    • Who is Luse Thermal Technologies?Luse Companies started 1923. 4th generation is actively running the companyOur Primary Utility Services Include:Substation , Fossil, & Nuclear FirestoppingTransformer ProtectionPower Plant Heat Rate Recovery RepairsNuclear Mech. InsulationNuclear & Fossil Abatement
    • The Live Electric and Substation Environment WHY IS LTT QUALIFIED TO WORK IN YOUR FACILITY?LTT has installed fire protection in over 230 energizedsubstations during the past three years, withoutaccidents, injuries, or lost time incidents. Customersinclude ComEd, PG&E, PECO, DTE, Beta Steel, &Ameren to name a few. SAFETY IS LTT’s FIRST PRIORITY
    • FIRE: The uninvited guest to the dance of electrons PLANNING FOR FIRE EVENTS Proactive decisions help ensure the electrons keep flowing: ▪ Install fire protection enhancements. ▪ Learn from root cause lessons of others: When new cable is pulled, restore the fire protection system, (i.e., rebuild penetration seal). Plan for the restoration of fire protection items and schedule time for their repair, not just time to pull the new cable. Implement a periodic fire protection inspection program.
    • Planning For Fire Events FIRE: The uninvited guest to the dance of electronsUtilities are undertaking a proactive campaign to help ensure theelectrons keep flowing. Some first steps to take are: ▪ Learn from root cause lessons and review industry practices ▪ Implement a multi-year fire protection program  Passive Fire Protection  Fire Plans and Fire Department Training  Detection  Suppression

    • Cost / Benefit Ratio WHY SPEND MONEY ON FIRE PROTECTION ?LTT’s FortiFire® passive fireprotection upgrade packagewill help reduce the level ofequipment damage, outagetime to a service area, andnegative PR which can followan event.The cost of one substation fire $exceeded $7,000,000.A similar fire event in a sub-station where LTT’s turnkey Sub-station repair costspackage had been installed, after a firehelped reduce repair costs toless than $300,000.It makes sense to considerspending a little now to save a Fire Protectionlot later. upgrade costs Proactive Approach Reactive Approach
    • The Live Substation Environment SAFETY IS BUILT INTO LTT WORK PROCESS  Job Brief / Safety meeting 2 times a day  Perform "lessons learned" job critique at end of shift  Underground Electrician can be part of LTT work crew if required  Field survey spots unique design conditions prior to arrival of work crew  Hazards identified before the work starts  Use of designs and procedures, validated by years of hands-on experience  LTT installer and staff certifications include: OSHA 30 OSHA 1910.269 OSHA 1910.331-335 NFPA 70E Confined Space Entry CPR / First Aid
    • Stop - Think - Act - ReviewWORK SAFE AND SMARTRespect Equipment Zones
    • Recognizing Fire Barrier Deficiencies THE DEGRADED FIRESTOP PROBLEM Problems:Sealant degradation  Unqualified or missing penetration seals (firestops) degrade the fire rating of the floor separating the switchgear room from the basement.  Examples of degraded fireNo seal installed barriers can allow passage of fire and smoke through the floor openings, creating problems for the operation of switchgear and/or the total loss of sub-station.Unqualified design  Smoke can travel up to 420 feet per minute, making containment essential.Combustible material
    • Solutions for the Substation Basement THE UP-SIDE-DOWN APPROACH  The vast majority of Firestop Systems are designed to be installed from above the floor.  In substation basements, “above the floor” typically means inside a switch gear or bus cabinet.  LTT has worked with Hilti for three years developing sealOne of the first steps is the removal of designs as part of theunqualified sealant designs. FortiFire® system that can be efficiently installed fromDigging into the unknown requires use of underneath the floor.safety equipment, such as 12 kV ratedlineman gloves.  LTT communicates directly with Hilti Fire ProtectionLTT has developed safety protocols to remove Engineers.materials under all energized conditions

