some thoughts 1 your custodial rate is too low they are costing you more than $15 per hour when you figure salary, benefits supervision etc. You are also charging a flat fee for their services - can they completely clean the cafeteria for $30? 2. I think a $300,000 liability limit is too low - you should talk to your insurance broker. A $1,000,000 for a single event doesn't cost very much and would provide you better coverage. Imaging 30 participants having smoke inhalation damage - $1000 a piece in medical and damages? I don't think so. 3. How do you verify that they have complied with your police and fire requirements? 4. You should get damage deposits on all AV or computer equipment used by an outside group. 5. I don't think you want anyone who has not been trained to use your lighting systems (in the auditorium) to run that equipment. I would require they hire someone from the school to make sure this stuff doesn't get broken or fall on someone and kill them (see liability limits in #2) 6. What about software usage on your computers? Can they load their own? Does that expose your system to damage, viruses, unlicensed software liability? 7. Are there sanctions for not following the rules (police, fire, tobacco etc)? Should you state that in the policy? How are you feeling - how's that killer rash doing?
