Firefighting Instructions: Use self-contained breathing apparatus and full protective gear to prevent contact with skin and eyes, avoid inhalation of vapors or combustion products, keep containers cool with water spray
Special Risks: Product decomposition releases toxic and irritating gases under fire conditions, runoff from fire control may pollute water sources
Personal Precautions: Wear personal protective equipment, avoid breathing vapors and contact with skin or eyes, ensure adequate ventilation
Environmental Precautions: Prevent spillage from entering drains, surface water, or soil, notify relevant authorities in case of environmental release
Cleanup Procedures: Contain and collect spillage with non-combustible absorbent material such as sand, earth, or vermiculite, place in suitable closed containers for disposal, wash contaminated area with water, ventilate area, dispose waste in accordance with local regulations
Handling: Avoid breathing dust, vapors, and mist, handle with care, wash hands thoroughly after handling, use only in well-ventilated areas, minimize dust generation and accumulation, prevent exposure by using appropriate engineering controls and PPE
Storage: Keep containers tightly closed in a cool, dry, well-ventilated space, store away from incompatible substances such as strong oxidizers, acids, store at room temperature but away from direct light, moisture, ignition sources, or heat, ensure containers are labeled properly and sealed to avoid contamination
Engineering Controls: Use process enclosures, local exhaust ventilation, or other engineering controls to maintain airborne levels below recommended exposure limits
Personal Protective Equipment: Safety goggles or face shield, impervious gloves (nitrile or neoprene), lab coat or chemical-resistant clothing, suitable protective footwear
Respiratory Protection: Use approved respirators if ventilation is inadequate or exposure limits are exceeded
Hygiene Practices: Remove contaminated clothing and wash before reuse, wash hands before breaks and after handling, do not eat, drink, or smoke in the work area
