 Commercial/Residential Escape Chutes


Escape Chute Systems - Commercial/Residential Escape Chute


International Safety & Supply is a global Supplier of custom designed escape chute systems

manufactured by  Survitec/Risk Safety Systems located in Houston, Texas USA.  


Escaping from danger or fire has never been this easy

Escape chutes provide a means of emergency exit that permits rapid, mass evacuation from high rise structures during life threatening emergencies. It is uniquely designed to provide a relatively safe and quick method of vertical or inclined escape and is always accessible and ready for use.  it provides a unique solution for vertical escape in sometimes difficult conditions during an emergency evacuation.


A simple Escape System

The construction of the chute helps to protect the evacuees from heat, fire and is used for rescuing the old and the handicapped, it enables unconscious patients and those on stretchers to be brought to safety with very little training. This is sometimes difficult or impossible using traditional rescue equipment.

Three way Protection—The escape chute consists of three layers. The outer layer is of a material that will not ignite.  The middle layer helps to regulate the speed of decent, inner layer reduces friction.

Multi-entry and Single-entry Escape Applications


Multi-entry High Rise Building Escape Chute System


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


Integrated System:

When the building is equipped with the emergency power supply (EPS) system, the various supplementary devices such as over pressurized fan, the inter-com system at each level and emergency lights could also be integrated into the multi-entry escape chute system to facilitate the better control during evacuation process.  The building automation system will auto-start the various devices for ease of the evacuation process.








Single Entry Residential Escape Chute


Measurements for custom designed single entry Residential Escape Chute Platform


The single-entry chute platform is custom-designed for each application. Some installation sites may require minor alterations to the fabric of the structure to accommodate the custom-designed platform.


The platform can be supplied as a permanent or portable installation. The portable escape chute and container are stored, in the case of an emergency the chute and container are placed into the chute cradle, this a permanent fixture and is located on a window balcony, hand railings or another suitable location, RSS agree position before undertaking of workscope.  In all cases design drawings are prepared and issued to the customer for approval.   


Buildings vary significantly in terms of:


• Design

• Height

• Size

• Structure

• Construction


RSS would need to know where the proposed location for the single-entry chute would be. This is required for our design engineer’s and would include the following:


•  Where would the platform be installed at a rooftop, balcony, window, corridor, etc.?

•  What are the building materials at the installation site, tiles, marble, cement, brick, etc?

•  Are there any limitations or constraints to the installation area or floor space for the installation of the platform.

•  Photos or simple sketches of the installation would be helpful and would greatly assist our design team.


RSS design department work closely with the customer to ensure we have all the necessary measurements of the proposed installation site prior to design.  

Correct measurements will save time and money, especially during the installation.


Window Unit Installation:


•  Would the platform be installed outside or inside of the window/building?

•  The distance between the floor and top of the window parapet.

•  The distance between the window and the next window or wall (left and right).

•  The distance between the ceiling (wall/floor) and the window.

•  The distance between window frame horizontal (inner) when window is open.

•  The distance between window frame vertical (inner) when window is open.

•  The width/depth of the window parapet wall.

•  Is there any decoration outside of the wall (obstruction), the distance between the obstruction and the wall?

•  Allowable floor space inside of the window for the platform.

•  In which direction the window opens: slide, inward, outward, etc.

•  The distance between the window parapet to the ground level minus 80cm.
