First Aid Measures

Inhalation: Move person to fresh air. Seek medical help if symptoms persist, such as coughing or trouble breathing.
Skin Contact: Remove contaminated clothing. Wash with soap and water for at least 15 minutes. If irritation remains, see a doctor.
Eye Contact: Rinse eyes slowly and gently with water for 15 minutes, holding eyelids open. Get medical advice right away.
Ingestion: Do not induce vomiting. Rinse mouth with water. Seek prompt medical attention.
Most Important Symptoms: Burning sensation, coughing, skin redness, eye watering, headache, dizziness

Fire-Fighting Measures

Suitable Extinguishing Media: Use dry chemical, carbon dioxide, alcohol-resistant foam. Avoid water jets.
Special Hazards: Generates toxic gases like hydrogen chloride and carbon oxides on combustion.
Protective Equipment for Firefighters: Wear self-contained breathing apparatus and protective clothing.
Specific Hazards: Vapors may form explosive mixtures with air. Containers exposed to fire may burst.

Accidental Release Measures

Personal Precautions: Evacuate area. Avoid vapor inhalation. Ventilate zone. Wear gloves, goggles, and respirator as needed.
Methods for Containment and Clean-Up: Stop leak if safe. Absorb with inert material like sand or earth, collect for disposal. Wash spill area with plenty of water.
Environmental Precautions: Prevent run-off into waterways, soil, or drains. Notify authorities if water contamination risk exists.
Chemical Precautions: Keep away from heat; avoid mixing with acids, bases, or oxidizers.

Handling and Storage

Safe Handling: Wear goggles, gloves, lab coat, and a fume hood on hand. Only handle in well-ventilated areas. Do not eat, drink, or smoke during use.
Storage Conditions: Store tightly closed in a cool, dry, ventilated area. Keep away from sources of ignition, acids, and oxidizing agents.
Specific Requirements: Use explosion-proof equipment. Ground containers to prevent static discharge.
Incompatibles: Strong oxidizers, alkalis, and acids react with 1-chlorooctane.

Exposure Controls and Personal Protection

Engineering Controls: Chemical fume hood, local exhaust. Safety shower and eyewash station within reach.
Occupational Exposure Limits: No established OSHA/NIOSH limits for 1-chlorooctane; treat with care; follow general guidelines for organic solvents.
Personal Protective Equipment: Gloves (nitrile or neoprene recommended), safety goggles, flame-retardant lab coat, proper shoes. Respiratory protection if vapor exposure risk is present.
Hygiene Measures: Wash hands thoroughly after handling. Remove contaminated clothing before eating or drinking.
