  2. Agrees to submit an application for the use of animals to the IACUC for any proposed use of animals in research, teaching or testing, before initiating any research project that uses animal subjects at the institution; and must wait for IACUC approval before beginning the work. 
  3. Understands that he/she must submit an amendment for any proposed changes to their protocol (including the addition of personnel) and must wait for IACUC approval before beginning the work.

  5. Ensures that all animals utilized by research staff have been approved by PAR staff (animal housing space and animal health status/vendor) and the IACUC (animal use protocol). 
  6. Declares that all experiments involving live animals will be performed under the PIs supervision or that of another qualified person listed on the protocol and that the PI has overall responsibility for laboratory personnel handling animals in laboratory and in PAR facilities.

  13. Understands it is the responsibility of the PI to ensure the safe and ethical conduct of all research conducted under this protocol, and to assure that all research is carried out following federal, state, local, and institutional policies governing animal research. 
  14. Understands that emergency veterinary care will be administered to animals showing evidence of pain or illness, in addition to routine veterinary care as prescribed for individual species. The PI understands that it is his/her responsibility to provide current and updated emergency contact information to personnel responding in an emergency in order for them to contact research personnel to assist with decision making. 
  15. The PI understands that any unanticipated adverse effects, pain or distress must be reported to the veterinarian or his/her designee. 
  16. Certifies that he/she will maintain complete, up-to-date and accessible records of procedures on animals as required by policy and regulation.
