Introducing the GasAlert Clip Extreme 36 Month. Providing Three years of protection from H2S or CO, the water-resistant GasAlert Clip Extreme 36 Month has a built-in concussion-proof boot and is ideal for amphibious operations and high-moisture environments.

Equipped with two alarm levels and an internal vibrator, the GasAlert Clip Extreme 36 Month now features four visual LEDs, and a high-output audible alarm. The large, alphanumeric display provides instant notification of gas alarms, test status, life remaining (months then days then hours) and peak (maximum) exposures encountered.

The GasAlert Clip Extreme 36 Month's advanced microprocessor performs a full function self-test automatically on startup and on demand to verify sensor, circuit and battery integrity, as well as audible/visual alarm operation. Each unit also comes with built-in event logging.

Generating a permanent record of gas alarm events has never been easier. The GasAlertClip3 Extreme allows for effortless transmission of stored event data to a cordless printer or a PC for review and analysis.

Despite being loaded with features, the GasAlert Clip Extreme 36 Month is compact and light, which makes it comfortable to wear. Clip it to your lapel, pocket, belt or hardhat for unequaled protection.

Simply press the START/TEST button and the GasAlert Clip Extreme 36 Month is ready to use, providing three years of continuous, maintenance-free operation from the day of activation.

Standard Versions: units come ready for use; complete with integral water-resistant IP 66/67 concussion-proof housing, sensor, stainless steel alligator belt clip, test cap and instructions.

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.
