First-aid measures

Inhalation: Get medical attention immediately. 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. 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. In case of inhalation of decomposition products

in a fire, symptoms may be delayed. The exposed person may need

to be kept under medical surveillance for 48 hours.

Ingestion: Get medical attention immediately. 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. 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: Get medical attention immediately. Wash skin immediately with

plenty of water and soap. Remove contaminated clothing and shoes.

Continue to rinse for at least 10 minutes. Wash clothing before

reuse. Clean shoes thoroughly before reuse.

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: Put on appropriate personal protective equipment.

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. Do not get in

eyes or on skin or clothing. Do not ingest. Keep in the original

container or an approved alternative made from a compatible

material, kept tightly closed when not in use. Empty containers retain

product residue and can be hazardous. 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.

Conditions for safe storage, including any incompatibilities

Do not store above the following temperature: 50°C (122°F). Store

in accordance with local regulations. Store in original container

protected from direct sunlight in a dry, cool and well-ventilated area,

away from incompatible materials and food and

drink. 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.
