Does your state require a bio-hazard policy? If not, I wouldn't do it.
If they do require it one of the best resources I've found is the County Health Department. When I was a school administrator we were required to have a policy and proceedures in place. The health dept furnished us with all the materials and certified me and one other administrator as trainers so we could meet the State's requirements. All at no cost!
