Building Collapse
Feb 04, 2011

Purpose:

To list  key points to keep in mind when responding to reports of building collapses, partial building collapses, roof and deck collapses, etc.

 

Signs of Potential Collapse

 

Bulging walls

Cracks in walls

Windows or doors not operational

Split beams, rafters, ridge pole

Bowed columns

Bent trusses

Sagging Q decking

Creaking noises

 

Remove occupants from the structure and notify the building department for further assistance. There would be no reason for fire department personnel to enter the structure. Secure utilities if it can be done safely.

 

Initial Response

 

2 Engines, 1 Truck, Rescue, Car, TAC

Note: Truck 2 will bring TAC; one Firefighter and Captain responding with Truck 2, two Firefighters responding with TAC (Truck 2 should respond with the TAC even if Truck 1 is the designated Truck on the assignment).

 

Collapse Occurred

 

Secure the scene

1.    Remove all would be rescuers from debris

2.    Notify all utility companies and begin remote shut off

a.    Gas/propane

b.    Water

c.    Electric

d.    Fuel oil

e.    Cable/phone

 

3.    Establish and communicate zones to all personnel

a.    Hot,  account for secondary collapse and hazardous atmospheres

b.    Warm, area for our equipment

c.    Cold, Incident command post

 

 Potential Victim Search/Rescue

  1. Hailing – Call out for anyone in the debris pile and listen for a response
  2. Caller – Did the caller use a cell phone? Call back with C2’s phone to locate
  3. Evaluate other information/signs. Vehicles, neighbors, etc.
  4. Look in void spaces DO NOT commit unless proper shoring is in place.

 

If there is no likelihood of trapped victims do not enter or operate on debris pile, notify the building department for assistance 

Notify the USAR Team if there is a known or high likelihood of a trapped victim. CT USAR contact information is in appendix.

 

Stabilizing the Building for Search/Rescue

1.    Paratech rescue struts should be put in place for temporary shoring. An estimated measurement should be taken to select the proper size strut combination. STRUT should be built outside of the collapse area.

a.    Cut two (2) 3’ long 4x6

b.    Center the paratech foot plate on the wood, the small holes should be in the center for nailing. Nail plates to the wood. These will become the header and sole plates

c.    Attach the plates to the strut, stand up the strut so the collar is closer to the ground and screws the piston down

d.    Place the top 4x6 (header) perpendicular to the roof/floor system that needs supporting

e.    Align the sole with the header.

f.     Make sure the strut is close to 90 degrees

g.    Spin the collar on the strut until it is snug

     

2.    Additional shoring should be at the direction of the building department representative working with the fire department incident commander.

Use of ANSI 207 Hi-Visibility Safety Vests
Sep 01, 2010
Purpose:

The Federal Department of Transportation (DOT) requires the use, with certain exceptions for firefighters, of high-visibility safety vests when firefighters are operating on “Federal Aid highways”.

 

This policy is designed to meet the intent of the 2007 edition of NFPA 1500 and the U.S. Department of Transportation, 23 CFR Part 634,and the “Manual of Uniform Traffic Control Devices” (MUTCD).

 

The following is the applicable section from CFR 23:

 

§ 634.3 Rule. All workers within the right-of-way of a Federal-aid highway who are exposed either to traffic (vehicles using the highway for purposes of travel) or to construction equipment within the work area shall wear high-visibility safety apparel. Firefighters or other emergency responders working within the right-of-way of a Federal-aid highway and engaged in emergency operations that directly expose them to flame, fire, heat, and/or hazardous materials may wear retro reflective turn-out gear that is specified and regulated by other organizations, such as the National Fire Protection Association. Firefighters or other emergency responders working within the right-of-way of a Federal-aid highway and engaged in any other types of operations shall wear high-visibility safety apparel.

 
Procedure:
  1. American National Standards Institute (ANSI) 207 compliant safety vests will be issued to all apparatus and shall be stored so they are readily accessible by personnel. Vests are large enough to fit over turnout gear.
 
  1. Responding Personnel shall wear vests at all incidents within the right of way of limited access highways: I-95, Route 7 Connector, Merritt Parkway.
 
  1. Vests shall be donned when directed to do so by the company officer, but at the latest upon exiting the apparatus.
 
  1. It is highly recommended that personnel also wear safety vests when operating at incidents on local roadways.
 
  1. Personnel shall be required to wear vests at any other time if directed to do so by the I.C.
 

Non Vest Incidents (Exceptions to the Rule)

Several incident types may be encountered where the donning of a safety vest may actually increase risk of injury for fire department personnel or where wearing of the vests may in fact be otherwise impractical. Under these limited situations, the requirement for donning ANSI-compliant vests by personnel directly involved in hazard area “Hot Zone” activities is modified.