THIS EXPLAINS WHY THE FIRE BLOCKS IN THIS PHOTO HAVE BEEN INSTALLED WITH THE 5 INCH DEPTH PENETRATING THE BARRIER. FortiFire® system installed. HOLLOW CORE FLOORS REQUIRE FIRE BLOCKS TO BE INSTALLED WITH THE 8 INCH DEPTH THROUGH THE FLOOR.CUT, TRIM, PLACE AND/OR STUFF FIRE BLOCKS  INSTALLING FIRE BLOCKS AROUND PENETRANTS IS THE MOST DIFFICULT ASPECT OF THIS SEAL DESIGN. THE FULL EIGHT INCH LENGTH OF FIRE BLOCK HAS TO BE PLACED WITHIN THE HOLLOW CORE FLOOR. INSTALLATION MAY BECOME DIFFICULT AROUND THE PERIMETER OF THE OPENING WHERE A FIRE BLOCK CAN GET CAUGHT BY THE TOP OF THE HOLLOW OPENING.  LTT incorporates lessons learned LARGER PIECES ARE EASIER TO PUSH INTO POSITION, COMPARED TO SMALLER PIECES. WORK FROM ONE SIDE OF THE OPENING TO THE OTHER. PLACE THE SMALL PIECES BEFORE THE BIG PIECES. IT IS BETTER TO TRIM AND CUT A BIG PIECE THAN TO INSTALL MULTIPLE SMALL into our training programs, to continue PIECES. KEEP GAPS AS SMALL AS POSSIBLE to increase the high quality of our work.ACCURATE CUTTING OF FIRE BLOCK IS NECESSARY  SHOWS ACCURATE CUTTING OF FIRE BLOCKS ON LEFT SIDE OF EXAMPLE. AT TOP OF OPENING, SHORT PIECES OF FIRE BLOCKS WERE INSTALLED, DUE TO THE CABLES RUNNING THROUGH THE OPENING AT AN ANGLE. THIS CREATED AN OBSTRUCTION. THIS OPENING IS READY TO BE CAULKED.
    • The Substation Basement UTILIZE NEW FIRESTOP DESIGNS  Installation of firestopping in substation floor (ceiling of basement) to maintain the fire rating of the floor slab.  Firestopping work performed from underneath the floor.  Custom Hilti Firestop Designs  Trained Installation Personnel  Working safely is our first stepExample basement and fire barrier penetration seals
    • Testing is foundation of Penetration Seals TESTING FIRESTOPS  Firestops are tested to ASTM standard E814.  Test calls for temperatures of 1,000° F in first five minutes of test, climbing to 1,925° F at three hours.  Cold side temperatures are monitored during test. Test slab being removed from furnace. Notethat cable bundle in center has burned through.  After fire exposure, the test slab and seals are subjected to a powerful hose stream blast.

    • Problem Solving SEPARATING THE STAIRWAY FROM ELECTRICAL HAZARDSLTT constructed 2-hour fire rated walls around stairways, providing a safe havenand exit path for this building.This work included a 90° rotation of existing stairs to allow the construction of thenew wall in a congested area.LTT invites the opportunity to help solve problems in your facility.
    • Problem Solving DEALING WITH CHALLENGESProblem solving is part of LTT’s scope
    • POWER CABLE JOINT PROTECTION
    • Cable Splices FIRE CAUSED BY CABLE JOINT FAILUREProblem:Cable connections (joints / splices)have overheated and exploded.Loss:Fire and molten metal from cablefault knocked out adjacent cables,shutting down other power and CABLEcontrol circuits. JOINTS Circle shows area of previous joint failure. White material shows partial coverage of new EP3990 Wrap to protect adjacent cables.
    • Cable Splices POWER CABLE WRAP SOLUTION  The Power Cable Wrap solution involves wrapping the joint (plus one foot on each side) and the adjacent cables above and below the joint.  Upon exposure to fire, EP3990CABLE Wrap forms a char layer (similar toJOINTS ceramic cell structure) which helps protect the underlying cable.  This wrap is not designed to contain an arc blast.
    • CONTROL CABLE PROTECTION
    • Protect the Control CablesBURNING POWER CABLES THREATEN CONTROL CABLES Control Cables Power Cables Problem: Burning power cables have damaged control cables routed above power cables, degrading ability to operate station.
    • Protect the Control Cables EACH SUBSTATION IS DIFFERENT When burning power cables are envisioned,the hot gasses will rise and then bedeflected by the FB3600-UT Silica Cloth.This installation prevents the cable tray fromacting like a large frying pan, where thecontrol cables are cooked.Talk about cooking!This hanging pile of spaghetti will take somethought to come up with an appropriatemethod of protection.
    • Protect the Control Cables CONTROL CABLE PROTECTION  The FB3600-UT high temperature fabric provides thermal protection for control cables inside of cable tray.  Air gap between fabric and cable tray shields cables from direct flame exposure.  Cable drops / cableCABLEDROP bundles are individually covered.

    • HATCH COVER PROTECTION
    • Protecting back-up Power, the 4th element of the FortiFire® system UNPROTECTED HATCH COVERSProblem:Heat radiating through closed steelhatch cover (during basement fire)melted the battery, resulting in failureof sub-station backup power.Loss:Damage to backup power systemprevented operation of switchgear,leading to larger outage. Radiant heat through metal hatch melted and shorted out battery
    • Protecting back-up Power SOLUTION: RADIANT ENERGY SHIELDOpen hatch in process of having Closed hatch with radiant heat shield.radiant heat shield fastened tosteel plate.
    • HATCH PROTECTION Hatch Protection ACCESS HATCHES ARE DIFFERENT STYLES The size and shape of access hatches varies. A single pattern does not cover each type of hatch.
    • Hatch Protection MAY USE MULTIPLE PIECES OF BOARD1 Multiple pieces of Firestop Board may be needed to cover the underside of a hatch. Due to obstructions (opening handle, hinge, hand holds, safety barrier hinge, etc.) the entire hatch will not be completely covered.2 Only portions of this example have wrap strip installed, because steel strengthening of hatch creates two compartments.3 4 5
    • CASE STUDY FortiFire® System in Action ELECTRICAL CABINET DAMAGECABINET 12 kV cable fault explosion in electrical cabinet BULGE deformed metal covers. Fire detection system recorded two simultaneous events; one arc blast on 1st floor (in electrical cabinet) and second in basement (joint failure). Fire modeling predicted this substation to be a high risk station, so fire protection enhancements had been installed before this event took place. No injuries occurred during event or restoration work.
