Tetrahydro-2-methylfuran

Guidance on Safe Use

First-aid measures

Eye contact

Immediately flush eyes with plenty of water, occasionally lifting the upper and lower

eyelids. Check for and remove any contact lenses. Continue to rinse for at least 10

minutes. Get medical attention.

Inhalation

Remove victim to fresh air and keep at rest in a position comfortable for breathing. If

it is suspected that fumes are still present, the rescuer should wear an appropriate

mask or self-contained breathing apparatus. If not breathing, if breathing is irregular

or if respiratory arrest occurs, provide artificial respiration or oxygen by trained

personnel. It may be dangerous to the person providing aid to give mouth-to-mouth

resuscitation. Get medical attention. If necessary, call a poison center or physician.

If unconscious, place in recovery position and get medical attention immediately.

Maintain an open airway. Loosen tight clothing such as a collar, tie, belt or waistband.

Skin contact

Flush contaminated skin with plenty of water. Remove contaminated clothing and

shoes. Get medical attention if symptoms occur. Wash clothing before reuse. Clean

shoes thoroughly before reuse.

Ingestion

Wash out mouth with water. Remove dentures if any. Remove victim to fresh air and

keep at rest in a position comfortable for breathing. If material has been swallowed

and the exposed person is conscious, give small quantities of water to drink. Stop if

the exposed person feels sick as vomiting may be dangerous. Do not induce vomiting

unless directed to do so by medical personnel. If vomiting occurs, the head should be

kept low so that vomit does not enter the lungs. Get medical attention if adverse

health effects persist or are severe. Never give anything by mouth to an unconscious

person. If unconscious, place in recovery position and get medical attention

immediately. Maintain an open airway. Loosen tight clothing such as a collar, tie, belt

or waistband.

Protection of first-aiders

No action shall be taken involving any personal risk or without suitable training. If it is

suspected that fumes are still present, the rescuer should wear an appropriate mask

or self-contained breathing apparatus. It may be dangerous to the person providing

aid to give mouth-to-mouth resuscitation.

Fire-fighting measures

Extinguishing media

Suitable extinguishing media

Use dry chemical, CO2, water spray (fog) or foam.

Unsuitable extinguishing media

Do not use water jet.

Special hazards arising from the substance or mixture

Hazards from the substance or mixture

Highly flammable liquid and vapor. In a fire or if heated, a pressure increase will

occur and the container may burst, with the risk of a subsequent explosion. The

vapour/gas is heavier than air and will spread along the ground. Vapours may

accumulate in low or confined areas or travel a considerable distance to a source of

ignition and flash back. Runoff to sewer may create fire or explosion hazard. May

form explosive peroxides.

Hazardous combustion products

Decomposition products may include the following materials:

carbon dioxide

carbon monoxide

Advice for firefighters

Special precautions for firefighters

Promptly isolate the scene by removing all persons from the vicinity of the incident if

there is a fire. No action shall be taken involving any personal risk or without suitable

training. Move containers from fire area if this can be done without risk. Use water

spray to keep fire-exposed containers cool.

Special protective equipment for fire-fighters

Fire-fighters should wear appropriate protective equipment and self-contained

breathing apparatus (SCBA) with a full face-piece operated in positive pressure mode.

Clothing for fire-fighters (including helmets, protective boots and gloves) conforming

to European standard EN 469 will provide a basic level of protection for chemical

incidents.

Accidental release measures

Personal precautions, protective equipment and emergency procedures

For non-emergency personnel

No action shall be taken involving any personal risk or without suitable training.

Evacuate surrounding areas. Keep unnecessary and unprotected personnel from

entering. Do not touch or walk through spilt material. Shut off all ignition sources. No

flares, smoking or flames in hazard area. Avoid breathing vapour or mist. Provide

adequate ventilation. Wear appropriate respirator when ventilation is inadequate. Put

on appropriate personal protective equipment.

For emergency responders

If specialised clothing is required to deal with the spillage, take note of any information

in Section 8 on suitable and unsuitable materials. See also the information in "For

non-emergency personnel".

Environmental precautions

Avoid dispersal of spilt material and runoff and contact with soil, waterways, drains

and sewers. Inform the relevant authorities if the product has caused environmental

pollution (sewers, waterways, soil or air).

Methods and materials for containment and cleaning up

Small spill

Stop leak if without risk. Move containers from spill area. Dilute with water and mop

up if water-soluble. Alternatively, or if water-insoluble, absorb with an inert dry

material and place in an appropriate waste disposal container. Use spark-proof tools

and explosion-proof equipment. Dispose of via a licensed waste disposal contractor.

Large spill

Stop leak if without risk. Move containers from spill area. Approach the release from

upwind. Prevent entry into sewers, water courses, basements or confined areas.

Wash spillages into an effluent treatment plant or proceed as follows. Contain and

collect spillage with non-combustible, absorbent material e.g. sand, earth, vermiculite

or diatomaceous earth and place in container for disposal according to local

regulations (see section 13). Use spark-proof tools and explosion-proof equipment.

Dispose of via a licensed waste disposal contractor. Contaminated absorbent

material may pose the same hazard as the spilt product. Note: see section 1 for

emergency contact information and section 13 for waste disposal.

Handling and storage

Precautions for safe handling

Protective measures

Put on appropriate personal protective equipment (see Section 8). Do not ingest.

Avoid contact with eyes, skin and clothing. Avoid breathing vapour or mist. Use only

with adequate ventilation. Wear appropriate respirator when ventilation is inadequate

Do not enter storage areas and confined spaces unless adequately ventilated. Keep

in the original container or an approved alternative made from a compatible material,

kept tightly closed when not in use. Store and use away from heat, sparks, open

flame or any other ignition source. Use explosion-proof electrical (ventilating, lighting

and material handling) equipment. Use only non-sparking tools. Take precautionary

measures against electrostatic discharges. Empty containers retain product residue

and can be hazardous. Do not reuse container.

Advice on general occupational hygiene

Eating, drinking and smoking should be prohibited in areas where this material is

handled, stored and processed. Workers should wash hands and face before eating,

drinking and smoking. Remove contaminated clothing and protective equipment

before entering eating areas. See also Section 8 for additional information on hygiene

measures.

Conditions for safe storage, including any incompatibilities

Store in accordance with local regulations. Store in a segregated and approved area.

Store in original container protected from direct sunlight in a dry, cool and wellventilated

area, away from incompatible materials (see section 10) and food and

drink. Store locked up. Eliminate all ignition sources. Separate from oxidizing

materials. Keep container tightly closed and sealed until ready for use. Containers

that have been opened must be carefully resealed and kept upright to prevent

leakage. Do not store in unlabelled containers. Use appropriate containment to

avoid environmental contamination.
