Cumulative Exposure to Toxic Gases

As Health and Safety legislation tightens up world-wide, David Riddle, Business Development Manager at Crowcon Detection Instruments discusses the requirements of personal gas detectors in monitoring cumulative toxic gas exposure. Toxic gases have an effect on the human body and brain cumulatively. It is possible that, after hourly, daily or weekly exposure to relatively low levels of gas, illness or injury may become apparent. It is vital, therefore to understand time based exposure of workers to toxic gases and not just rely on instantaneous alarms.
