Prior to any work-related effort, individuals are trained in laboratory safety requirements, project and field safety, and are approved by the department safety officer. For detailed information regarding general laboratory safety and protocols, refer to The University of Minnesota Department of Health and Safety Laboratory Safety Plan (see http://www.nrri.umn.edu/safety/policies.html for documentation). All project personnel are trained in sampling techniques by experienced CWE personnel, made aware of laboratory chemical inventory (Table 1), and sample or process samples only under the supervision of personnel experienced in these sampling techniques until they demonstrate proficiency.enProceduresLaboratory safetyField samplingNatural Resources Research InstituteUniversity of Minnesota DuluthTechnical Report
