• 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 Level2–3

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. (2 of 2)
