Types of construction
Is the most fire-resistive category of building construction. It is used for buildings designed for large numbers of people.
Type 1 construction (fire-resistive)
how could a balloon frame house be dangerous to fire men
its long, open stud channels act as natural chimneys, allowing fire to spread rapidly and vertically from the basement to the attic, often in minutes
what is the weakness of a steel
expanding and structural collapse
There could be fire resistance ratings of 2 hours There could be none.
Type 3 ordinary
some ordinary building are four stories but some can be up to_____
6-7
Is also referred to as noncombustible construction. All of the structural components in a _______ building must be made out of non combustible materials.
Type 2 construction Noncumbustible
how would a platform frame house be dangerous to fire men
due to the use of lightweight, engineered wood and large, concealed voids, which lead to rapid fire spread and unpredictable, sudden structural collapse
what is a strength of steel
steel has to be at temperatures between 1370°C and 1540°C (2500°F and 2800°F)
Thick wood wall and sutpports made of wood heavy wood and will with stand fire far longer than ordinary.
how quick should you be out of the fire station
within a minute to 30 seconds
what classification would heavy timber be put in
Type 4 construction
how could steel and copper be dangerous to firemen
In a house fire, iron and steel can pose several dangers to firefighters, including structural collapse, steam explosions, chemical exposure from metal fumes and galvanized coatings, and difficulty with standard firefighting techniques.
weakness of wood materials in type 3 houses
they are easier to ignite and have a weaker structure
Often collapse and do terrible in fires.
Type 5
what type of extinguisher should most people have in their house.
ABC
how quick will the fire reach the attic of a balloon frame
In a matter of minutes
how is gypsum dangerous to fire men
Gypsum presents two primary dangers to firefighters during a structural fire: the release of toxic and flammable hydrogen sulfide gas and the risk of a ceiling or structural collapse.
strength in wood materials of type 4 houses
the material is stronger than type 3 and is way more difficult to ignite and can withstand more fire much longer before the building collapses
What type should theoretically not catch fire.
Type 2
what type of extinguisher is obsolete and in the room
Soda acid
how long will the frame of a balloon frame house have before the chimney effect of a fire burns it down
10 to 30 minutes
how could wired glass be dangerous to fire men
Wire glass is dangerous to firefighters because it breaks more easily than standard glass and can create razor-sharp shards that trap a person's limbs. While the wire mesh is designed to hold the glass in place during a fire, it can turn a broken window into a jagged, trapping hazard for anyone trying to force entry or exit.
WHat are the strengths of masonry
They do not burn or detiorate
Can contain fires for a specified periond of time
Type1
Fire trucks upon special orders can hav______
