When catering for large events like weddings, conferences, or festivals, having enough fuel to cook all the food is critical. Gas cylinders provide the gas supply that powers catering equipment for cooking, heating, and keeping food at safe temperatures. Managing numerous gas cylinders at busy events takes advance planning and preparation.
Transporting Cylinders
You will need a way to easily move heavy gas cylinders from the storage area to appliances spread out over a large venue. A gas cylinder trolley is ideal for transporting multiple hooked-up cylinders. Choose an industrial-grade trolley with sturdy wheels that will not get stuck on uneven ground. Make sure the trolley has retention chains or straps to secure cylinders during transit, and position cylinders vertically and attach to the trolley so the valves are protected.
Storage
When choosing an event site, identify a safe and convenient outdoor storage area for spare gas cylinders. It should be far from public access in a locked cage or fenced enclosure. The storage area must have good ventilation to prevent the accumulation of leaked gas. Keep the enclosure cool and shaded from direct sunlight to avoid heating cylinders past the 125°F safety limit. Place cylinders upright on a firm, level surface like concrete or packed gravel, then chain cylinders to stable anchors to prevent accidental tipping.
Also group cylinders together by type of fuel (propane, butane, liquid propane, natural gas, CO2 etc.) and label them clearly for easy identification. Only keep the minimal amount of backup cylinders needed for catering operational capacity, about 10% spare fuel beyond what is actively connected to appliances. This reduces on-site storage hazards. Rotate spare cylinder stock by refilling empties back at your commercial kitchen’s bulk fuel cages.
Comprehensive Safety Protocols
Catering with pressurized flammable gas poses serious hazards if mishandled. Review all potential dangers and emergency protocols with staff before the event and ensure everyone wears proper safety gear when changing or moving cylinders: fire-retardant clothing with long sleeves and pants, closed-toe nonslip shoes, insulated gloves, protective eyewear and helmets.
Thoroughly inspect every cylinder, valve, pressure gauges and couplings for any signs of defects, corrosion or damage before use at the event. Use commercial leak detector spray to test fittings and immediately remove any cylinders found leaking from service. Prohibit all ignition sources like open flames or power tools that spark near operating or stored cylinders. For outdoor events, position cylinders far away from public areas, exits and routes used for emergency evacuation.
Hook Up
Use commercial-grade hoses, regulators, and couplings purpose-built for each cylinder gas type and appliance. Replace old hose assemblies prone to cracking or leaks. Ensure couplers have check valves to prevent backflow fires. Always attach couplers carefully by hand; never use tools which can overtighten and damage connections.
Apply coupling nuts gently until snug, then test for leaks and fix any found before opening cylinder valves. Unhook empty cylinders when gas stops flowing and replace with full standbys. Fully close cylinder valves and bleed hose pressure via outlet couplers before disconnecting. Cap cylinder outlets when storing empties to keep valves clean.
Supply Planning
Conduct an equipment audit to tally the total gas consumption volume needed for reliable catering operations. List every cooking, heating, and cooling appliance to be used and note:
number of each appliance type (ovens, grills, fryers, etc.).
BTU/hr gas input rating for each model appliance.
estimated runtime hours during peak event periods.
Multiply the BTU ratings by number of appliances and expected usage hours to calculate the total BTUs of gas capacity needed. Compare appliance gas needs to standard cylinder volumes to determine how many propane, butane, or CO2 cylinders must be supplied. Industry standard 20lb. propane cylinders hold about 465,000 BTUs for reference. Increase your cylinder count by at least 10% more as an emergency reserve margin.
Also allow for unpredictable factors like equipment failures or weather delays that could force appliances to run longer than planned. Monitor fuel gauges vigilantly and always swap out empties long before they fully deplete during critical cooking times. Confirm your vendor’s emergency re-supply delivery time if needing mid-event cylinder replenishments.
Placement
Spot gas cylinders around the cooking and heating area near appliances that need fuel. Keep them upright in a caged or chained enclosure to prevent disruption. Avoid heat sources like ovens that may raise cylinder temperatures over 125°F.
Place cylinders in visible areas with signs prohibiting public access and ensure there are open areas around cylinders so gas can dissipate instead of pooling if leaks occur. Position cylinders near appliance manifolds to limit hose lengths below 10 feet, and secure hoses neatly to eliminate trip hazards.
Monitor Use
Designate staff to monitor gas systems throughout the event. They should log start and end pressures for each cylinder to track usage rates. Check cylinders, couplings, and hoses frequently for problems like leaks, overheating or unusual nozzle ice buildup that can indicate issues. If you notice any faults, immediately stop use and have gear assessed by your gas supplier.
In Conclusion
Carefully managing gas cylinders prevents catering disruptions from running out of fuel or dangerous accidents. Planning adequate supplies, storage, transport, hook ups and monitoring lets your culinary team focus on serving delicious food to hungry guests all day.
