Administrative data
First-aid measures
If inhaled: Keep patient calm, remove to fresh air, seek medical attention. If breathing difficulties develop, aid in breathing and seek immediate medicaattention.
On skin contact: immediately wash thoroughly with plenty of water, apply sterile dressings, consult a skin specialist
On contact with eyes: in case of contact with the eyes, rinse immediately for at least 15 minutes with plenty of water. Immediate medical attention required
On ingestion: immediately rinse mouth and then drink plenty of water, do not induce vomiting, seek medical attention
Fire-fighting measures
Wear self-contained breathing apparatus and chemical-protective clothing
Accidental release measures
Do not discharge into drains/surface waters/groundwater

Exposure controls / personal protection
Hand protection: use flame resistant (certified to EN407) if the risk of direct, short term contact to this pyrophoric substance cannot be eliminated by the use of closed systems.
Eye protection: tightly fitting safety goggles (cage goggles) (e.g. EN 166) and face shield
Body protection: body protection must be chosen depending on activity and possible exposure, e.g. apron, protecting boots, chemical-protection suit (according to EN 14605 in case of splashes or EN ISO 13982 in case of dust). Protective clothing should be flame resistant.
Stability and reactivity
The product is stable under inert gas, Spontaneous ignition with air. Violent reactions with air and oxidizing agents. Danger of violent reaction with alcohols in the presence of acids.
Avoid all sources of ignition: heat, sparks, open flame. Avoid contact with air.
Substances to avoid: oxygen, oxidizing agents, halogenated hydrocarbons, peroxides
Hazardous decomposition products: carbon dioxide, carbon monoxide, boranes
Disposal considerations
Contaminated packaging: keep under nitrogen pressure and return to supplier as soon as possible.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
