exterior crew responsibilities include what

horizontal/vertical ventilation placement of portable ladders

What three things should a aerial operator consider when on an incident of a known fire
34

Is this a defensive fire in which master stream preparation is a priority

are crews searching directly over a fire and require ladder placement to the windows

is there a victim on the balcony

What must be evaluated before overhaul begins

Condition instability of the structure

if Assessment of structural stability determines high risk involved in manual overhaul what should be considered

Hydraulic and mechanical overall

sprinkler activation may create——-regardless of the size of the fire resulting in obscured vision and toxic gases 39

cold smoke

define conventional wood roof dimenensions | 42

2 x 6 or larger

define lightweight roof construction | 42

Trusses the driving strength from compression intention consisting of triangles arranged in a single plan that load applied at the points of intersection of the members Common material 2 x 3 or 2 x 4 should one fail likely entire truss will fail as well as each trust system after that

members should not be on the roof of a structure where fire is suspected or confirmed in the truss area without being —— 43

Independently supporting

what three factors determine the amount of time a roof can be considered structurally strong 43

What is the type of construction and its condition has the fire entered or taken possession of the cock loft attic area how long the fire has been burning and it’s extend

traditional lumber joists failed in about —— minutes | 44

engineered floor joists failed in about —— minutes | 44

Just a note if they use a picture of an A frame Gable style roof, the difference between type three and type five dimensional lumber is type five will have a mouth cut and wall stud

Multiple section laminated arches roofing system is subject to failure ——- than the one piece laminated arch 48

Faster

what is the tool of choice for metal roof decking | 49

Rotary disc saws

concrete has satisfactory compression strength but minimal —- strength 50

tensile

of all concrete roofing systems which has the greatest resistance to fire 51

Flat concrete roof precast & poured in place, with concrete columns

define heavy timber roof | 53

2 to 3 inch thick wooden planks or the proof seal supporting good timbers minimum dimension 8 inches may withstand several hours of fire exposure

define gable roof | 55

A frame with a Ridge pole and rafters extends down to a beam that rest on the outside wall rafters a 2 x 6 16 to 24 on center

define barn roof | 57

A.k.a. Gambrell

define hip roof | 57

All walls are loadbearing conventional ordinary construction consist of ridgepole and hip rafters

define bridge truss roof | 58

commercial warehouses may be heavy grade construction 2 x 12 lumber with wooden top and bottom

Truss arch roof | 59

Collapse potential great

define bowstring truss roof | 60

Different from truss arch, uses metal tie rods and turnbuckles to provide lateral support Very dangerous on the fire conditions expose the cable holding all in place supporting roof may fail violent collapse

define flat roof | 63

rafters 2 x 6 covered with one by six sheathing plywood generally uses lightweight I beams or web trusses

name two types of roofing material for flat roofs | 64

corrugated metal covered by alternating layers of tar Corrugated metal decking with lightweight concrete top layer

define inverted roof | 64

Insulation is above waterproofing membrane keeps ultraviolet Sunray ozone damage to minimum how was in place by layer of rocks inherently spongy

define rain roof | 65

Essentially a second roof are the flat or gabled of lightweight construction built over original roof add a dead load difficult dancing Heights fire

Define façade | 66

Architectural projection providing weather protection occupancy identity decoration supported by unit to which is attached conceals equipment and machinery

Define extensive roof system green building | 68

Soil less than 6 inches vegetation low growing plants such as grass and Maas minimal care and maintenance

define intensive roof system green building | 68

8 inches or more of growth soil regular care and maintenance needed

define simple intensive roof system green building | 68

Combination of both extensive roof system and intensive roof system

Define thermal system solar panel

Convert sunlight to heat presents less danger to fire operations because they do not create electricity however they generate heat using water and other fluids considered passive

Define photovoltaic systems

generate electricity I’ll let you components and associated circuitry may cause shock storage battery may leak during fires creating potential hazmat
