Protection against Hydrogen Sulfide exposure: Single gas detection monitoring and ARA Dock4

16 June 2022

Despite advances in health and safety strategies and personal protective equipment (PPE), hydrogen sulfide was still responsible for 46 worker deaths between 2011 and 2017, according to the USA Bureau of Labour Statistics. Mitigating the risk of hydrogen sulfide exposure is something ION Science is keen to emphasise.

The ARA H2S Single Gas Detector is an essential piece of PPE from ION Science that can make a huge difference in protecting workers against hydrogen sulfide exposure.

At both low and high concentrations, hydrogen sulfide poses serious risks for health. High concentrations can cause ‘knockdown’, where workers are overcome and collapse due to exposure – this can lead to death in some cases. Low concentrations cause respiratory issues, eye irritation, and headaches. The impact of hydrogen sulfide is increased when areas are confined (such as wells, pits, pipes, tankers, tunnels, and service hatches). As a gas commonly present in industries such as oil and gas refining, mining, pulp and paper processing, and sewage and wastewater management, ensuring there is appropriate protection for workers from hydrogen sulfide should form part of a wider occupational safety approach that reduces exposure, risk, and injury.

The ARA H2S Single Gas Detector is a continuous monitoring device that operates for 24 or 36 months from activation (dependent on version). It is maintenance free, intrinsically safe, and offers three alarm notification in the event of H2S exposure exceeding limits: a flashing light, audible alarm, and vibration. These alarms are adjustable to high and low settings for user preferences. Calibration and bump test reminders also ensure that the user’s device is up to date and operating at appropriate levels of safety. Lightweight with a sturdy attachment for wearing within the breathing zone, the ARA H2S Single Gas Detector is designed for workers’ convenience and protection against the risks of hydrogen sulfide exposure.

To accompany the ARA gas detector range, ION Science offers the ARA Dock4 bump test and calibration station. This can simultaneously test up to four ARA gas detectors at once, saving on testing time and gas usage. The ARA Dock4 is ideal for larger plants and operations and the need to keep devices up to date with calibration and testing. It has a rechargeable internal battery that offers up to five hours of operation when fully charged. The ARA Dock4 is certified electrically safe to UL 61010-1.

With greater monitoring and protection against hydrogen sulfide exposure risks, it is possible to reduce the number of work-related incidents and improve overall worker safety. Using cost effective and worker-specific devices like the ARA H2S Single Gas Detector is an easy way for businesses to add another layer to the occupational health and safety strategy. Combining this with the ARA Dock4 means all devices can be always kept in peak condition for testing and monitoring.

ION Science continues to support the improvement of worker health and safety through monitoring devices, testing stations, PPE and expert insight for gas detection and instruments.
