Safe Egress
What is Common Path of Egress and why is it important?
It is the distance measured from the most remote point within a story to the point where occupants have access to two fire exits
What is a Fire Barrier?
It is used to separate interior stairways from other egress components, and can separate different occupancies or divide mixed occupancies into different compartments. Mainly used for interior walls and are thinner than fire walls.
Mention at least two methods of passive fire protection
What do exit signs do?
guides to the nearest exit in case of emergency
What are the six types of sprinkler systems? mention at least three
Wet pipe sprinkler, Dry Pipe, Wet pipe with antifreeze solution, Preaction Sprinkler ,Deluge Sprinkler , On-off system.
What are refuge areas?
They are fire-rated rooms that allow quick access to safety, especially for people in tall buildings, or people that are unable to scale flights of stairs.They are most used in hospitals and prisons.
Fire is a special kind of oxidation known as?
Combustion
What are the "needs of a fire"
Fuel, high temperature, and oxygen
What is one of the most dangerous materials to firefighters and is known as “solid gasoline”?
Untreated polyurethane
True or False:
Standpipe system is an external hydrant , typically for 75 ft buildings and located on each floor. It helps firefighters reach all locations in tall buildings.
False
How does Exit Access work?
At any point in the building and is unprotected, or only minimally protected from smoke and fire, this ends when the building occupant reaches the exit.
What is a Fire Wall?
A fire-rated wall whose purpose is to stop the spread of fire. It must extend from the floor to the roof, exterior wall to exterior wall, and be made of non-combustible material. It should also have a 3 hour fire rating.
Reasons why a fire is dangerous to people
What are the five ways smoke spreads throughout a building?
Natural Convection, stack effect, expansion of heat and air, wind effects, HVAC systems
Difference between Wet Pipe and dry pipe systems
For wet pipe sprinkler water is always in the pipe instead of dry piipe,sprinkler pipes are full of air instead of water
How can you control a fire by considering its needs? mention at least one
What are some common sources of ignition?
Chemical, Electrical and Mechanical
Design intents in building fire safety
What are the three methods of Smoke Control?
Confinement of Smoke, Dilution, and Smoke Exhaust Systems
True or False:
Some non water suppression are carbon dioxide, Hydrants Agents and Foams
False
Why is there a minimum required distance between exits?
There is a minimum distance required between exits in order for the egress pathways to be sufficiently remote from one another to minimize the possibility that they will become simultaneously unsafe or inaccessible in a building emergency.
Why are there different types of detectors required in buildings?
Because building and fire types vary, requiring different detection methods.
How do flame detectors identify fires with little smoke?
They detect infrared radiation emitted by flames.
How can fire alarms be activated?
By a detector or a person at a manual station.
What two indicators must be provided on fire alarms?
Audible (horn) and Visual (strobe light)
