Health Hazards Information - Recommended Personal Protective Equipment: Rubber gloves, safety
goggles, dust mask; Symptoms Following Exposure: Inhalation of fumes can produce coughing, chest
constriction, headache, nausea, vomiting, pneumonitis. Chronic poisoning is characterized by
emphysema and kidney injury. Ingestion causes gasrtrointestinal disturbances and sever toxic
symptoms; both kidney and liver injures may occur. Contact with eyes causes irritation; General
Treatment for Exposure: INHALATION: remove patient to fresh air; seek medical attention.
INGESTION: give large amounts of water and induce vomiting, give milk or egg whites; seek medical
attention. EYES: flush with copious amounts of water for 15 min; consult a physician. SKIN: Wash.

Health Hazards Momtion - Recommended Personal Protective Equipment: ; Symptoms Following
Exposure: A single exposure to cadmium oxide fumes can cause severe or fatal lung irritation; chronic
poisoning is characterized by lung injury (emphysema) and kidney disfunction. Ingestion produces
severe toxic effects, both kidney and liver injures may occur. Contact with eyes causes irritation;
General Treatment for Eqosure: INHALATION; if there has been known exposure to dense cadmium
oxide fume or if cough, chest tightness, or respiratory distress occur after possible exposure, place
patient at bed rest and call a physician. INGESTION induce vomiting, stop irritation by giving milk
or egg whites at frequent intervals; perform gastric lavage; seek medical attention. EYES: flush with
water for at least 15 min; Toxicity by Inhalation (Threshold Limit Value): 0.1 mg/m3; Short-Term
Exposure Limits: 0.1 mg/m3, 30 min; Toxicity by Ingestion: Grade 3; oral rat LD,=72 mg/kg; Late
Toxicity:; Vapor (Gas) Irritant Characteristics: Data not available; Liquid or Solid Irritant
Characteristics: Data not available; Odor Threshold: Data not available.
