Environmental Precautions: Prevent entry into drains, waterways, or soil
Methods for Clean-Up: Collect and shovel spilled material into dry, labeled containers, ventilate area, wipe residues with damp cloth, dispose as hazardous chemical waste
Decontamination: Clean area with plenty of water, avoid water run-off into environment
Safe Handling: Use in well-ventilated area, avoid dust generation, keep container tightly closed, do not eat, drink, or smoke while using chemical
Storage Conditions: Store in tightly sealed original container in a cool, dry, well-ventilated place away from incompatible substances (strong oxidizers, alkalis), protect from moisture and direct sunlight
Incompatible Materials: Strong acids, bases, oxidizing agents
Storage Class: Chemical storage, isolated from food and feedstuff
Engineering Controls: Use fume hood or local exhaust ventilation, keep work area clean and free from dust
Personal Protective Equipment: Chemical-resistant gloves (nitrile or neoprene), safety goggles, laboratory coat, protective footwear
Respiratory Protection: Use dust mask or respirator if handling powder in bulk or where ventilation is inadequate

Other Information: Prolonged or repeated exposure could cause skin dryness or cracking
Ecotoxicity: Harmful to aquatic life, toxic to fish and invertebrates at moderate concentrations (specific data limited)
Persistence and Degradability: Not readily biodegradable, may persist in environment
Bioaccumulative Potential: No significant potential for bioaccumulation expected
Mobility in Soil: Likely to leach with water through soil due to high solubility
Other Adverse Effects: Do not allow chemical or waste to enter waterways, may cause damage to local water systems
Waste Disposal Methods: Dispose of in accordance with local and national regulations for hazardous chemical waste, collect in sealed containers for chemical incineration
Contaminated Packaging: Rinse thoroughly, render unsuitable for further use, dispose as chemical waste
Other Guidelines: Consult licensed waste disposal service, do not dump untreated residues into drains or surface water
