The purpose of the R03 grant program is (1) to develop an understanding of the risks and conditions associated with occupational diseases and injuries, (2) to explore methods for reducing risks and preventing or minimizing exposure to hazardous conditions in the workplace, and (3) to translate significant scientific findings into prevention practices and products that will effectively reduce work-related illnesses and injuries.

The NIOSH Small Research grant mechanism (R03) supports occupational safety and health research projects that can be carried out with limited resources, such as pilot and feasibility studies, secondary data analysis, or development of research methods.
