Florida Operations Level Hazardous Materials Training

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

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

Firefighting Foam Material burning

Hydrocarbons Polar

Works by Separating Cooling Suppressing or smothering

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

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
