When hazmat personnel arrived on the scene of an ammonia leak at a cold storage facility one night, they were ready for anything. One responder wore a G7 personal multi-gas detector and the team also had a G7 EXO area monitor at the ready.
They immediately set up the G7 EXO downwind of the facility to determine the hazard level outside. At 21:08, the device detected high levels of ammonia (NH3), alerting the team of a potentially volatile situation. A high-alarm notification was sent to the fire chief, who was off duty many miles away.
The danger escalated as high-gas alarms for both ammonia and hydrogen sulfide (H2S) started coming in. The chief was able to monitor the situation remotely from his smartphone. With instant access to real-time data from the scene, he could follow and manage the response as it unfolded.
By 21:42, after 18 high-gas exposures were reported, the call was resolved and firefighters were off to their next emergency – a structure fire.
