3.7 Tank Pits

A containment system is a basic requirement for ethylbenzene storage to:

• limit the spreading of a product spill and thus limit the flammability and environmental hazard,
• control run-off during fire fighting,
• provide a barrier against soil and groundwater contamination,
• allow spilled product to be effectively covered with foam.

An under storage leak detection system is recommended. For containment the storage size, configuration and hydraulic load due to sprinkler water and rainwater and whether foam will be the standard medium/practice for fire extinguishing should be considered. To contain the ethylbenzene in such a situation, a siphon or under-flow weir may be considered.