 

The exceptions for wearing a safety vest applies only to members directly involved in activities within an established “Hot Zone” and only when the Hot Zone is protected from the hazards of moving traffic by apparatus blocking, lane closures, etc.

 

The required ANSI-compliant safety vest need not be worn when a member is required to:

 
  1. Don SCBA to work in close proximity to a source of heat such as during suppression of a vehicle fire.
 
  1. Don hazardous materials personal protective equipment to avoid potential exposure to chemicals or other contaminants
 
  1. Or when directly involved in a technical rescue incident such as extrication, high or low angle rope rescue, swift water rescue, etc. Appropriate PPE shall be worn.
 

All members on-scene performing duties or involved at activities other than those listed above are required to don ANSI compliant vests. I.C., pump operator, etc., would be typical of this type of activity.

 

When there is no longer a hazard from a fire, chemical or technical rescue activities, personnel involved in those activities are required to don a safety vest while on scene.

Last Chance Rescue Filters
Sep 01, 2010
Purpose:

 The “Last Chance Rescue Filter” device and carrying case has been issued to be attached to, and carried, as part of each SCBA. The Last Chance Filter is a onetime use device that is only to be utilized in an out of air emergency or SCBA malfunction. Under no circumstances may the filter be used to extend work time in an IDLH environment.  

 
Procedure:
A.     Training

Department members shall be trained according to the manufacturer’s specifications (care, inspection, use, mayday, and limitations) for the Last Chance Filter upon unit being issued, and then at least annually. Training shall consist of classroom as well as a practical evolution. Training units must not be used in an IDLH atmosphere. Training shall be documented in the firefighters training record. Initial training shall utilize the manufacturer’s program. Members shall also be trained in the Norwalk Fire Department Mayday procedure (SOP 2.082).

 

The department also has six (6) training units that allow for training in attachment and use of the device. Training units are red; the actual unit is blue. Training units must not be used in an IDLH atmosphere.

 
B.     Inspection 

Department members will inspect SCBA and filter packaging at the beginning of each shift and after each alarm where the filter may be exposed to the elements or other hazardous conditions.

 

Filters will be inspected monthly and documented in the department’s monthly SCBA logs.

 

In the event of damage to the foil package the company officer shall be notified and unit taken out of service with and forwarded to the Deputy Chief, who will in turn forward to the Assistant Chief.

If the firefighter has any doubt of the filter’s condition the unit shall be taken out of service.

If a filter is reported missing or opened, the company officer shall be notified. The company officer shall notify the Deputy Chief so that a replacement can be obtained and the matter referred for an investigation.

All documents shall be cc to the Assistant Fire Chief.

 

C.    Emergency Use

A Mayday should have already been initiated when a filter is placed in use and updated after filter is utilized. (In a case of catastrophic SCBA failure the filter may need to be utilized before the Mayday would be given).  

 

If unit is utilized in an emergency the company officer and the firefighter or firefighters shall notify the Deputy Chief for documentation, replacement and investigation. All documentation should be cc to the Assistant Chief.

 
 

Important Points to Remember

 
  • The filter is not a substitute for good air management practices.
 
  • The filter shall not to be used to extend your time in an IDLH atmosphere
 
  • As the name implies the filter is your “Last Chance” and should only be used as such in an emergency after you have initiated a mayday and initiated self rescue techniques.

Pre-connect Hose Stretch, Private Dwelling
Sep 01, 2010
 

NORWALK FIRE DEPARTMENT
STANDARD OPERATING PROCEDURE
 
SOP:       2.004.01
TYPE:     Operations                                                                                                            
TITLE:     Pre-connect Hose Stretch, Private Dwelling
DATE:     November 1, 2009  
   
 

 Purpose:
The purpose of this document is to establish a “Norwalk Fire Department standard method” of stretching a pre-connected hose line that all members of the department will use. Training will be conducted for all personnel to ensure the concepts are understood, and to reinforce the use of this method.
Procedure:
1.      Firefighter assignments:
    1. Nozzle man: TOP (2)loops (Approx. 60’).
b.      Hydrant man: Bottom (2)loops.
 
