INTRODUCTION |
| |
1. |
Fire starts without
warning and can cause wide-spread damage. A little preventive cost and proper planning
can help reduce this damage. |
2. |
Fires can be fought on two
fronts: first, by preventive measures and second,
by fire-fighting equipments. |
3. |
One of the preventive measures
is the use of fire Doors in buildings and
others are use of fire resistant Coatings. |
|
| |
These doors perform three important
functions as follows:- |
| |
1. |
They isolate the area of
origin of fire by creating and maintaining separate
enclosed areas.This is known as
‘Compartmentation'. |
2. |
They allow controlled unhindered
‘Passage of people and goods' between compartments of a building on fire. |
3. |
They allow “Smoke – free” access
to the escape routes, both horizontally and vertically, and protect corridors and shafts. |
|
| |
Fire doors also satisfy the legal
requirements laid down by the National Building Code on
Fire Safety (part IV) and the code of practice for fire
safety IS:1642. These require the use of fire doors of
specified resistance-30 minutes to 4 hours –in high rise
buildings, apartments, hotels, hospitals, industrial
buildings, etc, for ‘Compartmentation' to limit the
potential loss to provide ‘personnel safety' by allowing
easy escape to people in a building on fire.
These doors of specified rating are
required to be fixed at doorways, lift shafts, hoists,
shafts, conveyors and other critical openings.
The use of fire doors is mandatory as
per Delhi Fire Safety Act 1986. |

|
TECHNICAL SPECIFICATIONS |
| |
Fire-resistance in a fire door is expressed in terms
of minutes and is required to satisfy the following
performance criteria:- |
Stability :- The Fire
Door shall not collapse during the rated period of
resistance under the specified fire conditions. |
Integrity:- The fire
doors shall not allow the passage of hot gases or flames
through the rabbet or the gap between the doors frame
and shutters or through any damage developed in the
shutter during fire. Smoke escaping from the door on a
lower floor of a building on fire could seriously affect
the escape of people trapped on the upper
floors. |
| Insulation:-The
mean temperature of a fire Door, on its unexposed side,
shall not exceed 163 degree C above ambient. Lower
temperature ensures quick escape of people and prevents
combustion of flammable goods lying on the side
unexposed to fire. |
|
| |
Fire doors are governed by the following
specifications:- |
| |
| • BS 476 part 8:-
Fire Test on Building Materials and structures. |
| • ISO 834:- Fire Resistance
Test on Elements of Building Construction. |
| • ISO 3008:- Fire Resistance
Test on doors and Shutter Assemblies. |
| • ISO 3809:- Fire Resistance
Test on Structures. |

AROMA STEEL FIRE
DOORS:AK-204
Aroma Steel Composite fire doors AK-204
is manufactured of 18G M.S. sheet/GI sheet coated with
fire resistant coating AK-525 on both the faces and is
filled with Fire Resistant filler to achieve a thickness
of 60mm for 2 hours fire rating and 80 mm for 4 hours
fire rating. |
AROMA WOODEN FIRE
DOORS AK-207
Aroma Wooden fire door is manufactured
from wooden sheet 12mm thick on both sides coated with
fire resistant coating or laminates and filled with fire
resistant filler to provide 50mm thickness for one hour
fire rating. Door frame is manufactured out of hard
wood/ teak wood treated with fire resistant compound. |

SPECIAL FEATURES OF AROMA
FIRE DOORS |
| |
1. |
Available in single shutter, double
shutter, single swing, double swing and
sliding Configuration. |
2. |
Aroma Fire Check doors
are manufactured using special techniques employing high
grade tested materials,
heat activated sealing Compound, fire-resistant
compounds and
surface coatings to achieve
“Total Protection”, both from horizontal and vertical
fire conditions, unmatched
by any manufacturer. |
| 3. |
Aroma fire Check doors
are lighter in weight.. |
| 4. |
Internationally, the use of asbestos is banned in the
construction of fire doors due to the
extremely harmful toxic gases
generated when asbestos is subjected to fire. Aroma fire
Check doors are completely
asbestos free. |
| 5. |
Aroma
fire Check doors consist of properly designed door
frames of Steel or Galvanised
Iron in case of steel doors and seasoned hardwood
or Teak wood in case of wooden
Fire check Doors conforming to IS:1141. The fire
–resistance is further enhanced
by the application of a special Fire- resistant coating. |
| 6. |
Test experience has shown that the
use of a heat- activated sealing Compound is a must
even to achieve a 30 minute fire
rating . Under fire conditions, such a heat –activated
intumescent ( swelling up() seal
provides a positive pressure in the gaps between the
frame & the shutters. This
helps eliminate any distortion which can lead to
‘Integrity Failure' of
the door.
Aroma fire doors incorporate proven
intumescent sealing Compound which has been tested under
severe fire conditions in all types of situations.
During fires, the heat-activated
sealing Compound provided in the door assembly, and its
design, play a very important role. Therefore, it is
essential to install the full fire door set comprising
of the door frames and the shutters. If only shutters
are procured from us the performance may be compromised.
However, where door frames have already been fixed the
dimensions, specifications and a sketch of the door
frame must be sent to us to assess its suitability for
incorporation of a heat-activated sealing compound and
for its other fire performance criteria. |
| 7. |
Aroma Wooden fire doors are normally
of flush type with 4mm teak or commercial
plywood facing bonded with
non-flammable, fire-retardant adhesives. |
| 8. |
Aroma fire doors are ready to
install, fully ‘painted' or ‘polished' in pleasant
shades of the customer's choice using
special fire-resistant coatings. The “paint”or ‘polish'
finish so provided is Acid-, Alkali-,
Weather- and stain resistant and extremely durable
providing twice the life as compared
to conventional enamel paints or spirit/shellac polish. |
| 9. |
It is desirable that fire doors
installed on an escape routes to allow easy escape route
should not be
“secured”. This will avoid possible delay in opening it
by people trapped in the
building. |
| 10. |
In high rise buildings,
the fire doors should open outwards towards the escape
Routes to allow easy
escape. In such a case, to maintain compartmentation.
Aroma fire doors are
provided with self-closing devices. |
| 11. |
Great care should be taken in the
installation of a fire door so that the gaps between the
frame and the shutters are
kept uniform and within specified parameters. The
company can install
these doors for you or, if you prefer, you can install
them yourself with the
instructions provided. |
| 12. |
Aroma fire doors are factory-treated to resist attack from termites & insects. These doors are sturdy & hardly require any maintenance.You can further improve their performance:- |
| |
| • |
By periodically checking to see that the intumescent sealing Compound in the gap between the door shutters and the door frame is maintained. Vandalism and accidental damage can affect the performance of the sealing compound. This can be repaired or replaced by contacting us at the earliest. |
| • |
By periodic maintenance to retain the aesthetic appearance of the doors. This should be carried out using only Aroma Fire-Resistant Coatings which help retain class I spread of flame properties. |
|
| 13. |
Upgrading the fire rating of existing solid core flush Doors is possible:- |
| |
| • |
by using Aroma Fire- resistant coatings; |
| • |
by providing Aroma Heat-Activated Sealing Compound on door frames and shutters; |
| • |
by redesigning the hardware on doors. |
|

available from the company. Please include the
specifications and a dimensioned drawing of the door
frame, shutters and related hardware with your request.
