DESIGN AND INSTALLATION OF FIRE SUPPRESSION SYSTEM
3. INTRODUCTION
Fire suppression system is an engineer system that sharply reduces the heat
ratio of fire and preventing its re-growth by means of direct and sufficient
spraying of water through the fire plume to the burning fuel surface.
Fire suppression system is an active system that comprises of the following
system: Automatic sprinkler system, Stand pipe system, clean agent fire
suppression system, Portable fire extinguisher. In safety Consultants and
Solutions Provider, i was opportune to be directly involved in the design and
installation of the following fire detection and fire suppression system
project.
Design and installation of fire detection, alarm and suppression
systems as per NFPA 409 for LLOYDs accreditation for evergreen
apple hanger, the largest hangar for servicing BOEING aircrafts in
West Africa. Systems system include foam, sprinkler, FM-200,
hydrant and hose reel.

3.2 DESIGN OF A DETECTION, ALARM AND SUPPRESSION
SYSTEMS AS PER NFPA 409 FOR LLOYDS ACCREDITATION
FOR EVERGREEN APPLE AIRCRAFT
3.2.1 PROJECT DESCRIPTION
The Hangar is purpose built facility located in the service zone on the airside at the
MMA International Airport. The premise is a middle plot bounded by accessible
motor Road to the front, airside to the back, Aero Contractors Hangars to the left
side and empty plot of land the right. It is protected by high walls to the front and
right side.
The facility is a 4-storey structure, with three office wings to the front, left and
right. The main aircraft hangar measures 2170.8m2 and is centrally to the back of
the front offices and between the left and right wings. Two helicopter service areas
measuring a total height of 11m, occupy the first two floors of the right officewing. Located at the top is a pent-house used for a bar/restaurant.
It is estimated that the office space can accommodate an occupancy loading of
100-200 upon completion.

SYSTEM
Aircraft hangars present peculiar hazard with respect to evacuation in the case of a
fire scenario. This is so because of the weight and limited mobility of the vessels
thus reducing rapid evacuation. The design of this hangar building and fire safety
components recognizes the need to minimize the possibility for a full-scale
evacuation requiring removal of aircrafts. The construction type also takes into
cognisance risk of collapse in case a fire. The compartment integrity included
prevents the ingress of smoke and spread of fire to other areas. Horizontal
evacuation of aircrafts combined with defend-in-place philosophy similar to that of
hospitals has been greatly preferred in the designs. .
3.2.2 FIRE SYSTEM DESIGN AND INSTALATION
Design and installation of fire system services at the evergreen hanger covers
design, installation of both Mechanical and Electrical system, this project posed a
great challenge on my career owing to the complexities of the design of this
system.
As design Engineer, I was saddle with the responsibility of providing a consultancy
service that will meet the globally acceptable fire safety standard such as NFPA to
meet Lloyd certification. The basic fundamental approach to fire and life safety
design include the following.
Construction type classification
Occupancy classification.
Active fire system
Passive fire system

SYSTEM
(a) CONSTRUCTION TYPE CLASSIFICATTION
First the layout, construction type, and architectural design concept was vetted for
compliance and adequate consideration of the defend-in-place theory. This
follows the total concept that hangars shall be designed, constructed, maintained,
and operated to minimize the possibility of a fire emergency requiring the
evacuation. SCSP findings proved that this criterion was met in the certified
design drawings based on TYPE 1 442 Fire Resistive construction. This ensures
structural integrity and appropriate resistance in case of a fire.
(b) OCCUPANCY CLASSIFICATION
The hanger was classified as Extra hazard occupancy (group two) based on the fact
that combustibility of its content is very high, dust, combustible and flammable
liquid present. There is rapid developing of fire with high rate of heat release, the
classification serves as the bases for the whole design and was based on NFPA 101
Life and fire safety Code
(c) ACTIVE FIRE SYSTEM
This are the fire suppression system and are key to the success of the overall
protection scheme, it is a build safety plan that are incorporated in the building,
that prevent the spreading of fire within the building and also perfect the
emergency escape procedure. The active fire system was design for the hanger
based on these criteria
Compartmentation
Means of egress

