WARNING
ICON 5, 66
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 serious injury or death to personnel and
damage to equipment.