  1. Officer will make the determination as to what type of nozzle and length.
 
  1. The Nozzle man will be responsible for pulling the proper pre-connect from the proper side. (On apparatus with side discharges).
a.      AT NO TIME SHOULD THE HOSE BE BROUGHT OVER THE CROSSLAYS OR CAB OF THE ENGINE.
b.      If need be, it will be the responsibility of the Driver to disconnect the line and reconnect it on the proper side.
 
  1. While pulling the top (2) loops, the Nozzle man will grab the hose as it comes off the engine, flip it upside down, and proceed to walk approximately five (5) feet away the engine and STOP.
a.      The hose should be resting over the forearm.
b.      While waiting for the Hydrant man, the Nozzle man will grab the nozzle and hold it in the opposite hand of the hose.
 
  1. The Nozzle man will wait for the Hydrant man to grab the next set of loops.
 
  1. The Hydrant man will pull the bottom (2) loops, flip it upside down, and proceed to move away from the Engine.
a.      The Driver will be responsible for seeing that the remainder of hose is flaked out from the bed. 
b.      AT NO TIME SHOULD THE HOSE BE LEFT IN A PILE ALONGSIDE THE ENGINE.
 
 
7.      The Nozzle man will make his way to the front entrance of the fire building or designated area.
 
8.      The Hydrant man will attempt to follow the Nozzle man, staying several feet away. (This will allow the Hydrant man to flake the hose off his arm first)
 
9.      When the Nozzle man reaches the front door (designated area):
a.      Using the same side leg that is being used to carry the hose, the Nozzle man STEPS BACK on the hose that is trailing him. 
b.      While holding the nozzle in the opposite hand, the Nozzle man tosses the bundle of hose to the ground (several feet away). 
c.      The Nozzle man kneels on the hose that was being stepped on and kneels on the hose abutting the nozzle.
d.      This will prevent it from being pulled out from under them.
e.      At this point the Nozzle man should don his mask and other PPE.
f.        The Nozzle man should NOT take his weight off the hose until it is flaked out.
 
10. While the Nozzle man dons his mask, the Hydrant man quickly finishes  
 flaking out his hose.
     
11. When the Hydrant man has finished flaking out the hose, he will grab a
 fold from the middle of the hose the Nozzle man has tossed down (look
 for and try to grab a coupling if available [50’ lengths only]).
a.      The hydrant man will proceed in the opposite direction to the entrance (when possible), creating a loop in the hose and a straight path for the hose to advance (should be 25’- 30’ back from the entrance if possible).
        
12. It will be the responsibility of the Hydrant man to see that all hose is
       flaked out properly.
 
13. When enough line is properly in position, the Officer will call for water (NOTE: if the Officer is preoccupied by the occupants or is completing his 360° of the building, the nozzle man may call for water when ready).
a.      By opening the nozzle fully, the Nozzle man will bleed the line, dispelling any air and ensuring the proper psi.
b.      The Nozzle man and officer will enter on the same side of the line and proceed to the fire.
 
14.The Hydrant man will quickly take out any kinks that may have formed and finish donning his mask and PPE.
 
 
 
 
 
15.The Hydrant man will feed the hose into the building and around any corners.             
a.      When this has been achieved, he will meet up with the officer at the Nozzle to provide backup and relief.
 
16. The Nozzle man will have the option to:
                    a. Call for more line.
                    b. Open the nozzle in an emergency.  
                    c. Determine the rate of advance.
                    d. Determine when to sweep the floor with the nozzle.

Engine (when assigned)

Officer and Nozzle Position: locate the stuck elevator car and establish communications with the passenger/s, determine if it is incident or emergency, attempt to open elevator using Primary Removal procedures

 

Driver: at Engine, available to bring in additional equipment; i.e. Little Giant

 

Note: all personnel must be on channel 3 (talk-around) to ensure communications within the building. The truck driver will relay any information (under control, etc.) to dispatch via channel 1 (main)

 
Procedure:

1.    Locate the elevator

Using the lobby indicator
Communicating with the passenger/s through hoist way doors
Using the car floor indicator in the machine room
Using the car floor indicator in the machine room
Opening up the hoist-way and looking up the shaft and counting landings
Looking down the smoke hole and counting landings
Using emergency phones (if present and operable)
 

2.    Incident or Emergency?

Establish communications with trapped occupant/s to determine whether the situation is an Incident or an Emergency

 

Incident: a stuck elevator containing passenger/s not in immediate danger and having no medical issues

Emergency: a stuck elevator where a passenger is experiencing a medical emergency, severe panic, or fire is endangering passenger/s

 

Note: an incident can escalate to an emergency at any time. Elevator conditions must be monitored throughout the call by constant communications

