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. Flush contaminated skin with

plenty of water. 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 breathe dust. Do not

ingest. Avoid release to the environment. Use only with adequate

ventilation. Wear appropriate respirator when ventilation is

inadequate. 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: 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 well-ventilated 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.
