Standard Operating Guideline: Trench Rescue Operations Flashcards
A narrow excavation in relation to its length made below the surface of the ground. In general, the depth is greater than the width, but the width is not greater than 15 feet.
Trench
A man made cut, cavity, trench or depression in the earth’s surface formed by the earth removal. Usually wider than it is deep.
PER CFR 1926.652(a)(1)(ii)Excavations do not require protection if they are less than 5 feet (1.52m) in depth and examination of the ground by a competent person provides no indication of a potential cave-in.

Suffocation, extreme pressure and trauma
(a) Using the Incident Command System (ICS), the …… shall attempt to determine the following:

- How many victims are trapped and where are they located?
- Is a rescue possible or is this a body recovery?
- What kind of material is covering the victims (e.g., dirt, sand, rock)?
