The Evrsafe Integrated Safety System is a proactive toxic gas detection system.

The ISS1040 sensors are installed in various areas of the boat, including the helm, engine room, galley and bedrooms. All sensors are connected back to the central processing unit (CPU), which incorporates a LCD display showing readouts from individual sensors. The processor is comparatively sophisticated in relation to other systems on the market, in that it is able to detect and measure a variety of toxic gases, including CO, nitrogen dioxide (generated by diesel engines), hydro carbons, LPG, butane and smoke.

Once a toxic gas has been detected, the ISS1040 CPU will alert the crew and passengers, via audio and visual displays, where the gas has been detected before it can reach dangerous levels.. The type of gas detected is also displayed on the LCD display, with the levels in parts per million, it also indicates whether the levels are increasing or decreasing. The EVRsafe ISS1040 CPU can audibly warn the crew with spoken commands, instructing them to open specific hatches or vents to remove or disperse harmful gases. If contamination increases to dangerous levels, the CPU is also able to switch external equipment, such as generators, fans and pumps, on or off to bring air quality back to acceptable levels.
