6 Module 1: Introduction To Fire Safety This lesson describes the definitions and benefits from the application of fire rated glazings.

7 I. Introduction To Fire Safety Specific Terms and Labels Definitions from the IBC Fire-Resistance: A fire-resistant material blocks the flow of radiant heat emitted from a fire Fire-Protection: A fire-protected material has an increased chance of surviving and maintain integrity during a fire, not to block heat emitted from a fire as with fire-resistance materials Fire-Resistance Rating: Refers to the period of time a component maintains the ability to confine a fire

8 I. Introduction To Fire Safety Specific Terms and Labels IBC 2006 requires all fire rated glazings to be permanently labeled with the following: Doors (D): NFPA 252 Openings (O): NFPA 257 Walls (W): ASTM E119, NFPA 251 Hose Stream Test: H if passes, NH if fails Temperature Rise: T if passes, NT if fails Fire Rating in Minutes: XXX (60 for 60 min)

9 I. Introduction To Fire Safety The Effect of Heat on Glass Temperature (T) C The Standard Temperature/Time Curve Tempered glass softens and slumps from frame Tempered glass looses tempered properties Tempered glass becomes vulnerable to temperature differentials Vinyl in PVB-laminated glass begins to melt & glass falls from frame Uneven heating will cause annealed glass to crack & fall from the frame Time (t) min.

10 I. Introduction To Fire Safety Benefits of using Fire-Rated Glass Why Use Fire-Rated Glazing? It provides adequate means of escape for occupants Allow safe access for fire-fighters and rescue teams To prevent the spread of fire throughout the building Fire-Rated Glazing can protect important means of egress from fire while people escape and firefighters enter.

11 I. Introduction To Fire Safety Fire Safety in Buildings Safeguard Methods Detection: Smoke, heat, and carbon monoxide detectors and fire alarms Suppression: Sprinklers, fire-extinguishers, specialty hoses, dry chemical foam, gaseous extinguishing agents Compartmentation: Isolating zones of a building to prevent the spread of fire, utilized as passive fire protection Building Occupant Emergency Education: The occupants must know the escape plan

12 Module 2: Fire-Protection Glass This lesson defines the various types of fire protection glazing.

13 II. Fire-Protection Glass Varieties of Fire-Protection Glass Types of Fire-Protection glazing include: Wired Glass Ceramic Glass with Intumescent Laminates

14 II. Fire-Protection Glass Varieties of Fire-Protection Glass Wired Glass/Ceramic Fire-Rated Glass Wire Glass Resists the passage of flames and smoke Weaker than tempered/laminated glass Does not however, meet human impact safety code requirements Ceramic Fire-Rated Glazing Ceramic fire-rated glass resists thermal shock Available in insulated units for exterior applications Does not provide a barrier to heat.

15 II. Fire-Protection Glass Varieties of Fire-Protection Glass Glass with Intumescent Laminate Intumescent interlayer provides an opaque barrier to flames, smoke, and hot gasses Provides 20 minutes of fire protection, stays in place when used with an approved fire protection rated framing assembly Resists thermal shock caused by sprinklers and hoses

16 II. Fire-Protection Glass Varieties of Fire-Protection Glass Glass with Intumescent Laminate Intumescent Interlayer Designed for use in Fire Protection doors in wood and steel

17 II. Fire-Protection Glass Comparison of Surface Temperatures

18 Module 3: Fire-Resistance Glass This lesson explains fire resistance glass, and how the technology works.

19 III. Fire-Resistance Glass Uses and Features Fire-Resistance Glass Lowers Heat Radiation Levels Blocks the heat radiation to acceptable low levels Importance increases with size of glazed area

20 III. Fire-Resistance Glass Uses and Features Features of Fire-Resistant Glass Variety of sizes, thicknesses and combinations offering superb design flexibility and aesthetics Can be combined with Low-E glass, solar control glass, acoustic laminated glass, tempered and laminated glass Ideal for windows, walls, doors, transoms, partitions, facades and even sloped glazing applications

21 III. Fire-Resistance Glass Uses and Features Fire-Resistance Glazing Wall Standard ASTM E-119 (IBC), UL 263, NFPA 251 Includes the hose stream test and temperature rise

22 III. Fire-Resistance Glass Multi-Layer Intumescent Laminate Technology History Developed in Germany over 25 years ago Considerable research and development efforts Offers highest level of fire and impact safety

23 III. Fire-Resistance Glass Multi-Layer Intumescent Laminate Technology Properties Made with multi-layers of glass and sodium silicate interlayers At 150 F, an opaque foam forms which creates a barrier against heat, smoke and flames Depending on the product chosen, fire ratings range from 45, 60, 90, and 120 minutes

24 III. Fire-Resistance Glass Multi-Layer Intumescent Laminate Technology Interlayers create an opaque insulating shield View from the protected side of the thermally insulated system while the other side is exposed to a furnace.

25 Module 4: Testing Fire-Resistance Glass This lesson demonstrates how fire resistance glass is tested and describes the industry standards used when testing.

26 IV. Testing Fire-Resistance Glass Procedures Fire-Resistant systems must be tested according to the test standards established for windows, doors, and walls The fire test must include the hose stream test, which must also be performed by an independent laboratory Building codes require that only listed products can be used in building applications

27 IV. Testing Fire-Resistance Glass Timed Fire Test Fire Test After One Minute Fire test begins when the furnace burner ignites Interlayer begins to intumesce Glass will slowly turn opaque

28 IV. Testing Fire-Resistance Glass Timed Fire Test Examples of a fire test after 10, 30, and 60 minutes After 10 minutes test time After 30 minutes test time After 60 minutes test time

29 IV. Testing Fire-Resistance Glass Timed Fire Test The Standard Temperature/Time Curve The thermal insulation is so effective at blocking radiant heat that the other side of the glass can be touched without burning skin.

30 IV. Testing Fire-Resistance Glass Testing Fire-Resistant Glass Fire Test Considerations Approved by an accepted testing institute Part of an approved Fire-Resistant rated framing assembly Must be glazed correctly

31 IV. Testing Fire-Resistance Glass Timed Hose Stream Test Examples from the hose stream test Hose Stream Test Begins Hose Stream Test Almost Complete After 60 minutes test time and the hose stream test

32 IV. Testing Fire-Resistance Glass Testing Fire-Resistant Glass Fire Test Considerations Approved by an accepted testing institute Part of an approved Fire-Resistant rated framing assembly Must be glazed correctly

43 V. Applications of Fire-Resistant Glazing Improper Applications Examples of applications where improvements can be made can you spot what is wrong with this picture? X The banner and blinds would prevent the sprinkler system water from reaching the glass.

44 V. Applications of Fire-Resistant Glazing Improper Applications What s wrong with this picture? X effective Doors using a wire glass material Wire glass is not Human Impact Safety Rated, therefore it should not be used as large pieces in doors where people could come into contact. Notice anything else wrong? The door is also open, which inhibits the fire glass from being in the case of a fire.
