Protective Equipment: Full protective clothing, self-contained breathing apparatus.
Advice: Remove containers from fire zone if safe, control runoff to prevent environmental contamination.
Special Procedures: Keep exposed containers cool with water spray, monitor for secondary explosions due to gas buildup.
Personal Precautions: Use suitable gloves, lab coat, eye and face protection, avoid breathing vapor.
Environmental Precautions: Prevent spillage from entering waterways, soil, or drains, alert environmental authorities in large releases.
Small Spill Methods: Absorb with inert material (vermiculite, sand), transfer to waste container for disposal; ventilate area.
Large Spill Methods: Dike far ahead of spill for later recovery, clean up promptly with trained personnel, dispose in accordance with regulatory requirements.
Decontamination: Wash area with plenty of water after removal, remove contaminated clothing and clean or discard.
Disposal of Waste: Consult section on disposal considerations.
Handling: Avoid contact with eyes, skin, or clothing, do not breathe vapors or dusts. Use only in well-ventilated areas, wear appropriate PPE. Never handle near sources of ignition, heated surfaces, or open flames. Keep work area organized to prevent accidental spillage and confusion during emergency.
Storage: Store in tightly sealed original container, out of direct sunlight, away from incompatible substances including acids, bases, and strong oxidizers. Keep at ambient temperatures, protect from moisture. Preferably store in ventilated chemical cabinet labeled with hazard class. Monitor regularly for leaks or degrading containers.
Engineering Controls: Use chemical fume hood, eyewash stations, and emergency showers should be nearby. Ensure adequate general ventilation. Where handling amounts above laboratory scale, install local exhaust or containment.
Personal Protective Equipment (PPE): Wear chemical-resistant gloves (nitrile or equivalent), lab coat, protective goggles, and if risk of splashing or aerosolization, a full face shield. Wear suitable respirator if exposure exceeds occupational limit or in poor ventilation.
Hygiene Measures: Wash hands, forearms, and face after handling. Remove contaminated work clothing before leaving work area, launder before reuse. Do not eat, drink, or smoke during use.
Exposure Limits: No occupational exposure limit values listed, minimize exposure as much as practicable.
