High Rise Escape Chute Systems

 

Risk Safety Systems range of Escape Chute Systems for the High Rise Buildings & Tall Structures.

This multiple escape chute system is installed inside a protected vertical shaft enclosure that is constructed in accordance to local fire code and designed to provide protection in the case of fire. This interior chute is constructed of 3 layers, the outer layer provides a speed restraining effect, and the inner layer supports the whole weight of chute.   

 

The chute is installed in segments at each floor level and within the fire-protected shaft, one segment of chute per floor, from the highest floor to the ground floor on the same vertical line.  One chute serves many floors and occupants can gain access to the chute at each floor.

 

 

Escape Chutes:

 

The escape chute system for multi-entry applications is divided into segments or sections in accordance to the number of storey's within the  building, minus the top storey. The highest storey will not have a chute segment. Each chute segment is held within the pre-cut floor hole using the chute top stainless steel ring.  The lower end of each chute segment penetrates 30/40 cm into the next segment of chute of the following floor.  The chute segment of the ground floor finishes 80/90 cm from the ground level in order to allow the person descending to free himself from the chute, with/without the help of an assistant.

 

Example of chute calculation:

 

Assuming a building with 10 storey's inclusive of ground floor (first storey), each storey is of 3 meters high, would need the following length of chute:

 

   •  10 storey minus the highest storey = 9 chute sections.

   •  9 chute sections  = 8 separate chutes

   •  Each chute section =3 + 0.35m = 3.35m

   •  Therefore 8 chute sections =8 x 3.35m =26.80m

   •  The ground floor chute section = 3 – 0.85m = 2.15m

   •  Total length for 9 chute sections = 28.95m

 

9 holes would be required, from the floor of the highest storey to the floor of the second storey.   The multi-entry escape chute installation consists of  3 layers of chute fabric: - the outer layer is heat resistant too 650 degrees and a melting point of 800 degrees, middle layer acts as the break and will slow the speed of descent, the final inner layer is the comfort and anti friction layer.

 

Fire Resistance Door:

 

The entrance at each precinct is protected by fire resistance door of at least RF30 (RF 60 is usually installed). The minimum width of the door is 80cm and the height is 2m.

The door is always closed under normal condition. The doors for the upper floors are open inward and must never pass above the metal ring of the chute frame.

The door for the ground floor is open outward to ease final escape. Anti-panic bars can be installed on the doors for ease of evacuation.

 

Other Essential Elements:

 

   • Emergency Exit Lights – each floor

   • Emergency Lighting – each floor

   • Emergency Light - each floor

   • Service Lights – each floor

   • A set of Rings (iron ring frame, aluminum ring, adjusting rubber profiles) – each floor

   • Overpressure air supply system – one unit

   • Inter-com system – each floor

   • Smoke Hoods  – each floor
