    Default On scene size-up

    I volunteer for a small department that has trouble with a standard
    on scene size-up.(We get alot of errs? and umms?) Does anyone have a cheat sheat they would be willing to share?? Something like
    1. Initial size-up
    2. Take command
    3. On scene assessment
    4. Additonal Resourses?
    what else would make this list more complete??

    I recommend just using the same format every time. It will soon become second nature.

    For example:

    Engine 2 on scene.
    Two story, frame, single family, fire showing on 2nd floor.
    Attacking with 2 1-3/4 lines.
    Main St. command.


    Engine 9 on scene.
    Two vehicle accident, one vehicle on its side.
    I-10 command.


    Truck 1 on scene.
    Nothing showing.
    Elm St. command.

    Simple, concise, and covers the basic scene assessment. Subsequent, pertinent, updated information is transmitted as it is obtained.

    Like fireman4949 said. How ever you do it stick to the same thing. With a volunteer crew sometimes it hard to have all the people you want. Train on it handle it the same every time. There are some many things that need to be done. Hope this doesnít get to length in what you wanted. This is only my opinion and may not be 100% of what everyone does.

    1. Take command first. Everyone needs to know who is in charge. We have a few officers that will turn over a jaws call to a couple of guys that have gone through different trainings.

    2. Initial scene size up should happen as soon as you pull up. As your coming in you need to look and see what other hazards there are before you exit the truck. Make sure where power lines are, on coming traffic, is there anyone with any kind of a weapon. Or in two words scene safe. Now more than ever make sure what kind of vehicle you are working with. Hybridís are ever where now it seems. Look for info on how to deal with them. See what you will need to stabilize the vehicle.

    3. On scene size up. Once you know it is safe to get out of the truck. The O.I.C. should see what he needs on scene. This is where it is going to get busy for the O.I.C.. If it looks like it is going to be extended extraction call for back up. Donít let pride get in the way. Long extractions ware people out quick. The on scene size up will be changing all the time. As the call progress different things will come up. Work with the EMS to see what they will need to have done.

    Every call is different. What you have to come up with will be different every time. Additional resources can come into it at any point. When you first pull up you may see you need power company, phone, or gas company. Let the EMS tell you if the want a helicopter or not. If EMS wont be on scene for what ever reason call it in. I know some rural places may have a 20 minute wait or better for an ambulance. Donít know if any of what I said will help you or not hope so. We like to use one towing company. One they are quick. Two very skillful. A lot of call they have been very helpful in. We know them they know us. Faces never change. We are always getting someone who knows how to use their rigs. Good luck. Learn as much as you can. Donít be afraid to ask questions.
    Training does not make perfect. Training makes permanent!

    I hope this is not too long, This is from my vehicle fire class but works for any fire.

    A Good Size-up
    Is A Four Part Process.

    1. Dispatch Size-up
    2. Approaching Size-up
    3. Arrival Size-up
    4. On scene Size-up
    Dispatch size-up begins, when you roll out of the door.
     Always repeat the address back to dispatch.
     Ask for additional information. Is this vehicle on the road, in a driveway or in a garage ?
     Is this a vehicle fire or a fire resulting from a collision ?
     Know your area, if this is on the highway, is it a high traffic area ?
    Why ask for additional information?
     If this vehicle is on the highway, we need PD in route NOW, for traffic control.
     If it is in a driveway or garage we need engine companies in route NOW, for possible structure fire.
     If it is a result of a collision, we need ALS in route NOW, for possible injuries.
    Remember !
    We can always disregard incoming help.
     A lot of people do not realize that some departments, especially volunteer, may have a ten to twenty minute response time, and miles of area to cover.
     If we wait until we arrive on scene to call for help, that help has the same or more response time.
     We must have Good Dispatch Size-up skills
    Approaching Size-up
    (Down the road)
     Do I see any exposures in immediate danger
     What is the wind direction?
     Topography; Is the vehicle on a hill?
     Dangers to crew, Is there oncoming traffic?
     What are the on lookers doing? (That is odd)
    Away Down The Road We Can Start To Refine Our Dispatch Size-up.
     What does this area look like? Is there woods or high grass on the side of the road? ( Exposures we did not know about ?)
     What is the wind direction? ( I need my apparatus up wind from the fire.)
     Topography, ( Is the vehicle on a hill ?)
     Dangers to crew, Is there oncoming traffic?
     What are the on lookers doing? ( Rescue ? )
    Arrival Size-up:
    (Still in the truck)
     Do I see open flames ?
     Is the vehicle occupied ?
     Is this a late model vehicle, or an older one ?
     What category is this fire ( front, rear, compartment ?)
     Do I need more help ?
    The Arrival Size-up Redefines The Approaching Size-up
     How much fire is there ? ( Do I need An Extinguisher or an inch and three quarter line ? )
     Is the vehicle occupied ?
     Is this a late model vehicle, or an older one? ( I have a late model Honda Civic )
     What category is this fire ( Front, Rear, Compartment ? )
     Do I need more help?
    On Scene Size-up
     Closer check for occupants ( Or escaped occupants injured ) ?
     Closer check of exposures
     Closer check of vehicle
    On Scene Size-up Redefines Your Arrival Size-up.
     Closer check for occupants
     Closer check of exposures
     Closer check of vehicle ( I have a late model Honda Civic Hybrid, 300-500 Volts )
     Do I need more help ?
    Remember !
    Good Size-up
    Is A
    Practiced Skill
    Not A Spur Of The Moment Decision

    Your Size-up Must Be A Continuing Process
