Fire-fighting measures
Extinguishing media
· Suitable extinguishing agents:
CO2, powder or water spray. Fight larger fires with water spray or alcohol resistant foam.
· For safety reasons unsuitable extinguishing agents: Unknown.
Special hazards arising from the substance or mixture:
Formation of toxic gases is possible during heating or in case of fire.
In case of fire, the following can be released:
Nitrogen oxides (NOx)
Carbon monoxide (CO)
Carbon dioxide (CO2)
Hydrogen fluoride (HF)
Advice for firefighters:
· Protective equipment:
Wear fully protective suit.
Wear self-contained respiratory protective device.
Do not inhale explosion gases or combustion gases.
· Additional information
Collect contaminated fire fighting water separately. It must not enter the sewage system.
Dispose of fire debris and contaminated fire fighting water in accordance with official regulations.

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.
Only properly trained and authorised personnel shall handle the substance. In the case of cleaning and maintenance works, special procedures such as purging and washing shall be applied before the system is opened and entered.
Exposure controls/ personal protection
Technical measures: The substance shall be rigorously contained by technical means during its whole lifecycle including manufacture, purification, cleaning and maintenance of equipment, sampling, analysis, loading and unloading of equipment or vessels, waste disposal or purification and storage. Procedural and control technologies shall be used that minimise emission and any resulting exposure. In cases of accident and where waste is generated, procedural and/or control technologies shall be used to minimise emissions and the resulting exposure during purification or cleaning and maintenance procedures.
Organisational measures:
Only properly trained and authorised personnel shall handle the substance. In the case of cleaning and maintenance works, special procedures such as purging and washing shall be applied before the system is opened and entered.
Environmental exposure controls:
Technical measures: Emissions from ventilation or work process equipment should be checked to ensure they comply with the requirements of environmental protection legislation. In some cases, special waste water treatment, fume scrubbers, filters or engineering modifications to the process equipment will be necessary to reduce emissions to acceptable levels.
Precautions for safe handling
The product should only be handled by trained personnel.
Ensure good ventilation/exhaustion at the workplace.
Prevent formation of dust.
Information about fire - and explosion protection:
Dust can combine with air to form an explosive mixture.
Protect against electrostatic charges.
Conditions for safe storage, including any incompatibilities
· Storage:
· Requirements to be met by storerooms and receptacles:
Store only in the original receptacle.
Store in a dry, cool an well ventilated location.
· Information about storage in one common storage facility: Store away from foodstuffs.
· Further information about storage conditions:
Store in cool, dry conditions in well sealed receptacles.
Protect from heat and direct sunlight.
Protect from humidity and water.
Keep receptacle tightly sealed.
