137 Precautions after blast

After blasting has been carried out at a blasting site, the shotfirer or a person authorised by the shotfirer must ensure that—

(a) no one enters the blasting site until the shotfirer, or the person authorised by the shotfirer, is satisfied that any fumes and toxic gases created by the explosion are at safe levels; and

(b) the site is carefully inspected for the presence of unfired explosives or misfires, and the shotfirer, or the person authorised by the shotfirer, is satisfied that no misfires have occurred, before any further work is commenced at the site; and

(c) drilling is not undertaken at the site until—

(i) the whole of the site has been thoroughly washed down (if necessary); and

(ii) the shotfirer, or the person authorised by the shotfirer, has treated any misfire as required in the blast management plan.
