Gas Detector Considerations

There is a reliance from numerous people upon a gas detection system to keep workers safe at work or to protect the site itself. Installing the right type of detection system isn’t straightforward yet critical it’s specified correctly. With various factors involved in the purchasing decision, we have listed several factors for you to consider.

We provide a reliable nationwide service co-ordinated from our dedicated help-desk team that will ensure works are planned at a time that is convenient for you.

Gas Hazards

Some gases will naturally rest high or low in a room depending on their density. This will impact the decision on where to position the gas transmitters.

Environmental Conditions

Is gas detection taking place in humid, under pressure or high temperature environments?


Air flow will impact whether gas reaches the sensor.


Threshold limits – how many alarm levels are required?


Outputs to shut down the system or activate ventilation.

Gas Detector Capabilities

Continuous Area Monitoring

To protect premises from threat of explosion or damage. Systems activate ventilation, shutdown the process or turn on fans to reduce threat of gases.

Local Alarms for Personal Gas Exposure

Allow people to work safely and confidently until risk of dangerous gas inhalation or explosive atmosphere occurs. Nearby alarms alert to possible danger.

Process Gas Sampling

Gas analysers are used in research studies or field measurements for profiling the composition of gas samples or even, implementing accurate dosing or control systems.

Gas Hazards in Breweries

In breweries, there are specific gas hazards that your staff might face. It's essential to be aware of these dangers and take appropriate measures to ensure their safety.

High Risk of Carbon Dioxide (CO₂) during the Fermentation Process

During fermentation, the release of carbon dioxide can pose a serious threat. Symptoms of CO₂ exposure range from headaches and difficulty breathing to increased heart rate, elevated blood pressure, coma, asphyxia, and even fatalities. To monitor CO₂ levels effectively, we recommend using either the CTX300 or OLCT100 detectors, or a combination of both, connected to an MX43 control system with an optional beacon for visual alerts.


Risk of Oxygen Depletion in Confined Spaces

Confined spaces in breweries can experience oxygen depletion, leading to weakness, fainting, coma, seizures, and potentially fatal consequences. To address this risk, a fixed oxygen gas detector is necessary. For your situation, we recommend the OLCT100 gas detectors connected to an MX43 control system, along with a suitable beacon for visual warnings. Additionally, personal gas detectors can be provided to ensure your staff's protection from oxygen depletion.

Ammonia Leak Risk in Refrigeration Process in Compressor Room

Ammonia is commonly used in the refrigeration process in compressor rooms, but it poses dangers such as skin burns, severe headaches, and vomiting. The main threat, however, is the potential for an explosion. To safeguard your staff from ammonia leaks, we recommend implementing a sampling system. This system consists of multiple lines connected between the sampling system outside the room and a filter at each sampling point. Due to the noise level in this environment, a visual beacon, such as a flashing light system, can be connected to the sampling system for enhanced safety.

Methane Leak in Boiler Room

In the boiler room, the presence of methane gas can lead to asphyxia and potential explosions. To protect your boiler room from this explosive gas, we suggest utilising a gas sampling system. This system collects samples from various locations, filters them, and carries them to a centralised sampling system for analysis. Alarms and data screens can be positioned safely outside the room, allowing users to be alerted without entering the dangerous area.

Case Study - CO2 In Breweries

Learn about the hidden dangers of carbon dioxide (CO2) in breweries and the essential measures to ensure safety. Uncontrolled levels of CO2 can lead to severe health hazards, even suffocation, making proper monitoring absolutely crucial. Discover how the accumulation of CO2 during fermentation and storage processes can create hazardous pockets. Implementing a comprehensive gas detection system, including fixed CO2 sensors and personal detectors, is crucial to protect brewery personnel.

Case Study - a1-cbiss Engineer a Brewery Carbon Dioxide Monitoring System

Discover how a1-cbiss helped two major breweries in the UK ensure health and safety compliance with a tailored Carbon Dioxide monitoring system. With elevated CO₂ levels during fermentation, a1-cbiss designed a solution using advanced gas detection technology. The system provides visual warnings, integrates with ventilation systems, and offers real-time data acquisition and reporting.
