labeling of research samples is discussed in Section 5.13 of the CHP. These same strategies can be used when labeling secondary chemical containers as well. Chemical Segregation All chemicals must be stored according to chemical compatibility. Once segregated by chemical compatibility, they can then be stored alphabetically. Information regarding chemical compatibility can be in the SDS, primarily in Section 7, and Storage” and Section “Handling 10, and Reactivity”. If unsure of proper segregation procedures, contact the “Stability Laboratory Supervisor or REM for assistance. Chemical segregation can be achieved by either isolation (e.g., organic solvents stored in a flammable cabinet), physical distance (e.g., acids and bases are stored on opposite sides of a chemical storage room), or secondary containment (e.g., placing oxidizing acids such as nitric acid into a secondary containment to segregate from organic acids such as formic acid as shown in Figure 5.7). In the most general terms, proper segregation can be achieved by: Storing acids away from bases and toxics; Storing oxidizers away from organic chemicals; and Storing reactive and acutely materials away from all other chemicals. Table 5.1 illustrates a more detailed chemical compatibility logic that can be used for chemical storage. Hazard classes marked by an X need to be segregated from each other (e.g., Acid, inorganic must be segregated from Base, inorganic). Contact REM at (765) 494-0121 with questions regarding chemical segregation.
