Guidance on Safe Use
Administrative data
First-aid measures
Inhalation: Move the victim into fresh air. Get immediate medical attention.
Skin contact: Wash the skin with plenty of water and soap. Remove contaminated clothing. If irritation persists, get medical attention.
Ingestion: Flush mouth with water. Do not induce vomiting. Get immediate medical attention.
Fire-fighting measures
Extinguishing media which must not be used for safety reasons: Foam, water and CO2.
Specific hazards during fire fighting: In contact with water releases flammable gases which may ignite spontaneously (acetylene)
May emit toxic or hazardous fumes during heating or fire: CO, CO2 and CaOx.
Special protecitve equipment for fire-fighters: Use full protective clothing and a self-contained breathing apparatus.
Accidental release measures
Keep away form sources of ignition.
Methods for cleaning up: Sweep up and shovel.
Avoid dust formation.
Prevent entry into sewers.
Dispose as in ‘Disposal considerations’.
Handling and storage
This substance is handled under Strictly Controlled Conditions in accordance with REACH regulation Article 18(4) for transported isolated intermediates. Site documentation to support safe handling arrangements including the selection of engineering, administrative and personal protective equipment controls in accordance with risk-based management systems is available at the manufacturing site.
If exposure is possible:
Handle in well-ventilated space.
Avoid contact with eyes and skin. Avoid dust formation. Avoid inhalation of dust.
Handle under inert gas. Protect from moisture.
Keep away form sources of ignition.
Keep away from any possible contact with water, due to violent reaction and possibility of flash fire.
Conditions for storage
Store tightly sealed in a dry, cool and well-ventilated place.

Disposal considerations
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.
