Properly handling chemicals is only half the job – make sure you store them safely too by doing the following:
-Properly label all chemical containers.
-Provide specific storage space for each chemical and return it after each use.
-Store volatile toxic substances and strong-smelling chemicals in a fume hood.
-Store flammable liquids in an approved flammable liquid storage cabinet.
-Separate all chemicals, especially liquids, according to compatibility groups. Also, follow all precautions regarding storage of incompatible materials and post chemical compatibility charts next to laboratories and chemical storage rooms for reference.
– Use appropriate corrosion-resistant secondary container pallets or spill-proof trays for corrosive materials to protect the cabinet and prevent leaks or spills due to breakage.
– Make sure the container is tightly sealed to prevent vapors from escaping.
-Use designated and labeled refrigerators to store chemicals. Never store flammable liquids in a refrigerator unless it is specifically designed and approved for such storage. Use only explosion-proof, non-sparking refrigerators to store flammable items.
Take care to avoid the following situations:
1. Store large and heavy containers or liquids on high shelves or cabinets.
2. Store bottles on the floor unless they are in some form of secondary container
3. Store chemicals near heat sources or in direct sunlight.
4. Store anything on top of the cupboard. There should be at least 18 inches of clearance around the sprinkler to avoid interfering with the fire suppression system.
5. Use Workbench for Storage – Workspaces should only contain chemicals that are currently in use.
6. Store chemicals indefinitely. Doing so will cause the powder to harden and the liquid to evaporate – dispose of these materials as soon as possible. It is strongly recommended that all containers be dated upon arrival at the laboratory and strictly adhere to all manufacturer’s expiration dates.
