11. TOXICOLOGICAL INFORMATION
Information on the Toxicological Effects of Substances / Mixture
Acute Toxicity Hazard LC50/LD50 Data
Inhalation Non-hazardous LC50 >5 mg/l (dust)
Skin Absorption Non-hazardous LD50 >2000 mg/kg
Ingestion Non-hazardous LD50 >5000 mg/kg
Note: Steel products, under normal conditions, do not present an inhalation, ingestion or skin hazard. However,
operations such as welding, grinding, sawing and burning, which may cause airborne particulates or fume
formation, may present a health hazard.
Skin Corrosion / Irritation: Contact with dusts or particulates produced by cutting, welding or grinding may be
abrasive and mildly irritation to the skin. Particulates ay cause a red-brown pigmentation of the skin following
repeated exposure.
Serious Eye Damage / Irritation: Contact with dusts or particulates produced by cutting, welding or grinding
may be abrasive and irritation to the eyes and cause stinging, watering and redness.
Signs and Symptoms: Effects of overexposure my include irritation of the nose and throat and digestive tract.
Skin Sensitization: Nickel, a component, may cause an allergic skin reaction.
Respiratory Sensitization: Not expected to be a respiratory sensitizer.
Germ Cell Mutagenicity: This material and its components have not been identified as mutagenic.
Cancer: No information available on the cancer hazard of this material. However, nickel, a component, has
been identified as a cancer hazard (see below).
Reproductive Toxicity: No information available on the reproductive hazard of this material. However,
manganese, a component, has demonstrated some effects on the male reproductive system. These effects are
not sufficient enough to classify the material as a reproductive hazard (see below).
Specific Target Organ Toxicity (Single Exposure): Not expected to cause organ effects from single exposure.
Specific Target Organ Toxicity (Repeated Exposure): Not expected to cause organ effects from repeated
exposure. Although Nickel has effects on the respiratory system, it is in this material below 1%.
Aspiration Hazard: Not applicable.
Manganese CAS# 7439-96-5
Repeated administration of manganese resulted in limited evidence of male reproductive effects in laboratory
animals. The adverse effects included decreased spermatids, spermatocytes and degeneration of
seminiferous tubules. Chronic administration of certain inorganic manganese salts has resulted in limited
evidence of central nervous system effects in laboratory animals. The effects included degenerative changes
in basal ganglionic cells. These effects do not meet the criteria for classifying it as a reproductive toxicant.
Nickel CAS# 7440-02-0
There is limited evidence in animals for the carcinogenicity of metallic nickel, nickel monoxides, nickel
hydroxides and crystalline nickel sulfides, and limited evidence in animals for other nickel compounds (e.g.,
alloys, arsenides and nickel carbonyl). Occupational exposure has been associated with cancer of the lung
and nasal cavity. Nickel and nickel compounds have been identified as carcinogens by NTP and IARC.
