Mobile Flame Ionization Survey

Vehicle mounted flame ionization equipment is used to sample the atmosphere at ground level using sample tubes mounted at the front of the survey vehicle. This insures prompt, efficient, street leak detection.

The vehicle is driven very slowly as close as possible to the gas main. Leaks indicated by the flame ionization unit [FIU] are then verified and classified by making combustible gas indicator tests.

Areas surveyed are indicated on maps given to the operator prior to the survey. As each section of the map is surveyed, the operator will mark the map showing the area surveyed, the date and his initials.

Completed maps are returned to the gas company.

Walking Flame Ionization Survey

Service lines are checked by a consultant using a portable FIU. The atmosphere above the gas service line is sampled by a hand-held wand. This survey provides the most complete inspection.

Front yards, sidewalks, valve boxes and meters are checked thoroughly. Leaks indicated by the FIU are then verified and classified by making combustible gas indicator tests. Where vegetation damage indicates possible gas leakage, tests are conducted.

Winter Safety Patrol

We provide daily and nightly monitoring of critical cast iron pipelines during cold winter months.
