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.

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

ingest.  Do not get in eyes, on skin or clothing.  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 conditons as defined in Art 17(3) or 18(4) REACH 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.

Storage:

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.
