Chemical Name: Zinc Methionine
Other Names: Zinc bis-L-methionine, Methionine zinc salt
CAS Number: 56329-42-1
Appearance: White to light yellow powder
Odor: Weak or characteristic amino acid scent
Uses: Nutritional supplement, animal feed additive
Health Hazards: Mild eye irritation, possible skin discomfort, harm if swallowed in larger doses, dust may irritate airways and lungs
Environmental Hazards: Potential risk to aquatic life in large spills
Label Elements: Irritant symbol, warning for dust inhalation
Main Ingredient: Zinc Methionine
Percentage: Often above 95% in technical grades
Other Components: Unreacted methionine or zinc salts, residual moisture
Inhalation: Move away from the source, go outside, and get fresh air
Eye Contact: Rinse under gentle running water for several minutes, keep eyelids open
Skin Contact: Wash thoroughly with soap and plenty of water
Ingestion: Rinse mouth, drink water if conscious, seek help if feeling sick
Advice for Physicians: Treat symptoms; watch for allergic or severe reactions
Suitable Media: Water spray, dry chemical powder, foam, or carbon dioxide
Unusual Risks: No special fire hazards from the material; containers may burst under high heat
Protective Equipment: Full protective gear, self-contained breathing apparatus
Combustion By-products: Zinc oxides, sulfur oxides, nitrogen oxides
Personal Precautions: Wear gloves and dust masks, keep dust from eyes, avoid inhaling powder
Environmental Precautions: Keep from drains, contain pellet or powder spills
Cleanup Methods: Pick up without making dust, collect in suitable container, dispose as per local guidelines, sweep area well after collection
Handling: Avoid breathing dust, handle in well-ventilated spots, prevent dust build-up on surfaces,
Storage: Keep containers shut tight, store cool and dry, keep out of sunlight, keep away from acids or oxidizers, always label containers
Engineering Controls: Local exhaust fans, dust collection, eyewash stations within reach
Personal Protection: Gloves that resist chemicals, fitted goggles, dust mask or simple respirator, wash up before eating or drinking
Hygiene: Avoid eating, smoking, or touching face in the work area, keep skin clean
Form: Fine granules or crystalline powder
Color: White, off-white, or slightly yellow
Melting Point: Decomposes at elevated heat
Solubility: Partially soluble in water
Odor: Light sulfur note typical of amino acids
Bulk Density: Moderate, varies by form
Stability: Holds up in normal use, humidity damages quality over time
Reactive With: Strong acids, strong bases, oxidizers
Hazardous By-products: Strong heat may give off sulfur or zinc fumes
Acute Effects: Swallowing high doses causes stomach upset, large exposures could trigger headache or nausea
Chronic Effects: Overexposure over days may affect liver or kidneys, inhaling dust often could inflame lungs
Sensitization: Not known to trigger allergies for most people
Carcinogenicity: Not listed by IARC, OSHA, or NTP as a cancer risk
Aquatic Toxicity: Zinc can harm fish if it reaches waterways
Persistence: Zinc does not break down easily; accumulates in sediment
Bioaccumulation: Higher risk in low-flow or poor-drainage areas
Mobility: Dust can spread in windy or dry places; contains to prevent run-off
Waste Disposal: Gather unused powder, place in approved containers, avoid dumping in drains or trash
Special Instructions: Bring to local hazardous waste collection sites, follow local guidelines, burn only if rules allow and only in controlled conditions
Hazard Class: Not regulated on roads or rails if dry and in tight packages
Packaging Advice: Sealed bags or barrels, label to warn handlers of dust risk
Shipping Notes: Keep upright, avoid dampness or breakage that could create dust
OSHA: No Permissible Exposure Limit for this compound, but zinc and methionine standards may apply
EPA: Controls on zinc in water may affect discharge or disposal rules
Workplace Rules: Clean-up plans for dust spills, rules for employee training about chemical safety, labels for secondary containers
