"To reduce the number of spill incidents and to ensure any that happen are dealt with rapidly, you need a suitable risk assessment, as recommended in the COSHH ACoP paragraph 77 (c).
Experienced and qualified staff or specialist contractors can identify areas at risk, draw up site-specific contingency plans, recommend response, notification and waste disposal procedures, as well as helping you establish a spill responsibility hierarchy, inspection and safety review timetables and suggesting spill-control equipment appropriate to the fluids you store on site."
