    • Who is The Luse Companies? Luse Companies started 1923. 4th generation is actively running the company Our Primary Utility Services Include: Substation , Fossil, & Nuclear Firestopping Transformer Protection Power Plant Heat Rate Recovery Repairs Nuclear Mech. Insulation Nuclear & Fossil Abatement
    • The Live Electric and Substation Environment Luse has installed fire protection in over 230 energized substations during the past three years, without accidents, injuries, or lost time incidents. Customers include ComEd, PG&E, PECO, DTE, Beta Steel, & Ameren to name a few. WHY IS LUSE QUALIFIED TO WORK IN YOUR FACILITY? SAFETY IS LUSE’S FIRST PRIORITY
    • FIRE: The uninvited guest to the dance of electrons 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
    • Utilities are undertaking a proactive campaign to help ensure the electrons 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 FIRE: The uninvited guest to the dance of electrons Planning For Fire Events

    • The Luse Companies ELECTRICAL SUB-STATIONS LUSE Installs Fire Protection in live 12,000 volt environment NO OUTAGE REQUIRED Dawn of LUSE FortiFire© System
    • Cost / Benefit Ratio WHY SPEND MONEY ON FIRE PROTECTION ? LUSE’s FortiFire© passive fire protection upgrade package will help reduce the level of equipment damage, outage time to a service area, and negative PR which can follow an event. The cost of one substation fire exceeded $7,000,000. A similar fire event in a sub- station where LUSE’s turnkey package had been installed, helped reduce repair costs to less than $300,000. It makes sense to consider spending a little now to save a lot later. $ Sub-station repair costs after a fire Fire Protection upgrade costs Proactive Approach Reactive Approach
    • The Live Substation Environment  Job Brief / Safety meeting 2 times a day  Perform "lessons learned" job critique at end of shift  Underground Electrician can be part of 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  LUSE staff certifications include: OSHA 30 OSHA 1910.269 OSHA 1910.331-335 NFPA 70E Confined Space Entry CPR / First Aid SAFETY IS BUILT INTO LUSE WORK PROCESS
    • Stop - Think - Act - Review WORK SAFE AND SMART Respect Equipment Zones
    • PENETRATION SEALS ARE THE LAST LINE OF DEFENSE IN A FIRE
    • Recognizing Fire Barrier Deficiencies  Unqualified or missing penetration seals (firestops) degrade the fire rating of the floor separating the switchgear room from the basement.  Examples of degraded fire 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.  Smoke can travel up to 420 feet per minute, making containment essential. THE DEGRADED FIRESTOP PROBLEM  Problems: Sealant degradation No seal installed Unqualified design Combustible material
    • Solutions for the Substation Basement  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.  LUSE has designed in conjunction with select firestop manufacturers seal designs as part of the FortiFire© system that can be efficiently installed from underneath the floor.  LUSE communicates directly with Fire Protection Engineers. THE UP-SIDE-DOWN APPROACH One of the first steps is the removal of unqualified sealant designs. Digging into the unknown requires use of safety equipment, such as 12 kV rated lineman gloves. LUSE has developed safety protocols to remove materials under all energized conditions
    • LUSE Penetration Seal Solutions LUSE FortiFire© DESIGN LIBRARY  LUSE has performed penetration seal upgrade work in over 230 substations.  This experience created a library of seal designs engineered to be installed from underneath the floor.  The LUSE library includes seal designs for different floor types, including: Hollow core floors 3 inch concrete slab 6 to 9 inch concrete slab Concrete on metal pan deck Metal floor LTT Firestop Instruction CABLES THROUGH HOLLOW CORE FLOOR OPENING SEALED FROM UNDERNEATH FLOOR FIRE RATING: 3-HOURS SMOKE SEAL: YES BARRIER TYPE: HOLLOW CORE FLOOR BARRIER LINING: CONCRETE OR STEEL BARRIER THICKNESS: 8 INCH MINIMUM OPENING SIZE: ≤ 6 INCH ROUND ANNULAR SPACE: 0" TO 3-1/2" PENETRANT(S): POWER OR CONTROL CABLES INSTALLATION INSTRUCTIONS:  HILTI FS657 FIRE BLOCKS (ITEM E) INSERT FIRE BLOCKS INTO HOLLOW CORE FLOOR. USE FULL 8" LENGTH AND PUSH BLOCK INTO THE OPENING SO IT ENTERS THE UPPER PART OF THE FLOOR (ABOVE HOLLOW ZONE). THE BOTTOM OF BLOCK SHOULD BE FLUSH WITH BOTTOM SURFACE OF OPENING. ACCURATE CUTTING OF THE FIRE BLOCK IS NECESSARY TO FIRMLY ABUT CABLES. BEVEL EDGES OF BLOCK SO NEXT BLOCK ABUTS THE PREVIOUS BLOCK.

