Why do I need a portable gas detector?

Why do I need a portable gas detector?

Gas detection equipment saves lives – FACT. But how do you know if you need a gas detector and if you do, what type of gas detection equipment is right for your business?

Gas detection equipment comes in 2 formats, fixed and portable, with many businesses using a combination of both depending on the factors they need to consider when assessing gas risks and how to keep their workforce safe. Portable gas detection is primarily used when you are a mobile worker who has to enter or work within an environment that is not monitored by fixed gas detection equipment and there is a risk of toxic, combustible/flammable gases or asphyxiation. Portable equipment is also a cost-effective solution for small businesses or for monitoring areas that are not commonly used making the installation of fixed detection equipment cost prohibitive.

Where is it used?

Most commonly, portable gas detection equipment is used for entering confined spaces, emergency services entering a potentially volatile area, tracing of gas leaks or when hot works are being carried out in hazardous areas. The most important job your gas detector does is to continuously monitor the air in your breathing zone to ensure that you are alerted to any potential risks which is why it is essential that your monitor sits on your body within approximately 10 inches of your nose and mouth. Wearing your portable equipment on your belt may not detect any potentially lethal gases being inhaled and overexposure or asphyxiation can occur.

What Sensors do I need?

Once you’ve decided that portable gas detection is right for you, you need to work out what sensors you require. A risk assessment of the working environment must be carried out to identify potential gas hazards and then the appropriate sensors can be selected. Most commonly, the atmospheric dangers in industry include flammable gases such as methane / natural gas, oxygen (either deficiency or enrichment), Carbon Monoxide and Hydrogen Sulphide. In addition to this, there are toxic gases that are specific to certain industries such as chlorine and ammonia that require close monitoring. With a variety of gas detection equipment on the market, you can select a detector that can detect from 1 up to 7 different gases simultaneously so having a thorough assessment of the risks you could encounter prior to choosing your detection equipment is important.

What other equipment will I need?

A portable gas detector is a good start, but there are essential items that you may well need to ensure your complete safety. It is important that prior to entering a confined space, the air is monitored for gas hazards first. This can be done by either a hand aspirator and tubing or preferably by a detachable pump with ta ube attached. Entering a confined space can be a life-critical situation and it is important to know your monitor is working correctly. By putting a small amount of gas onto the instrument prior to entry confirms that your instrument is working as it should and this should be done every time prior to use. This procedure is called a Bump Test and can be carried out automatically, quickly and the results logged using a simple Bump Test Dock.
