IBC bunds must be sited on a flat, level concrete base
Clearly label individual containers with details of what they contain and any hazard they pose;
Label storage areas with details of what can be stored in them;
Fit warning signs, for example appropriate hazardous substances symbols (pictograms), at access points to dedicated stores;
Store different materials separately so they can’t mix if there’s a leak (it’s easier to deal with a spill of just one material than a mixture); this may be a legal requirement for some substances - see information from the HSE;
Only keep the minimum working quantity of materials on site;
Protect storage from extremes in weather whenever possible, for example sunlight, frost;
Keep storage areas away, or isolated, from on site drainage, surface waters and groundwater and vehicle routes.
