Alerting workers to the exposure

of toxic H2S gas

Personal, wearable instrument alerts workers to exposure of toxic H2S gas providing instantaneous alarms for life-critical safety scenarios

It Hydrogen Sulphide (H2S) is a fast-acting poison that can desensitize and render the body unconscious in no time. As the human senses are not reliable indicators, wearable gas sensors are necessary for early detection. ION Science’s new ARA H2S personal single gas monitor offers 24 months’ continuous operation and robust design for use in harsh environments. It enables workers in a wide range of industrial process applications to monitor their exposure to the toxic gas and provide an alert when safe levels are exceeded.

H2S is commonly found during the drilling and production of crude oil and natural gas plus in wastewater treatment and utility facilities and sewers.

The gas is produced as a result of the microbial breakdown of organic materials in the absence of oxygen and can also be found in textile manufacturing, food processing, hot asphalt paving and mining.

Colourless, flammable, poisonous and corrosive, H2S gas is noticeable by its rotten egg smell but continuous exposure to even low levels quickly deadens olfactory desensitisation. Although the scent of H2S is a characteristic, the smell is not a dependable indicator of the gas presence or for indicating increasing concentrations of it.

With toxicity similar to carbon monoxide which prevents cellular respiration, monitoring and early detection of H2S could mean the difference between life and death.

In a strategic move to further expand its portfolio of high-performance gas detection instrumentation, ION Science has launched a range of cost-effective, low maintenance, disposable ARA Single Gas Detectors for keeping workers safe from toxic industrial gases.

The personal, wearable instruments enable workers to monitor their exposure to toxic gases as well as oxygen enrichment and depletion, alerting them when safe levels are exceeded.

Ideal for petrochemical site plant workers and on-site contractors, the small, lightweight ARA single gas detector comprises six models including four gas types:

– Hydrogen Sulphide (H2S)
– Oxygen (O2)
– Carbon Monoxide (CO)
– Sulphur Dioxide (SO2)
