This could be monitoring VOC ( Volatile Organic Compounds) levels pre and post filtering, Solvent Vapour (LEL) monitoring in drying ovens, Ventilation control in Car Parks and building etc. Typically gas detection systems in this section are used to monitor and either alarm or be part of processing control.

Besides asphyxiation, flammable gases are generally not directly toxic and therefore, the strategic position of detectors is where the gas is expected to accumulate based on its relative density to air (heavier or lighter). Gas detectors are usually categorised into three distinct groups for placement: Plant Protectionįlammable gas detectors are typically categorised into this group.

When contracting a company to undertake the management of the gas detection system, ensure that this is part of the scope of their ISO 9001 quality system. Finally this article also highlights the importance of effective maintenance of your gas detection systems by engineers who can demonstrate competency of the system through training and certification.

Furthermore this article also helps with the different solutions that IGD has for gas detection, for example the use of our Addressable Sampling Systems, ideal for hard to access places or where traditional detectors would not work examples could be Clean Rooms (Please see our case study for Sampler Systems). The following article is intended to bring together UK industry legislation and guidance notes, to help advise you with the consideration and placement of IGD gas detection systems.

This is due to the complexity/speciality of gas detection due to the vast amount of gases being detected, over 400 gases with varied amount of properties and environmental influences factors, such as heat, that affect gases in different ways. Gas Detection systems only have industry approved best practice guidance notes for locating, placement and number of gas detectors. Unlike fire systems that have a specific standard for installation and placement, EN54, there is no similar standard that exists for gas detection. ⇓ Gas Collector Cones and Splash Guards Introduction: By positioning the measuring hose correctly, you can also make a correct measurement at different heights to chart all risks.⇓ Calibration and Service Requirements for Gas Detection Systems This allows you to make an appropriate risk analysis and make the right strategy and PPE choices based on the measurement results. This means that you can take a measurement from a safe distance so you have an idea of which gases will be present in which concentration before you are exposed to this environment. A sampling hose may be connected to extend the reach. This means that the device is constantly drawing in gases. Pumped instruments are equipped with a built-in sampling pump. Since there is no forced flow of the gas to be measured, this device is not suitable for taking measurements remotely, but they do accurately identify what’s present in a given location. This also means that a diffusion gas detection device is only able to measure the concentration of gases at the location where the device is located. Diffusion means proportional spread of molecules over the available space (from high concentration to low concentration). The sensor is exposed to the ambient air and will measure the gas by means of the diffusion principle. A diffusion gas detection device works, as the name suggests, on the diffusion principle.
