OBJECTIVES-Recognize hazardous trench situations

-Understand risk/benefit analysis in trench rescue (rescue vs. recovery)

-Insure site safety and perimeter control

-Resources/Equipment knowledge

-Be able to initiate trench rescue actions

PURPOSE:THE PURPOSE OF THIS CLASS IS TO HELP YOU DEAL WITH A TRENCH COLLAPSE AS

AN“AWARENESS & OPERATIONS LEVEL

RESPONDER”, AS REQUIRED BYWASHINGTON STATE LAW.

THIS CLASS WILL MEET THE STANDARDS ESTABLISHED IN NFPA 1670 FOR THE

AWARENESS & OPERATIONS LEVEL RESPONDER

WHAT IS A TRENCH???

TRENCH VS. EXCAVATIONTrench:

A trench is defined as an

excavation in the ground deeper than it

is wide, but not wider than 15’ at the

base.

Excavation:

Is wider than it is deep and more than 15’ wide.

RISK/BENEFIT ANALYSIS (RESCUE OR RECOVERY)

- 1 cubic foot of soil weighs 100-150 Lbs

- 18” of soil on top of a human totals 2500-3000 Lbs

- Victims buried above the waist will asphyxiate rapidly

- RECOGNIZE WHEN THERE IS NO CHANCE FOR RESCUE!!!

INITIAL TACTICAL CONSIDERATIONS

ON SCENE--- SIZE-UP/ESTABLISH COMMAND• First arriving company officer should establish Command and

initiate a

size-up of the situation

• The first-in company should spot the apparatus at least 100’ from the

location of the trench failure. Establish staging at least 300’ from the

scene

• Complete a risk benefit analysis – RESCUE mode

• Call for resources – “Trench Rescue Response”

• Complete lock out/tag out, as applicable

(remember to assess the trench from the ends)

INITIAL COMPANY OPERATIONS-Make patient contact (again from the end of

the trench)

-place ladder/ladders

-If patient is capable, throw him/her a shovel

-secure scene

-shut off all equipment

-remove all people from the scene

-tape off scene (at least 100’)

-Gain information

-Purpose of the trench

-Number of victims

-Potential hazards

INITIAL COMPANY OPERATION (CONTINUED)

-Determine exactly what has happened

-Why were they digging (new vs. old trench)

-What time was the collapse

-How many patients

-Last known location

-Protect the patient

(If enough personnel, assign someone to stay with the patient, if not, mark patient location)

-Uncover the patient to their waist

-Provide them with head and eye protection

-Provide them with a tool to dig

-Consider oxygen

SAFETYOSHA trench shoring regulations state:

• Trench 4’ deep must have ladders every 25’

• Spoil pile not less than 1’ from lip

• Trench greater than 5’ deep, spoil pile more than 2’ from lip

• Trench greater than 4’ must have protection for workers
