Special Precautions: Use non-sparking tools. Ventilate area. Waste should not re-enter the environment.
Handling: Avoid vapor and mist formation. Use only in well-ventilated areas. Wear suitable personal protective equipment. Keep containers tightly closed. Handle well away from ignition sources.
Storage: Store in cool, dry, well-ventilated facility in original, corrosion-resistant containers. Segregate from strong bases, acids, oxidizers. Keep away from direct sunlight, sources of heat. Store locked up.
Occupational Exposure Limits: ACGIH TLV not established; handle as hazardous
Engineering Controls: Use fume hoods, exhaust ventilation, and process enclosures where feasible
Personal Protective Equipment: Chemical-resistant gloves (nitrile, butyl rubber), safety goggles, impervious lab coat, chemical splash apron, appropriate respirators if airborne levels exceed exposure limits
Hygiene Measures: Wash hands, forearms, and face thoroughly after handling and before breaks. Do not eat, drink, or smoke in areas where this substance is processed or stored.
