How to Select the Best Confined Space Gas Detector?

Updated: Oct 18, 2021

Best Confined Space Gas Detector

In a confined space, it may only take a few seconds for someone to succumb to the dangers of the environment. As a result, investing in high-quality gas detectors is one of the most important things you can do to keep your workers safe. However, selecting the most appropriate monitor for a limited location is not a simple task; it depends on the kind of work being performed and the type of space accessible.

In such a scenario, it is not possible to recommend a single type of gas detector for every situation. You must carefully evaluate the needs of your workers and choose the most appropriate detector for a certain location inside your facility.

The post is designed to help you with general-purpose considerations without considering the demographic, social, legal, or industry-driven regulations. So, you should look for experienced safety equipment suppliers in Dubai to buy the right gas detector depending on your specific requirements. Feel free to contact the professionals for a quick overview and other detail – after all, safety cannot be compromised.

What is a confined space?

While an enclosed area may be referred to as a ‘limited space,' this does not always imply that the space is confined in any other way. Confined spaces are places that have been fully walled off from the outside world and where there is a risk of exposure to poisonous odors, low oxygen levels, or explosive gases, among other things.

Workers on the building site are often needed to enter these locations to carry out their responsibilities properly. Routine inspections and scheduled maintenance may be performed in several locations, including chambers, pipelines, silos, tanks, and vats, among others.

Hazards of confined spaces

  • In the event that a person is wounded or killed as the consequence of a fire or explosion

  • Increased body temperature leads a person to lose consciousness while doing work-related tasks.

  • The condition in which a person is knocked unconscious or asphyxiated while at work due to exposure to hazardous gases or a lack of oxygen.

  • Drowning of any person asphyxiation by free-flowing solids of a worker throughout the course of their employment

Considerations for Buying the Best Gas Detector for Confined Spaces

Manufacturing companies that specialize in gas detection equipment put a high emphasis on their limited-space products. There are many versions available, each with its own set of features, pricing, and capabilities.

Although the perfect product for your project or workplace may be out there. It is critical to understand which features are essential for the way you want to utilize it before deciding on a specific gas detector.

Let’s consider the things that are important while selecting a gas detector for congested places:

Selection of sensors

Before you can select a detector, you must first determine what you want to measure. When operating in a restricted location, the sensors that your detector employs should accurately reflect the known and possible airborne hazards that are present.

Every space gas detector must contain at the very least Hydrogen Sulphide (H2S), LEL, carbon monoxide, and Oxygen sensors, as well as other sensors as required by the mission.

In confined regions where a particular gas is dominant, the use of substance-specific sensors may be required. Various gases may be utilized in conjunction with Ammonia, Sulfur dioxide, Phosphine, Chlorine, and Nitrogen Dioxide.

Many substance-specific sensors will be the safest approach in tight spaces where contaminants may vary significantly. It is possible to use chemisorption sensors that respond to a wide range of pollutants.

Operational flexibility

A device will be overlooked unless it is simple enough to be used by a worker daily. Gas detectors that are simple and straightforward are needed. When working in tight spaces, workers must be able to use the equipment without having to fiddle with configurations or try to sort out how to use advanced functionality on the device.

System of danger alarm

Gas detector warnings must be loud and highly visible to draw the user's attention in confined spaces that are likely to be both dark and noisy. Alerts such as flashing lights, buzzers, and explanatory messages should be kept an eye out for.

Working technology

Technology plays an important role in safety equipment, especially gas detectors. Generally, infrared sensors are a popular option for usage in small areas. These devices have a gas cell that transmits infrared radiation, enabling them to test an atmosphere from a distance. Because infrared sensors are unable to detect hydrogen, a catalytic sensor may be required in certain situations.

Intrinsic protection

The bulk of gadgets are classified based on their intrinsic safety. To put it simply, this means that they will not be able to ignite themselves. Class, I certification is required for some limited places.

However, certain restricted regions also need equipment to be certified for operation in Class II locations. Combustible dust is classified as Class II groups, and they may be needed in grain silos, among other places, for safety reasons.

If you aren't sure what hazards your workers are exposed to; it's time to do a hazard assessment of your workplace for better selection. For this, you can consult with safety equipment suppliers in Dubai to suggest a gas detector based on your unique work and on-site scenario, potential hazards, and other elements.

Budget constraints

Although price is important, it should not be the only consideration when deciding whether to purchase a certain item. The real-world cost of an instrument does not just comprise the cost of the instrument upfront; it also includes the cost of continuous maintenance and repair. The cost of the first purchase is just one factor to consider.

Remember to consider the cost of replacement parts including sensors, and power supplies, besides the instrument's standard warranty coverage. Don’t forget to make sure that the manufacturer's willingness to stand behind the product in the event of a problem.

Be Vigilant While Buying Gas Detectors for Confined Places!

Working in an enclosed location that includes hydrogen gas exposes you to the hazards of confined spaces and exposure to dangerous gases. When dangerous gases such as hydrogen gas are present in the workplace, using a gas detection system may prevent workers from being exposed to them.

Remember! If you haven't been in an accident, don't assume it won't happen to you. Safety provides access to first assistance for those who haven’t met accidents. Always take adequate safety measures before allowing people to work in confined places.
