Which Hazards Do Gas Detectors Protect Against?

Gas detectors are a critically important piece of safety equipment. There are many different types of gases that are harmful to human life, and having an alert system is our first line of defence against these hazards.

There are two major types of gas detectors – single and multiple. Like their names suggest, single gas detectors excel at identifying solely the substance they are calibrated for while multi-gas detectors can cover a wide variety of situational requirements.

Depending on your individual needs, you may be fine with a single style device, but it is usually helpful to cover all your bases and consider a product that can look out for more than one.

A Detector for Every Gas Hazard

Aside from simple gas detection and identification, here are some other hazards that gas detectors can protect against:

  • Confined Space Hazards

Confined spaces create a special sort of hazard, as the presence of workers and substances within the same space can cause the risk of injury to increase significantly.

There is a variety of common gases that will need to be considered when workers are placed in a confined area, which is why a gas detector is such an important addition to any set of safety practices. Potential issues that can occur within a confined space include toxic and flammable gases.

  • Toxic Gases

Toxic gases are awful in that they can directly harm the health of an individual by creating a metabolic reaction in their body or by damaging their tissue. Exposure to these substances can cause both long-term and instantaneous effects that are problematic to your health.

These substances are typically found at significantly smaller concentrations compared to flammable gases, as the parts per million concentration simply don’t need to be as high to do as much damage. Due to the smaller parts per million concentration, these substances require a much more complex method of measuring and monitoring.

Gas detectors for this category will take measurements gradually over time to record the maintained level of exposure in order to calculate the Time Weighted Average, or TWA. Taking into account both short-term and long-term exposure, the device will keep an accurate recording for each individual person and allow for easy reading to ensure effective safety protocols for all workers.

  • Flammable Gases

Gas detectors are also used to protect people from harmful flammable gases. These substances create an explosion risk, encompassing a variety of gases such as propane, hydrogen, methane, and pentane, although many more also exist in this category.

Detectors create a safety net for users by keeping track of the surrounding area’s Lower Explosive Limit, or LEL range. This is basically the smallest amount of flammable gas that would be needed to ignite. LEL alarms tend to be set around 10% or 20% as this will give the user plenty of advanced notice of a rising level of dangerous substance so that they can get out of harm’s way.

If you are monitoring this risk in an area with several different potentially flammable substances, it is highly recommended to get a detector designed to detect multiple risks. Single detectors are calibrated for only a single gas and may leave you defenceless against a different type that it doesn’t know to look out for.
