Suitable Extinguishing Media: Water spray, dry powder, alcohol-resistant foam, carbon dioxide
Unsuitable Extinguishing Media: Do not use water jet due to risk of spreading material
Specific Hazards: Produces toxic and irritating fumes of hydrogen chloride, nitrogen oxides, and methyl-chloro derivatives under combustion
Protective Equipment: Use self-contained breathing apparatus (SCBA), chemical-resistant suit, full face shield
Advice for Fire-Fighters: Keep containers cool with water spray, contain water runoff and prevent entry into watercourses or drains, evacuate personnel from risk area if possible.
Personal Precautions: Avoid direct contact with spilled material, ventilate area, remove all ignition sources, wear suitable protective equipment (respirator, goggles, gloves, lab coat)
Environmental Precautions: Prevent further leakage or spillage if safe to do so, avoid discharge into drains, watercourses, or soil
Methods for Clean-Up: Collect spilled material in dust-free, chemically resistant liner or container using non-sparking tools, absorb with inert dry material (sand or vermiculite), seal containers for hazardous waste disposal, decontaminate spill site
Reference to Other Sections: Refer to personal protection measures and disposal considerations for further instructions.
Precautions for Safe Handling: Use only in a chemical fume hood with good ventilation, avoid inhalation/exposure, avoid contact with skin, eyes, clothing, practice good industrial hygiene (no eating, drinking, smoking in work area), use tools that reduce dust or splashing risk
Conditions for Safe Storage: Store in a tightly closed chemical-resistant container, in a dry, cool, well-ventilated area away from incompatible materials (oxidizers, acids, strong bases), avoid high humidity, segregate from oxidizing agents or materials likely to interact or decompose
Storage Limitations: Do not store with food or medicines, ensure labels are legible and containers are routinely inspected, store apart from flammable materials.
Incompatible Materials: Strong acids, strong oxidizing agents, some metals (due to chlorides potential to corrode), avoid contact with peroxides.
Control Parameters: No established occupational exposure limits, monitor for airborne dust or vapors using workplace air sampling or local hazard policies.
Engineering Controls: Use local exhaust ventilation, fume hood recommended, laboratory airflow monitoring essential for higher volumes.
Personal Protective Equipment: Wear chemical-resistant gloves (nitrile or neoprene), lab coat, chemical splash goggles, face shield for face protection, use certified respiratory protection for dust-generating or high-concentration tasks
Hygiene Measures: Shower and wash thoroughly after handling, launder contaminated clothing, keep PPE separate from general clothing, do not eat or drink in laboratory
Environmental Exposure Controls: Level controls to prevent uncontrolled emissions or releases, collect and treat liquid effluents and solid residues using site-specific hazardous waste procedures.
