Laboratory Risk Assessment Tool (Lab R.A.T.)


The Laboratory Risk Assessment Tool (Lab R.A.T.) provides a framework for risk assessment complimenting the process researchers already use to answer scientific questions. This tool provides a format for researchers to systematically identify and control hazards to reduce risk of injuries and incidents.

Conduct a risk assessment prior to conducting an experiment for the first time and review the Lab R.A.T. Guidelines for further details.



Boating Safety


The University of Washington has a unique blend of water-based research, academic and recreation activities. A wide range of boats support these activities, from small paddle craft to large oceanographic vessels. UW students, faculty and staff operate boats in a large variety of locations in Washington state, around the United States, and internationally. For UW vessel operators, prioritizing personal safety and stewardship for the environment is paramount.
