What is Firestop?   Firestop systems, if installed correctly, will help restore the

rating of a floor or wall as it is penetrated by an object or joint and resist the spread of smoke and fire.

  It is part of the life safety plan in structures. Also included are air ducts with dampers, smoke and fire alarms, wired glass, fire rated doors, and sprinkler systems among other things.

Why is it necessary?

  How do people react during a fire?

  To give people more time to safely exit a structure, even if they don’t react right away.

  Mandated by the Codes

•  IBC, NFPA, NEC, FBC


The Firestopping Problem

Objective: Understand the magnitude of the fire problem


•  I PASSED INSPECTION •  AHCA SAYS IT’S OKAY

•  I’M CERTIFIED •  RED IS RIGHT

•  AHCA INSPECTION SHOW A LOT OF RED.

Code Requirements Objective: Understand the key requirements related to firestopping in applicable codes


8.3.5.1* Firestop Systems and Devices Required. Penetrations for cables, cable trays, conduits, pipes, tubes, combustion vents and exhaust vents, wires, and similar items to accommodate electrical, mechanical, plumbing, and communications systems that pass through a wall, floor, or floor/ceiling assembly constructed as a fire barrier shall be protected by a firestop system or device.

The firestop system or device shall be tested in accordance with ASTM-E 814...

Life Safety Code (NFPA 101-2009)

• Through penetrations shall be protected by an approved through-penetration firestop system installed and tested in accordance with ASTM E 814 or UL 1479, with a minimum positive pressure differential of 0.01 inch (2.49 Pa) of water. The system shall have an F rating and a T rating of not less than 1 hour but not less than the required rating of the floor penetrated.

• Exception: Floor penetrations contained and located within the cavity of a wall do not require a T Rating.

712.4.1.2 Through-penetration firestop system.


Through Penetration Firestop Systems tested to ASTM E 814 / UL 1479 F-Rating

The duration of time in which flames do not pass through the system.

T-Rating

The time period that the penetration firestop system, including the penetrating item, limits the maximum temperature rise to 325°F (163°C) above its initial temperature through the penetration on the non-fire side when tested in accordance with ASTM E 814.

Not a pass/fail criterion To receive either rating the firestop must pass the hose stream test


WL5223a.pdf WL5096f.pdf


Typical Application

Block Wall F-Rating = 2 Hrs Steel Pipe 2” Annular Space Min: Point of contact (top) Max: 2.0” (below the pipe)


UL 1479: Optional water leakage rating

W-Rating (optional)

  Determines effectiveness of a firestop system to restrict flow of water.

  Tested to resist up to 3 feet of water column for 72 hours.

  Fully fire-tested after water exposure - must perform as well as non water-tested assembly


Membrane Penetrations 712.3.2 …recessed fixtures shall be installed such that the required fire resistance will not be reduced. Exceptions:

1. Steel electrical boxes that do not exceed 16 square inches in area provided that the total area of such openings does not exceed 100 square inches for any 100 sq ft of wall area. Outlet boxes on opposite sides of the wall shall be separated as follows:

–  1.1 By a horizontal distance of not less than 24 inches

–  1.2 (fill the wall with cellulose or mineral fiber insulation)

–  1.3 By solid fireblocking in accordance with 717.2.1

–  1.4 By protecting both outlet boxes by listed putty pads

–  1.5 By other listed materials or methods


Putty Pads

Index


713.2 Installation. Fire-resistant joint systems shall be securely installed in or on the joint for its entire length so as not to dislodge, loosen or otherwise impair its ability to accommodate expected building movements and to resist the passage of fire and hot gases.

(NFPA 101 (2009) 8.3.6.5* Joints made within or between fire resistance–rated assemblies shall be protected

with a joint system that is designed and tested to prevent the spread of fire for a time period equal to that of the assembly in which the joint is located. Such materials, systems, or devices shall be tested as part of the assembly in accordance with the requirements of ASTM E 1966, Standard Test Method for Fire-Resistive Joint Systems, or ANSI/UL2079, Standard for Tests for Fire Resistance of Building Joint Systems.

