PD's/Chapter 1- Introduction/Description Flashcards
Due to the size of these structures, what may become a major problem..?
CROWDING of the stairs/ stairs must be kept clear
PD’s?
- originally built for 2 family occupancy
- 1 to 3 stories in heigh
- attached, semi, detached
- split level-may have as many as 5 levels
- generally rectangular
- 20x40
- class 4 - exterior wood / brick veneer / stucco / asbestos shingle / aluminum siding
- class 3 with brick exterior walls
Major Weakness from a Firefighting and fire protection standpoint?
OPEN/UNENCLOSED STAIRWAY
What is commonly found in Newer constructed PD’s?
LIGHT WEIGHT MATERIALS
How many entrances are common?
2 entrances
- main entrance usually in front
- secondary entrances located side/and or rear or front
In structures more than one story, the interior stairs to the cellar will usually be located under the main stair
A dwelling which has 2 or 3 stories in front may be 3 or 4 stories in the rear…?
TOP FLOOR may be used as a point of reference
Straight Line Colonial..
BALLOON FRAM CONSTRUCTION commonly found
-Due to the limited ventilation of the attic/3rd floor, conditions in this area will be extremely punishing
-THE ROOF OF THE FRONT PORCH allows for easy access to upper floor bedrooms
Cape Style Houses…
A frame cape-entrance and side entrance with stoop
Wide line cape-rear entrance and may have 2 window dormers that are normally found facing the street…presence of dormers indicates 2nd floor bedrooms, easiest access to these bedrooms is exposure 2 and 4
Queen Anne…?
BALLOON CONSTRUCTION MOST COMMON-poor workmanship, open holes for service lines
LARGE OPEN STAIRS
vertical arteries-hot air ducts, dumbwaiter shafts, boxed in space around fire places and pipe recess, FAST UPWARD FIRE TRAVEL
-Fire escape attached to COMBUSTIBLE WALL
-roofs- peaks, dormers, overhanging eaves and possibly cupola
Cupola?
tower like room with a round or dome shaped roof
Flat Roof PD’s?
MAY have decorative peak- ABSENCE of a window in this peak may be and indication of a flat roof
-many attached dwellings were built with firewalls that cannot be relied on..exposures must be monitored
May have scuttle/skylight
Ranch…
Asymmetrical, single story structures with simple floor plans
-kitchen, living room and bedrooms are located on the first floor
Utilities in basement /cellar
-also possible to find living quarters in cellar
Split level..?
Sidesplit- split level configuration where the multiple levels are visible from the front elevation…typically garage is on the side of the house and there is a floor above the garage housing the bedrooms
-each floor is separated by half flight of stairs
Semi Attached..?
side by side units sharing a COMMON WALL
-each house’s layout is a mirror image of its twin
Special considerations?
- cellar areas used as living quarters-NO SECONDARY MEANS OF EGRESS
- cellar with unfinished ceilings..open joist
- lack of secondary means of egress from upper floors
- CONTROL AND MANAGEMENT OF INTERIOR STAIRS IS CRITICAL TO OPERATION
- attic stairs to attic or 3rd floor may be behind a small door resembling a closet
Pull Down ATTIC STAIRS…?
SHOULD NOT BE USED FOR ATTIC ACCESS OR LINE ADVANCEMENT..these are lightweight stairs….PORTABLE LADDER SHOULD BE USED
OFFSET WINDOWS at the top and /or bottom of the second floor staircase should…?
NOT BE USED FOR VEIS
Fire involving the electrical service…?
may energize the aluminum siding …ground is completed when an aluminum ladder is placed against, or a firefighter makes contact with the siding
Victims can be easily overlooked in trees/brushes…
thoroughly examine areas under windows (especially when found in the open position..victims may have jumped prior to arrival of units
