Safety Information according to GHS
Hazard Pictogram(s)
Hazard Statement(s)	H260: In contact with water releases flammable gases which may ignite spontaneously. H301: Toxic if swallowed. H314: Causes severe skin burns and eye damage. H360FD: May damage fertility. May damage the unborn child. EUH014: Reacts violently with water.
Precautionary Statement(s)	P231 + P232: Handle and store contents under inert gas. Protect from moisture. P260: Do not breathe dust. P280: Wear protective gloves/ protective clothing/ eye protection/ face protection/ hearing protection. P303 + P361 + P353: IF ON SKIN (or hair): Take off immediately all contaminated clothing. Rinse skin with water. P304 + P340 + P310: IF INHALED: Remove person to fresh air and keep comfortable for breathing. Immediately call a POISON CENTER/doctor. P305 + P351 + P338: IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. P402 + P404: Store in a dry place. Store in a closed container.
Signal Word	Danger
RTECS	ED3325000
Storage class	4.3 Hazardous materials, which set free flammable gases upon contact with water
WGK	WGK 2 obviously hazardous to water
Disposal	26 Alkali and alkaline-earth metals should be taken up in an inert solvent and neutralized by adding 2-propanol (Cat. No. 100995) dropwise with stirring. Should the reaction be more violent than expected, conversion should be carried out with tert-butanol or octanol. Caution: This reaction produces hydrogen, which can form explosive mixtures; take necessary precautions. When the reaction has ceased, add water dropwise; neutralize; container D. In the case of alkali or alkaline-earth borohydrides, add methanol (Cat. No. 106008) with stirring; in the case of alkali or alkaline-earth amides and hydrides, organoaluminium and organotin hydrides, add 2-propanol (Cat. No. 100995) dropwise. The substances, which are usually in solid form, should be previously suspended in an ether! When the respective reaction has ceased, hydrolize with water; then neutralize. Container D or E. Lithium aluminium hydride must also be destroyed by slurrying in an ether. Under an inert gas and with thorough stirring, add dropwise a 1:4 mixture of ethyl acetate (Cat. No. 822277) and the ether used to prepare the slurry. Always ensure thorough mixing (stirring)! Container A.
