bbattista:I like this idea and I'm working on putting this in place here too. Does anyone know where to purchase a small sign-in station that can be bolted to a wall for this purpose? I'm planning to keep a book with the policy posted, along with a log and copies of our list of hazards.
Add to the policy as to how you want visitors to respond to any facility emergency. Evacuation plans, follow your guide, etc.
In addition you should make them sign that visitor policy then issue them a card. To enter the facility they must have the card on their person.
