Guidance on Safe Use
Administrative data
First-aid measures
General: Move into fresh air and keep at rest. Get medical attention immediately.
Description of first aid measures
Inhalation: Move the exposed person to fresh air at once. If respiratory problems, artificial respiration/oxygen. Call a physician or poison control center immediately.
Eye contact: Immediately flush with plenty of water for at least 15 minutes. If easy to do, remove contact lenses. Obtain medical attention without delay, preferably from an ophthalmologist.
Skin Contact: Wash skin thoroughly with soap and water for at least 15 minutes. Wash contaminated clothing before reuse. Discard contaminated shoes and clothing.
Ingestion: Seek immediate medical attention. Do not induce vomiting.
Most important symptoms and effects, both acute and delayed:
Product may hydrolyse upon contact with body fluids in the gastrointestinal tract to produce additional methanol; therefore, consider the signs/symptoms of methanol poisoning and also observe the known latency period of several days!
Indication of any immediate medical attention and special treatment needed
Hazards: No data available.
Treatment: Remove from contaminated area. Apply artificial respiration if not breathing. Get medical attention immediately.
Fire-fighting measures
General Fire Hazards: Do not use water jet as an extinguisher, as this will spread the fire. Use water spray to keep fire-exposed containers cool.
Extinguishing media
Suitable extinguishing media: Alcohol resistant foam. Carbon dioxide Dry chemical.
Unsuitable extinguishing media: Avoid water in straight hose stream; will scatter and spread fire.
Special hazards arising from the substance or mixture: Vapors are flammable and heavier than air. Vapors may travel across the ground and reach remote ignition sources causing a flashback fire danger. Ground container and transfer equipment to eliminate static electric sparks.
Advice for firefighters
Special fire fighting procedures: Keep away from sources of ignition - No smoking. Take precautionary measures against static discharges. Product may charge electrostatically during pouring or filling. All equipment used when handling the product must be grounded.
Special protective equipment for fire-fighters: Wear self-contained breathing apparatus and protective clothing.
Accidental release measures
Personal precautions, protective equipment and emergency procedures: Extinguish and do not turn on any ignition source until the area is determined to be free from fire or explosion hazards. Avoid contact with eyes, skin, and clothing. Avoid contact with liquid and vapors. Use personal protective equipment.
Environmental Precautions: Avoid discharge into drains, water courses or onto the ground.
Methods and material for containment and cleaning up: Absorb spillage with suitable absorbent material. Shovel up and place in a container for salvage or disposal.
Reference to other sections: Prevent entry into waterways, sewer, basements or confined areas.
Handling and storage
Precautions for safe handling: Do not breathe vapor/spray. Do not taste or swallow. Avoid contact with eyes, skin, and clothing. Wash hands after handling. Material can accumulate static charges which may cause an electrical spark (ignition source). Use proper bonding and/or grounding procedures.
Storage conditions: Keep away from heat, sparks and open flame. Keep container closed. Store in original container.
Conditions for safe storage, including any incompatibilities: Keep container closed.
Storage Stability: This product may be unstable.
Specific end use(s): No data available.
