The
design of the sample collection system is specifically aimed at
"single use," in fact the construction is such as will
render them inoperative after one use. The materials used are
chosen to be highly suitable for destruction by incineration and
to contain no agents that would produce any toxic residue. Disposal
by this method, either in an incinerator (or a fire when used
in the field) should ensure that no infective agent is left or
passed on to any operative or passer by.
