Which of the following is NOT a responsibility of the ASO?

The role of the Assistant Safety Officer (ASO) primarily revolves around ensuring safety protocols, compliance with regulations, and the health of personnel during incidents or operations. Activating Emergency Medical Services (EMS) units when exposures are identified is typically outside the ASO's responsibilities. This task usually falls under the authority of incident commanders or designated leadership roles that have the overall operational control and decision-making power during an emergency situation.

In this context, ensuring health exposure logs are maintained, advising the Hazardous Materials Supervisor on work/rest cycles, and participating in the development of the Site Safety Plan are all critical functions that contribute to maintaining a safe working environment. These actions align closely with the ASO's responsibilities to monitor and promote safety measures, establish protocols, and assist in planning and implementation for preparedness and incident response. Thus, the ASO's involvement in these areas ensures that necessary records are kept, personnel are effectively managed regarding fatigue and exposure, and comprehensive safety plans are in place, which are all fundamental for minimizing risks.
