Guidance on Safe Use
Administrative data
First-aid measures
Eye contact: Wash with plenty of water for at least 15 minutes with the eyelids held open. If symptoms appears seek medical advise.
Skin contact: Remove contamined clothing. Wash with plenty of water and soap at least 15 minutes. If symptoms appears seek medical advise.
Ingestion: In sudden case, if injured person is conscious giving him large amounts of water. Do not induce vomiting. If symptoms appears seek medical advise.
Inhalation: If respiratory discomfort or irritation occurs, move the person to fresh air. If necessary give therapeutic oxygen or perform artificial respiration.
Fire-fighting measures
Suitable extinguishing media: Dry chemical, Carbon dioxide, Foam, Water spray
If it is involved in fire, it is necessary to keep the container cool using water spray.
If it is involved in fire, it may emit hydrogen fluoride fumes, hydrogen chloride fumes, nitrogen oxides and carbon oxides fumes.
Special protective equipment for fire-fighters (conform to National and European laws)
Eyes: Safety goggles
Skin: Rubber gloves
Breathing: Full face gas mask with universal filter or with organic vapour filter
Accidental release measures
Delimit contamined area, Wear adequate protective equipment. Avoid contact with skin and eyes
Environmental precautions:
Stop the spillage if the operation is not dangerous. Eliminate ignition sources and do not smoke. Do not allow the product to enter drains, surface and ground water and soil.
Pick up mechanically contamined material and put it in a suitable container for disposal. Wash area with large amounts of water.
Handling and storage
Handling: Perform in open or well ventilated areas. In close areas perform only in presence of filter ventilation systems. Avoid contact with incompatible materials and keep away from fire and ignition sources.
Storage: Store in hermetically sealed drums, protected from impacts and in a well ventilated area.
The substance is an intermediate treated under strictly controlled conditions.
The charge of row material and the production process are performed in closed cycle equipment (the product is handled through process pumps).
The only open phases are sampling and maintenance. Sampling is performed under local intake and using suitable Personal Protective Equipment; the emissions are treated in fragmentation systems. Maintenance is performed after equipment purging .
The intermediate is discharged into drums in dedicated area using local exhaust ventilation.
During all procedures the workers use the suitable PPE that are conform to European regulation and follow internal standard procedures.
The process emissions are sent to a plant for incineration. The potential environmental emissions are conveyed through pipes or local intake to an absorption plant. The liquid wastes are pre-treated and conveyed to the internal treatment plant. The eventual solid waste are sent to external treatment plant for incineration.

Exposure controls / personal protection
The adoption of the most appropriate engineering controls and Personal Protective Equipment is based on the local Risk Assessment done by the employer in its workplace conditions, particularly when a standardized exposure scenario is not available .
Protection equipment
Eyes: safety goggles or face shield
Skin: garments against chemical agents, rubber gloves and boots
Breathing: full face gas mask with universal filter or with organic vapour filter.
Emergency: self-contained breathing apparatus
Thermal hazard: Not foreseen in the standard use.
Perform in open or well ventilated areas. Do not eat or drink in work area. Do not smoke
Stability and reactivity
The substance is stable under normal conditions of use and storage.
Conditions to avoid: High temperature.
Hazardous decomposition : by heating at high temperature it decomposes with emission of toxic gas (hydrogen fluoride and chloride, carbon and nitrogen oxides).
Materials to avoid: Strong oxidizing agents, alkaline metals, halogens, sulphuric and nitric acid.
Disposal considerations
Burn in an authorized chemical incineration plant as required according to National/European laws.
Empty containers: Clean-up for re-use if permitted or send to disposal in a fully authorized plant.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
