Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

First-aid measures
Description of first aid measures:
- Not specifically necessary: observance of good industrial hygiene is recommended.
- Most important symptoms and effects, both acute and delayed: no episodes of damage to health ascribable to the product have been reported.
- Indication of any immediate medical attention and special treatment needed: information not available.
Fire-fighting measures
- Extinguishing media:
SUITABLE EXTINGUISHING EQUIPMENT: the extinguishing equipment should be of the conventional kind: carbon dioxide, foam, powder and water spray.
UNSUITABLE EXTINGUISHING EQUIPMENT: none in particular.
- Special hazards arising from the substance or mixture:
HAZARDS CAUSED BY EXPOSURE IN THE EVENT OF FIRE: do not breathe combustion products. The product is combustible and, when the powder is released into the air in sufficient concentrations and in the presence of a source of ignition, it can create explosive mixtures with air. Fires may start or get worse by leakage of the solid product from the container, when it reaches high temperatures or through contact with sources of ignition.
- Advice for firefighters:
GENERAL INFORMATION: use jets of water to cool the containers to prevent product decomposition and the development of substances potentially hazardous for health. Always wear full fire prevention gear. Collect extinguishing water to prevent it from draining into the sewer system. Dispose of contaminated water used for extinction and the remains of the fire according to applicable regulations.
SPECIAL PROTECTIVE EQUIPMENT FOR FIRE-FIGHTERS: normal fire fighting clothing i.e. fire kit (BS EN 469), gloves (BS EN 659) and boots (HO specification A29 and A30) in combination with self-contained open circuit positive pressure compressed air breathing apparatus (BS EN 137).
Accidental release measures
- Personal precautions, protective equipment and emergency procedures: use breathing equipment if fumes or powders are released into the air. These indications apply for both processing staff and those involved in emergency procedures.
- Environmental precautions: the product must not penetrate into the sewer system or come into contact with surface water or ground water.
- Methods and material for containment and cleaning up: confine using earth or inert material. Collect as much material as possible and eliminate the rest using jets of water. Contaminated material should be disposed of in compliance with the provisions set forth in disposal considerations.
Handling and storage
- Precautions for safe handling: before handling the product, consult all the other sections of this material safety data sheet. Avoid leakage of the product into the environment. Do not eat, drink or smoke during use.
- Conditions for safe storage, including any incompatibilities: keep the product in clearly labelled containers. Keep containers away from any incompatible materials, see section stability and reactivity.
- Specific end use(s): information not available.

Exposure controls / personal protection
- Control parameters: during the risk assessment process, it is essential to take into consideration the ACGIH occupational exposure levels for inert particulate otherwise classified (PNOC respirable fraction: 3 mg/m3; PNOC inhalable fraction: 10 mg/m3). For values above these limits, use a P type filter, whose class (1, 2 or 3) must be chosen according to the outcome of risk assessment. TLV of solvent mixture: 10 mg/m3.
- Exposure controls: comply with the safety measures usually applied when handling chemical substances.
HAND PROTECTION: none required.
SKIN PROTECTION: none required.
EYE PROTECTION: none required.
RESPIRATORY PROTECTION: use a type P filtering facemask (see standard EN 149) or equivalent device, whose class (1, 2 or 3) and effective need, must be defined according to the outcome of risk assessment.
ENVIRONMENTAL EXPOSURE CONTROLS: the emissions generated by manufacturing processes, including those generated by ventilation equipment, should be checked to ensure compliance with environmental standards.
Stability and reactivity
- Reactivity: there are no particular risks of reaction with other substances in normal conditions of use.
- Chemical stability: the product is stable in normal conditions of use and storage.
- Possibility of hazardous reaction: no hazardous reactions are foreseeable in normal conditions of use and storage.
- Conditions to avoid: none in particular. However the usual precautions used for chemical products should be respected.
- Incompatible materials: information not available.
- Hazardous decomposition products: information not available.
Disposal considerations
Waste treatment methods: reuse, when possible. Neat product residues should be considered special non-hazardous waste. Disposal must be performed through an authorised waste management firm, in compliance with national and local regulations. Solid residues may be suitable for disposal in an authorised landfill site.
CONTAMINATED PACKAGING: contaminated packaging must be recovered or disposed of in compliance with national waste management regulations.
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.
