Also, considering some of the other things in my lab, a tank of inert gas is the least worrying thing that could conceivably be added. It'd be the most benign item in there, save glassware itself, clean and empty, not in use, stoppers, plastic/rubber tubing, teflon coated stirbars, teflon tape etc.
Compared to sodium, lithium and a sodium-calcium alloy by way of reactive metals, mercury metal and sometimes its salts, iodine, iodine monochloride, >98% sulfuric acid, strong aqueous ammonia solutions, phosphorus (red and white both), sometimes fuming nitric acid, sometimes although not currently concentrated perchloric acid, potassium permanganate, sodium dichromate, chromic acid/sulfuric acid mixture for cleaning at times, thionyl chloride, propionyl chloride, n-butyric anhydride, cinnamyl chloride, acetic anhydride, cyanides if ever I need them I have no issue buying some, diethyl and diisopropyl ether, THF, triphenylphosphine, hydroxylamine, methyl iodide when desired, other alkyl iodides likewise (plenty acutely toxic and carcinogenic/mutagenic) glacial acetic acid, mercaptans (thiols, where sulfur replaces oxygen in an alcohol (R-SH vs alcohols R-OH where R'=the carbon chain or cyclic aliphatic ring, notorious for their brutal stenches, a few drops of some of the lower liquid ones will be enough most likely to render an area about the size of a football pitch uninhabitable until its gone, used in miniscule traces to add to natural gas lines for house gas supplies to provide a warning stink, although in tiny quantities. As compared to hundreds of grams of dodecanethiol, which if opened outside a well-sealed glovebox would be truly heinous and way beyond sickeningly, disgustingly, gutbustingly abhorrent, a stench from the blackest abyss in hell that'd be if released all at once), ammonium polysulfides, which stink something nasty too although not so virulently foul as thiols. The abysmal stygian reek of those mercaptans/thiols CARRIES too, likewise for things like many substituted indole derivatives, which rather than the rotting egg-metallicish bitter stink of the mercaptans smell like festering shit of a particularly vile nature. Indeed, skatole, a simple ring-substituted [4-methyl indole] gives the very name of the word and etymological root 'scat' adj. 'scatological' from its being the chief culprit for what GIVES human shit its stink, then there are metal powders such as 30 micron aluminium (that is, the grain size per particle is 30 thousandths of one millimeter, plus slightly larger grain size magnesium, then there are also fine nickel and copper powders.........whats the problem about a little inert gas?
