AUC 362/EIFS

Question 1

EIFS is exterior wall covering system that uses layered insulation and waterproofing finish..

Answer 1

can be found on commercial, pd, combustible, non combustible, etc.

Question 2

EIFS 3 layers:

Answer 2

innermost-insulation layer (foam plastic insulation )
middle-reinforcing fiberglass mesh
outermost-finish coat layer (usually cement based polymer )

-GLUED or mechanically fastened

Question 3

component of PRIMARY CONCERN during firefighting ops is

Answer 3

INNERMOST SHEATHING OF FOAM PLASTIC INSULATION –combustible , essentials thermoplastic ((1/4” to 8” thick)–hEAT RATE RELEAS 3-5 TIMES HIGHER than ordinary combustibles, such as wood or paper–if FPI is ignited, expect high heat , rapid flame spread and DENSE BLACK SMOKE

Question 4

EIFS buildings are especially vulnerable to adjacent outside fires (car rubbish, etc.) and ignition sources during construction phase (portable heater, salamanders, torches, etc.)

Answer 4

additionally , an interior fire venting out windows and doors exposing a combustible exterior wall assembly can extend rapidly consuming the exterior combustible assembly ..fire in exterior wall assembly can required significant resources to control

Question 5

RAPIDITY OF FIRE SPREAD is dependent on the THICKNESS OF THE FINISH COAT LAYER , thickness of the innermost layer (FPI) and integrity of EFIS INSTALLATION.

Answer 5

EIFS FIRS OFTEN EXTEND VIA A POORLY MAINTAINED OR DAMAGED FINISH COAT LAYER
-and advance cladding fire can further expose the contents and structural components in the interior of the building

Question 6

aesthetic design of EIFS finish coat layer makes it look like other types of building materials ..

Answer 6

WOOD FRAME STRUCTURE CALD IN EIFS can resemble brick/masonry building, this can make size up difficult

Question 7

energy efficient insulating properties of EIFS are designed to prevent heat from escaping the building..

Answer 7

these same properties can adversely affect firefighting, increasing FLASHOVER POTENTIAL/EIFS CLADDING ALONG WITH ENERGY EFFICIENT WINDOWS MAY CON\CEAL EVIDENCE OF FIRE

Question 8

ONCE FIRE penetrates the FINISH COAT LAYER , FOAM INSULATION CAN IGNITE AND RAPIDLY SPREAD

Answer 8

AS FIRE CONTINUES TO IGNITE ESCAPING MATERIAL , RESULTS IN FLAMMABLE LIQUID FIRE

Question 9

FIRST ARRIVING ENGINE consider DECK GUN

Answer 9

INITIAL HANDLINES POSITIONED FOR INTERIOR AND EXTERIOR ATTACK

-when conditions dictate , handline dedicated to exterior , number of lengths should cove all sides of building, size of line will depend on fire extent and size of building

BUILDING 3 STORIES OR HIGHER, OR A LARGE AREA BUIDLING MAY REQUIRE 2 1/2’LINE , 1 3/4 MAY BE SUFFICIENT FOR SMALLER PD

Question 10

ALL EIFS BUILDINGS ENTERED IN CIDS

Answer 10

SPECIFIC LOCATION OUTLINED (EXPOSURE 2 SIDE )

Question 11

UPON TRANSMISSION OF 10-75 FOR FIRE IN EIFS BUILDING..

Answer 11

additional engine and ladder shall be SPECIAL CALLED…TOWER LADDER IF ONE IS NOT ASSIGNED ON INITIAL ALARM

Question 12

EXTERIOR STREAM OPTIONS:

Answer 12

TL-100 PSI/135’

ENGINE DECK GUN-100 PSI /130 FEET

Question 13

A 2 1/2” with cockloft nozzle can be used to apply water to an exterior fire that is above reach of stream.

-fires in combustible wall assemblies can produce significant fire and may require large water flows to overcome heat release rate of the fire.

Answer 13

• one tip of cockloft nozzle capped with 1 1/2” shut off
• -vertical reach of up to 2 floors
• 3 feet from window sill operated at slight angle toward the building
• additional l cockloft nozzles deployed as necessary
