I cant think of any code words we use. We have an intercom system throughout the camp. We had a few emergencies over the summer but most of the campers did not hear about them because they happened during siesta. If there is a missing camper we have an air siren that goes off and everyone has to run to the field if is nasty outside then we go to the dining hall. We are divided into are cabins and units and counted. Then extra counselors are sent all over camp to search for the camper. We always have a practice drill in the beginning of the session. Last summer we did not have to do it for real thank goodness. We almost had to but we found the camper in the counselors cabin sleeping. If there is another kind of emergency it go out over the intercoms and the intercoms are in counselors rooms. Usually the counselor is able to hear it but most campers do not hear it in the cabin.
