WARNING
ICON 66, 42
Open and close all valves slowly during any procedure. Sudden changes in
pressure may cause equipment to react faster than personnel can be alerted.
Ensure surrounding personnel are aware of changes being made to settings on
equipment. Failure to comply may result in injury or death to personnel and
damage to equipment.
Pump and roll procedures must be performed from vehicle cab. Do not use pump
operator's panel for pump and roll procedures. Failure to comply may result in

motion. Failure to comply may result in damage to equipment or injury or death to
personnel.
