What is a Class F fire?
Class F fires are fires which involve cooking oil or fat.
Whereas flammable liquids, such as petrol, usually have low flash and auto ignition temperatures, cooking oil or fats require temperatures in excess of 340°C to ignite..
What is a fire separation distance?
67. The “fire separation distance” is defined in Section 202 as the distance measured from the building face to the closest interior lot line, to the centerline of a street, alley or public way, or to an assumed imaginary line between two buildings on the same lot.
How thick does a firewall have to be?
2-inchNormally a 2-inch thick firewall is assembled at least 3/4 of an inch away from the wood-stud or steel-stud framing. This allows space for fire-blocking product to be installed between the floor levels.
What is the difference between a firewall and a fire separation?
So what is the difference between firewalls and fire barriers? Basically, firewalls are thick exterior walls with a higher fire-resistance rating, while fire barriers are interior walls with a lower fire-resistance rating.
What is a fire rated barrier?
The term “fire barrier” refers to a structure that has, at minimum, a one-hour fire resistance rating. Based on the occupancy type for that particular building, the rating can extend to a four-hour rating. By comparison, a “fire partition” must have at least a 30-minute rating for certain types of occupancies.
What type of fire do you use a fire blanket for?
Class A & B firesFire blankets are used to extinguish fires in the kitchen (cooking oil, fat pans, waste bins etc) and clothing fires. Covering with a fire blanket cuts the supply of oxygen to the contents of a pan or a person’s clothing. Fire Blankets can be used on Class A & B fires and works by smothering the fire.
What are the 3 types of firewalls?
Three basic types of firewalls —packet filtering, application, and packet inspection—are designed to control traffic flows. The previous descriptions provide general functionality of the operation of these types of firewalls.
Do fire doors divide the building into fire resistant areas?
Compartmentation is achieved by dividing the premises into ‘fire compartments’ through the use of fire doors, floors and walls of fire-resisting construction, cavity barriers within roof voids and fire stopping to services that penetrate through these dividing elements.
What are the 5 types of building construction?
Buildings can be categorized into five different types of construction: fire-resistive, non-combustible, ordinary, heavy timber, and wood-framed.
What are fire partitions?
Fire partitions are wall assemblies that enclose an exit access corridor or that separate tenant spaces in covered malls, dwelling units and guestrooms. Openings in fire partitions must be properly protected, but the amount of openings in a fire partition is not limited.
How many classes of fire are there?
four classesThere are four classes of fires: Class A: Ordinary solid combustibles such as paper, wood, cloth and some plastics.
What is a 2 hour fire rated wall?
Gypsum Board: Two (2) hour rated walls have two (2) layers of 5/8″ Type ‘X’ gypsum wallboard panels on each side of the steel studs. The “Fire Tape” product would be used as an alternative to conventional joint tape in specific systems when: 3.
What is building fire compartmentation?
Fire compartmentation is a strategy required to prevent the spread of fire and smoke, subdividing buildings into manageable areas of risk, whilst providing adequate means of fire escape routes and appropriately maintained facilities for fire prevention.
What is Type 3 Construction?
Building constructed of non-combustible materials but these materials have no fire resistance. TYPE III-A–Protected Combustible (Also known as “ordinary” construction with brick or block walls and a. wooden roof or floor assembly which is 1 hour fire protected).
What is Type 4 construction?
Type IV construction (Heavy Timber, HT) is that type of construction in which the exterior walls are of noncombustible materials and the interior building elements are of solid or laminated wood without concealed spaces.
What is the first step to take in conducting a fire risk assessment?
Identify the fire hazards. Identify people at risk. Evaluate, remove or reduce the risks. Record your findings, prepare an emergency plan and provide training.
What makes a firewall in a building?
A firewall is an assembly of materials used to separate transformers, structures, or large buildings to prevent the spread of fire by constructing a wall which extends from the foundation through the roof with a prescribed fire resistance duration and independent structural stability.
What is a Type 2 building?
Type 2: Non-Combustible Type 2 construction is typically found in new buildings and remodels of commercial structures. The walls and roofs are constructed of non-combustible materials. Specifically, walls are usually reinforced masonry or tilt slab, while roofs have metal structural members and decking.
How do you make a 2 hour fire rated wall?
Double the number of Type X sheets on the wall for a simple system installed over fire-resistant fiberglass insulation; each sheet of 5/8-inch Type X drywall is rated to resist fire for one hour, so two layers will produce a two-hour firewall.
What is a fire compartmentation survey?
Compartmentation is the process of sub-dividing buildings to help prevent the rapid spread of smoke and fire. Detailed compartmentation surveys are assessments of how well a dwelling can protect important escape routes and high-value areas, through sampling and locating potential fire dampers.
What is a compartment floor?
A compartment floor is horizontal component that forms part of the enclosure of a fire compartment. Compartment floors are required to provide a minimum degree of fire resistance as set out in Appendix A of Approved document B2 and Appendix A of Approved document B1 (for dwellinghouses).
