I found this document online about the zoo's elephant care protocols manual and all the rules. I know it was definitely active in 2005-2004, but am unsure of how active these rules are now. This also talks about what would happen if the animals get stuck in the moat, but that is irrelevant because the moat was demolished when the exhibit was expanded a while ago. http://www.helpelephants.com/records/Roger Williams Park/RWP Elephant Management Protocols.pdf
