Fire-Fighting Measures

Suitable Extinguishing Media: Dry chemical, CO₂, water spray, or alcohol-resistant foam depending on size and location of fire.
Specific Hazards: Product decomposes to toxic fumes of hydrogen chloride, nitrogen oxides, and carbon monoxide when exposed to heat or flame.
Protective Equipment: Firefighters need full protective clothing, self-contained breathing apparatus, and chemical-resistant boots and gloves.
Advice for Firefighters: Approach fire from upwind location. Avoid inhaling combustion products. Use water spray to cool containers near fire.

Accidental Release Measures

Personal Precautions: Wear chemical splash goggles, acid-resistant gloves, lab coat, and a respirator if ventilation is poor. Evacuate unnecessary personnel from the area.
Environmental Precautions: Prevent chemical from entering waterways, drains, or soil to avoid contamination.
Cleanup Methods: Ventilate affected area. Sweep up spilled powder carefully. Avoid producing dust. Place in suitable, labeled containers for disposal. Wash spill area thoroughly with water. Report releases as required by local regulations.

Handling and Storage

Handling: Handle only in well-ventilated locations or fume hoods. Keep away from incompatible substances, such as strong oxidizers, acid chlorides, and alkali metals. Avoid inhalation, skin, or eye contact. Do not eat, drink, or smoke while handling.
Storage: Store tightly sealed in a dry, cool, well-ventilated area away from sunlight. Keep containers upright and clearly labeled. Keep away from sources of ignition and moisture. Store separately from incompatible materials.

Exposure Controls and Personal Protection

Control Parameters: No established occupational exposure limits as of latest guidance. Use local exhaust ventilation or mechanical systems as primary engineering controls.
Personal Protective Equipment: Chemical splash goggles, laboratory coat, acid-resistant gloves, and appropriate dust mask or respirator for airborne concentrations.
Engineering Controls: Handle in a chemical fume hood or an environment equipped with eyewash stations and safety showers.
General Hygiene: Wash hands and exposed skin before eating or leaving work area. Remove and wash contaminated clothing.

Other Data: Extensive exposure may cause lasting damage to skin or eyes.

Ecological Information

Ecotoxicity: May be hazardous to aquatic organisms, especially at high concentrations.
Persistence: Breaks down in aqueous environments, but chloride ions may persist.
Bioaccumulation Potential: Low due to high solubility and limited bioaccumulative properties.
Mobility in Soil: High solubility leads to mobility and possible groundwater contamination.
Other Adverse Effects: Spilling large quantities may disrupt aquatic habitats.

Disposal Considerations

Waste Treatment Methods: Collect residues in tightly sealed, properly labeled containers. Use an approved chemical waste disposal contractor, following local, regional, and national regulations.
Disposal of Contaminated Packaging: Empty packaging must be treated with the same precautions as unused material, or disposed of as hazardous waste.
Additional Information: Do not dump into sewers or the environment. Incineration or chemical treatment may be permitted if in accordance with environmental guidelines.
