Last time, we talked about inert gases and how your venue can safely implement monitoring procedures for your venue’s gas systems. It’s important for all staff required to service cold room dispensing systems to learn the potential hazards and correct procedures in maintaining these systems. Learn more about this side of hospitality management by enrolling in one of our comprehensive hospitality courses.
1. Design, assembly and diagnostic tests including position and design of dispensing systems
Essential design specifications such as safeguarding dispensing systems from overstress and backflow, as well as being capable of segregating critical areas as required complying with AS5034. By enhancing system design and improving consistent management, the hazards involved with an inert gas dispensing system will be decreased.
2. Location and air flow of supply systems including gas detection and emergency procedures
The recommended location of all inert gas (cylinders and mini-bulk) systems is on the exterior in a properly ventilated area. Prerequisites are provided for the ventilation specifications of a cellar. The prerequisites take effect where the gas is located as well as whether your area will need supervising. Most venues will require a monitor in the cellar and cool room to comply with AS5034, even in the instance that your gas is stored outside. Storage areas that are unable to abide by with the ventilation requirements will need gas monitoring and ventilation devices.
3. System operation and maintenance including maintenance records
Consistent weekly leak checks must be conducted by the venue and more specialized every 6th-month servicing is necessary, for example. Calibrating your monitor and check safety valves every 12th-month maintenance, including a pipeline pressure test, is also expected to meet AS5034. All maintenance records are required to be kept for a minimum of two (2) years.
Systems require clear labelling and should be correctly signed. Examples of signs required include warning notices, operating directions, inert gas warning signs, safe operating procedures, isolation valves, safety valves and pipeline contents.
5. Training of staff and contractors
AS5034 necessitates all employees to be properly trained in manual handling procedures, the components and dangers of inert gases, and the appropriate use of Personal Protective Equipment (PPE). There are also training prerequisites for any contractors entering a venue.
A space which may possibly be subject to the leakage of inert gases can include cold rooms. The atmosphere should be inspected by taking a look at the gauge close to the door and listening for an alarm. The noise from the alarm will be clear when the oxygen concentration in the atmosphere deviates outside the safe limits. The area must not be entered into and management should be alerted immediately.
