Guidance on Safe Use

First-aid measures

General information:

In case of accident or if you feel unwell seek medical advice (show label or SDS where possible). Effects on the skin may cause degreasing and skin irritations.

After inhalation:

Move to fresh air, keep the victim laying down and restful. If breathing has stopped, give artificial respiration.

After contact with the skin:

Wash with plenty of water or water and soap. Remove contaminated or soaked clothing. Seek medical advice in case of continuous irritation.

After contact with the eyes:

Rinse immediately with plenty of water. Follow up check by oculist.

After swallowing:

Do not induce vomiting. Danger of aspiration. Seek medical advice and clearly identify substance.

Fire-fighting measures

General information:

Fight fire from a safe distance. Cool endangered containers with water.

Suitable extinguishing media:

Use water spray (not stream) to fight fires. alcohol-resistant foam . For laboratory-standard quantities: carbon dioxide.

Extinguishing media which must not be used for safety reasons: water jet.

Special exposure hazards arising from the substance or preparation itself, combustion products, resulting gases:

At low oxygen level: acetic acid. Backfiring possible. Flammable/ explosive vapour-air mixtures may form.

Special protective equipment for fire fighting:

Use respiratory protection independent of recirculated air.

Accidental release measures

Personal precautions:

Wear personal protection equipment. Avoid contact with eyes and skin. Avoid inhaling mists and vapours.

Environmental precautions

Prevent material from entering sewers or surface waters. Contain any fluid that runs out using suitable material (e.g. earth). Dispose of in prescribed marked containers. Observe local/state/federal regulations.

Methods for cleaning up

Absorb with a liquid binding material such as diatomaceous earth and dispose of according to local/state/federal regulations. Contain larger amounts and pump up into suitable containers.

Further information:

Eliminate all sources of ignition.

Handling and storage

Handling

Precautions for safe handling:

Ensure adequate ventilation. During transfusion electrostatic charging possible. Take precautionary measures against electrostatic charging.

Precautions against fire and explosion:

Flammable vapors may accumulate and form explosive mixtures with air in containers, process vessels, including partial, empty and uncleaned containers and vessels, or other enclosed spaces. In partly emptied containers formation of explosive mixtures is possible. Take precautionary measures against electrostatic charging. Keep away from sources of ignition and do not smoke. Prevent material from entering sewage water system - danger of explosion.

Temperature class: T1

Storage

Conditions for storage rooms and vessels:

Keep container tightly closed. Store in a dry and cool place.

Advice for storage of incompatible materials:

Do not store together with fire-promoting and spontaneously inflammable substances or with highly inflammable solids.

Further information for storage:

Keep container tightly closed and store in a cool, well ventilated place. Protect against sun.

Storage class (TRGS 510): 3

3A: Flammable liquids.

General protection and hygiene measures:

Avoid exposure. Remove contaminated, soaked clothing immediately. Do not eat, drink or smoke when handling. Wash hands at the end of work and before eating. Keep away from foodstuff, drink and feedingstuff. Keep working clothes separately. Provide emergency shower and eye-bath.Avoid exposure. Remove contaminated, soaked clothing immediately.
