4

Ventilation in Commercial building

____ may be required
____ may be necessary
Fans can be used w/ horizontal vent but remember:
If you open skylights or vents, make sure:

a trench cut
May intensify or spread fire
It is as close to the body of fire as possible

5

Extinguishment in Commercial if fire already so large handlines are ineffective:

Make use of any:
Hand lines of _______ inches or more are needed
Do not attack the fire with:
Larger hose=

Heavy elevated streams, ground monitors, large handlines, deck guns
Built in fire protection systems
2 1/2
Less than the volume required
Less friction loss, more water at point of attack

6

When fire spreads from floor to floor as a result of fire coming out of a window and into the one above. Also may be called _____

Auto extension or autoexposure

7

Commercial Buildings
_____ and _____ is common in people today
They may not leave when alarm sounds.
Exposure protection should be ____ and ____
Exposure method on closely exposed buildings:
Hoseliness should be placed to support:
Large open areas make confinement tough heat and smoke and fire can spread by _____

Complacency and disregard
Internal and external (large structures)
Flow water using large hose lines or master streams on the exposed buildings
Firewalls
Convection
* Autoextension is possible by extension of fire through windows

8

Search and rescue in Commercial buildings:
People tend to leave:
Check rear exits because:
Evacuation should begin:
______ may be a option depending on:

The way they came in
They can be blocked by storage (look for victims)
Firebuilding , 2 adjacent buildings, work outward
Shelter in place
Depending on severity of the incident and number of evacuees

9

Commercial Buildings
High ceilings make it hard to assess true heat intensity ______ can occur with very little warning

Many occupants also build ______ for storage

Flashover

a second floor
* collapse hazard
* Life hazard is typically reduced in the overnight hrs. however some stay running 24/7, also ,some apps on the floor above

10

Comm BLDG
Accountability must be established:
Preferably a RIC should be assigned:
Storage often blocks:
It is essential to have a :
FF's working without hoselines should use:

At every entrance and exit point
at every entrance
Means of egress in the rear of the strucuture
well thought out evac plan
a guide rope

11

Comm Building

It is best to begin preplanning when:

The building is under construction

12

Commercial occupancies can be broken down into 3 catgories

Mercantile - Retail business, supermarkets, dept store, drug store

Business - Courthouses, barbershops, doc office, they provide a service to the public

Industrial properties - Factory or a manufacturing location

13

ONCE ______ is accomplished in a MFD _____ operations can begin

confinement

Extinguishment

14

Both ______ and _____ are indicated for garden apt's

Horizontal and vertical ventilation

15

Garden Apt

typically have balconies with large glass openings. Fire can ____
Balconies can store:
Usually TL's can't be used because

Extend rapidly through these opening to the upper floors and the cockloft

Hazardous materials

They can't reach the building

16

Generally constructed of wood
built during baby boomer generation
can be covered by siding or brick veneer
2 to 4 stories high
up to several hundred ft in length
present large fire loads
placement of entrances causes access problems

Garden apartments
(because they are surrounded by landscaping instead of concrete)

17

Brownstone MFD's
Brickwalls separate each building including:
When a pocket door is closed
if the fire is located on the first floor
the first line should be pulled to:

the cockloft area

it creates void for vertical extension

the second floor to protect the stairs from fire spread or a second line can be stretched to the first floor entrance to extinguish the fire. The latter method is preferred.
Pg 264

18

Brownstone MFD's

Built with a high stoop that leads:
Under the high stoop is the ______ entrance
Below that is the ________

Second floor parlor * main floor

first floor or basement

Cellar

19

Construction
Built using non fire resistive materials
exterior is made of stone masonry, which is how it got its name
3 to 5 stories high
used to be occupied by a rich family
now every invidual room is rented out and tenants share kitchen and bathrooms
Can take up entire block

Brown stone
Multiple family dwellings

20

Row Frame MFD's
In a rapidly spreading cockloft fire:
Top floor fires are very dangerous
______ is critical
_____ is often necessary

Crews may have to operate a few buildings down to get ahead of the fire

Roof ventialtion

Trench cut

21

Row Frame MFD

Because of maneuverability _____ or ____ inch hoselines are recommended

Should also stretch lines to :

Any line stretched must be:

1 1/2 or 1 3/4

Long enough to cover the entire structure, front to rear

22

One of the greatest threats to FF safety in row frame MFD is :

23

General concern with row frame MFD's:

Timing is _______
