

Identify various equipment and supplies available to
the operations level responder for conducting
product control activities.
Identify fire suppression foams and equipment
available for suppressing hazardous materials fires.
Describe the proper process for developing a finish
application of fire suppression agents provided by
the AHJ.
Describe the various defensive spill control
techniques that can used for control of spills of
solids, liquids and gases.
Describe the proper role and use of remote shut-offs.

Spill Control
 Considerations
 Where
is it going?
 What is vulnerable
 Where can we stop it
 Do we have the resources

Booming
Absorbent boom




AKA: oilophilic (oil loving)
Useful for membranes on water with no current
Of little use in moving water
Containment boom (curtain)




Weighted curtain
Contain or divert product on water.
Ineffective in currents greater than three knots
entrainment or slop-over happens in faster
currents

Fire Control
 Five
questions
 What
is burning?
 Potential impacts of suppression?
 BLEVE potential?
 Harm if allowed to burn?
 Can product flow be controlled?

Application Rates
 According
to manufacturer
 Ignited spill
 Square
 Most
footage of spill time application rate
commonly
 0.10
gpm/sq foot for petroleum (<10% ETOH)
 0.16 gpm/sq foot for polar solvents
 Non-ignited
spill less required

Summary
 Control
based upon spill type
 Leak control limited to remote shut-offs at
operations level
 Fire control
 Always
controlled burn may be your best
option
