smoke. Use inert absorbent materials such as clay or sand to absorb small spillages,
shovel up and place in plastic drums for subsequent safe disposal (see section 13).
Make an earth barrier to contain large spillages and prevent spillages from entering drains
or sewers (inform the Local Water Authority if this happens) or rivers or other
watercourses (inform National Rivers Authority if this occurs).

The statutory conditions relating to the use of BLA state that :-
“Engineering control of operator exposure must be used where reasonably practicable in
addition to the following personal protective equipment:-

However engineering controls may replace personal protective equipment if a COSHH
assessment shows that they provide an equal or higher standard of protection.”
Industrial heavy duty rubber gloves are recommended or a glove providing the same
amount of protection as a minimum standard. These should be in good condition and
should be washed on both the outside and inside, after use. It is important that the fit and
