A standard operating procedure (SOP) is a set of written instructions that describes, in detail, how to perform a laboratory process or experiment safely and effectively. Labs must have written SOPs when work involves the use of hazardous materials (chemical, radioactive, and biological) or physical hazards. 

SOP Development

Principal Investigators or supervisors are responsible for ensuring that accurate SOPs are developed and implemented in their lab. For assistance, see the SOP Development page. The EH&S SOP template contains relevant health and safety sections. 

SOP Library

EH&S has compiled a list of SOPs created and shared by ISU researchers. SOPs in the online SOP Library can be used by ISU researchers in the development of their own SOPs. Since each lab is different, researchers will need to edit the SOPs with information specific to their lab operation.
