Acid safe­guards

The Daily Telegraph - - Letters to the editor -

SIR – I agree with Adrian Waller (Let­ters, July 17) that it is il­log­i­cal that one can­not buy ni­tro­gen fer­tiliser without a li­cence, but sul­phuric acid is on sale to any­one.

Over the years I have bought sev­eral bot­tles of this acid to clear our drains, and am al­ways sur­prised that the seller has never asked for proof of iden­tity. Keep­ing a record of pur­chasers of this dan­ger­ous sub­stance is clearly not cur­rently re­quired, but per­haps it should be.

This sim­ple mea­sure might act as a de­ter­rent to would-be at­tack­ers, even if in­ves­ti­gat­ing such logs would be too labour-in­ten­sive for po­lice with their cur­rent re­sources.
