In August we had the pleasure of Stephen Lock from All Controls Australia visit our International Headquarters (S&S Northern) in the UK.
All Controls are the distributor for OGS products in Australia and New Zealand. Stephen Lock is the Technical Sales Manager for Gas Combustion products for All controls and has extensive knowledge in our product range.
It was a great for Stephen to meet the team and show him some of our new product developments for later this year, as well as reflect on the success of the OGS product range in Australia and New Zealand.
Always a pleasure to catch up with an industry legend.
Ensuring Safety with Gas Proving Systems in School Classrooms
The safety of students and staff in school classrooms is of paramount importance, and one crucial aspect of maintaining a secure learning environment is the effective management of gas systems. Gas proving systems are indispensable tools that help ensure the safety of everyone within the school premises, particularly in science laboratories and classrooms where gas appliances are commonly used. In this blog post, we will explore the significance of gas proving systems in school classrooms and their role in preventing potential gas-related hazards.
Understanding Gas Proving Systems
Gas proving systems, also known as gas guards or gas checks, are designed to monitor and control gas flow to various appliances and outlets. Their primary function is to verify the presence of gas pressure before allowing appliances to operate. In a school setting, these systems are used to manage gas supplies to laboratory equipment, such as Bunsen burners, gas taps, and other devices commonly found in science classrooms.
How Gas Proving Systems Work
Gas proving systems typically consist of sensors, control panels, and alarms. Here’s how they work:
1. Pressure Transducer are located on the gas solenoid valve or pipework. These Pressure Transducers detect the presence of gas within the system.
2. Control Panel: The Merlin 1000V control panel is the central processing unit of the gas proving system. It receives signals from the sensors and processes the information to determine whether gas is present or not, also if a leak has been found.
3. Detectors: Gas proving systems can be equipped with Gas Detectord that are triggered when gas is detected within the air. These detectors alert occupants and staff to a gas leak and isolate the gas solenoid valve.
Advantages of Gas Proving Systems in School Classrooms
1. Safety : Gas proving systems provide an additional layer of safety by ensuring that gas appliances are only operational when gas is present. This helps prevent accidents and potential gas leaks that could lead to fires or other hazardous situations.
2. Compliance : Many regulatory bodies and local authorities require educational institutions to have gas safety measures in place. Gas proving systems help schools comply with safety regulations, avoiding legal consequences and ensuring a safe learning environment.
3. Peace of Mind : Teachers, staff, and students can focus on their work and studies with the assurance that gas-related risks are minimized due to the presence of reliable gas proving systems.
4. Early Detection: Gas proving systems can detect even minor leaks that might go unnoticed otherwise. This early detection capability can prevent situations from escalating into emergencies.
Implementing Gas Proving Systems in Schools
To effectively implement gas proving systems in school classrooms, consider the following steps:
1. Assessment: Ensure you meet the requirements of AS5601.1.2022. Identify areas where gas proving systems are necessary for safety.
2. System Selection: The OGS Merlin range has various gas proving systems that meets your school’s requirements and conforms to safety standards.
3. Installation: Engage professionals to install the gas proving system. Proper installation ensures accurate detection and reliable operation.
4. Staff Training: Train teachers, laboratory staff, and relevant personnel on how the gas proving system works, including recognising system alerts and responding appropriately.
5. Maintenance: Regularly inspect and maintain the gas proving system to ensure it remains functional and accurate. Schedule periodic servicing to keep the system in optimal condition.
Conclusion
Gas proving systems are invaluable tools for maintaining the safety of school classrooms, particularly those equipped with gas appliances. By ensuring that gas is present before allowing appliances to operate, these systems play a pivotal role in preventing potential gas-related hazards. The peace of mind, compliance with safety regulations, and early detection capabilities offered by gas proving systems contribute to a secure and conducive learning environment for students and staff alike.
What is a Gas Interlock system?
The Merln 1200S Gas interlock system ensures the ventilation is running at its required level. If the ventilation fails, or is turned off the gas supply is isolated.
Is there a regulation?
Yes! AS/NZS 5601.1.2022. This standard covers general gas installations. Where required air supply to an appliance relies on a mechanical system, there shall be an interlock to cause the gas supply to the appliances to be shut off upon the failure of the mechanical air system.
It mentions “the interlock shall fail safe and it shall be proved in the no-flow state prior to start-up”
It also mentions that the interlock “be of the type that will sense actual air movement” such as an air pressure differential switch.
Can I just wire an Air Pd switch to a gas solenoid valve?
It’s not recommended. An air Pd switch can get stuck due to grease and moisture, this means the gas will always be on with no means of isolation.
Also if it’s windy weather the air Pd switches are prone to click off and on causing the gas to trip off and on becoming very irritating for the kitchen staff. Also flames can easily extinguish and create gas leaks.
What is Best Practise?
Install a OGS Merlin 1200S interlock system. It checks the Pd switch changes state when the ventilation turns on and then allows the gas on. It eliminates nuisance tripping it has a built in delay to ensure windy days don’t affect the operation. Interlock systems can also be connected to fire alarms and fire suppression systems.
The Merlin 1200S interlock system has a built in emergency stops as standard to isolate the gas in the event of an emergency and are recommended to be installed with our GoldSeal gas valves.
Our kits are simple and very cost effective. They include a 1200s panel, 2 x air pressure differential switches, 1 x remote emergency shut-off button and options for a Goldseal gas solenoid valve Sizes ½” to 2″.

There are significant updates in AS/NZS 5601.1 2022 from the previous standard that affect persons carrying out gas installation work.
Clause 5.2.11 Provision of fire emergency isolation for multilayer pipe. Where Multilayer Pipe is used as apart of the consumer piping, the installation shall be fitted with a system that will shut off the gas supply when the fire safety system operates.
The OGS Homesafe has been deigned specifically for this clause. When the fire system the OGS Homesafe will isolated the gas supply. When the fault is resolved, the OGS Homesafe will perform a gas proving test on the downstream pipework to ensure there are no gas leaks. Then allow gas back into to the property.

It’s been an awesome 5 days travelling around NZ demonstrating our latest Oceania Gas Safety product ranges to our customers and consultants. After years of being unable to travel, Craig was finally able to visit from the UK and it has been a pleasure showing him the country I am lucky to call home along the way.
We can’t wait to have you back next year.
