Methods for Clean-Up: Collect spillage using non-sparking tools; clean contaminated floor with water and detergent
Handling: Avoid dust formation; handle in well-ventilated areas; use local exhaust to minimize exposure
Protection: Wear chemical-resistant gloves and eye/face protection; use protective clothing if handling large volumes
Hygiene: Wash hands and exposed skin after handling; no food or drinks nearby; remove contaminated clothing before area exit
Storage: Store in original, tightly closed packaging in a dry, cool, ventilated place away from incompatible substances like strong bases, reducing agents, oxidizers
Storage Life: Granules remain stable and effective in suitable packaging for at least 24 months
Storage Temperature: Below 35°C, out of direct sunlight; avoid freezing
Exposure Limits: No specific occupational exposure limit established; minimize dust exposure
Engineering Controls: Local exhaust ventilation recommended to maintain airborne concentrations below nuisance levels
Personal Protection: Approved dust respirator for handling dry product; chemical splash goggles and face shield for risk of splashes; chemical-resistant gloves; lab apron or long-sleeved clothing
Environmental Controls: Measures to prevent pollution, avoid spillage into waterways or soil