EACH VERTICAL FIRE BLOCK MUST LINE UP WITH THE FLOOR AREA ABOVE AND BELOW THE HOLLOW ZONE. THIS IS DIFFICULT TO ACCOMPLISH BECAUSE THE BLOCK CAN GET "CAUGHT" BY THE TOP OF THE HOLLOW AREA AS THE BLOCK IS BEING PUSHED INTO THE OPENING. ACCURATE CUTTING AND PLACEMENT IS NECESSARY TO FIT RECTANGULAR SHAPED BLOCKS INTO ROUND OPENING WITH ROUND PENETRANTS.   
    • New Penetration Seal Design Drawing Format LUSE ENHANCED FortiFire® DRAWINGS  Photographs are used to describe field conditions, helping personnel to choose correct firestop design for the specific field situation.  New installation directions are based upon installing sealant from underneath the floor.  Design limitations have been expanded by sealant manufacturer to encompass expected field conditions.

    • Penetration Seal Instructions KNOWLEDGEABLE DIRECTIONS  Correct FortiFire© installation requires more than access to a firestop design drawing.  LUSE General Installation Guidelines provide expanded directions required for qualified installation. These instructions are worded so a first time installer, following the steps, will have a functioning component of the FortiFire© system installed.  LUSE incorporates lessons learned into our training programs, to continue to increase the high quality of our work. LTT Firestop InstructionGENERAL INSTALLATION GUIDELINES EXAMPLE OF INCORRECTLY INSTALLED FIRE BLOCKS  PHOTO SHOWS THE WRONG WAY TO INSTALL FIRE BLOCKS. CORRECT FIRE BLOCK INSTALLATION INCLUDES: • FIRE BLOCKS NEED FULL 8 INCH LENGTH INSTALLED VERTICALLY IN HOLLOW CORE FLOOR BARRIERS. • THE SIDES OF FIRE BLOCKS NEED TO BE ACCURATELY CUT SO THE GAPS BETWEEN ADJACENT BLOCKS ARE SMALL. • THE ENTIRE OPENING NEEDS VERTICAL FIRE BLOCKS INSTALLED. • FIRE BLOCKS ARE INSTALLED LIKE BRICK WALLS, WITH THE JOINTS STAGGERED. CAULK ALL GAPS ON UNDERSIDE. CUT FIRE BLOCKS TO CONFORM TO OPENING AND PENETRANTS STAGGER JOINTS BETWEEN FIRE BLOCKS  CORRECT FIRE BLOCK INSTALLATION PROCESS CALLS FOR JOINTS TO BE STAGGERED, SO CUT THE BLOCK IN HALF WHEN INSTALLING THE SECOND COURSE. PHOTO SHOWS AN OPTIONAL BEAD OF CAULK PLACED BETWEEN THE BLOCKS, PRIOR TO BLOCK INSTALLATION. FIRE BLOCKS ARE FRICTION FIT IN-PLACE. THIS EXAMPLE SEAL IS IN A SOLID CONCRETE FLOOR THAT IS ONLY 6 INCH THICK. THIS EXPLAINS WHY THE FIRE BLOCKS IN THIS PHOTO HAVE BEEN INSTALLED WITH THE 5 INCH DEPTH PENETRATING THE BARRIER. 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. 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 PIECES. KEEP GAPS AS SMALL AS POSSIBLE 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. FIRE BLOCK INSTALLED HORIZONTAL INSTEAD OF VERTICAL. SMALL PIECE OF FIRE BLOCK INSTALLED INSTEAD OF 8" LONG PIECE. INCOMPLETE FILL AROUND CABLES.  CUT BLOCKS ACCURATELY TO FOLLOW THE CONTOUR OF ROUND OPENINGS AND PENETRANTS. STAGGER JOINTS BETWEEN BLOCKS. APPLY CAULK TO ALL GAPS. INSTALL AS MUCH CAULK AS POSSIBLE INTO ALL GAPS. RULE: THE BIGGER THE GAP, THE DEEPER THE CAULK NEEDS TO BE INSTALLED.
    • The Substation Basement  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 LUSE/Manufacturer Firestop Designs  Trained Installation Personnel  Working safely is our first step UTILIZE NEW FIRESTOP DESIGNS Example basement and fire barrier penetration seals
    • Testing is foundation of Penetration Seals TESTING FIRESTOPS  Test slab being removed from furnace. Note that cable bundle in center has burned through.  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.  After fire exposure, the test slab and seals are subjected to a powerful hose stream blast.

