It is highly recommended that TIM training classes be multi-discipline whenever possible. This is to provide prospective from other response disciplines on their goals, objectives, roles and responsibilities in an integrated response. This approach effectively provides the knowledge of where actions during the response phase can be done concurrently thus reducing the timeline for response, limiting exposure and reducing the secondary and tertiary impacts of traffic incidents.
In the Commonwealth of Massachusetts, our TIM program is institutionalized in multiple disciplines and for some required at the academy level as part of the curriculum.
