All hoods, glove boxes, or other essential engineering controls should be operating properly before work is started. Notify the P.D. of all incidents of exposure or spills. If appropriate precautions are not taken, personal injury or property damage may occur. Additionally, certain chemicals cannot be safely mixed or stored with other chemicals because of the danger of violent reaction or a reaction that generates toxic gas. See Appendix C for a table of incompatible chemicals.
Hazardous chemicals require that employees follow special procedures for handling and storage.
The P.D. or laboratory supervisor must create specific SOP's for unit safety. These classes give a measure of the fire risk. Appendix D lists some common flammable and combustible chemicals. Store in NFPA approved flammable liquid containers or storage cabinets, in an area isolated from ignition sources or in a special storage room designed for flammable materials. Ensure there is proper bonding and grounding when it is required, such as when transferring or dispensing a flammable liquid from a large container or drum.
