www.mobiltex.se www.escapeconsult.biz http://youtu.be/BCtbDAMnM-M http://escape-chutes.blogspot.sg/

Installation Characteristics The multi-entry escape chute system is permanently installed inside a vertical shaft/duct within the building and it allows occupants gain access to the chute at each floor where several levels can be simultaneously evacuated inside. These multiple-chutes are located inside the enclosed fireproof shaft, with doors that automatically close after use. One segment of 2-layers chutes per floor, from the highest floor to the ground floor on the same vertical line, no restriction of length or height. The multi-entry escape chute system is normally built-in at the design stage before the building is constructed and strategically located where occupants can easily and safely gain access to during emergencies: · at the smoke free area at the central core building, · at any strategic area(s) inside or outside the building. At the design stage, the provision of a vertical rectangular duct/shaft similar to a "lift shaft" that has 3 walls and entrance to that floor for the installation of the multiple chute system. Place a metal floor deck across the shaft and cut a square hole on the floor deck for the fitting of the frame and the chute. If there is no pre-provision of the vertical duct/shaft for the installation of the multiple chute, the possible installation is to covert available floor area into a precinct (small cubicle room), from the highest floor to the ground floor to safe exit on the same vertical line with no hindrances of piping, wiring, air-con ducts, etc at each level of ceiling floor. Possible sites/locations: · Reserved passage or corridors, · Spare lifts structure, · Cubicle toilet, · Pantry or store room, · Space at the central core of fire staircase, · Extension of a rectangular structure out of the building similar to a lift shaft.

Precinct (Small cubicle room) Construct 3 sides of walls and entrance with bricks at each floor to make a small room at every floor. The precinct (small cubicle room) requires a minimum area of 2-sq. m. at each floor of a building. The provision of the precinct from the top storey through the ground level on same vertical line has similarity to a rectangular vertical lift shaft constructed inside or outside the building to serve every floor. The construction of the precinct has also got the similarity to that construction of fire staircase but without stairs in accordance to country’s local fire and building code. The precinct is constructed with the shortest side of the wall that is of at least 1000mm and the longest side of the wall is of at least 2000mm. The wall of the precinct must be constructed with fire resistance materials of at least RF120 (120 minutes resistant to the fire). Materials will be of MO category. A wall having a ceramic brick of 9cm thickness protected with chalk both sides are considered as acceptable.

Civil Engineering Requirements

• Inside the precinct (small cubicle room), cut a square hole on the concrete floor to fit the square aluminum alloy chute mounting frame and the chute. The square holes and the Slabs within the Fire Chute duct will be fabricated as shown on the Fire Chute Design submitted by us.

•The Slab design becomes extremely important in the present scenario where modern techniques

such as Mivan and Mascon are used in building construction. These systems while being extremely

efficient are much less flexible in terms of incorporating changes once the slabs have already been

cast. Hence it is very important to know the exact slab design before the slab is actually cast. Shown

below is the detailed plan and sectional view of the SQUARE cut out required in every ALTERNATE

mid-landing slab in the Fire Escape Chute Duct. Slabs are required on only ALTERNATE Midlandings.

•The Cut out in the Slab will be a Square cut out of size 660 X 660 Void and a 75 mm deep step on

the upper side of Dimension 720X720 (as shown in the Drawing below) There should be no wall,

beam or any obstruction anywhere within a radius of 550 mm from the Centre of the Cut out.

The square aluminum alloy chute mounting frame of 700mm x 700m, is placed on to the cut square hole of the concrete floor or metal floor deck. The ring with chute fabrics is rested firmly on the round groove of the frame and it also served as an entry point to the chute.

Chute Segment The escape chutes of multi-entry system are divided into segments or sections in accordance to the number of storeys of the building, less the top storey. The highest storey does not have a chute segment. Each chute segment is rested firmly on to the round hole of the square aluminum frame at the floor inside the precinct/room. The lower end of each chute segment penetrates about 40/50 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.

Chute Fabrics The multi-entry escape chute installation consist 2 layers of chute fabrics: (A) Internal layer is made up of Aramid/Twaron fabric for resistant. This layer allows person smooth sliding inside chute and the friction is low enough that no serious injuries are caused. (B) External layer is made up of Spuncell elastic, for breaking the speed of descent. This is the braking layer, comparable to an elastic knee supporter that has braking power to arrest free fall, 'holds' the user as soon as the arms and legs are pressed against the chute. User can control own speed of descent by stretching hands and bending knees against this layer of chute fabric.




Entry Door to the Fire Chute Duct

•The entrance at each precinct is protected by a fire resistance door of at least a 60 Minute Fire

Rating. The minimum clear width of the door is 70cm and the height is 2m. The door is always closed

and locked under normal condition. The doors, if it open inward must never pass above the metal

ring of the chute frame (or within a radius of 550mm from the centre of the chute cut-out). In case

the Duct Size is the specified size of 1500x2500 then the door would need to open outwards. The

door for the ground floor is opened outward to ease the final escape. The doors must be fitted with

spring door closers. The doors must always be locked under normal circumstance to prevent

unauthorized access to the chute to prevent misuse, accidents, or sabotage.

•The Locks to the Doors must be integrated to the Fire Alarm System to facilitate automatic

unlocking of the doors when the Alarm is triggered.

A manual Call Point must be positioned next to each Fire Chute Entry Door, so that in an Emergency,

if the Fire Alarm has not triggered, then the Fire Alarm can be manually activated to not only sound

the Alarm but to also open the Fire Chute Door.

•The Door must have a Threshold at the bottom to minimise the entry of Water, Smoke, Dust and

Pests into the duct area. The door must also be provided with a smoke seal to prevent the entry of

smoke into the Duct. The Doors must also be provided with a Spring Door Closer to ensure that the

door is never left open when not in use during an emergency.

