Case Study

When an industrial office building in suburban Chicago complained about eye burning, fatigue and cold symptoms, EGSL was called in to determine the source. The building’s heating, ventilation and air conditioning (HVAC) system was quickly ruled out. As a result of interviewing employees and investigating their symptoms, EGSL suspected a natural gas leak — one that had not been detected by the facility’s gas sensors. EGSL sampled the air for volatile organic compounds and identified a low concentration of methane gas.
