3 - HAZARD IDENTIFICATION

Flammable, irritant.

4 - FIRST AID MEASURES

Inhalation

If overcome by vapours, remove to fresh air and if breathing stopped, give artificial respiration preferably, mouth-to-mouth.  If breathing is difficult give oxygen. Do not smoke. Obtain medical attention.

Eye contact

Flush eyes with plenty of water for at least 15 minutes. Obtain medical attention.

Skin contact

Remove contaminated clothing and shoes. Wash skin with plenty of soap and water for at least15 minutes. If irritation develops, obtain medical attention.

Ingestion

Give 1 or 2 glasses of water or milk. Do not induce vomiting. Obtain immediate medical attention.

5 -FIRE-FIGHTING MEASURES

Fire Extinguishing Agents

Water spray, carbon dioxide and dry powder

Special precautions

Evacuate enclosed areas, stay upwind. In confined space use self-contained breathing apparatus, positive pressure hose masks or airline masks (long-breathers). Use water spray to cool containers, to flush spills from source of ignition and to disperse vapours.

6 - ACCIDENTAL RELEASE MEASURES

Eliminate all ignition sources. Avoid breathing of vapours. Wear appropriate protective clothing. Keep liquid out of eyes.  Flush with large amounts of water. Contain liquid with sand or earth. Absorb with sand or non-flammable absorbent material and transfer into steel drums for recovery or disposal. Prevent liquid from entering the drains soil or groundwater.  If significant material enters surface drains inform local authorities, including fire service.

7 - HANDLING AND STORAGE

Store in the shade between 5ºC and 40ºC in a well ventilated area with adequate means of containment. All handling equipment should be electrically grounded. Keep away from heat, sparks, open flame or other sources of ignition. Avoid prolonged breathing of vapour (refer to Exposure Controls). Avoid contact with eyes, skin and clothing. Train employees on all special handling procedures before they work with this product.

8 - EXPOSURE CONTROLS / PERSONAL PROTECTION

Workplace Exposure Limits

Tetrahydrofuran 50ppm (long term) & 100ppm (short term), can be absorbed through the skin;

Methyl Ethyl Ketone (butanone) 200ppm (long term) & 300ppm (short term);

Cyclohexanone 10ppm (long term) & 20ppm (short term), can be absorbed through the skin.

NOTE: Long term = 8 hour TWA Reference period & Short term = 15 minute reference period

Respiratory Protection

Explosion proof general mechanical ventilation is recommended to maintain vapour concentrations below safe working limits. In situations where vapour concentrations exceed safe working limits, a self-contained breathing apparatus should be worn.

Hand protection

PVA coated or nitrile protective gloves

Eye Protection

Splash-proof chemical goggles

Skin Protection

Impervious apron and source of running water to wash eyes or skin in case of contact.

9 - PHYSICAL AND CHEMICAL PROPERTIES

Appearance Clear, grey, green or white, paste-like

Odour Ethereal

Boiling Point 66°C, based on first boiling point component i.e. THF

Flashpoint Minus 14ºC – based on first boiling component i.e. THF

Flammability Highly Flammable Vapour / air mixture explosive

Vapour pressure 143 mm Hg at 20°C – based on first boiling component i.e. THF

Vapour density 2.49 (Air = 1)

Specific gravity @ 20ºC 0.981 ± 0.040

Percentage volatile by volume 80-90%

Solubility in water Solvent portion completely soluble in water. Resin portion separates out.

10 - STABILITY AND REACTIVITY

Fire hazard because of low flash point and high volatility. Vapours are heavier than air and may travel to source of ignition.  Keep away from heat, sparks, open flame and other sources of ignition.

No reaction with water.

Materials to avoid

Caustics, ammonia, inorganic acids, chlorinated compounds, strong oxidants and isocyanates.

Hazardous Decomposition Products

When forced to burn, this product gives off carbon dioxide, carbon monoxide, hydrogen chloride and smoke.

11 - TOXICOLOGICAL INFORMATION

Primary routes of entry

Inhalation and skin contact.

ACUTE EFFECTS OF OVEREXPOSURE

Inhalation

Severe overexposure may result in nausea, dizziness and headache. Can cause drowsiness, irritation of eyes and nasal passages.

Skin contact

Skin irritant. Liquid contact may remove natural skin oils resulting in irritation. Dermatitis may occur with prolonged skin contact.

Skin absorption

Prolonged or widespread exposure may result in severe eye injury with conjunctival inflammation on contact with the liquid. Vapours slightly uncomfortable.

Ingestion

Moderately toxic. May cause nausea, vomiting, diarrhoea. May cause mental sluggishness.

CHRONIC EFFECTS OF OVER EXPOSURE

Symptoms of respiratory tract irritation and damage to respiratory epithelium were reported in rats exposed to 5000 ppm THF for 90 days. Elevation of SGPT suggests a disturbance in liver function. The NOEL was reported to be 200 ppm.

12 - ECOLOGICAL INFORMATION

None of the components of the preparation are classified as dangerous to the environment. However care should be taken to prevent material entering surface drains.

13 - DISPOSAL CONSIDERATIONS

Dispose of through local authorities if appropriate facilities are available, otherwise transfer to chemical disposal company.
