Drain Covers
When a spill occurs outside, the most likely outlet for fluids to run away to are the drains. It is a legislative requirement that sufficient protection is in place for all at-risk drains. This is best met with one or more drain covers, of which three types are available. The clay drain covers are only for use in an emergency, as once moulded to the drain they cannot be re-used. Where ongoing use is anticipated, such as each time a bulk delivery is made, a polyurethane cover should be used. The neoprene cover (not illustrated) is for occasional use only.
