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.
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.
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.
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 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.
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.
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.
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.

Rugged, reliable and built to provide reliable performance, simplicity and durability. The BW GasAlert Quattro combines a nice range of features with simple one-button operation. Flexible battery options mean the unit it always ready to work.
It is higher priced than the MicroClip XT but the features and battery options make the extra dollars worthwhile to me. The user-options can only be set via the IR interface and the software, not in the field.
The Quattro is one my favourite models. It is so simple to use, with reliable sensors and the ability to change battery packs in the field makes this unit one of the best units out there in my opinion.
It is a good fit in virtually any application where toxic and combustible gases are a concern, such as Oil & Gas, Utilities, Municipalities, Refineries, Steel Mills, Pulp, Paper and more. The sensors in the Quattro were selected after numerous field trials because they give the best overall operation and reliability.
The new IntelliFlash feature provides visual confirmation of the operation and calibration or bump testing compliance. 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.
Multiple User-options, such as flip display and bump test frequency for example, can only be set via the IR interface and the software, not in the field. This is both good and bad in that the options can't be changed by the everyday worker, which is great if you are the safety guy and have the detector set to match your company guidelines, but inconvenient for those users who like to make adjustments in the field themselves.
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.
