Health hazards
0 - MINIMAL FLAMMABILITY HAZARD 0 - MINIMAL REACTIVITY HAZARD 0 - MINIMAL PERSONAL PROTECTION B - Glasses, Gloves EMERGENCY OVERVIEW: A tan to off-white aqueous slurry. Low toxicity. Not a fire or spill hazard. Avoid storage of product in tanks/drums constructed of aluminum. Dust is classified as a “nuisance particulate not otherwise regulated”. Target Organs: No hazard in normal industrial use. Primary route(s) of entry: Inhalation Acute effects: Overexposure to mist/particulate may cause physical eye and upper respiratory irritation. Page 1 --- HAZARD IDENTIFICATION continues on page 2 --- Page 1
Potential chronic health
Not hazardous in normal industrial use. Dust from dried product slurry is classified as a “nuisance particulate, not otherwise regulated” as specified by ACGIH and OSHA. Signs & symptoms of overexposure: Eye contact: Low toxicity. Particulate is a physical eye irritant. Skin contact: Low toxicity by skin contact. Inhalation: Low toxicity by inhalation route. Ingestion: An unlikely route of exposure. If ingested in sufficient quantity, may cause gastrointestinal disturbances. Symptoms may include irritation, nausea, vomiting and diarrhea.
