Unit 5.4MISSION SPECIFIC:Leak, Spill and Fire Control
Florida Operations LevelHazardous Materials Training Program
Objectives 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 vulnerableWhere can we stop itDo we have the resources
Florida Operations LevelHazardous Materials Training Program
Spill Typing Gas/Air
Dispersion, dilution, absorption Solid/Surface
Blanketing Liquid/Surface
Blanketing, vapor suppression Damning, diking, diverting, retention
Liquid/Water Over and underflow damn Booming Diverting Retaining
Florida Operations LevelHazardous Materials Training Program
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

Leak Control Most require special training and
equipmentLPGNGRemote shut offs
Florida Operations LevelHazardous Materials Training Program
Fire Control Five questions
What is burning?Potential impacts of suppression?BLEVE potential?Harm if allowed to burn?Can product flow be controlled?
Florida Operations LevelHazardous Materials Training Program
Possible Tactics Extinguish Controlled burn Protect exposures Withdraw Combination of these four tactics
Florida Operations LevelHazardous Materials Training Program
Firefighting Foam Material burning
Hydrocarbons Polar
Works by Separating Cooling Suppressing or smothering
Florida Operations LevelHazardous Materials Training Program
Foam Characteristics Hydrocarbon/polar solvent/multi-use Protein/synthetic based Expansion ratios Re-ignition/burnback resistance Heat resistance Protection from freezing Compatibility with dry chemical agents Viscosity Fuel shedding capability
Florida Operations LevelHazardous Materials Training Program
Foam Types and Use Protein foam 3-6% Flouro-protein foam 3-6% AFFF 1-3-6% Class A foams High Expansion (High X) foams
Florida Operations LevelHazardous Materials Training Program
Application Rates According to manufacturer Ignited spill
Square footage of spill time application rate Most commonly
0.10 gpm/sq foot for petroleum (<10% ETOH)0.16 gpm/sq foot for polar solvents
Non-ignited spill less required

Fire Control Exposure control
Hydrophoric materials Sodium, Potassium Carbides + water = acetylene Hydrides + water = hydrogen gas Nitrides + water = ammonia gas Phosphides + water = phosphine gas

Fire Control Withdrawal
BLEVE potential Fires involving explosives Unacceptable risks Overwhelming conditions No win scenarios
Florida Operations LevelHazardous Materials Training Program
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
