2-methyltetrahydrofuran-3-one

Guidance on Safe Use

First-aid measures

- General advice:

When in doubt or if symptoms are observed, get medical advice. Remove victim out of the danger area. Put victim at rest, cover with a blanket and keep warm. Do not leave affected person unattended. If unconscious place in recovery position and seek medical advice.

- Following inhalation:

Remove casualty to fresh air and keep warm and at rest. If breathing is irregular or stopped, administer artificial respiration.

- Following skin contact:

Wash immediately with: Water Do not wash with: Solvents/Thinner

- Following eye contact:

In case of contact with eyes flush immediately with plenty of flowing water for 10 to 15 minutes holding eyelids apart and consult an ophthalmologist.

- Following ingestion:

If accidentally swallowed rinse the mouth with plenty of water (only if the person is conscious) and obtain immediate medical attention. Do NOT induce vomiting.

- Most important symptoms and effects: No information available.

Fire-fighting measures

- Suitable extinguishing media:

Alcohol resistant foam, extinguishing powder

- Unsuitable extinguishing media: Strong water jet, water mist

- Special hazards arising from the substance or mixture:

In case of fire may be liberated: Carbon dioxide (CO2) Carbon monoxide (CO).

- Advice for fire fighter: Do not inhale explosion and combustion gases. Use water spray jet to protect personnel and to cool endangered containers. Do not allow run-off from fire-fighting to enter drains or water courses. Wear a self-contained breathing apparatus and chemical protective clothing.

Accidental release measures

- Personal precautions, protective equipment and emergency procedures:

Special danger of slipping by leaking/spilling product. Keep away from sources of ignition. - No smoking. Do not breathe gas/fumes/vapour/spray. Provide adequate ventilation. Remove persons to safety.

- Environmental precautions:

Ensure all waste water is collected and treated via a waste water treatment plant. In case of entry into waterways, soil or drains, inform the responsible authorities.

- Methods and material for containment and cleaning up: Suitable material for taking up: Sand, kieselguhr, universal binder, sawdust. Collect in closed and suitable containers for disposal.

Handling and storage

- Precautions for safe handling:

Provide adequate ventilation as well as local exhaustion at critical locations. When using do not eat, drink, smoke, sniff. Wash hands before breaks and after work. All work processes must always be designed so that the following is as low as possible: inhalation of vapours or spray/mists. In case of entry into waterways, soil or drains, inform the responsible authorities. Use explosion-proof machinery, apparatus, ventilation facilities, tools etc. Use only antistatically equipped (spark-free) tools. Take precautionary measures against static discharges. Keep away from sources of ignition. - No smoking. Vapours can form explosive mixtures with air.

- Conditions for safe storage, including any incompatibilities: Ensure adequate ventilation of the storage area. Keep/Store only in original container. Use isolated drainage to prevent discharge to soil. Restrict access to stockrooms. Take precautionary measures against static discharges. Keep away from sources of ignition. - No smoking. Keep the packing dry and well sealed to prevent contamination and absorbtion of humidity. Never use pressure to empty container. Keep away from oxidising agent, acid and alkali.

SpecialProvisions

Exposure controls / personal protection

Control parameters

To date, no national critical limit values exist.

Exposure controls

When using do not eat, drink, smoke, sniff. Wash hands before breaks and after work.

Appropriate engineering controls

Provide adequate ventilation as well as local exhaustion at critical locations. If technical exhaust or ventilation measures are not possible or insufficient, respiratory protection must be worn.

Personal protective equipment

Eye/face protection: Eye glasses with side protection

Skin protection - hand protection: Gloves. The quality of the protective gloves resistant to chemicals must be chosen as a function of the specific working place concentration and quantity of hazardous substances. Breakthrough times and swelling properties of the material must be taken into consideration.

Skin protection - body protection: Overall

Respiratory protection: Respiratory protection necessary at: exceeding exposure limit values insufficient ventilation insufficient exhaust Handling larger quantities. Container device with compressed air (DIN EN 137) / Filtering device (full mask or mouthpiece) with filter: Filter types: A, B, E, K. Class 1: Maximum permitted contaminant concentration in inhaled air = 1000 mL/m3 (0.1 % by vol.); class 2: maximum permitted contaminant concentration in inhaled air = 5000 mL/m3 (0.5 % by vol.); class 3: maximum permitted contaminant concentration in inhaled air = 10000 mL/m3 (1.0 % by vol.)

Environmental exposure controls

Send to a hazardous waste incinerator facility under observation of official regulations.

Stability and reactivity

Reactivity, chemical stability, possibility of hazardous reactions: No information available

Conditions to avoid: Take precautionary measures against static discharges. Keep away from sources of ignition. - No smoking.

Incompatible materials: Exothermic reaction with: oxidising agent, strong acid, strong alkali

Hazardous decomposition products: Carbon dioxide. Carbon monoxide (CO).

Disposal considerations

Send to a hazardous waste incinerator facility under observation of official regulations. Clean IBCs or drums at approved facility only. Contaminated packages must be completely emptied and can be re-used following proper cleaning. Packing which cannot be properly cleaned must be disposed of. Handle contaminated packages in the same way as the substance itself.
