Eye Contact: Rinse cautiously with water for several minutes. Remove contact lenses. Continue rinsing. If irritation persists, seek medical help.
Ingestion: Rinse mouth. Do not induce vomiting unless directed by medical personnel. Seek immediate medical assistance.

5. Fire-Fighting Measures

Suitable Extinguishing Media: Dry chemical, carbon dioxide, foam, water spray (do not use water jet).
Specific Hazards: Emits toxic fumes of hydrogen chloride and carbon oxides under fire conditions. Vapors can form explosive mixtures with air.
Protective Equipment for Firefighters: Wear self-contained breathing apparatus (SCBA) and full protective gear. Avoid inhaling gases, vapors, or smoke.
Firefighting Instructions: Move containers from fire area if it can be done safely. Use water spray to cool fire-exposed surfaces and to disperse vapors.

6. Accidental Release Measures

Personal Precautions: Use personal protective equipment. Avoid breathing vapors. Ventilate area. Evacuate unnecessary personnel.
Environmental Precautions: Prevent further leakage or spillage if it is safe. Do not let product enter drains, surface water, or soil.
Cleanup Methods: Contain spill with inert material (sand, earth). Collect in suitable containers. Dispose of according to local and national regulations. Wash spill area thoroughly after cleanup.

7. Handling and Storage

Handling: Avoid contact with skin and eyes. Do not inhale vapors or mist. Use only with adequate ventilation. Keep away from sources of ignition. Ground and bond containers when transferring material. Practice good industrial hygiene and safety procedures.
Storage: Store in tightly closed containers in a cool, dry, ventilated place. Keep away from incompatible substances such as strong oxidizers, acids, and alkalis. Protect from sunlight, heat, and moisture.

8. Exposure Controls and Personal Protection

Exposure Limits: No OSHA PEL or ACGIH TLV established. Minimize exposure as a general precaution.
Engineering Controls: Use local exhaust ventilation, process enclosures or other engineering controls to keep airborne levels below recommended exposure limits.
Personal Protective Equipment: Chemical-resistant gloves (nitrile or neoprene), safety goggles or face shield, protective clothing. Where vapor concentrations exceed limits, use NIOSH approved respirator.
Hygiene Measures: Wash hands before breaks and after work. Remove contaminated clothing. Do not eat, drink, or smoke when handling chemicals.
