The problem
Some temperature sensitive triggers were not x-rayed. These triggers could contain internal voids that would make the triggers susceptible to advanced creep causing false activation and venting of the cng.
The risk
VENTING OF THE CNG COULD RESULT IN A FIRE.
The fix
Thomas built will replace the type iii pressure relief valve with the newer design "generation 2.5" Pressure relief device.
