Chapter 3: Development of Protocols

3. Corrosive bases (e.g., QACs) 4. Corrosive acids (e.g., citric acid– or lactic acid–based disinfectants) Š Ensure that flammable and combustible liquids like alcohol-based hand sanitizers are stored properly, such as in flammable storage cabinets. The Massachusetts Fire Prevention Codes require that flammable liquids and oxidizers (e.g., bleach) be stored in separate rooms. In case of a fire, the oxidizer will feed the fire and make it worse. Š Some disinfectants (e.g., bleach) lose stability quickly after being prepared for use or stored for long periods, especially in the presence of heat or light. To maximize product stability, store products in a dark, cool location. Š Check the label for the shelf life of a product concentrate. Spill Control and Inspection Š Prepare for an incident by stocking spill clean-up supplies, including absorbents, tools, receptacles, personal protective equipment, and so forth. Š Clean up spills immediately. See the MSDS from the product distributor/manufacturer and the product label for spill-response guidelines. Š Use drip pans under spouts to catch and contain drips. Š Check containers regularly for leaks, breaks, rust, or other corrosion. If a leak or break occurs, transfer the product to another properly labeled compatible container. Shelving Š Store disinfectants in compatible containers, on compatible shelving, and with compatible products as specified on the product’s MSDS and label. These precautions are particularly important for storing bleach and quaternary compounds because they can corrode metal containers and shelving. The shelving could eventually collapse. ______________________________________________________________________________ Sources Rose, L. Massachusetts School Chemical Management Program Guide.