SYSTEM
Building management system
COMPARTMENTATION
Buildings are designed to prevent fire, heat, and smoke from spreading beyond
locations of origination. Building elements such as fire walls, fire dampers, and fire
doors, are designed to seal off one location from the next. This system is called
compartmentalization. Compartmentalization increases the safety of evacuating
building occupants because smoke and fire are not able to escape into exit passage
ways. It was based on this bases that the a two hours fire rated door and wall was
design for each enclosure was designed
MEANS OF EGRESS
Unobstructed and adequately marked means of egress was design to ensure safe
emergency evacuation Exit doors the office door and hanger was design on the
bases that they can readily opened from the egress side whenever the building is
occupied. Locks, if provided, shall not require the use of a key, tool, or special
knowledge or effort for operation from the inside of the building, unless permitted
by NFPA 101 Life Safety Code Exit signs and Emergency lighting illumination
levels was design in accordance with the Life Safety Code. Safety and escape route
lighting is required to assist staff in the safe movement of patients and visitors to
alternative locations and to support a full evacuation in the event of an emergency.The levels of illumination should be sufficient to allow the process of progressive
horizontal evacuation, especially again on the 2nd floor where bed-ridden patients
are housed

BUILDING MANAGEMENT SYSTEM
An efficient building management system which is a computer based control
system was incorporated in the building system to control and monitor the
building mechanical and electrical equipment such as ventilation, lighting ,power
system and fire and security system. The provision of a two-way voice
communication, PABX and general alarm system is incorporated in the design to
facilitate early and orderly evacuation in the event of a fire. All compartments and
exit parts are equipped with these devices manned centrally from a FCC.
(c) THE ACTIVE FIRE SYSTEM
The design was primarily based on passive protection methodologies in the
prevention of fire hazards or the mitigation of its consequences,But on the fact that
active fire system play a significant role by minimizing the impact of potential fire
on occupants and valuable properties, However, additional layers of protection
have been employed to provide a more robust and resilient system of safety by
complementing these passive strategies with active protection systems.
It was based on this criteria that the maintenance hangar for Evergreen Apple
Nigeria Ltd was designed based on NFPA 101 to include integrated active system
for fire protection and life safety that incorporates alarm and detection systems to
provide early detection/ warning of emergency as well as fire suppression system
which include manual and automated systems for the extinguishment of fire at
incipient stage as depicted in the certified drawings.
The alarm and detection systems are designed as per NFPA 72/ BS 5839 whilst the
sprinkler and foam systems are designed in compliance with NFPA 13/16 and
satisfy the requirement of NFPA 101 and 409.

POST GRADUATE EXPERIENCE IN DESIGN ANDINSTALLATION OF FIRE DETECTION AND SUPPRESSION
SYSTEM
Sprinkler coverage has been provided for the entire hangar floors of the Service
Areas.
Hose reel and portable extinguishers of appropriate types and sizes are strategically
located around the building to provide rapid knockdown of incipient fires when the
need arises. The hangar building has a combination of systems to detect fires, warn
occupants, and automatically and manually aid fire control and extinguishment. A
special mandate to the fire alarm requirements for hangars demands the installation
of automated systems to actuate and suppress the fire during un-manned hours.
3.2.3 FIRE ALARM & DETECTION
In accordance with NFPA 72, C-TEC Conventional Systems that automatically
provides a general alarm, perform all the control functions the device requires and
sound an alarm alerting all present was designed for the offices. The central panel,
with 16 zones, is visibly located in the lobby area on the Ground floor and has a
back-up battery for continuous availability in case of a power failure. This system
is design. For proper systems management and servicing; an operational check list
and maintenance plan is being developed to ensure reliability and availability in
the future.
The detectors are distributed throughout the office space and ceiling voids ensuring
that they fall within the maximum spacing range. Quantities of detectors required
are dependent on room size. For the main hangar area, detectors are tied to a
suppression panel and can both alert and activate the foam monitor system that is
divided into 4 zones (two within the main hangar and one in each helicopter
service area. Manual call points, sounders and bells electrically connected to the

central panel are located at each emergency exit. The wiring used for the electrical
connection is 1.5 mm fire rated cabling channel through PVC pipes mostly run in
the ceiling voids.
3.2.4 FIRE SUPPRESSION SYSTEMS
For suppression, the following fire suppression system was designed
External Hydrant System
Hose Reel System
Automated Closed Head Sprinkler System
Low-Level, Low-expansion Foam Monitor System
Portable extinguishing System
3.2.4.1 SPRINKLER & LOW LEVEL LOW EXPANSION FOAM
The designed was based on TheNFPA 409 mandates the installation of a closed
head wet automatic sprinkler protection system in Group I hangars. For this
project, has been adequately designed following NFPA 13. Listed quick response
sprinklers are installed throughout the main aircraft hangar and the helicopter
service areas.
A supplementary foam monitor system have been designed for the main and
helicopter service areas though the vessels handled here and UN-FUELED.
Because these two systems represent the main protection systems within the
Evergreen Hangar, below is the design basis:
