Guidance on Safe Use

First-aid measures

Skin contact: Move exposed person to fresh air. Keep person warm and at rest. 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 adverse health effects persist or are severe. 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.

Ingestion: Wash out mouth with water. Move exposed person to fresh air. Keep person warm and at rest. 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.

Inhalation: Flush contaminated skin with plenty of water. Remove contaminated clothing and shoes. Continue to rinse for at least 10 minutes. Get

medical attention. In the event of any complaints or symptoms, avoid further exposure. Wash clothing before reuse. Clean shoes

thoroughly before reuse.

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.

Fire-fighting measures

Advice 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.

Fire-fighters should wear appropriate protective equipment and selfcontained breathing apparatus (SCBA) with a full face-piece

operated in positive pressure mode.

Suitable extinguishing media: Do not use water. Violent reaction may occur

Accidental release measures

Personal precautions, protective equipment and emergency procedures: No action shall be taken involving any personal risk or without

suitable training. Keep unnecessary and unprotected personnel from entering. Do not touch or walk through spilt material. Avoid

breathing vapour or mist. Provide adequate ventilation. Put on appropriate personal protective equipment.

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

Exposure controls / personal protection

Technical protection measures:

If this product contains ingredients with exposure limits, use process enclosures, local exhaust ventilation or other engineering controls to

keep worker exposure below any recommended or statutory limits.

Hygiene measures: Wash hands, forearms and face thoroughly after handling chemical products, before eating, smoking and using the lavatory and at the end of the working period. Appropriate techniques should be used to remove potentially contaminated clothing. Wash contaminated

clothing before reusing. Ensure that eyewash stations and safety showers are close to the workstation location.

Hand protection: Chemical-resistant, impervious gloves complying with an approved standard should be worn at all times when handling chemical

products if a risk assessment indicates this is necessary. After contamination with product change the gloves immediately and

dispose of them according to relevant national and local regulations <1 hours (breakthrough time): Butyl rubber - IIR , Polyvinyl chloride

Body protection: Personal protective equipment for the body should be selected based on the task being performed and the risks involved and should

be approved by a specialist before handling this product. Recommended: Wear protective clothing.

Eye protection: Safety eyewear complying with an approved standard should be used when a risk assessment indicates this is necessary to avoid

exposure to liquid splashes, mists, gases or dusts. Recommended: Tightly fitting safety goggles.

Respiratory protection: Use a properly fitted, air-purifying or air-fed respirator complying with an approved standard if a risk assessment indicates this is necessary. Respirator selection must be based on known or anticipated exposure levels, the hazards of the product and the safe

working limits of the selected respirator. Recommended: Full mask with type ABEK-P2 filter if product forms vapour/aerosol.

Stability and reactivity

Under normal conditions of storage and use, hazardous reactions

will not occur.

Conditions to avoid: Highly reactive with : alkalis , oxidising agents . Reacts violently with water, liberating ethanol ( Highly flammable ) .

With water (in a closed container), pressure will increase and create a risk of bursting.

Disposal considerations

Examine possibilities for re-utilisation. Product residues and uncleaned empty containers should be packaged, sealed, labelled,

and disposed of or recycled according to relevant national and local regulations. Where large quantities are concerned, consult the

supplier. When uncleaned empty containers are passed on, the recipient must be warned of any possible hazard that may be caused

by residues. For disposal within the EC, the appropriate code according to the European Waste List (EWL) should be used. It is

among the tasks of the polluter to assign the waste to waste codes specific to industrial sectors and processes according to the European Waste List (EWL).