 

3.    Elevator mechanic

Have the building manager ensure that an elevator mechanic has been contacted and will be responding to the building

City operated buildings may require dispatch to contact housing in order to summon an elevator mechanic

 

4.    Primary Removal Procedures

Check elevator contacts
Have passengers make sure that the emergency button has not been pressed
Have passengers try to push the “door open” button

Have passengers make sure that the elevator car doors are fully closed by pushing them

Check hoist way doors in the vicinity of the stuck car (Truck Can Firefighter will be doing this)

Activate Fire service Phase I
If the car does not respond, turn to “Bypass” then “off”

Attempt to reset the system by shutting down power to the stuck elevator, waiting 15 seconds and restoring power

If these steps fail, ensure that an elevator mechanic has been called with secondary procedure

 

5.    Secondary Removal Procedures (hydraulic elevators)

Have members in the machine room shut down power. Prior to beginning secondary procedure, personnel must ensure power is shut down to all cars being used

Explain to the passenger/s that the elevator is going to be lowered
Open the hoist way door at the lowest floor
Have personnel open the relief valve

Once the elevator is almost level with the floor radio personnel to close the relief valve

Open the elevator car doors

After power has been shut down to the stuck elevator, FD personnel shall not restore it

Ensure that out of service elevators and hoist way doors have been closed and secured prior to clearing the scene

 

6.    Secondary Removal Procedures (traction elevators with elevator keyholes)

Locate the best floor for passenger removal. Every attempt shall be made to remove passengers up and out of a car. If passengers must be removed down and out, a Little Giant ladder should be laid across the hoist way opening

Have personnel in the machine room shut down power to the stuck car

Choose the appropriate key and trip the interlock to open the hoist-way door

Open the elevator car door (it may be helpful to have the passengers assist in opening the elevator car door)

Once power has been shut down to the stuck elevator, FD personnel shall not restore power

Ensure that out of service elevators and hoist way doors have been closed and secure prior to clearing the scene

 

7.    Secondary Removal Procedures (Traction Elevators without elevator keyholes)

Locate the best floor for passenger removal. Every attempt shall be made to remove passengers up and out of a car. If passengers must be removed down and out, a Little Giant ladder should be laid across the hoist-way opening

Have personnel in machine room shut down power to the stuck car

Align the adjacent elevator as close to the stuck elevator as possible for poling

Have personnel in the machine room shut down power to the adjacent car
Pole the hoist-way door open

Open the elevator car door. (It may be helpful to have the passengers assist in opening the elevator car door)

Once power has been shut down to the stuck elevator, FD personnel shall not restore power

Ensure that out of service elevators and hoist-way doors have been closed and secured prior to clearing scene

 

8.    Emergency Removal Procedures

Note:

Only used after Primary and Secondary procedures have failed, AND the situation fits conditions for an emergency as defined in this SOP

 
  1. Forcible entry with hydra ram or air bag:
*Power should have already been shut down during secondary procedure
Use a halligan to gain a purchase on the hoist-way door

Insert the hydra ram or air bag as high as possible in the hoist-way door at the leading edge (the one ton 6” X 6” bag is to be used for this operation. Line up the center of the air bag with the edge of the door)

Open the hydra ram or inflate the air bag
Open the elevator car door

Ensure that out of service elevators and hoist-way doors have been closed and secured prior to clearing the scene

 
  1. Top hatch removal
*Power should have already been shut down during secondary procedure
Open the hoist way door above the stuck car

Ensure all personnel entering the shaft have been secured with life saving rope. Only two people may enter the shaft at one time

Open the top hatch
Lower a ladder into the elevator car
One firefighter must enter the car
Each passenger must be secured with life-safety rope prior to removal

Passengers are passed to firefighter on top of car where they are helped out of the shaft one at a time

Ensure that out of service elevators and hoist-way doors have been closed and secured prior to clearing the scene

 
 
 
Key points
  • Personnel must be sure their radios are set to channel 3 to ensure communication within the building. The truck driver will act as a relay to dispatch
  • An elevator mechanic must be called to the scene
  • Once FD shuts down the power, we do not turn it back on
  • Even though power is shut down to the car, there will still be power on top of the car
  • While poling, power must be shut down to both cars
  • Anybody operating in a hoist-way shall be tied off using the life safety rope
  • Primary and secondary procedures are not bypassed during emergency conditions due to the fact that it is usually faster to gain access using primary and secondary procedures
  • Prior to clearing scene, always make sure that all elevator and hoist-way doors have been secured in the closed position
