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
