NFPA 1410 Evolution 2: Reverse Lay from Engine
training scenario created by
This evolution is a reverse lay using two engines. The first engine (base pumper) will be positioned at the fire scene, the second engine will then perform a reverse lay from the base pumper to the hydrant. The companies will then deploy an attack line and a backup line. The company is permitted to use tank water to supply the attack line, but must have an established hydrant supply prior to charging the backup line.
All lines shall be completely deployed from their hosebeds
All nozzles should be flowing the minimal accepted preasures
Timing starts when given a signal by the training officer, and ends when the required 300 GPM flow is being delivered.
The maximum allowable time for this evolution is 4 minutes.
Start by staging fire engines away from the hydrant and the fire scene.
2. First Engine to Fire Area
The first engine should proceed to the fire scene. Time starts when the engine stops at the scene. The driver of the fire engine should place the engine into pump, and two fire fighters should advance an attack line 150'.
3. Second Engine to Fire Scene
After a 30 second delay the second engine should proceed to the fire scene. All firefighters except the driver should exit the apparatus. One firefighter should grab supply lines off the second engine, and snub the tires of the first engine, then signal for the second engine to proceed to the hydrant.
4. Secure Water Source and Flow Water
The second engine should proceed to the water supply, secure it and pump back to the first engine. The other firefighters who exited the second engine should advance the backup line. The evolution is complete when both lines are flowing at the required rate and pressure.
