CFI rim seal fire protection for floating roof tanks

Stored product vapour will collect in the rim between the floating roof and the tank shell. This can mix with air when the rim seal is damaged, providing a hazardous mixture. Lightning or sparks produced by static electricity can cause a fire to occur. Hidden by the tank shell it may develop undetected until it reaches a dangerous intensity, possibly out of control.
