How to Select the Right Gas Detection Solution

by Don Galman

There are many gas detection products on the market that might appear to be the same, but a closer inspection of specification, functionality and features reveals major differences in what products can do and the potential value they can offer. Similarly, individual applications are also unique in their respective designs, needs and processes undertaken.

Know your site risks

Before beginning to consider gas detection equipment, a risk assessment needs to be conducted. Any company employing staff has the obligation to conduct risk assessments to identify potential hazards and these can include potential gas, vapor or Oxygen deficiency risks. If gas hazards are identified, gas detection is applicable as a risk reduction method.

Identifying the prime objective

Depending on the processes being undertaken and the gases being detected, remote or off-site alarm notification plus event data logging/reporting may also be required for Health and Safety management records. Another factor impacting on the need for enhanced reporting functions might be regulatory compliance or a condition of insurance.

Ask the right questions

Having identified the primary objective, the suitable equipment is selected by asking a number of key questions. These fall into three broad categories:

  • The gases to be detected and where they may come from
  • The location and environmental conditions where detection is to take place
  • The ease of use for operators and routine servicing personnel
Identify the gases to be detected and where they may come from

The gases to be detected should be identified by the risk assessment, however experienced gas detection equipment manufacturers and their approved distributors are often able to help in this process, based on their experience of similar applications. However, it is important to remember that it is the end-user’s responsibility to identify all potential hazards. It is also essential to identify the potential source of a gas release as this helps determine the number and location of detectors required for a fixed gas detection system.

Consider the environmental conditions

The performance, accuracy and reliability of any gas detection equipment will be affected by the environmental conditions it is subjected to. Temperature, humidity and pressure levels at the location all have a direct bearing on the type of equipment that should be selected. Additional factors such as potential variations resulting from a production process itself, diurnal/nocturnal fluctuations and seasonal changes may also affect the type of device which is suitable.

Understand product functionality

The next area of consideration relates to additional product functionality. Aspects like wiring configuration are important, especially when retro-fitting into an existing application. If the apparatus is being integrated into a separate safety system, certain communication protocols may also be required such as HART®, Lonworks or Modbus®. Consideration will also need to be given regarding the requirement for local displays on transmitter units and local configuration of the unit and gas displays may also be a useful addition.

Measure the ease of use for operators and routine servicing personnel

Routine maintenance is another important consideration. Some gases and vapors can be detected with a number of different sensing technologies, e.g. Hydrocarbon gases with catalytic beads or Non-dispersive Infrared NDIR. Catalytic beads do not provide fail-to-safety operation and therefore can require a high frequency of routine maintenance, however NDIR based solutions tend to have a higher initial purchase price, but may require less routine maintenance. In-house resource to undertake such routine maintenance needs to be identified and in the absence of such a resource, budgeting for third party maintenance is an important factor in selecting the right equipment.

GasAlert Micro5 series (M5) Expert Product Review:

The Good:

Provides protection from 1-5 different kinds of atmospheric hazards, making it useful in a wide array of applications. It is available either as a standard toxic gas unit, a PID model for detection of VOCs or as an IR model for CO2 detection. It has both alkaline and rechargeable battery pack options, which are field-changeable, providing ease of use. You can also switch from diffusion mode to the optional built-in pump right in the field.


The Bad:

It is pricey, and the huge variety of sensor options, pump and battery options make choosing the right unit configuration a bit confusing for those not familiar with them. I recommend calling us at our toll free number (1.877.766.5412) for assistance in getting the right one.


The Bottom Line:

The GasAlertMicro 5 is highly configurable, which makes it suitable for the widest range of industries and applications. An example of some applications are Wastewater Plants, Pulp and Paper, Airlines, Landfills, Oil and Gas, Food and Beverage, Chemical Plants, Hazmat/Homeland Security and many more! It has many of the same user friendly features as the other units in the BW product line, so it is simple and easy to operate in the field and is a decently small size for its capabilities.


Full Review:

The extensive selection of sensors and user-settable field options in the GasAlertMicro 5 make it one of the most versatile units out there. The new pump design has a visible integrated filter window that allows the user to easily inspect the filter for dirt and debris. This also makes changing the pump filters quick and easy and still provides superior water resistance. AA alkaline batteries or the hot-swappable rechargeable battery pack options allow for fast, safe, and easy battery installation right in the field.

Regular maintenance is required on this model in the form of frequent Calibrations and battery replacement or charging. Bump Tests can also be performed on the unit depending on personal preference or when site safety regulations require it.

Built for rugged environments, the built-in concussion proof boot provides excellent protection against accidental bumps, scratches and damage; and it is water-proof, with an IP rating of 67 it can be submerged in water up to 1 m deep for 30 minutes. The real-time gas concentration is displayed continuously on the LCD so you will always know the current levels, even when the unit is not in alarm. The unit has a built in Datalogging feature, enabling you to retrieve a detailed and accurate history of conditions and unit maintenance if needed.

Calibrating the unit is required every 180 days by factory default but is quick and easy to perform; the procedure can be done in the field and only takes about 2 minutes to perform, and all you will require is a cylinder of calibration gas and a regulator. It is also compatible with the BW MicroDock II calibration and bump test station for those who wish to use a more hands-free, automated, calibration and bump test procedure.
