School Bus Lift

I ran across the picture above in my Facebook find and thought that this picture is worth a thousand words.  If you take a look at the roof of the school bus, the instructors painted 5 steps for the students to follow.  The picture was posted on the City of Turlock – Fire Department Facebook page from some training the had on their new Paratech rescue equipment.

Here are the steps:

  1. Identify the load (Type C or D School 30,000 Lbs)
  2. Stabilize the top vehicle
  3. Lower the bottom vehicle (Remove the air for the tires and/or capture the suspension)
  4. Lift the top vehicle
  5. Separate the vehicles/extricate/patient removal

So what do school buses weigh?

School Bus Type Gross Vehicle Weight Rating*
Type A1 GVWR of less than 10,000 lbs.
Type A2 GVWR of more than 10,000 lbs. A popular style Type A introduced in 2004 was rated at 14,000 lbs. GVWR.
Type B GVWR of more than 10,000 lbs.
Type C GVWR of more than 10,000 lbs. Type C school buses typically range between 23,500 lbs. to 29,500 lbs GVWR, depending on seating capacity.
Type D GVWR of more than 10,000 lbs. Type D school buses typically range between 25,000 lbs. to 36,000 lbs. GVWR, depending on seating capacity.

* Gross vehicle weight rating ( GVWR ) is the estimated total weight of a school bus that is loaded to capacity, including the weight of the vehicle itself plus fuel, passengers, and other miscellaneous items such as extra aftermarket parts.

Heavy Rescue

18-wheeler falls off overpass crushes car below

Often many extrication instructors setup some outside of the normal training scenarios where the students usually comment “that would never happen”.  One of those happened in Texas. A tractor and trailer fell off overpass in Sugar Land, Texas and crushed the car below. The driver of the car was able to climb out of her vehicle with a little help from some bystanders.

Outside the Box

Often many extrication instructors setup some outside of the normal training scenarios where the students usually comment “that would never happen”.  One of those happened in Texas. A tractor and trailer fell off overpass in Sugar Land, Texas and crushed the car below. The driver of the car was able to climb out of her vehicle with a little help from some bystanders.

From a training perspective, what would be your plan if the vehicle had occupants trapped? Do you know what heavy wrecker resources are available in your response area? Do you have the equipment to stabilize, lift, and/or remove the vehicle from under the trailer?  Take some time to run a scenario thru your mind about what you would do.

School Bus Auxiliary Heaters

Rescuers often remove the side windows of a school bus and cut from the bottom of the window to the bus floor.  Rescuers need to locate any coolant lines prior to cutting to ensure the lines are not cut and leak heat coolant.

School Bus Auxiliary Heaters

In the past, school district bus yards had to plug in the engine block heater on school buses to warm it enough to start a cold diesel on a winter morning.  However, this didn’t heat up the passenger area of the bus.  So school districts started installing auxiliary heaters which operate as hot water furnaces utilizing the buses own diesel fuel and batteries to produce heat. The heaters circulates engine coolant to transfer heat to the engine and heat exchangers.  Often, these heaters are timer controlled and start 1-2 hours prior to engine start-up.

The heater becomes part of the school bus heating system, supplying added heat for passengers while reducing fuel costs and emissions from unnecessary engine idling. An integrated pump circulates heated coolant to warm the engine block, making starting easier while reducing start-up engine wear.

 

The lines that carry the coolant thru the heat exchangers and the engine typically run along the floor of the bus.  Rescuers often remove the side windows of a school bus and cut from the bottom of the window to the bus floor.  Rescuers need to locate any coolant lines prior to cutting to ensure the lines are not cut and leak heat coolant.
