29 Laboratory Safety Manual Environmental Health and Safety • Additional requirements for specific hazardous materials are described in Section G, “Safety Practices for Specific Hazards” or may be obtained from the SDS, container label or laboratory SOP. Additional Resources • Biological Materials Inventory • Chemical Inventory • Chemical Storage Guidelines • Radioactive Materials Safety Manual • Safety Data Sheets (SDS) Safe Use of Materials Below are some general guidelines for the safe use of chemical, biological, and radiological materials: • Before use, review the hazard information found on the container label, in an SDS or equivalent (Biosafety in Microbiological and Biomedical Laboratories, Merck Index). • Follow safety precautions as specified in the approved Standard Operating Procedure (SOP). • Use the appropriate equipment for processes that release hazardous vapors, fumes, particulates, or aerosols. To determine the appropriate equipment, refer to the Chemical Fume Hoods. • Separate incompatible materials. • Do not leave hazardous processes unattended. • Do not pipette or siphon by mouth. • Do not smell or taste chemical, biological or radiological materials. • Ensure that all containers are properly closed when not in use. • Work with the minimum amount necessary for the procedure. Return excess materials to storage. • Wear appropriate personal protective equipment. Refer to “Personal Protective Equipment” in Section D, “Equipment” for more details. • Avoid working alone in the laboratory, especially if using hazardous materials. When unavoidable, make arrangements with the PI, laboratory supervisor, or a colleague to periodically check on your status. Additional requirements for specific hazardous materials are described in Section G, “Safety Practices for Specific Hazards” or may be obtained from the SDS, container label, or SOP.
