CRSP case studies
CRSP · Put your knowledge to work in context.
The CRSP® (Canadian Registered Safety Professional) credential is awarded by the Board of Canadian Registered Safety Professionals (BCRSP), an independent certifying body. According to BCRSP, it "defines and upholds professional competencies in occupational health and safety through credible credentials and standards," and the CRSP® is aimed at occupational health and safety professionals rather than technicians (the separate CRST® is the technician-level credential). The CRSP case studies are 5 cases and about 2,689 words.
