Provide covered storage off the ground away from sprinkler systems safety showers overhead water lines or condensate lines. Keep away from water taps or sinks. Store under a chemically-inert medium when appropriate stocks should be checked regularly to ensure that an adequate level of inert medium is maintained . Segregate from other flammable materials . solvents and combustibles. Use appropriate eye face protection overalls and gloves. Toxic hazards from mixtures Undesirable emissions of toxic gases may occur as a result of mixing relatively common chemicals. Refer to Table . Chemicals which are incompatible in this way must be brought into contact only under strictly controlled conditions. 230 REACTIVE CHEMICALS Table Water-sensitive chemicals consequences of water contact Acetyl bromide T Acetyl chloride T V Acetylcholine bromide T Aluminium powder F Aluminium alkyls F V Aluminium isopropoxide F Aluminium lithium hydride F Aluminium selenide T Aluminium phosphide F T Boron tribromide T Calcium granules F Calcium carbide F Calcium hydride F Calcium phosphide F T Chlorosulphonic acid T V Disulphur dichloride T V Ethoxides alkaline V Lithium metal F V Lithium aluminium deuteride F Lithium aluminium dihydride F Lithium borohydride F Lithium hydride F Lithium methoxide F .
