Why hydrogen sulphide is dangerous, and how to detect it

Hydrogen sulphide (H2S) is a colourless, flammable gas that’s infamous for its characteristic rotten egg odour. But its pungent smell is far from the worst thing about it – hydrogen sulphide is an incredibly hazardous substance. Many of the risks that hydrogen sulphide presents are difficult to monitor, so it’s vital to have some kind of detection system in place to pick up on any leaks. We can help you with that – with more than 25 years of experience behind us here at Gas Alarm Systems, we use our extensive in-house expertise to deliver reliable, cost-effective fixed gas detection systems tailored to meet the specific hazards of your industry. So, here’s our brief guide to the dangers of hydrogen sulphide.

Hydrogen sulphide is highly toxic

Hydrogen sulphide is highly toxic to humans, even at low concentrations. It affects the body by inhibiting the enzyme cytochrome c oxidase, which impairs cellular respiration (basically, it stops oxygen from getting to your cells!). Inhalation of even small amounts of hydrogen sulphide can lead to a range of health issues, including headaches, nausea, dizziness, and eye and respiratory tract irritation. Exposure to higher concentrations can cause more severe symptoms such as loss of consciousness, respiratory failure, and, in extreme cases, death.

Hydrogen sulphide is also highly flammable and explosive

As well as its toxicity, hydrogen sulphide is highly flammable. It forms explosive mixtures with air, which makes it very prone to combustion. Even at low concentrations, hydrogen sulphide can ignite easily and create a significant fire hazard. This characteristic, combined with its ability to travel over long distances, increases the potential for accidents and fire-related incidents in various industrial settings. So, it’s vital to have fire safety equipment on site when dealing with hydrogen sulphide so you can quickly put out should an ignition occur.

Common industries where hydrogen sulphide is present

Hydrogen sulphide is commonly used in industries such as petroleum refining, natural gas processing, wastewater treatment, and mining. Workers in these industries are at high risk of exposure to hydrogen sulphide due to its presence in natural gas deposits, crude oil, and various industrial processes. Without proper safety precautions, employees may suffer acute and chronic health effects, making it essential for employers to prioritise safety protocols and provide adequate personal protective equipment.

Hydrogen sulphide may be invisible to the naked eye, but its dangers are far from inconspicuous. The toxic, flammable, and environmentally harmful characteristics of this gas demand the utmost respect and attention. Understanding the risks associated with hydrogen sulphide and implementing appropriate safety measures means you can mitigate its dangers and ensure the well-being of both individuals and the planet. Our fixed gas detectors can help you with this.

How gas detectors protect you from hydrogen sulphide

Our fixed gas detectors are one of the safest ways to reduce the likelihood of exposure. Depending on the size of your premises, you can install one or multiple gas alarms in your workplace – we’d always advise placing them in key areas where the risk of leakage is at its highest, such as near containment tanks.

Our detectors are designed to pick up on trace amounts of fumes, so you can rely on them to alert your staff to the danger and give them plenty of time to evacuate the area until it can be made safe. You can buy our gas detectors as either fixed or portable devices, providing comprehensive protection from the risks posed by asphyxiate, toxic and flammable gases, by giving you early warning of a potential leak.

Our in-house experts take care to provide reliable, cost-effective solutions tailored to meet the specific hazards of your industry. Feel free to take a look at our range of fixed gas detection systems or portable gas detection monitors, including carbon monoxide systems and carbon dioxide systems, or if you have any questions or need any advice, by all means call us on 01423 862240, and we’ll be happy to answer any questions you may have.
