Florida Operations Level Hazardous Materials Training Unit 5.4 MISSION SPECIFIC: Leak, Spill and Fire Control

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

Florida Operations Level Hazardous Materials Training Program Spill Control q Considerations q Where is it going? q What is vulnerable q Where can we stop it q Do we have the resources

Florida Operations Level Hazardous Materials Training Program Spill Typing q Gas/Air q Dispersion, dilution, absorption q Solid/Surface q Blanketing q Liquid/Surface q Blanketing, vapor suppression q Damning, diking, diverting, retention q Liquid/Water q Over and underflow damn q Booming q Diverting q Retaining

Florida Operations Level Hazardous Materials Training Program Booming q Absorbent boom q AKA: oilophilic (oil loving) q Useful for membranes on water with no current q Of little use in moving water q Containment boom (curtain) q Weighted curtain q Contain or divert product on water. q Ineffective in currents greater than three knots q entrainment or slop-over happens in faster currents

Florida Operations Level Hazardous Materials Training Program Leak Control q Most require special training and equipment q LPG q NG q Remote shut offs

Florida Operations Level Hazardous Materials Training Program Fire Control q Five questions q What is burning? q Potential impacts of suppression? q BLEVE potential? q Harm if allowed to burn? q Can product flow be controlled?

Florida Operations Level Hazardous Materials Training Program Possible Tactics q Extinguish q Controlled burn q Protect exposures q Withdraw q Combination of these four tactics

Florida Operations Level Hazardous Materials Training Program Firefighting Foam q Material burning q Hydrocarbons q Polar q Works by q Separating q Cooling q Suppressing or smothering

Florida Operations Level Hazardous Materials Training Program Foam Characteristics q Hydrocarbon/polar solvent/multi-use q Protein/synthetic based q Expansion ratios q Re-ignition/burnback resistance q Heat resistance q Protection from freezing q Compatibility with dry chemical agents q Viscosity q Fuel shedding capability

Florida Operations Level Hazardous Materials Training Program Foam Types and Use q Protein foam 3-6% q Flouro-protein foam 3-6% q AFFF 1-3-6% q Class A foams q High Expansion (High X) foams

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

Florida Operations Level Hazardous Materials Training Program Fire Control q Exposure control q Hydrophoric materials q Sodium, Potassium q Carbides + water = acetylene q Hydrides + water = hydrogen gas q Nitrides + water = ammonia gas q Phosphides + water = phosphine gas

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

Florida Operations Level Hazardous Materials Training Program Summary q Control based upon spill type q Leak control limited to remote shut-offs at operations level q Fire control q Always controlled burn may be your best option q Fire fighting foams
