78• Use a safety step or stepladder to access higher items; never standon a stool or a chair;• Store frequently used items between knee and shoulder height;• Store heavy objects on lower shelves;• Store hazardous chemicals in an area that is accessible only toauthorised laboratory workers;• Minimise quantities and container sizes kept in the laboratorycommensurate with their usage and shelf-life;• Do not store chemicals in aisles, under sinks or on floors, desks orbench tops;• Store chemicals away from sources of heat (e.g. ovens or steampipes) and direct sunlight - substances which are temperaturesensitive may require storage in a controlled temperatureenvironment with contingency plans in the event of power-failure;• Never stack bottles on top of each other;• Do not store chemicals above eye level/shoulder height;• Store larger containers on lower shelves;• Store liquids inside chemically-resistant secondary containers (suchas trays or tubs) that are large enough to hold spills, and ensure thatchemical containers and their seals or stoppers are appropriate forthe type and quantity of chemical stored (as far as is practicable,chemicals should be stored in the containers in which they aresupplied);• Containers that have held hazardous chemicals should be treated asfull, unless the receptable or package has been rendered free fromhazardous chemicals;• Store chemicals inside closable cabinets or on sturdy shelving thathas 12,7 mm - 19 mm edge guards to prevent containers from falling;• Ensure that chemicals cannot fall off the rear of shelves;• Store chemicals based on compatibility and not in alphabetical order(refer to Table 1, 2 and 3 below). 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;
• All packages in storage should be labelled to allow unmistakableidentification of the contents (see Appendix A);• Opening of packages, transferring of contents, dispensing ofchemicals or sampling should not be conducted in or on top of acabinet or a cupboard for storing chemicals unless it is specificallydesigned for this purpose and appropriate procedures and equipmentare used;• Label reactive or unstable chemicals (e.g. ethers) with the date ofreceipt and the date opened;• Inspect chemicals weekly for signs of deterioration and for labelintegrity. Leaking or damaged packages should be removed to a safearea for repacking or disposal, labels should be reattached orreplaced, as necessary, to clearly identify the contents of thepackage;• Dispose of unwanted chemicals promptly through the wastemanagement programme;• Procedures must be established to deal with clean-up and safedisposal of spillages (spill-kit should be readily accessible);• Keep inventory records of chemicals, and update annually.3. Chemical compatibilityThe storage scheme outlined in the sub-section Chemical segregationmay not suffice to prevent mixing of incompatible chemicals. Certainhazardous combinations can occur even between chemicals of the sameclassifications. Tables 1 and 2 on the following pages give examples,respectively, of which chemical groups should not be stored together, andcommon examples of incompatible chemical combinations:79
