Guidance on Safe Use

First-aid measures

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.

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.

Skin contact: Flush contaminated skin with plenty of water. Remove contaminated clothing and

shoes. Continue to rinse for at least 10 minutes. Get medical attention. 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

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 vapour. In a fire or if heated, a pressure increase will

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

to sewer may create fire or explosion hazard.

pose the same hazard as the spilt product.

Handling and storage

Manufacture and use of this chemical intermediate takes place under strictly controlled conditions, as described in Art. 17/18 REACH. The substance is rigorously contained during manufacturing and use and appropriate risk management measures including PPE (i.g. during charging or sampling) are applied. Occupational exposure is reduced to a minimum and well controlled by measurements. A management system covering all general aspects of a chemical production is in place, especially cleaning and maintenance of plants and equipment. An authorisation scheme based on instructions covering the whole process ensures that only trained and authorised staff handles the substance.

Precautions for safe handling

Protective measures: Put on appropriate personal protective equipment. 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. The product

is registered with strictly controlled conditions as defined in Article 17(3) or 18(4) of

regulation (EC) no. 1907/2006 (REACH Regulation) and must therefore be handled

as such. Refer to the industry guidance prepared by Concawe/Cefic/EFCG for advice

on the confirmation of strictly controlled conditions.

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.

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 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.
