Fixed installation systems

Suppression systems

Fire suppression systems can include sprinklers and other types of fixed installations designed to automatically operate and suppress a fire.

Smoke Control Systems

These are complex systems that are provided for life safety of occupants, assistance to firefighters and property protection by clearing hot smoke and gases from the building. If you have one of these systems provided in your premises you should ensure you understand how it operates and that it is maintained in full working order. If your system is part of a larger system then you should liaise with other occupiers and building managers.

Dry and Wet Rising Fire Mains

The rising fire main is an important facility for the fire and rescue service in taller buildings. It consists of an inlet box where firefighters can connect their hoses, a pipe running up through the building, outlet valves on each floor level and an air vent at the top.

It is important that fire mains remain in good working order. Issues to be considered can include the following;

• The physical approach to the inlet box should be such that a fire engine can park within 18m with the inlet box in view.
• Prohibit car parking in front of the inlet box
• Secure the inlet box in such a way that firefighters can open the door without too much difficulty.
• It is advisable to lock the landing valves in the closed position, usually with a leather strap and padlock.

Foam Inlets

Foam inlets are special inlets usually fitted to provide an efficient way of extinguishing a fire in a basement or other area of high risk such as plant room. In many respects they look the same as rising main inlet boxes, but the door should be clearly marked "foam inlet". The risk area should be kept clear of obstructions to allow the foam to spread into the compartment.

Maintenance of Rising Mains and Foam Inlets

All types of rising mains and foam inlets together with associated valves should be maintained and tested on a regular basis. Although there are no recommended periods between maintenance checks it would be prudent to carry out an annual service.
