal studies.
Carcinogenicity: N/A NTP? No IARC? A1* OSHA Regulated? No
Additional Information:
Aluminum dust/fines and fumes are low health risk by inhalation. For standard operations (i.e. machining, cutting, grinding), aluminum should be
treated as a nuisance dust and is so defined by the American Conference of Government Industrial Hygienists (ACGIH).
Welding and plasma cutting of alloys high in copper (2000 and 7000 series) may present an overexposure to copper fumes.
Welding of aluminum alloys may generate carbon monoxide, carbon dioxide, ozone nitrogen oxides, infrared radiation and ultraviolet radiation.
Since lead is a cumulative toxic metal by inhalation or ingestion, appropriate industrial precautions to guard against these two routes of exposure need
to be taken when handling these alloys. Sampling to establish the lead level exposure to airborne particulate or fumes is possible. Consult OSHA Lead
standard 29 CFR 1910.1025 for specific health/industrial hygiene precautions and requirements to follow when handling lead compounds.
NTP (National Toxicology Program) Classifications:
Group 1: Known to be carcinogenic; sufficient evidence from human studies.
Group 2: Reasonably anticipated to be a carcinogen; limited evidence from studies in humans or sufficient evidence from studies in experimental
animals.
IARC ( International Agency for Research on Cancer) Classifications:
Group A1 - Confirmed Human Carcinogen: The agent is carcinogenic to humans based on the weight of evidence from epidiologic studies of, or
convincing clinical evidence in, exposed humans.
Group A2 - Suspected Human Carcinogen: The agent is carcinogenic in experimental animals at dose levels, by route(s) of administration, at site(s), of
histologic type(s), or by mechanism(s) that are considered relevant to worker exposure. Available epidemiologic studies are conflicting or
insufficient to confirm an increased risk of cancer in exposed humans.
Group A3 - Animal Carcinogen: The agent is carcinogenic in experimental animals at dose levels, by route(s) of administration, at site(s), of histologic
type(s), or by mechanism(s) that are not relevant to worker exposure. Available epidemiologic studies do not confirm an increased risk of
cancer in exposed humans. Available evidence suggests that the agent is not likely to cause cancer in humans except under uncommon
or unlikely routes or levels of exposure.
Group A4 - Not Classifiable as a Human Carcinogen: There are inadequate data on which to classify the agent in terms of its Carcinogenicity in humans
and/or animals.
Group A5 - Not Suspected as a Human Carcinogen: The agent is not suspected to be a human carcinogen on the basis of properly conducted
epidemiologic studies in humans.
Signs and Symptoms of Exposure:
Typical symptoms consist of a metallic taste in the mouth, dryness of the throat, chills, fever and influenza-like symptoms, usually lasting from 12 to 48
hours.
Medical Conditions Generally Aggravated by Exposure:
Individuals with chronic respiratory disorders (i.e. asthma, chronic bronchitis, emphysema, etc.) may be adversely affected by fume or airborne
particulate matter exposure.
Emergency and First Aid Procedures:
Inhalation: Remove to fresh air; if condition continues, consult a physician.
Eye Contact: Flush thoroughly with running water for 15 minutes to remove particulate; take care to rinse under eyelids. Obtain medical attention.
Skin Contact: Remove particulate by washing thoroughly with soap and water. Seek medical attention if condition persists. For minor burns, apply
cold water. For severe burns, seek immediate medical attention.
Ingestion: Does not represent a hazard, if significant amounts of metal are ingested, consult physician.

metal, or metal coating and conditions are not conducive to the formation of toxic gases. Are listed as possibly
carcinogenic to humans by IARC.
Carcinogenicity: See above NTP? No IARC? No OSHA Regulated? No
Zinc No chronic debilitating symptoms indicated. Exposure to dust or fines presents a low health risk by inhalation.
Subjecting zinc or alloys containing zinc to high temperatures (such as occurs during welding) will cause the
formation of zinc oxide. Exposure to zinc oxide fumes subsequent to burning, welding and molten metal can result in
"zinc chills," a flu-like illness (metal fume fever). Onset of symptoms may be delayed 4-12 hours. Early symptoms of
metal fume fever include a metallic or sweet taste in the mouth, dryness and irritation of the throat and coughing.
