If a chemical presents more thanone hazard, segregate according to the primary hazard;• Designate specific storage areas for each class of chemical, andreturn reagents to those locations after each use. The amounts storedin laboratory areas should be kept to a minimum;• Store volatile toxic and odorous chemicals in a way that preventsrelease of vapours (e.g. inside closed secondary containers,ventilated cabinets, paraffin sealing);• Store flammables requiring refrigeration in explosion-safe orlaboratory-safe refrigerators;
