Electrical Cable Enclosures

For reasons of compartmentation, practicality and convenience, electrical cables and pipes for other essential building services are frequently installed in corridors and then sub distributed to adjoining rooms and compartments. Corridors also serve as access and escape routes in the event of fire. Cable installations are therefore exposed to special risks and are worthy of particular concern. Electrical short circuits are still a major cause of fire, and smoke and toxic gases often accumulate in access and escape routes, further endangering both building occupants and emergency personnel

Tested and proven solutions are best for effective fire protection:

1. PROMATECT cable enclosures for exposure to fire from the inside

PROMATECT cable ducts inhibit and prevent fire and heat from spreading outside duct to other compartments, such as corridor escape routes, which remain usable for a certain period of required time.

2. PROMATECT cable enclosures for exposure to fire from the outside

PROMATECT cable ducts are designed to sustain the functionality of cable installations and also protect surrounding areas. Certain services, such as electricity for example, are required to sustain emergency/exit lightning in some critical areas.

Ventilation & smoke extraction enclosures

Fire protection requirements for ventilation ducts are directly related to their design function, the nature and behaviour of the fire and the construction materials that fuel the fire load. The fire resistance performance of the ventilation duct itself also plays a critically important role.

It is possible to prevent fire spread from one fire compartment or from one floor to another — and along stairways and general access corridors — only if all building materials and structural elements share a common fire classification and fire resistance rating.

Typical steel sheet ducts do little to meet internationally accepted fire protection compliance. They heat and deform rapidly from the effects of fire. In certain circumstances they even accelerate the spread of flame and smoke.

Ventilation ducts up to 180 minutes fire resistance

Sheet steel ducts from an independent manufacturer can be lined or sheathed with PROMATECT fire protection boards or the duct can be fabricated entirely from PROMATECT fire protection boards.

When existing steel sheet ducts are lined, for example, with PROMATECT fire protection boards it is necessary to satisfy additional fire protection requirements for change in use status.

A more economic solution, however, is achieved by specifying and installing tested and proven PROMATECT ventilation ducts from Promat, the world leader in professional fire science technologies.
