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

2. 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.

Operational Level

3. 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.
