2.3.7 Containment

To limit the flammability, exposure and environmental hazards, every effort must be made to contain spilled material. Therefore, in the engineering phase, a bund and optionally a remote emergency containment system should be provided for the storage tank and unloading station, to achieve a limited evaporation surface, better foam effectiveness and improved run-off control of contaminated fire and sprinkler water. Overflow of hydrocarbons such as ethylbenzene from bunds due to addition of fire water can be avoided by installing an underflow weir or siphon.

The local Water Authority should be advised if the spillage has entered a water course or external drainage system.
