PURDUE UNIVERSITY Chemical Hygiene Plan and Hazardous Materials Safety Manual Laboratory Specific Plan This is the Chemical Hygiene Plan specific to the following areas: Building(s): BRWN Room Number(s): 5131, 5131A, 5131B, 5125, 5125B, 5125E, 5129, 5133, 5135 Principal Investigator (Supervisor): P.V. Ramachandran Department: Revised (Must be reviewed at least annually.): 10/15/2014 Important Telephone Numbers: 911 for All Emergencies (765) 49-48221 Purdue Police Department (Non-Emergency Line) (765) Purdue Fire Department (Non-Emergency Line) (765) 49-46371 Purdue REM (Do Not Use for an Emergency) All laboratory chemical use areas must maintain a work-area specific Chemical Hygiene Plan which conforms to the requirements of the OSHA Occupational Exposure to Hazardous Chemicals in Laboratories (29 CFR 1910.1450). Purdue University laboratories may use this document as a starting point for creating their work area specific Chemical Hygiene Plan. Minimally, this cover page is to be edited for work area specificity (non-West Lafayette laboratories are to place their own emergency, fire, and police telephone numbers in the space above) and the Purdue Chemical Hygiene Plan Awareness Certification Form must be completed for all lab employees. This instruction and information box should remain. This model Chemical Hygiene Plan is the 2014 version; the most current version can be found on the Forms page at www.purdue.edu/rem.
strategies for the labeling of research samples is discussed in Section 5.9 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 found in the SDS, primarily in Section 7, “Handling and Storage” and Section 10, “Stability and Reactivity”. If unsure of proper segregation procedures, contact the Laboratory Supervisor 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 away from bases and toxics; Storing oxidizers away from organic chemicals; and Storing reactive and acutely toxic materials away from all other chemicals. 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) 49-40121 with questions regarding chemical segregation.
