i.
Volatile Fuels and Hazardous Materials. Volatile fuels and hazardous or combustible
materials create a fire and explosion hazard. These hazards are always present but are most
prevalent during hot weather conditions. When storing hazardous or combustible materials or
volatile fuels under ULCANS, steps will be taken to ensure adequate ventilation of the camouflaged
area. In the event of fire, combustion by-products of the ULCANS can be toxic. Self-contained
breathing apparatus is required when fighting an ULCANS fire.
When using an ULCANS multi-screen configuration (of 8 ft high or
more), camouflage screens can be blown down when winds exceed
46 miles per hour. Damage to equipment may result. When winds
in excess of 46 miles per hour are expected, screens shall be
lowered and secured.
When heavy snow, sleet, or freezing rain is expected or occurring,
screens shall be lowered and secured.
j.
Deployment Checks. After screens are erected, they should be checked on a daily
basis for proper deployment and tightened as required. The screens should be checked more
frequently during strong winds, heavy snowfalls, sleet or freezing rain. Do not allow any great
accumulation of snow or ice to form on screens. Snow or ice must be removed from the screens
as soon as screens start to sag and begin to show signs of stress or strain due to the excessive
weight.
k. ULCANS Entry/Egress Doorway. An entry/egress doorway for the ULCANS can be
created as required using a Becket seam. For personnel to enter or leave the deployed ULCANS,
tie off a Becket seam approximately four feet from the ground and position stakes so that the
Becket seam will remain closed. Personnel may loosen a stake strap and fold the seam back to
enter or exit. Make sure to replace the material and stake strap after use. If a Becket seam is
placed in front of a concealed vehicle, the vehicle can exit quickly using the following steps:
(1) Untie the Becket seam enough to let the vehicle pass through (See Figure 2-3).
(2) Fold back the camouflage screen to avoid snagging on the vehicle.
(3) Reposition the poles and shape disrupters as necessary to create a doorway. For
large vehicles, place two poles of three pole segments each with shape disrupters
(dependent upon camouflaged items/vehicle) at or near doorway entrance/exit. If
necessary, personnel may raise and hold the poles to provide the necessary
clearance for the vehicle to enter or exit.
