Rescue personnel operating at this level will be able to perform size up and control hazards at a trench emergency. The student will be able to recognize the general hazards associated with trench and excavation emergencies and procedures necessary to evaluate these hazards. They will learn how to identify the resources necessary to conduct safe, effective trench and excavation emergency operations, as well as how to develop and implement procedures to activate the emergency response system and manage the site. Estimated teaching time 4 hours. Presentation is over 95 slides in length. Presentation is NFPA Compliant

2. GOALS
At the conclusion of this program, you will be
able to do the following
Identify the need for trench rescue
Identify the resources needed for
trench & excavation rescue
Activate a rescue response system.
Control the site & manage the scene

3. GOALS
Identify & mitigate hazards
Identify causes of collapse & common
collapse patterns
Assist with a non-entry rescue

4. HAZARDS
65% of deaths that occur in trenches are
“would be rescuers”(Onsite workers &
firefighters)
A second hazard is the “Secondary
Collapse”
Initial collapses weaken the trench side
walls
Buried utilities
Bad air quality

5. SPOIL PILE COLLAPSE
Spoils are place with in 2’ of edge & weight
causes wall to collapse

6. EXCESSIVE WATER
Water seeping into trench
walls puts the soil in
motion
Soil in motion is likely to
cave in
Seeping water is likely
caused by a broken water
or sewer line, but can be
caused by very rainy
conditions

7. DEFINITION
Supplemental shoring
Supplemental sheeting
& shoring includes
operations that
involve the placement of additional
sheeting/shoring whenever digging
exposes more than 2 feet of wall
below the bottom of the initial
strong-back

8. TIMBER SHORING
Shoring members
Uprights Cross braces
4”x6”x 14’ 8”x8”x 4’
Whalers Sheeting
8’x8’x14’ 1 1/8” plywood
¾” 14 ply thin forms

9. TRENCH SHIELD
(TRENCH BOX)
Pre-constructed set of side plates
with cross members to prevent
walls of the trench from
collapsing
Designed to withstand the forces
of the soil & protect employees
within it
It must rest not more than 2’ from floor & extend
18” above the lip

10. ESCAPE ROUTES
No more than 25’ travel
distances
Ladders are usually
used
Ladders must extend a
“few feet” above the
lip of the trench &
MUST be secured

11. VACUUM TRUCK
Vacuum truck equipment & operators can
be utilized to remove soil from the victim
before rescuers get into the trench

12. CONFINED SPACE
RESCUE TEAM
Complicated entry & extrications may utilize
confined space rescuers
