Ingestion: Rinse mouth with water, do not induce vomiting unless directed by medical personnel, seek immediate medical advice
Most Important Symptoms: Burning sensation, irritation, redness, coughing, possible stomach discomfort
Suitable Extinguishing Media: Use water spray, carbon dioxide, dry chemical powder, or foam
Unsuitable Extinguishing Media: Do not use a high pressure water stream, as it may spread the fire
Specific Hazards: Combustion produces toxic fumes such as carbon monoxide, carbon dioxide, hydrochloric acid, and other chlorinated compounds
Firefighter Protection: Wear self-contained breathing apparatus, full protective gear to prevent contact with skin and eyes
Additional Notes: Cool containers with water spray to prevent rupture from heat exposure, prevent contaminated firewater runoff
Personal Precautions: Ventilate area, keep unprotected persons away, wear appropriate protective equipment to avoid contact with eyes, skin, and inhalation
Environmental Precautions: Prevent spillage from entering sewers, drains, waterways, or soil, contain spill with sand or earth
Cleanup Methods: Collect spilled material with inert absorbent, transfer to tightly sealed waste containers for proper disposal, clean affected area thoroughly with water and detergent
Decontamination: Wash contaminated surfaces and ventilate area before re-entry
Emergency Procedures: Evacuate personnel not involved with cleanup, notify safety officer or environmental authority if large spill occurs
Handling: Use only in well ventilated areas, avoid contact with skin, eyes, and clothing, wash hands after handling, never eat, drink, or smoke during use, minimize the generation of vapors and fumes
Storage: Store in tightly closed original container, keep in a cool, dry, well-ventilated location away from incompatible substances like strong acids, bases, and oxidizers, protect from direct sunlight and moisture
Incompatible Materials: Avoid contact with strong oxidizing agents, strong acids and alkalis, chlorinated solvents
Special Requirements: Store away from food, beverages, animal feed, and other sensitive materials
Occupational Exposure Limits: Occupational limits not established for Methyl 5-Chlorovalerate, but keep exposure as low as possible
Engineering Controls: Use processes enclosures, local exhaust ventilation, or other engineering controls to keep airborne concentrations below recommended exposure limits
Personal Protective Equipment: Eyes/Face: Chemical safety goggles, face shield as necessary. Skin: Chemical-resistant gloves (e.g. nitrile), protective clothing with long sleeves. Respiratory: Use a properly fitted respirator if ventilation is inadequate or risk of exposure to vapors exists.
Hygiene Measures: Wash hands and exposed skin before eating, drinking, or smoking. Remove and wash contaminated clothing before reuse.
