In order to avoid discharge, chemical storerooms and laboratories should not have open floor drains. Any existing floor drains should be covered to prevent discharge. Alternatively, the chemicals can be stored in an embanked area (in plastic trays/crates) to prevent discharge. For cleaning up spills, a suitable absorbent (vermiculite) should be available in sufficient quantities for the chemicals in the lab.

Fume hoods

Chemicals should not be stored in fume hoods, as bottles and other containers have a negative effect on air circulation. If there is an open drain, limited quantities may be temporarily stored, only in an embanked area. Alternatively, the drain can be plugged or flanged. Once the work is done, the chemicals should be returned to their regular storage cabinets. The lid of the fume hood should be pulled down all the way when the fume hood is not being used (if this is not done automatically), as it has a significant effect on energy use.

Transfer

All containers used to store hazardous chemicals should be labelled with the name of the product, a hazard pictogram, and information regarding whether the product may cause allergies or cancer, damage genetic material, or inhibit reproduction. Remember to use containers intended for the chemical in question. For example, corrosive chemicals should be stored in containers that can withstand this. Chemicals should be stored with lids when not in direct use, partly due to the risk of leakage, and partly due to volatile chemicals being emitted into the air.

Access

Licensed and other toxic chemical products should be stored where unauthorised personnel cannot reach them (e.g. in locked storage cabinets or locked laboratories). Other hazardous chemical products should be stored separately from products intended for human consumption. Volatile solvents should (where relevant) be stored in such a way as to prevent misuse for the purpose of intoxication.
