After a lot of hard work, you have your facility's emergency action plan approved by management. You have your new on-site Emergency Response Team trained and equipped and approach management to perform a full dress rehearsal drill that would involve a full day exercise because none of your ERT members have had any actual experience with emergency response activities. Management advises you that they can't have all of your ERT members out for a full day to perform in an exercise, but you can use all of them for only half of a day. Using the drills listed in your textbook, select an alternative drill that is not a field exercise to test your plan, and your responder's knowledge. Then explain why you selected that particular drill. (Choose only one of the available exercises listed in your textbook.)
