Assistant Safety Officer (ASO) - In-Person Delivery
Hosted by Environmental Response Training Program (ERTP)

In-Person Assistant Safety Officer (ASO) Course

This 3-day course provides participants with course work for the position of Assistant Safety Officer (ASO). It covers the roles and responsibilities of an ASO and the relationship of the ASO to the Safety Officer (SO) within the Incident Command System (ICS). The student will review the administrative functions of the SO (e.g., participating Incident Management Team meetings and incident briefings, and conducting investigations) but the real emphasis will be on how to be the “eyes and ears” of the SO in the field. This training is designed to provide the ASO with a better understanding of field operations to help ensure the smooth flow of information between the field and Incident Command. This, in turn, helps improve the efficiency and safety of field operations, and decreases the likelihood of injuries and "stop work" orders.

Instructional methods include lectures, videos, class discussions, and group exercises. A certificate of course completion will be awarded to those students who have 100% attendance.
