Industrial fryers are cookers commonly used in the food industry to produce consumables, such as breaded meats, potato products and pre-cooked snacks, for example. They contain large amounts of cooking oil (up to 19,000 litres or 5,000 US gallons) and operate at temperatures of up to 354°C (670° F).
Machinery spaces in general terms are areas where complex machinery moves at speed, often close proximity in, generates heat and requires significant quantities of oil to optimise performance. The oils, lubricants and hydraulic oils used in machinery spaces and plant rooms can all become flammable even though they are comparatively non-volatile liquids and have flash points higher than normal temperatures.
Modern cities depend on the integrity of cable tunnels for a host of data communications, power distribution networks and transport infrastructure. Located underground, tunnels can extend for long distances and are part of the vital information and energy infrastructure that serves commercial, industrial and residential needs.
Commercial spaces, such as offices, retail, leisure and hotel contain a very varied mix of fire hazards. Such places of business can be occupied by vastly different number of people and varied critical assets at any one time, each representing a challenge for fire safety.
