Section 11 - Toxicological Information
There are no Lethal Concentration/Dose information for galvanized steel products. Steel products under normal
conditions do not present an inhalation, ingestion, or contact health hazard. However, operations such as burning,
welding, sawing, brazing, grinding, and possibly machining, etc., which result in elevating the temperature of the product
to or above its melting point or result in the generation of airborne particulates, may present health hazards.
Information provided below addresses potential exposure to dust or fume resulting from the operations identified above.
Inhalation of zinc oxide (welding fume) may result in metal fume fever, which includes chills, muscle ache, nausea, fever,
dry throat, cough; lassitude (weakness, exhaustion); metallic taste; headache; blurred vision; low back pain; vomiting;
malaise (vague feeling of discomfort); chest tightness; dyspnea (breathing difficulty), decreased pulmonary function.
Chronic inhalation of high concentrations of iron oxide fumes or dusts may lead to a benign pneumoconiosis (siderosis).
Inhalation of high concentrations of ferric oxide may possibly enhance the risk of lung cancer development in workers
exposed to pulmonary carcinogens. No long term effects of metal fume fever have been noted. IDLH=500 mg/M3. The
International Agency for Research on Cancer (IARC) of the World Health Organization recently reclassified Welding fumes
from IARC Group 2B, “possibly carcinogenic to humans” to IARC Group 1, “carcinogenic to humans”.
See Section 2 for Hazard Symbols, Hazard Classifications, Signal Words, Hazard Statements, and Precautionary
Statements.
