Special Procedures: Keep run-off out of drains and water courses, cool containers with water spray to prevent rupture
Personal Precautions: Wear mask, gloves, goggles to prevent exposure
Environmental Precautions: Prevent entry into waterways, drains, or soil
Methods for Clean Up: Scoop or shovel material into sealable, labeled containers for reuse or disposal, minimize dust generation, ventilate area
Spill Response: Wash area with water after dry material collection, prevent residue from entering environment
Safe Handling: Use in well-ventilated areas to avoid dust buildup, wear proper PPE to minimize contact, keep containers tightly closed
Storage Requirements: Store in cool, dry, well-ventilated site, away from moisture and incompatible chemicals (strong acids, oxidizers), use lined and labeled containers
Incompatibilities: Reacts with strong acids to release ammonia gas, keep away from alkalis
Storage Temperature: No special temperature controls, avoid excessive heat
Handling Advice: Limit spillage, keep handling equipment decontaminated and dry
