Guidance on Safe Use

First-aid measures

Description of first aid measures

Immediately remove contaminated clothing. If danger of loss of consciousness, place patient in

recovery position and transport accordingly. Apply artificial respiration if necessary.

If inhaled:

Keep patient calm, remove to fresh air. If difficulties occur after vapour/aerosol has been inhaled,

remove to fresh air and seek medical attention.

On skin contact:

Wash thoroughly with soap and water. If symptoms persist, seek medical advice.

On contact with eyes:

Immediately wash affected eyes for at least 15 minutes under running water with eyelids held open,consult an eye specialist.

On ingestion:

Immediately rinse mouth and then drink plenty of water, do not induce vomiting, seek medical

attention.

Most important symptoms and effects, both acute and delayed

Symptoms: No significant reaction of the human body to the product known.

Hazards: No hazards anticipated.

Indication of any immediate medical attention and special treatment needed

Treatment: Treat according to symptoms (decontamination, vital functions), no known specific antidote.

Fire-fighting measures

Extinguishing media

Suitable extinguishing media:

dry powder, carbon dioxide, alcohol-resistant foam, water spray

Unsuitable extinguishing media for safety reasons: water jet

Special hazards arising from the substance or mixture

carbon monoxide, carbon dioxide

The substances/groups of substances mentioned can be released in case of fire.

Advice for fire-fighters

Special protective equipment:

Wear a self-contained breathing apparatus.

Further information:

Cool endangered containers with water-spray. Collect contaminated extinguishing water separately,

do not allow to reach sewage or effluent systems. Dispose of fire debris and contaminated

extinguishing water in accordance with official regulations.

Accidental release measures

Personal precautions, protective equipment and emergency procedures

Use personal protective clothing. Avoid inhalation. Ensure adequate ventilation. Sources of ignition

should be kept well clear.

Environmental precautions

Do not empty into drains. Do not discharge into the subsoil/soil.

Methods and material for containment and cleaning up

For large amounts: Pump off product.

For residues: Pick up with suitable absorbent material (e.g. sand, sawdust, general-purpose binder,

kieselguhr). Dispose of contaminated material as prescribed.

Handling and storage

Precautions for safe handling

Ensure thorough ventilation of stores and work areas. Adequate extraction of the vapours is necessary

when working with open containers.

Protection against fire and explosion:

Prevent electrostatic charge - sources of ignition should be kept well clear - fire extinguishers should

be kept handy. Vapours may form explosive mixture with air.

Conditions for safe storage, including any incompatibilities

Keep away from water. Segregate from acids. Segregate from foods and animal feeds.

Further information on storage conditions: Keep container tightly closed and dry; store in a cool place.

Keep container in a well-ventilated place. Protect against moisture. Protect from direct sunlight.

Protect from temperatures below: 5 °C

Protect from temperatures above: 30 °C

Exposure controls

Personal protective equipment

Respiratory protection:

Suitable respiratory protection for lower concentrations or short-term effect: Gas filter for

gases/vapours of organic compounds (boiling point >65 °C, e. g. EN 14387 Type A) Suitable

respiratory protection for higher concentrations or long-term effect: Self-contained breathing

apparatus.

Hand protection:

Chemical resistant protective gloves (EN 374)

Suitable materials also with prolonged, direct contact (Recommended: Protective index 6,

corresponding > 480 minutes of permeation time according to EN 374):

butyl rubber (butyl) - 0.7 mm coating thickness

Manufacturer's directions for use should be observed because of great diversity of types.

Eye protection:

Safety glasses with side-shields (frame goggles) (e.g. EN 166)

General safety and hygiene measures

Wearing of closed work clothing is required additionally to the stated personal protection equipment.

Avoid contact with the skin, eyes and clothing. Do not breathe vapour/spray. When using, do not eat,

drink or smoke. Hands and/or face should be washed before breaks and at the end of the shift. At the

end of the shift the skin should be cleaned and skin-care agents applied.

Disposal considerations

Waste treatment methods

Incinerate in suitable incineration plant, observing local authority regulations.

The waste codes are manufacturer's recommendations based on the designated use of the product.

Other use and special waste disposal treatment on customer's location may require different

waste-code assigments.

Contaminated packaging:

Contaminated packaging should be emptied as far as possible; then it can be passed on for recycling
