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

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.

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 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.

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.


GENERAL 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.

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


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.


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.

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.

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.

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.
