Operational Level Lesson 2 Presentation Hazardous Materials for First Responders, 3rd Ed.

Approaching the Scene Safely Identify and evaluate problem locations and hazardous occupancies during emergency response planning. Include remote observation/assessment steps in the emergency plan. Always approach the scene from uphill, upwind, and upstream if at all possible. (1 of 2) Operational Level

Approaching the Scene Safely Use binoculars, a spotting scope, a camera lens, or a sight scope for observation. Report any unusual conditions to the telecommunications/dispatch center. Use the assessment location as a temporary staging area if reconnaissance teams must approach on foot. (2 of 2) Operational Level
