Each laboratory must have adequate chemical storage areas that provide sufficient and defined barriers between incompatible chemicals. Information on proper chemical storage can be found in the MSDS for each chemical. Follow these guidelines when storing chemicals:
- Storage areas should be well ventilated and located away from sunlight and ignition sources.
- Chemicals should be stored in cabinets constructed of synthetic, chemically resistant materials or on metal shelving that has a one or two inch lip along the exposed edge.
- Cabinets should be easily accessible and clearly labeled as chemical storage areas.
- Chemicals should be stored below eye level.
- Solids should be stored above liquids.
- Chemicals must be segregated by chemical compatibility.
- Secondary containment should be used to segregate chemicals and contain spills.
- Chemical containers must be clearly labeled using the complete chemical name. Chemical formulas or abbreviations are not sufficient.
- Only limited quantities of chemicals should be stored in the laboratory.
- Storage areas should be inspected frequently to identify deteriorating containers and faded or missing labels.
