Guidance on Safe Use
Administrative data
First-aid measures
If inhaled:
If breathed in, move person into fresh air.
If symptoms persist, call a physician.
In case of skin contact:
Take off contaminated clothing and shoes immediately.
Wash off immediately with plenty of water.
If symptoms persist, call a physician.
Wash contaminated clothing before reuse.
In case of eye contact:
Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes.
Remove contact lenses.
Consult a physician.
If swallowed:
If swallowed, rinse mouth with water (only if the person is conscious).
Call a physician immediately.
Fire-fighting measures
Suitable extinguishing media:
Use extinguishing measures that are appropriate to local circumstances and the surrounding environment.
Water mist
Dry powder
Foam
Carbon dioxide (CO2)
Sand
Aqueous film forming foam (AFFF).
Unsuitable extinguishing media: Water spray jet
Special hazards arising from the substance or mixture
Hazardous combustion products: Carbon oxides, Bromine compounds
Special protective equipment for firefighters:
Firefighters must wear fire resistant personal protective equipment. In the event of fire, wear self-contained breathing apparatus.
Further information: Avoid dust formation. In the event of fire, cool tanks with water spray
Accidental release measures
Personal precautions:
Evacuate personnel to safe areas.
Avoid breathing dust.
Avoid dust formation.
Keep away from open flames, hot surfaces and sources of ignition
Environmental precautions: Should not be released into the environment.
Methods and material for containment and cleaning up:
Keep in properly labelled containers.
Keep in suitable, closed containers for disposal.
Treat recovered material as described in the section "Disposal considerations".
Sweep up and shovel into suitable containers for disposal.
Pick up and arrange disposal without creating dust.
Handling and storage
Advice on safe handling:
Ensure all equipment is electrically grounded before beginning transfer operations.
To avoid thermal decomposition, do not overheat.
Keep away from heat and sources of ignition.
Avoid formation of dust and aerosols.
Use personal protective equipment as required.
Advice on protection against fire and explosion: Avoid dust formation
Hygiene measures: Handle in accordance with good industrial hygiene and safety practice.
Dust explosion class: St1
Requirements for storage areas and containers:
To maintain product quality, do not store in heat or direct sunlight. Store in original container. Keep containers tightly closed in a dry, cool and well-ventilated place. Keep away from heat and sources of ignition.
Recommended storage temperature: 15 - 25 °C

Exposure controls / personal protection
Engineering measures
Engineering controls should be used as the primary means to control possible exposures. Use process enclosures, local exhaust ventilation or other engineering controls to keep exposure levels below recommended exposure limits.
Personal protective equipment
Eye protection: Tightly fitting safety goggles
Hand protection: Nitrile rubber. Remarks: Impervious gloves Take note of the information given by the producer concerning permeability and break through times, and of special workplace conditions (mechanical strain, duration of contact)
Skin and body protection: closed work clothing, disposable one-piece overall
Respiratory protection:
Engineering controls should always be the primary method of controlling exposures.
If respiratory protective equipment is needed for certain activities, the type as well as the corresponding protection factor will depend upon the risk assessment and air concentrations, hazards, physical and warning properties of substances pre-sent.
Use only respiratory protection that conforms to international/ national standards.
Suitable mask with particle filter P3
Protective measures:
The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace.
Stability and reactivity
Reactivity: None reasonably foreseeable.
Chemical stability: Stable under normal conditions.
Possibility of hazardous reactions: No data available
Conditions to avoid: To avoid thermal decomposition, do not overheat. Heat, flames and sparks.
Materials to avoid: No data available
Hazardous decomposition products: HBr, Carbon oxides
Disposal considerations
Must be incinerated in a suitable incineration plant holding a permit delivered by the competent authorities.
In accordance with local and national regulations.
