Distinguish which of the following states a more desirable employee evacuation accountability system, and correctly states why it is more desirable. A. Perform a simple headcount and compare the count to the employment roster. This method is more desirable because it provides a quick means of accountability, and that is key in an emergency/disaster incident. B. Perform a headcount and account for employees by comparing those present at evacuation rally points with daily attendance sheets (or other similar means/documents) that detail who was present at the facility on the given day of evacuation.
