Guidance on Safe Use
Administrative data
First-aid measures
Inhalation:
Remove to fresh air. Consult a physician after significant exposure.
Skin contact:
Wash off with soap and water. Take off all contaminated clothing immediately. Wash contaminated clothing before re-use. Obtain medical attention.
Eye contact:
Immediately flush eye(s) with plenty of water. Obtain medical attention.
Ingestion:
If conscious, drink plenty of water. Do NOT induce vomiting. Call a physician immediately.
Notes to physician
Symptoms:
Product may hydrolyze 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.
Fire-fighting measures
Suitable extinguishing media:
Alcohol-resistant foam
Carbon dioxide (CO2)
Dry chemical
Specific hazards during fire fighting:
This material is reactive with water, but the reaction will not significantly increase the fire severity.
Special protective equipment for fire-fighters:
Wear self-contained breathing apparatus and protective suit.
Further information:
Do not direct a solid stream of water or foam into hot, burning pools: this may cause frothing and increase fire intensity. Cool closed containers exposed to fire with water spray.
Accidental release measures
Personal precautions:
Avoid contact with skin, eyes and clothing. Avoid contact with liquid and vapors. Use personal protective equipment.
Environmental precautions:
Do not flush into surface water or sanitary sewer system.
Methods for cleaning up:
Soak up with inert absorbent material. Shovel into suitable container for disposal.
Handling and storage
Handling
Advice on safe handling:
Do not swallow. Avoid contact with skin, eyes and clothing. Avoid breathing vapor, aerosol and mist. Ensure adequate ventilation. Wash hands before breaks and immediately after handling the product.
Other precautions:
If mixed with water, methanol will be formed; Methanol vapors are toxic and flammable so special ventilation may be needed.
Advice on protection against fire and explosion:
Preparation may charge electrostatically: always use earthing leads when transferring from one container to another. Provide sufficient air exchange and/or exhaust in work rooms. Keep away from sources of ignition - No smoking. When using do not smoke. Do not empty into drains.
Storage
Requirements for storage areas and containers:
Keep container closed. Keep away from heat and sources of ignition. Frost sensitive from -5°C.
