This wall must extend beyond walls and roofs to prevent radiant heat of flames from igniting adjacent surfaces
What is a fire wall?
100
Flat, pitched and curved
What are types of roof designs?
100
Run, rise, stringer, handrail, baluster, nosing, newel post
What are stair components?
100
Rotate around a vertical axis by means of hinges secured to side jambs of doorway framing Single or double acting Generally required as exit doors in means of egress
What are swinging doors?
100
Contributes to combustibility Contributes to fire extension by flame spread Affects rate of fire growth to flashover Adds intensity to a fire because it contributes fuel Produces smoke and toxic gases that can contribute to life hazard
What is Interior Finish?
200
A wall that lies on a lot line between two buildings and is common to both buildings.
What is a party wall?
200
Asphalt shingles; Clay, slate, and cement tiles; Metal roof coverings;
What are roof coverings.
200
Enclosed with fire-rated construction depending on building height Generally serve two or more stories and part of the required means of egress Stair enclosures
What are protected stairs?
200
Protect openings in fire-rated walls Effective at limiting spread of fire and total fire damage Differences from ordinary doors
What is a fire door?
200
Steiner Tunnel Test; Produces a numerical evaluation of flammability of interior materials;Spread classification of materials
What is a flame spread rating?
300
The word used to describe a building when the floor area of a building is subdivided with fire-resistive partitions/walls.
What is compartmentalized.
300
Fundamental part of all buildings Primary function — Provide protection from weather Can contribute to fire hazard of a building
What is a roof?
300
Open metal stairs and landings attached to outside of a building Not permitted in new construction May not be able to support required live load created during emergency evacuations or fire suppression operations
What are fire escapes?
300

Hourly fire-protection rating Alphabetical letter designation Combination of hour and letter May be found on existing fire doors, but no longer used Inconsistencies

What are Methods for Classifying Fire Doors

300
Provided in buildings to maintain a comfortable environment for occupants; Regulate intake of outdoor air and recirculation of indoor air; Have potential to significantly affect any fire event Codes require: Smoke damper,Fire damper, Internal duct smoke detection device
What is an HVAC system?
400
Interior walls used to subdivide a floor or area of a building. These do not qualify as fire walls but may be used to achieve the goal of compartmentation.
What are fire barriers and/or partitions?
400
Highly combustible roof coverings.
What is wood roof shingles ?and shakes?
400
Required by building codes under certain circumstances; Stair enclosures using either active or passive smoke control; Mechanical ventilation system
What are Smokeproof Stair Enclosures?
400
Constructed with three or four sections or wings that rotate in a circular frame Designed to minimize flow of air through a door opening to reduce building heating or cooling losses Restrictions Must employ collapsing mechanism
What is a revolving door?
400
Can reduce flame-spread rating of some interior finishes Several types are available: Intumescent paints Mastics, Gas-forming paints, Cementitous and mineral-fiber coatings
What are fire retardant coatings?
500
This wall is not load bearing. It is used to separate the interior environment from exterior.
What is a curtain wall?
500
Framed structural units made of a group of triangles in one plane, Vulnerable to early failure under fire conditions due to reduced mass of components and interdependence of those components.
What is a truss?
500
Not protected from fire and smoke in building they serve Not enclosed with fire-rated construction. Allowed in buildings when connecting only two adjacent floors above basement level.
What are Unprotected Stairs?
500

Permit ventilation while door is closed Must close in event of fire to protect opening Closing usually accomplished by means of a fusible link Only fire doors listed for installation of louvers can have them installed

What are Louvers?

500
Vertical pathways in a building that contain building services, including: Plumbing, Electrical raceways,Telecommunications Data cables, Ductwork for ?HVAC and grease
What is a utility chase?
