increasing comfort. Gear loops have been added for storing equipment, but their design allows easy removal
when using the harness for confined space entries. Quick-connect shoulder straps and leg loops make
donning the harness simple and fast. Molded pads on the leg loops can be adjusted to the most comfortable
position.
WATER TANK CONSTRUCTION
The tank shall have a rated capacity of 500 U.S. gallons, complete with lifetime warranty. Acceptable tank
manufacturers are UPF and ProPoly.
The tank shall be constructed of 1/2” thick Polyprene sheet stock. This material shall be non-corrosive stress
relieved thermoplastic, white in color and UV stabilized for maximum protection. The tank shall be of a
special configuration and is so designed to be completely independent of the body and compartments. All
exterior tank joints and seems shall be extrusion welded and/or contain the Bent Edge™ and tested for
maximum strength and integrity. The top of the tank is fitted with removable lifting eyes designed with a 3-
to-1 safety factor to facilitate easy removal.
The transverse and longitudinal swash partitions shall be manufactured of Polyprene material. All partitions
shall be equipped with vent and air holes to permit movement of air and water between compartments. The
partitions shall be designed to provide maximum water flow and meet NFPA rules. All swash partitions
interlock with one another and are welded to each other as well as to the walls and floor of the tank.
WATER TANK CAPACITY
The water tank shall be rectangular in shape and shall have a maximum capacity of 500 US gallons.
TANK LID & FILL TOWER
The tank shall have a combination vent and fill tower.
The tank cover shall be constructed of recessed 1/2” thick white Polyprene, stress relieved, UV stabilized
material. A minimum of two lifting dowels shall be drilled and tapped to accommodate the lifting eyes.
OVERFLOW AND VENT PIPE
The fill tower shall be fitted with an integral 4" ID, Schedule 40 PVC combination overflow/vent pipe
running from the fill tower through the tank to a 4" coupling flush mounted into the bottom of the tank to
allow water to overflow beneath the chassis.
TANK TO PUMP
The tank to pump piping shall be capable of delivering water to the pump at a rate of five hundred (500)
gallons per minute. This flow shall be sustained while pumping to a minimum of 80% of the certified tank
capacity with the apparatus on level ground. No exceptions are allowed to this section.
The tank to pump line shall run straight, without elbows, from the pump to the front face of the water tank
and down into the tank sump. A rubber coupling shall be included in this line to prevent damage from
vibration or chassis flexing. The tank to pump line shall be plumbed with 3" Schedule 40 stainless steel high
pressure pipe.