White spots are concrete dust from drilling holes for mechanical fasteners.
    • Problem Solving SEPARATING THE STAIRWAY FROM ELECTRICAL HAZARDS LUSE constructed 2-hour fire rated walls around stairways, providing a safe haven and exit path for this building. This work included a 90° rotation of existing stairs to allow the construction of the new wall in a congested area. LUSE invites the opportunity to help solve problems in your facility.
    • Problem Solving DEALING WITH CHALLENGES Problem solving is part of LUSE’s scope
    • POWER CABLE JOINT PROTECTION
    • Cable Splices FIRE CAUSED BY CABLE JOINT FAILURE Problem: Cable connections (joints / splices) have overheated and exploded. Loss: Fire and molten metal from cable fault knocked out adjacent cables, shutting down other power and control circuits. Circle shows area of previous joint failure. White material shows partial coverage of new EP3990 Wrap to protect adjacent cables. CABLE JOINTS
    • 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, EP3990 Wrap forms a char layer (similar to ceramic cell structure) which helps protect the underlying cable.  This wrap is not designed to contain an arc blast. CABLE JOINTS
    • CONTROL CABLE PROTECTION
    • Protect the Control Cables Problem: Burning power cables have damaged control cables routed above power cables, degrading ability to operate station. BURNING POWER CABLES THREATEN CONTROL CABLES Power CablesPower Cables Control CablesControl Cables
    • Protect the Control Cables EACH SUBSTATION IS DIFFERENT When burning power cables are envisioned, the hot gasses will rise and then be deflected by the FB3600-UT Silica Cloth. This installation prevents the cable tray from acting like a large frying pan, where the control cables are cooked. Talk about cooking! This hanging pile of spaghetti will take some thought to come up with an appropriate method of protection.
    • Protect the Control Cables  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 / cable bundles are individually covered. CONTROL CABLE PROTECTION CONTROL CABLE PROTECTION CABLE DROP
    • 3 of the 4 FortiFire© elements INSTALLATION EXAMPLE As connections to unistrut hanger occur, the finished FortiFire© barrier system takes shape.
    • HATCH COVER PROTECTION
    • Protecting back-up Power, the 4th element of the FortiFire© system UNPROTECTED HATCH COVERS Problem: Heat radiating through closed steel hatch cover (during basement fire) melted the battery, resulting in failure of sub-station backup power. Loss: Damage to backup power system prevented operation of switchgear, leading to larger outage. Radiant heat through metal hatch melted and shorted out battery
    • Protecting back-up Power SOLUTION: RADIANT ENERGY SHIELD Open hatch in process of having radiant heat shield fastened to steel plate. Closed hatch with radiant heat shield.
    • 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 BOARD 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. Only portions of this example have wrap strip installed, because steel strengthening of hatch creates two compartments. 1 2 3 4 5 Hatch Protection
    • Transformer Cable Drop Penetrations OIL INTRUSION PROTECTION Open cable penetrations below the transformer "dog house“ can provide a path for oil, water and fire to enter the substation basement. The sealants LUSE uses to seal these openings are designed to resist oil, water and fire. Several solutions are available:
    • Cable Trough Water Mitigation Sealing THE NEED TO SEAL CABLE TROUGH Water inside of cable trough, moving toward opening in substation basement wall.  Water cascading into basement and cable tray.  Wooden board will stop a large rodent, but not water or oil.
    • Cable Trough Water Mitigation Sealing THE CABLE TROUGH SOLUTION This cable trough allowed rainwater to enter substation basement on regular basis. Shows installation of perforated PVC pipe embedded in grout dam. The drain pipe connects to station sump pump. Urethane foam was placed on top of grout. The foam allows for future cable pulling with no damage to grout dam. Side walls of trough show marks from “river” of water that flowed into substation basement.
    • Cable Trough Oil Mitigation Sealing In the event of transformer rupture, the cable trough provides a path for burning oil to enter the substation basement. The yellow arrows track the potential path of oil that can drain into the trough and then flow into the substation cable space. As of 10.12.12, no products or engineered systems reviewed have been able to 100% resolve the burning oil problem while allowing for ease of cable removal & replacement.
    • Oil Filled Equipment Hazard Within 10 feet of Building Auxiliary transformers often contain oil. During an abnormal event, oil can flow down conduits and enter the substation basement. Sealing these conduits to prevent burning oil from entering the cable space is a prudent action. Aftermath of auxiliary transformer event that propagated fire into substation basement. Oil leaked into basement following embedded conduits in concrete slab. OIL INTRUSION PROTECTION

    • New Compartments in Power Station Tunnels ELECTRIC POWER STATIONS LUSE Installs Fire Protection in live 138,000 volt environment
    • New Compartments in Power Station Tunnels  Silicone Elastomer used to seal 138 kV Cables in new fire walls.  3-hour fire rating.  Silicone elastomer provides considerable pressure resistance. FIRE AND PRESSURE RESISTANT SEALS Silicone elastomer penetration seals were originally used in nuclear plants. Project engineer specified the technology in this T&D application, due to robust nature of seal design. SILICONE ELASTOMER SEAL
    • New Compartments in Power Station Tunnels  Flexible boot seals allow for pipe movement.  3-hour fire rating.  Flexible boot seals provide considerable pressure resistance. FIRE AND PRESSURE RESISTANT SEALS Flexible boot penetration seals were also used in nuclear plants FLEXIBLE BOOT SEAL
    • Weather Protection  Silicone Sheet and Caulk provide leakage protection in concrete roof.  Weatherproof seals cover fire rated sealants installed in plane of floor.  Silicone materials provide excellent UV protection. PREVENTING WATER LEAKAGE Weather seals encapsulate 69 kV power cables as they penetrate concrete deck. Multiple electrical conduits penetrate slab
    • Structural Steel Fireproofing  Mineral wool board fireproofing eliminates adhesion problems common to spray applied fireproofing.  "Dry" material is easily installed in retrofit applications. MINERAL WOOL FIREPROOFING STEEL TRUSS IN PROCESS OF BEING COVERED
