11.2 Reserve pumps

It is essential that a sufficient number of stand-
by pumps are kept ready for use in plants where
failure of a pump could endanger human life or
cause damage to property or high costs.
Regular checks should be carried out to ensure
that such pumps are always ready for use (see
Point 8).
