Study Notes

Water Tower Operations

Aerial ladders should only be extended as far as necessary for accurate water penetration to the target.
Extending the aerial to unnecessary heights is counterproductive.

Aerial Apparatus Equipment

TFS apparatus with waterway capabilities are equipped with both smooth bore and combination nozzles.
Straight streams are more effective for fire penetration and suppression, while fog streams are used for exposure protection and decon.

Bresnan Distributor and Hose Kit

The kit is designed to be used with an elevated waterway (apparatus with the “Elevated Water Supply” attribute).
It allows water to be applied to areas out of reach of hand lines or too dangerous for crews to operate hand lines from.

Aerial Operations Safety

The aerial device should be extended 1-2 meters above the edge of the roof during roof operations.
Aerial devices should not be left raised if not in use, and should be bedded when operations are completed.
The ladder should be positioned no greater than 70 degrees for safe climbing angles.

Creeper Controls and Ladder Placement

Creeper Controls can be enabled by the turntable operator and activated by a firefighter at the tip for final adjustments of the ladder placement.
Creeper Controls should only be enabled when the firefighter at the tip is appropriately secured with a safety belt attached to a rung and with footplates in use.

Climbing and Fall Prevention

Personnel shall climb the aerial ladder when it is in the desired position.
Firefighters shall not ride the ladder while it is being raised from the bed.
All rungs shall be aligned for safer ascent before climbing an aerial ladder.
Personnel operating from an aerial apparatus shall be secured by a TFS-approved Fall Prevention Device.

Safety Precautions

Apparatus ladders shall never be in contact with a structure.
Safety shall never be compromised by overloading a ladder device.
The operator at the turntable shall not reposition the aerial when any firefighter is on the ladder, unless the firefighter at the tip is incapacitated.

Limited Visibility Operations

When water tower operations are conducted in limited visibility, a ground spotter should be utilized when the water tower stream is being repositioned near the edges of the fire building.

Valve Under Monitor (VUM) Operations

Apparatus equipped with VUM enables the waterway to be used as an improvised standpipe.
The TFS Standpipe Kit gate and pressure gauge shall be used in line at a hose coupling before the nozzle.

Electrical Hazards

All wires shall be considered live.
Clearance of 3 meters (10 feet) for overhead wires and 1 meter (3.3 feet) for TTC streetcar power lines shall be maintained.
Caution must be taken to never provide a ground for an electrical circuit.

Learn about the proper use of aerial ladders and nozzles during Water Tower operations for effective fire suppression and penetration. Understand the differences between straight streams and fog streams.
