32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Fire safety objective
- A statement in OBC Part 1 describing the goal a building must achieve, such as limiting the probability of injury to occupants from fire.
- Functional statement
- A Part 1 statement describing what a building or component must do to meet an objective, such as limiting the spread of fire.
- Alternative solution
- A design that does not follow the acceptable solutions but demonstrates compliance with the objectives and functional statements, subject to authority approval.
- Group F1 occupancy
- High-hazard industrial occupancy involving flammable liquids, combustible dusts, or other processes that create a high fire or explosion risk.
- Building height
- The number of storeys between the lowest and highest floor levels in a building, used to determine construction and fire protection requirements.
- Major occupancy
- The principal use or occupancy of a building or part of it, classified under OBC Part 3 as Group A, B, C, D, E, F, or G.
- Fire-resistance rating
- The time in minutes or hours a building component resists fire exposure while maintaining its separating or structural function under standard test conditions.
- Fire separation
- A construction that resists the spread of fire, which may or may not have a fire-resistance rating depending on the requirement.
- Fire damper
- A device installed in a duct where it penetrates a fire separation to close automatically and prevent fire spread through the duct.
- Limiting distance
- The horizontal distance from an exposing building face to a property line, street centre line, or adjacent building face, used for spatial separation.
- Exposing building face
- The exterior wall of a building that could expose an adjacent building or property to fire, evaluated for fire-resistance rating and unprotected openings.
- Unprotected opening
- A window, door, or other opening in an exposing building face that lacks fire protection and is counted in the permitted opening area.
- Travel distance
- The distance measured along the path of egress from the most remote point in a floor area to the nearest exit.
- Occupant load
- The number of persons for which a floor area is designed, calculated by dividing floor area by the occupant load factor for the occupancy.
- Dead-end corridor
- A corridor segment with only one direction of egress, limited in length because occupants could be trapped if fire blocks the single path.
- Manual pull station
- A fire alarm initiating device located along the egress path and at exits so occupants can manually activate the alarm system.
- Fire alarm annunciator
- A panel that displays the location and status of alarm, supervisory, and trouble signals to assist responders and building staff.
- Smoke detector
- A device that senses smoke and initiates an alarm, required in corridors serving sleeping rooms and in certain residential suites.
- Standpipe system
- A fixed piping system with hose connections that provides water for firefighting, classified as Class I, II, or III by intended user.
- Sprinkler design density
- The minimum water application rate in millimetres per minute over the design area that a sprinkler system must deliver for a given hazard.
- Residential sprinkler system
- A sprinkler system designed primarily for life safety in residential occupancies, typically installed under NFPA 13R with limited height and area.
- Smoke control system
- An engineered system using pressurization, exhaust, or both to keep egress paths tenable and limit smoke spread during a fire.
- Fire command centre
- A room in a high-rise building containing fire alarm annunciation, smoke control controls, and communications equipment for fire department use.
- Smoke venting
- A provision that releases hot smoke and gases from a space, such as an atrium or industrial area, to improve tenability and firefighting conditions.
- Smoke alarm
- A self-contained device that detects smoke and sounds a local alarm, required in dwelling units on each storey and near sleeping areas.
- Egress window
- A window in a dwelling unit sized and located to allow occupants to escape or be rescued, with specified dimensions and sill height.
- Fire blocking
- Construction within concealed spaces in combustible assemblies that stops the movement of fire and hot gases through the cavity.
- Flammable liquid
- A liquid with a flash point below 37.8 degrees Celsius, classified by flash point and boiling point for storage and handling requirements.
- Combustible liquid
- A liquid with a flash point at or above 37.8 degrees Celsius, subject to storage and handling rules based on its classification.
- Explosion venting
- A designed relief area that opens to release pressure from a deflagration to a safe outdoor location, protecting the structure and occupants.
- Flash point
- The lowest temperature at which a liquid gives off enough vapour to form an ignitable mixture near its surface.
- Fire separation continuity
- The requirement that a fire separation extend continuously through concealed spaces and intersections so that fire cannot bypass it.
