Wearable Devices Used for Long Term Exposure Monitoring

There are two leading methods of monitoring personal toxic gas exposure for industrial workers. The most accurate way is to provide workers with a personal toxic gas monitor, which monitors the air directly in the worker's vicinity at all times. An alternative approach is to provide workers with location tracking devices and mount fixed toxic gas monitors within the working environment where the threats are expected to occur, then combine the two data sources and monitor personal limits remotely using software.

Due to power requirements and technology constraints, most personal gas monitors on the market are relatively bulky and will not always be carried by all personnel that may be exposed to threats. However, personal toxic gas monitors come with the benefit of being more accurate and can alert the worker immediately when they have reached a limit. Alternatively fixed or wall-mounted sensors in combination with wearable location tracking devices are far more prevalent, affordable, and lightweight, but will require third-party software to combine the air-quality measurements with worker locations.
