Specific Hazards: Product may burn under intense heat, forms irritating or toxic fumes if combusted (mainly oxides of carbon and sulfur), dust may form explosive mixtures with air
Protective Equipment: Wear full protective clothing and a self-contained breathing apparatus
Fire-Fighting Instructions: Prevent fire-fighting water from entering drains or watercourses, cool unopened containers with water spray, fight fires from upwind position
Personal Precautions: Avoid breathing dust, ventilate area, wear suitable protective clothing, use safety goggles if dust or splashing possible
Environmental Precautions: Prevent entry into waterways, sewers, basements, or confined spaces, contain spill with barriers if safe
Methods for Cleanup: Sweep up carefully to minimize dust, transfer to suitable containers for re-use or disposal, wash area with water after removal, dispose waste in accordance with local regulations
Small Spills: Use vacuum or damp sweeping to avoid dust
Large Spills: Set up dikes or containment, notify authorities if environmental contamination may occur
Handling: Avoid generating dust, use with adequate ventilation, avoid eye and prolonged skin contact, do not eat, drink, or smoke during handling
Storage Conditions: Store in tightly closed original container, keep in cool, dry, well-ventilated place away from incompatible substances such as strong oxidizing agents, store away from heat sources and direct sunlight
Special Hygiene: Wash hands before breaks and at end of shift, keep work area clean, use industrial vacuum for housekeeping
Incompatible Materials: Strong acids, strong bases, oxidizers
Occupational Exposure Limits: No specific exposure limits established by OSHA, ACGIH, NIOSH as of June 2024
Engineering Controls: Use local exhaust ventilation for bulk handling
Protective Equipment: Chemical-resistant gloves (nitrile or PVC), safety goggles or face shield, long-sleeved clothing or lab coat, dust mask in case of dust formation
Hygiene Measures: Wash hands before eating, drinking, or smoking, launder work clothes regularly
