Keep your Portable Gas Detectors working well

If your gas detectors readings are not accurate, they are not safe

Check the list below for your best practices to ensure your Portable Gas Detectors are well treated

Fresh Air calibrate before you use them

There is no reason to not calibrate. You can calibrate any time in Fresh Air.

Complete a functional Bump Test regularly

It will determine your portable is working correctly. If Bump test failed, calibrate it.

Maintain your Portables free of dirt, always

Keep them away from dirt, dust and water, it could block input emissions in the sensors area.

After high exposure to gas, perform a Bump test

Sensors can be poisoned by other gases which are absorbed into the sensor/s.

Keep your calibration certificate up to date

Certified calibration every 12 months.

Store your portable in a clean environment

Avoid dust, dirt and water impact in the storage location.

How safe is the transportation and logistics of the COVID-19 vaccine?

Gas Detectors CO2 as relevant equipment for Covid-19 vaccine logistics.

The Pfizer COVID-19 vaccine is currently being transported and stored worldwide and must be in low temperatures (-70C as a minimum) packed into containers of dry ice, this is a solid form of carbon dioxide (CO2) and cryogenic freezers (liquid nitrogen). This includes local transportation through hospitals, laboratories, and pharmaceutical companies.

This consequence is that this can might turn into a hazardous environment coming from the huge amount of dry ice which is substantial for this circumstance. Therefore, it is relevant in terms of safety equipment that for safety of your staff you have either portable or fixed CO2 gas detection.

The small quantity of dry ice is innocuous, however comparing to a big number of containers needed for this specific logistic event the creation of CO2 gas occurs. Thus, collective gas emissions could be enough to be a potential safety hazard to personnel in the area (Transportation of COVID-19 Vaccines Requiring Large Quantities of Dry Ice., 2020).

For spaces with a high level of risk of CO2 concentration (usually above 2%), the installation of a CO2 monitor should be required.

Our experience and wide range in the Gas Detection industry in Australia provides the solutions needed for these environments.

For a complete gas detection system solution for this issue, Gas Detection Australia recommends the I-Gas portable for portable applications and the IR Gas CO2, Mute 6182, LT-70 and Controller 4022 for fixed applications.

Importance of Calibration

Calibrate your Gas Detector Systems to ensure realiability

Your Gas Detection System is a highly important part of your safety and also your staff’s safety as well as assisting in keeping operating costs lower by detecting leaks when they occur.
Your gas detectors can be damaged in several ways.
The environment, where there is any of the following: Dirt, Dust or Moisture, these types of problems will impact the detectors' ability to do its job. Consequently, any of these events can cause a range of damage from, blocked sensor heads, damage to sampling pump or sample lines. In addition, when the environment is too hot or too cold could also impact negatively to the sensors in order to measure properly, also sensors will also naturally degrade over time.
In conclusion, The primary reason for functional tests and calibration tests are to assess how the sensor is working and is it within calibration, If the sensors don’t perform as they should then it will show you that you have some sort of event and you can start looking for the cause. Maintenance or lack of is the leading cause of failures that we see in sensors today.
Therefore, the need to calibrate your gas monitoring system regularly is critical. It is recommended to do a 6 monthly functional test, then a full calibration every 12 months.
Remember irregular maintenance could potentially have many repercussions from the safety of people and also legal, especially in the event of an accident or near miss.

Infrared Gas Detector: How does it work?

Our Infrared Sensor works via a system, which includes the light sources (transmitters) and light detectors(receivers), which function, identify possible Carbon Dioxide and Refrigerant gases leak. Once a gas leak occurs, it will be altered by the lights to recognise the type of gas.

One of the main benefits lies out in not losing sensitivity, not even a long-time exposure.

Figure 2: IR-GAS Gas Detector product.

Mute Switch: Function and Benefit

The Mute Switch function is in charge to mute the Sounder/Flasher (AVR 20RM) via a switch. The process starts when the Mute Switch receives the 24 VDC alarm signal from a gas monitoring controller. The Mute Switch works with the capacitive touch button, which mutes the sounder of the connected AVR 20RM. This remains flash until the gas alarm is deactivated and consequently the Mute Switch reset. The Mute Switch has two-stage alarms and is synchronised allowing the user two locations for the Mute Switch in a room for safety purposes.

Figure 3: Mute Switch product.

The Two-Channel Controller: Function and Benefit

The Two-Channel Controller main feature lies in the two points of gas detection design and the success of the direct connexion to gas sensors. It is a great benefit for the user due to the easy installation and considerably less cost.

Safety is always our Priority

Our General Manager Rob Whittet, tell us about the importance of Safety in Gas Detectors as relevant equipment in the Gas industry.

When gas leaks occur it only takes seconds to spread into a large room. It is highly difficult to detect if a portable or fixed gas detector is not used to detect the leak. This can impact negatively on employee’s health that range from slight headache to even death, not to mention the harm to the environment and your business.

The effects of gas exposure of unseen danger and environments that you do not think could cause a problem can be long lasting. Gas exposure can be as simple as sitting in a room with too many people and not enough fresh air movement or confined spaces, this will cause the Carbon Dioxide levels to rise and your staff will leave feeling drained and maybe with a headache. You must remember that gas can come in many different variants and therefore has many different outcomes when something goes wrong. These can range from a headache to an explosion because someone left the gas turned on at a stove or gas point in a lab or even a refrigerant leak from an air-conditioner.

In order to prevent the consequences of a gas leak in a company, the appropriate Process Hazard Analysis (PHA) must be applied. Every process for prevention is highly valuable, and companies must cover every process in extreme detail.

In May of this year, a well-known Chemical company in Queensland had a massive leak of Carbon Dioxide and Nitrous Oxide gases into the atmosphere, due to equipment failure, which costed the company more than $5 million on repairs and reassurance to the local surrounding community.

There is no risk when the correct PHA performance is applied in companies. Either a portable or fixed gas detector system is essential for the safety of your employees, helping to identify a gas leak in an early stage, preventing a significant damage, including illness, serious injuries and even death.

NDIR vs MOS

Infrared (NDIR) vs Metal Oxide Semiconductor Sensors (MOS)

When using a Variable refrigerant flow (VRF) system in an enclosed space there is a risk of the charge leaking into rooms. Depending on the refrigerant type and charge this can lead to asphyxiation via oxygen depletion as well as dizziness, headache and confusion from toxic gases. Early warning without false alarms are essential for safety of people utilising the rooms.

When using a detector consideration must be given to not only price but the cross sensitivity and amount of false alarms that it has the possibility of creating. Other items to be considered are the accuracy, reliability, maintenance requirements and expected life span. The other items to take into account when selecting a VRF system unit is the aesthetic look and also the other items that may be used in the room such as Volatile Organic Compounds from items such as cleaning agents, aerosols and item like nail polish.

Figure 1, Sensitivy Spectrum in Sensors Technologies Diagram

The Infrared sensors are less likely to be affected by items like humidity and temperature changes. Due to the fact that metal oxide sensors have a “Broad” sensitivity they cannot see just one gas but multiple which lends itself to false alarms along with the required high temperature that they need to see the gas.

The NDIR sensor does not have the problem of cross sensitivity and reactions to humidity and temperature, it also does not age as quickly as its MOS counterpart. Poisoning is also something that will not happen when using the NDIR version as the gas does not come into contact with any active part of the sensing stream.

In conclusion the NDIR sensor will work for longer and be more accurate with less false alarms, which will bring your overall cost down due to servicing costs and call outs due to the false alarms. The most reliable and cost-effective solution is the NDIR sensor.
