Impurities: May contain trace amounts of other terpenes
Chemical Family: Terpenoid compounds and hydrocarbons

First Aid Measures

Inhalation: Move to fresh air, monitor breathing, seek medical help if symptoms persist
Skin Contact: Immediately remove contaminated clothing, wash skin thoroughly with soap and water, seek medical attention for irritation or allergic response
Eye Contact: Rinse gently with water for at least 15 minutes, remove contact lenses if present, seek medical attention if discomfort continues
Ingestion: Do not induce vomiting, rinse mouth, call poison control or seek immediate medical advice, do not give anything by mouth to an unconscious person

Fire-Fighting Measures

Suitable Extinguishing Media: Carbon dioxide, dry chemical powder, foam, avoid direct streams of water
Unsuitable Extinguishing Media: Water jets can spread burning liquid
Hazardous Combustion Products: Carbon monoxide, carbon dioxide, irritating smoke
Protective Equipment for Firefighters: Full protective suit and self-contained breathing apparatus required
Special Precautions: Cool containers exposed to flames with water spray to prevent rupture, watch for runoff contamination

Accidental Release Measures

Personal Precautions: Eliminate ignition sources, ventilate area, use personal protective equipment like gloves and goggles
Environmental Precautions: Prevent product from entering drains, soil, or waterways
Cleanup Methods: Absorb with inert material such as sand or earth, collect and seal in labeled containers for disposal, decontaminate spill area with soapy water
Other: Avoid direct contact, notify responsible authorities if large spill occurs

Handling and Storage

Handling: Avoid inhalation of vapor, contact with skin and eyes, use in well-ventilated spaces, ground and bond containers when transferring, use non-sparking tools
Storage: Store in tightly closed original container, in cool and well-ventilated area, away from direct sunlight, heat, sources of ignition and incompatible substances such as oxidizers
Specific Concerns: Keep away from children and animals, avoid static discharge hazards

Exposure Controls and Personal Protection

Occupational Exposure Limits: No OSHA or ACGIH occupational limits for lemon oil components, but limit vapor exposure where possible
Engineering Controls: Ensure adequate ventilation, use local exhaust as needed
