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



11/44


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



12/44


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



13/44


SYSTEM

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.



14/44


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



15/44


SYSTEM

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:

Hazard Specifications:
