Selection of Gas Detection and Instrumentation for Confined Space

It is generally found that the most “suitable” gas detector for confined space does not come from any one manufacturer. It is the device that is the best match your requirements for the operational needs.

To meet these needs, the price is not the only factor for consideration. It is the specification of the gas detection and instrumentation that is more important. The functionality of the detector that meets the purpose is also critical. The data collected from the monitoring process and early detection will enable you to make an informed decision. This is especially crucial if there is a high level of toxic gases in the confined space. Selection of detector can be based on the factors such as:

Specification of Gas Detection and Instrumentation

Sensitivity level: Does the detector capable of measuring and tracking the known and potential hazardous substance which may be present in the confined space to be monitored

Gas Detection and Instrumentation Classification

Classification for Intrinsic Safety: Detector purchased for use in a confined space, hazardous excavation or other newly developing environment comes in handy as it can be used to detect potential presence of flammable, toxic or explosive gases.Hence, this detector should carry a Classification of Intrinsic Safety.

Diffusion Method: Diffusion instruments use the natural air currents to bring the atmosphere being sampled to the instrument. They are often used to monitor the work area. Sample-Draw kits will enable the diffusion instruments to sample from remote locations. This is useful for below ground stratification of gases tests such as down a manhole or utility vault.

Alarm: Majority of the new detectors have three types of alarm function; audible, visual and vibratory. Alarms should be loud, highly visible and powerful to get the attention of the user.

Durability: Is the detector able to withstand the abuse in the course of daily usage? How well is it protected from the effects of radio frequency interference (RFI) and electromagnetic interference (EFI)? Does the detector able to weather the extreme in temperature and is it dust and water-resistant?

Power Source: Detector is normally using Alkaline batteries, rechargeable batteries or both.

You can check the consideration of the package which includes accessories, calibration frequency, product warranty, after-sales service and technical support. Overall evaluation of the operation of the gas detector will help to ensure a suitable detector is selected.
