Overview of Hazards Involved in Working with Animals

This Environmental Health & Safety guideline documentation is intended for researchers and laboratory personnel.

Revised as of October 21, 2014

Students must be given information regarding potential hazards and zoonoses involved in working with research animals.  They must be supervised at all times.  If a risk cannot be managed, students must NOT undertake the activity.  If a student is injured during an experiment, the Teaching Assistant (TA) must be notified immediately.

Prior to any animal contact, students are encouraged to seek medical advice with their own primary care provider or the Occupational Health Nurse (303-492-6074) if they have health concerns not addressed by the instructor, or have severe allergies, asthma, are pregnant, or immunocompromised.
