Wireless Gas Detectors Bring Connectivity to Confined Space Entries
Wireless gas detectors are changing the way we work in confined spaces.
The way that we test the atmosphere within a confined space is changing. Although continuous monitoring of the atmosphere within a confined space has always been considered a best practice, many companies have traditionally found it difficult or impractical to implement. The attendant assigned to the entry can monitor the atmosphere inside the space with a portable gas monitor, but this is often cumbersome and requires additional equipment (a sampling pump and a piece of tubing or a probe). However, this setup only tests the atmosphere in one small area. Continuously monitoring the atmosphere throughout the entire space or in the area where the work is being performed is much more challenging. This is all changing thanks to wireless connectivity.
Wireless mesh technology embedded within some connected gas monitors enables the instruments to communicate with each other at a peer-to-peer level. Entrants inside the space carrying a gas detector enabled with peer-to-peer connectivity will share their readings with a connected area monitor or personal gas detector stationed with the gas tester or attendant outside the space, allowing them to “see” the readings and monitor the atmosphere through each of the entrants’ instruments.
Seeing the gas readings within a confined space is not just convenient: it saves lives. You’ve probably heard confined space horror stories like this a million times: the person inside of a confined space becomes unresponsive. The attendant responsible for monitoring the work goes into the confined space to check on his partner and is overcome by the same deadly gas. It’s a tragic story of trying to help a co-worker based on gut reaction rather than proper safety protocols. According to OSHA, these would-be rescuers make up 60 percent of confined space fatalities.
But with shared data on gas hazards, the attendant watching the hole in this example would have known what caused his partner to become unresponsive without being exposed firsthand. He could then take appropriate steps to rescue his peer, without putting himself in danger.
