While the use of various chemicals in experimental research is essential, it is also important to safely store and maintain them as a part of the Environmental, Health and Safety (EHS) program. The properties of chemicals and their reactivity vary broadly and if chemicals are not managed, stored, and labeled properly, they can have harmful or even destructive consequences such as toxic fume production, fire or explosion, which may result in human fatality, property damage or environmental hazards. Therefore, an appropriate chemical label should identify the material and list the associated hazards, and users should have knowledge of how to read chemical labels and safety data sheets (SDS). Proper chemical storage must meet OSHA (Occupational Safety and Health Association) standards and this can prevent most chemical reactivity hazards.

Procedura

1. Labeling for Hazardous Material

  1. Collect information on hazards from applicable sections of the safety data sheet (SDS) for the chemical. Some SDSs may even provide the NFPA 704 diamond symbol with hazard rating numbers filled in already.
  2. If the SDS does not provide a NFPA diamond label for the chemical, the information may be obtained under the following sections of the SDS:
    • Health hazard information under Section 11
    • Flammability information under Section 9
