Hazmat Operations

Hazardous Material Operations Student Study Guide

As defined by NFPA 472 an operational level responder is: An initial responder who takes Defensive control to protect: People, Environment, and property. Who is not trained in specialized clothing or equipment and does not take an offensive approach and is focused on containment.
Goal competencies at the operational level shall be to provide first responders with the knowledge and skills to perform the following what safely? APIE (Analyze, Plan, Implement, and Evaluate)
Analyze a hazardous material incident to determine the magnitude of the problem in terms of outcomes by completing the following tasks: 1) Survey the hazardous materials 2) Collect hazard and response information from the MSDS, CHEMTRAC, local/state/federal, and shipper/manufacturer. 3) Predict the likely behavior of a material and its container. 4) Estimate the potential harm at incident
Plan an initial response within the capabilities and competencies of available personnel, PPE, and control equipment by completing the following task: 1) Describe the response objectives for hazardous materials incidents 2) Describe the defensive options for a hazardous materials incident 3) Determine whether the PPE provided is appropriate for implementing each defensive option 4) ID Decon procedures.
Implement the planned response to favorably change the outcomes consistent with the LERP and the organization's SOP by completing the following: Establish and enforce scene control procedures including control zones, emergency decon, and communications. Initiate the IMS for HAZMAT incident. Don, work in, and doff PPE. Perform defensive control functions ID in plan of action.
Evaluate the progress of the actions taken to ensure that the response objectives are being met safely, effectively, and efficiently by completing the following task: Evaluate the status of the defensive actions taken in accomplishing the response objectives. Communicate the status of the planned response.