713.3 Fire test criteria. Fire-resistant joint systems shall be tested in accordance with the requirements of either ASTM E 1966 or UL 2079. Nonsymmetrical wall joint systems shall be tested with both faces exposed to the furnace, and the assigned fire-resistance rating shall be the shortest duration obtained from the two tests.

713.1 General. Joints installed in or between fire-resistance-rated walls, floor or floor/ceiling assemblies and roofs or roof/ceiling assemblies shall be protected by an approved fire-resistant joint system designed to resist the passage of fire for a time period not less than the required fire-resistance rating of the wall, floor or roof in or between which it is installed.


ASTM E 1966 joint cycling test

Almost all construction joints will be dynamic

Non-compliant joint seal Code-compliant joint system


Code requires Complete inspection + 100% compliance

Section 109.3.6 – Fire-resistant penetrations

“Protection of joints and penetrations in fire-resistance-rated assemblies shall not be concealed from view until inspected and approved.”

Section 109.6 – Approval required

“…Any portions that do not comply shall be corrected and such portion shall not be covered or concealed until authorized by the building official.”


HWD0209f.pdf HWD0342f.pdf


Code Requirements Key Points to Remember

  Firestopping is required by the Building Codes, Fire Codes, Life Safety Code and Electrical Code

  All fire rated assemblies require joints and penetrations shall be installed with a tested and approved systems

  Wall Penetrations do not require T- Ratings

  Floor penetrations contained and located within the cavity of a wall do not require a T- Rating.

  The Building Code also mandates proper documentation and complete inspection



Objectives: Understand when and why Engineering Judgments are typically used

Apply published industry guidelines to evaluate the technical merit of Engineering Judgments

Know the code articles that relate to the use of engineering judgments


• 104.11 Alternative materials, design and methods of construction and equipment. The provisions of this code are not intended to prevent the installation of any material or to prohibit any design or method of construction not specifically prescribed by this code, provided that any such alternative has been approved. An alternative material, design or method of construction shall be approved where the building official finds that the proposed design is satisfactory and complies with the intent of the provisions of this code, and that the material, method or work offered is, for the purpose intended, at least the equivalent of that prescribed in this code in quality, strength, effectiveness, fire resistance, durability and safety. When alternate life safety systems are designed, the SFPE Engineering Guide to Performance-Based Fire Protection Analysis and Design of Buildings, or other methods approved by the building official may be used. The building official shall require that sufficient evidence or proof be submitted to substantiate any claim made regarding the alternative.

• 104.11.1 Research reports. Supporting data, where necessary to assist in the approval of materials or assemblies not specifically provided for in this code, shall consist of valid research reports from approved sources.

• 104.11.2 Tests. Whenever there is insufficient evidence of compliance with the provisions of this code, or evidence that a material or method does not conform to the requirements of this code, or in order to substantiate claims for alternative materials or methods, the building official shall have the authority to require tests as evidence of compliance to be made at no expense to the jurisdiction. Test methods shall be as specified in this code or by other recognized test standards. In the absence of recognized and accepted test methods, the building official shall approve the testing procedures. Tests shall be performed by an approved agency. Reports of such tests shall be retained by the building official for the period required for retention of public records.


When/why is an EJ used? When no tested system exists that exactly matches the conditions of the field application Typical situations:

  Annular space larger/smaller than tested   Irregular hole shape   Hole shape different than tested   Curtain wall construction not identical to that tested   More penetrating items in hole than system allows   Access to one side only   Oversized or exotic insulation types   Structural member penetrations   Intersections of rated assembly with non-rated assembly (e.g. roof deck)


Who should issue Engineering Judgments?

  IFC Guidelines call for one of the following:

•  Firestop Manufacturer’s qualified technical personnel

•  FPE or other PE, in concert with manufacturer

•  Third-party accredited testing and listing lab

  Could better be named one of the following:

•  Technical judgment

•  Extension of data

•  Technical evaluation

•  Equivalent Fire Resistance Rated Assembly (EFRRA)

• Firestop Custom Detail

  Called “Engineering Judgment” as IFC historical artifact
