ROUTE(S) OF ENTRY: Inhalation? Yes , Skin? No , Eyes? No , Ingestion? Yes , Other: N
HEALTH HAZARDS (ACUTE AND CHRONIC)
Zinc has variable toxicity, but generally of low toxicity. Zinc is not inherently a toxic element. However, when
heated, it evolves a fume of zinc oxide which, when inhaled fresh, can cause a disease know as "brass
founders,""ague," or "brass chills." There is no cumualtive effect from the inhalation of zinc fumes. (Sax,
Dangerous Properties of Industrial Materials, eighth edition)
Inorganic arsenic compounds are confirmed human carcinogens producing tumors of the mouth, esophagus,
larynx, bladder, and para nasal sinus. A recognized carcinogen of the skin, lungs and liver. Poisoning from arsenic
compounds may be acute or chronic. Acute poisoning ususally results from swallowing arsenic compounds;
chronic poisoning from either swallowing or inhaling. (Sax, Dangerous Properties of Industrial Materials, eighth
edition)
INHALATION:
Acute: DANGER-POISON. May cause irritation to the respiratory system.
Chronic: DANGER-POISON. May cause chronic arsenic poisoning, ulceration of the nasal septum, liver
damage and cancer/disease of the blood, kidneys and nervous system.
INGESTION:
Acute: DANGER-POISON. May cause systemic gastrointestinal and skin effects and acute arsenic poisoning.
Chronic: DANGER-POISON. May cause chronic arsenic poisoning, gastrointestinal disturbances, liver damage
and cancer/disease of the blood, kidneys and nervous system.
SKIN:
Acute: May cause irritation and skin abnormalities.
Chronic: May cause irritation, occasional ulceration, spotty pigmentation, dermatitis, skin cancer and keratoses
(especially on soles and palms).
EYE:
Acute: May cause irritation.
Chronic: No chronic health effects recorded.
TARGET ORGANS: May affect the liver, kidneys, skin, lungs and lymphatic system.
CARCINOGENITICY: NTP? Yes , IARC Monographs? Yes , OSHA Regulated? Yes
CARCINOGENICITY/OTHER INFORMATION
No data available.
RECOMMENDED EXPOSURE LIMITS: See "Section II" LD 50/LC 50: No toxicity data recorded
SIGNS AND SYMPTOMS OF EXPOSURE
INHALATION: May cause laryngitis, bronchitis, and huskiness of the voice. Chronic arsenic poisoning may

cause: disturbances of the digestive system such as loss of appetite, cramps, nausea, constipation or diarrhea.
INGESTION: May cause gastrointestinal disturbances, irritation of the nose and conjunctiva, skin eruptions and
inflammation. Acute arsenic poisoning may cause: irritation of the stomach and intestines with nausea, vomitis and
stools are bloody, collapse and shock with weak rapid pulse and cold sweats. May cause chronic arsenic
poisoning, see inhalation symptoms.
SKIN: May cause redness, itching, ulcerations, and pigmentation changes.
EYE: May cause redness, itching and burning.
MEDICAL CONDITIONS GENERALLY AGGRAVATED BY EXPOSURE
Pre-existing respiratory and skin disorders
EMERGENCY AND FIRST AID PROCEDURES
INHALATION: Remove victim to fresh air; keep warm and quite; give oxygen if breathing is difficult and seek
medical attention immediately.
INGESTION: If conscious, give 1-2 glasses of milk or water and induce vomiting; seek medical attention
immediately.
SKIN: Remove contaminated clothing from affected area; brush material off skin; wash affected area with mild
soap and water; seek medical attention immediately.
EYE: Flush eyes with lukewarm water, lifting upper and lower eyelids, for at least 15 minutes. Seek medical
attention immediately.
