Zinc Sulfate Monohydrate

SECTION 2: Hazards identification

EMERGENCY OVERVIEW APPEARANCE: White, free-flowing granules PHYSICAL FORM: Dry ODOR: Essentially Odorless

Signal word

None EMERGENCY OVERVIEW: Colorless, odorless granules. Not flammable or explosive, but will decompose in extreme heat to produce toxic sulfur oxide gas and zinc oxide fume. The granular solid or dust is relatively non-toxic to humans and poses little immediate hazard to emergency response personnel but is freely soluble in water and con pose a threat to watercourses. SYMPTOMS OF OVEREXPOSURE BY ROUTE OF EXPOSURE: The primary routes of overexposure for this material are via inhalation and contact with skin and eyes. The following paragraphs describe the symptoms of overexposure to this material. INHALATION: If dust, mists, or sprays of this product are inhaled, they may irritate the nose, throat, and lungs. Symptoms may include the following: sneezing, coughing, and difficulty breathing. Severe overexposures can result in damage to respiratory system tissues. Most symptoms generally are alleviated when the overexposure ends. CONTACT WITH SKIN or EYES: Depending on the duration of skin contact, skin overexposures can cause reddening, discomfort, and moderate irritation, but would not normally cause tissue damage. Eye contact may cause irritation, possibly severe. SKIN ABSORPTION: Skin absorption is not a significant route of overexposure for Zinc Sulfate Monohydrate. INGESTION: In general, zinc sulfate is very astringent, and when ingested in large quantities, symptoms of over-exposure can include nausea, abdominal pain, vomiting, and diarrhea. Severe ingestion overexposures can result in convulsions and collapse. ACUTE: The primary hazard associated with this product is the potential for moderate irritation of skin, eyes, and other contaminated tissue. Ingestion of this product can be harmful or fatal. CHRONIC: In general, zinc is considered to be a low toxicity metal. Zinc is very important trace element for humans and the body regulates the amount of zinc stored by decreasing absorption and increasing excretion when intake is increased. Industrial experience has not identified any significant chronic effects from zinc sulfate to date. Zinc sulfate is not listed as a carcinogen by the Occupational Safety and Health Administration (OSHA), the National Toxicology Program (NTP), the International Agency for Research on Cancer (IARC), the American Conference of Governmental Industrial Hygienists (ACGIH), or the European Union (EU).