The Entire Duct will be maintained at a Positive Pressure to prevent the ingress of smoke into the

Duct. A suitable system will need to be designed with proper ducting routing and Pressure Fan

systems.

Electrical Engineering Requirements

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 systems will auto-start up the

various devices for ease of the evacuation process.

•The Locking/Unlocking System for the Doors will be linked to the BMS or Fire Alarm systems to

automatically unlock the doors in case of an emergency. The Locking Arrangement will consist of the

Electro-Magnetic and Plate Type Access Control Locking System which consumes approximately 50W

per Lock. These locks will normally be in an Energised condition which will keep the doors locked. In

an Emergency Situation when the Fire Alarm is activated, the Power to these doors will be

AUTOMATICALLY CUT OFF and the Doors will become openable. Each Entry Door will need a

230VAC/50W Power Plug Point near the Upper Side of the Door Frame which would be controlled by

the Fire Alarm System as mentioned above. The supply to this Electrical Lock must be from the DG

Backup Supply to ensure that the doors are not unlocked in a normal power failure.




•A manual Call Point must be positioned next to each Fire Chute Entry Door, so that in an

Emergency, if the Fire Alarm has not triggered, then the Fire Alarm can be manually activated to not

only sound the Alarm but to also open the Fire Chute Door.

•There will be an additional 230VAC/50W Plug Point and Switch will automatically be Switched ON

when the Fire Alarm is triggered. This Plug Point will be used to operate an Audio Instruction Box

during emergency situations.

•The Entire Duct will be maintained at a Positive Pressure to prevent the ingress of smoke into the

Duct. The Electrical Supply for the Pressure Fans will be supplied by the Emergency Supply. The Fans

will come ON Automatically when the Fire Alarm System is triggered. In case individual 18 inch

Pressure Fans are used at each level, then the Power Requirements will be approximately 300Watts

per Fan.

•There will be a 4ft (28W) Tube Light within the duct at each platform which will come on

Automatically with the Pressure Fans. Care must be taken to position the Tube light in a position

where it would not interfere with the chute movement.

•The Switching ON of the Pressure Fans and Tube lights at each Fire Chute Slab will also be

controlled by the BMS or the Fire Alarm System. These will be switched ON automatically when the

Fire Alarm is triggered in an Emergency. The Electric Supply to the Pressure Fans and Lights must

come from the Emergency Power Supply with Inverter or DG backup.

•There will be an Emergency Light mounted within the duct with a backup of time of Minimum 120

minutes. A 5/15 Amp Plug Point shall be provided in each chute room for this purpose. This point will

also be used for Maintenance and Servicing. This point can be supplied from regular power.

•There will also be Emergency Exit Signs and Emergency Passage Lights on each floor to provide

illumination during night time emergencies.

•There will be an Intercom or PA system at Each floor to provide guidance and to control the

evacuation from the control room during an Emergency situation.

Other Requirements

•2 Nos Smoke Masks will be placed at each Chute Entry Room to help in evacuating residents from

smoke logged areas.

•Baby Slings (on Floors where there are young children) will be placed in the Chute Room to enable

young babies/children to be carried by their parents while using the chute

•Fire Blankets may be kept in the Chute Room to help in evacuating Residents from Fire Locked

Areas.

•A small wall mounted Shelf (250 X 450) will be required within the Chute Room for storing the

above items.

• Photo-Luminiscent Signage/Evacuation Guidance/Direction Signage

Safety Considerations Review Currently, there is no industrial standard for the design, construction and installation of escape chutes in meeting specific performance requirements. However, Mobiltex Evacuation Systems has developed its own standards and requirements for the construction and the installation of the chute to meet its minimum requirement. All materials used for the construction of the chute comply with EC standard. Every Ingström Escape Chute installation is designed to meet stringent requirements for safety, strength and reliability for aiding emergency egress, and has given substantive consideration to User safety, taking into account the emergency situations in which it would be utilized. But nonetheless, buyers and suppliers should also do a hazard analysis and risk assessment of the intent use or the role of the Escape Chute in their overall building evacuation plan that they are considering. Like in all fire protection equipment, Escape Chute system shall be in good working conditions and ever ready for use virtually throughout its life; periodic maintenance to ensure proper storage of chute and its ready conditions for use at any moment is extremely important. Fire drills are supposed to prevent the Titanic effect-chaos in the event of a mass evacuation. The use of Escape Chute system should be used in accordance with the building evacuation plan, including users training and fire drill activities. As in all evacuation plans, first responders, building managers and even tenants would need to be trained and drilled in how to use the evacuation chute safely to ensure that the last great barrier to egress is overcome for all. After building occupants are familiar with the use of the Escape Chute, it becomes as effective as any other facilities used for aiding evacuation. With frequent practice in drills, people’s fear of entrapment is reduced when they know there is an alternative way out. The information contained in this document does not purport to address all of the safety concerns, if any, associated with its application/use. It is the responsibility of the buyer/user of the information to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Special considerations and potential significant hazards to specific Users of Escape Chute or adverse weather conditions that might be encountered that might affect the usability of the Escape Chute system in a safe manner that do not pertain to the design, construction and installation, if any

Warranty and After Sales Service Product warranty from manufacturer defects of 18 months from shipment and includes replacement of damaged parts on what the factory (Mobiltex Evacuation Systems) supplied in accordance to EC norm. The warranty period shall be reduced to 18 months from the date of testing & commissioning when Buyer did not take up the yearly maintenance agreement. The warranty period can be extended for up to ten years by entering a yearly maintenance agreement.