These symptoms may progress to shortness of breath, headache, fever, chills, muscle aches, nausea, vomiting,
weakness, fatigue and profuse sweating. The attack may last 6-48 hours, leaves no effect, and is more likely to
occur after a period away from the job. Gastrointestinal inflammation has been reported in animal studies.
Carcinogenicity: N/A NTP? No IARC? A1* OSHA Regulated? No
*(for zinc chromates)
Additional Information:
Welding and plasma cutting of alloys high in copper (2000 and 7000 series) may present an overexposure to copper fumes..
Since lead is a cumulative toxic metal by inhalation or ingestion, appropriate industrial precautions to guard against these two routes of
exposure need to be taken when handling these alloys. Sampling to establish the lead level exposure to airborne particulate or fumes
is possible. Consult OSHA Lead standard 29 CFR 1910.1025 for specific health/industrial hygiene precautions and requirements to
follow when handling lead compounds.
NTP (National Toxicology Program) Classifications:
Group 1: Known to be carcinogenic; sufficient evidence from human studies.
Group 2: Reasonably anticipated to be a carcinogen; limited evidence from studies in humans or sufficient evidence from studies in
experimental animals.
IARC ( International Agency for Research on Cancer) Classifications:
Group A1 - Confirmed Human Carcinogen: The agent is carcinogenic to humans based on the weight of evidence from epidiologic
studies of, or convincing clinical evidence in, exposed humans.
Group A2 - Suspected Human Carcinogen: The agent is carcinogenic in experimental animals at dose levels, by route(s) of
administration, at site(s), of histologic type(s), or by mechanism(s) that are considered relevant to worker exposure.
Available epidemiologic studies are conflicting or insufficient to confirm an increased risk of cancer in exposed humans.
Group A3 - Animal Carcinogen: The agent is carcinogenic in experimental animals at dose levels, by route(s) of administration, at
site(s), of histologic type(s), or by mechanism(s) that are not relevant to worker exposure. Available epidemiologic studies
do not confirm an increased risk of cancer in exposed humans. Available evidence suggests that the agent is not likely to
cause cancer in humans except under uncommon or unlikely routes or levels of exposure.
Group A4 - Not Classifiable as a Human Carcinogen: There are inadequate data on which to classify the agent in terms of its
Carcinogenicity in humans and/or animals.
Group A5 - Not Suspected as a Human Carcinogen: The agent is not suspected to be a human carcinogen on the basis of properly
conducted epidemiologic studies in humans.
Signs and Symptoms of Exposure:
Typical symptoms consist of a metallic taste in the mouth, dryness of the throat, chills, fever and influenza-like symptoms, usually
lasting from 12 to 48 hours.
Medical Conditions Generally Aggravated by Exposure:
Individuals with chronic respiratory disorders (i.e. asthma, chronic bronchitis, emphysema, etc.) may be adversely affected by fume or
airborne particulate matter exposure.
Emergency and First Aid Procedures:
Inhalation: Remove to fresh air; if condition continues, consult a physician.
Eye Contact: Flush thoroughly with running water for 15 minutes to remove particulate; take care to rinse under eyelids. Obtain
medical attention.
Skin Contact: Remove particulate by washing thoroughly with soap and water. Seek medical attention if condition persists. For minor
burns, apply cold water. For severe burns, seek immediate medical attention.
Ingestion: Does not represent a hazard, if significant amounts of metal are ingested, consult physician.
Section 7 - Precautions for Safe Handling and Use
Steps to be taken in Case Material Is Released or Spilled:
Fine turnings and small chips should be swept or vacuumed. Scrap metal can be reclaimed for re-use.
Waste Disposal Method:
Used or unused product should be tested to determine hazard status and disposal requirements under federal, state or local laws and
regulations.
Precautions to Be Taken in Handling and Storing:
See Section 4.
Other Precautions:
Not requested by USA Department of Transportation.
Section 8 - Control Measures
Respiratory Protection:
Appropriate dust/mist/fume respirator should be used to avoid excessive inhalation of particulates. If exposure limits are reached or
exceeded, use NIOSH/MSHA approved equipment.
Ventilation: Use with adequate ventilation to meet exposure limits listed in Section 2.
Eye Protection: Safety glasses/face shields should be worn when grinding, cutting, or welding.
Protective Gloves: Should be worn as required for welding, burning or handing operations.
Other Protective Clothing/Equipment: As required depending on operations and safety codes.
Work / Hygienic Practices: Wash with soap and water.
