H2S alarm
An H2S alarm is a crucial safety feature in environments where H2S is present. This is a highly toxic, colourless gas with a strong odour of rotten eggs, commonly found in oil and gas refineries, wastewater treatment plants and industrial manufacturing. Even at low concentrations, H2S exposure can cause dizziness, nausea and respiratory irritation, while higher levels can lead to unconsciousness or fatalities. At WatchGas, we offer high-quality H2S alarms to ensure worker safety and regulatory compliance in hazardous environments.
