The simplest way to prioritize safety — BW Icon is a fixed-life, two-year, four-gas detector for the gas hazards that workers face most often. That means you can turn it on and activate two years of protection, with no need for sensor or battery replacement — and no hidden costs.  BW Icon is named for its display of simple icons for gas levels and device status. That means no live gas readings for workers to interpret and no time-consuming training. Instead, when there’s a gas alarm, the bell icon on the display will illuminate, along with an indicator next to the sensor in alarm, so workers can quickly clear the area.
