This document discusses smoke control and management systems. It defines smoke control as using mechanical systems like fans to limit smoke movement, while smoke management uses passive and active systems. The goals are to control smoke movement and create a tenable environment for occupants during a fire. Common smoke control methods are containment, removal, and opposed airflow using pressure differentials and airflow direction. Smoke control systems must interface and coordinate with fire protection, HVAC and other building systems. They require acceptance testing after installation and annual retesting to ensure proper function.

CPD Presentation: General Principles of Smoke ControlColt UK
Overview of the history of Smoke Control.
Legislation and the use of smoke control in the construction industry, including basic principles and guidelines for the main applications, including:
Single Storey Buildings
Shopping Centres
Atria
Fire fighting shafts
Apartment buildings
Car Parks
An explanation of the basic legislative requirements and how these are achieved using impulse ventilation
Application of impulse ventilation, both for carbon monoxide and for smoke clearance or smoke control
The advantages of impulse ventilation over traditional ducted extract systems
Use of CFD
Control systems used: carbon monoxide and heat detection systems
How impulse ventilation can be used to control smoke movement, allowing smoke control to be used, as part of a fire strategy, to compensate for the relaxation of other legislative requirements, e.g. travel distances
A case history of a particular project where travel distances were relaxed using impulse ventilation designed for smoke control
An explanation of how this project was validated using CFD and live fire tests
The design of relief/venting systems is imperative in facilities because existing installations or other design requirements frequently result in the potential for atmospheric releases. To ensure atmospheric discharges are to a safe location as required by good engineering practice [e.g. ASME Section VIII UG-135 (f)], facilities should consider the qualitative requirements, decision making processes, and quantitative methods summarized in this paper.
This paper can be used as the basis for analyzing new and existing facilities. The first section of this paper details qualitative considerations to ensure that the discharge location is safe. The following sections provide quantitative and semi-quantitative means to verify that the concentration of flammables and toxic material is within specified limits. The final portion of this paper contains information typically required to perform dispersion modeling. The purpose of this paper is to simplify existing methods, such that typical plant engineers with everyday tools can screen most atmospheric releases.
Detailed dispersion modeling was performed to validate the results of the simplified equations presented in this paper. Under the most common conditions that hydrocarbon streams are processed, the methods in this paper are conservative and can be used to screen atmospheric relief device installations.
Smoke evacuation in industrial buildingZuhal Şimşek
Smoke occurs as a result of solid and liquid particles carried in the air from the burning of materials created
from the combustion of gases. A dark colored smoke screen is formed. It may be toxic and explosive which make
evacuation and responding to the fire more difficult. All these problems can be overcome with an appropriate
smoke evacuation system. Smoke evacuation systems can be divided into two categories as natural and
mechanical systems. However, they can vary according to needs, the people intensity; materials found in the
structure and area, architectural features and design standards. The modelling based on the scenario planned for
the most appropriate smoke evacuation system was carried out in compliance with international standards and
local regulations. In this study, a vehicle part warehouse belonging to the Oyak Renault automobile factory was
established inexactly the same way as the original. Using the CDF based PHONEICS system it was designed that
a fire broke out in the warehouse and in the design, parking lot fire data were taken into consideration as given
in British Standard (BS) standards ‘Components for smoke and heat control systems’ section 7. Vehicle parts
found in the warehouse were in parallel with vehicles which had installation completed in the parking lot without
a sprinkler. The smoke emerging as a result of the fire, which had an area of 5×5 m2 and 8MW magnitude and
broke out in the warehouse (without sprinkler) whose area and volume were 4680m2 and 37206m3 respectively,
was tested with 6 smoke evacuation fans activated at the beginning of the fire. The Total Fan capacity was
designed as 10 volume/hour and 15 volume/hour, evaluated according to the maximum CO amount, vision and
temperature by simulation for both situations. As a result of the tests performed, ideal visibility

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

2. Objectives
‣Define the terms smoke control and smoke management.
‣State the design goals for smoke control systems.
‣State the design goals for smoke management systems.
‣Name the three general methods used to control smoke
movement.
3. Objectives
‣Describe the four pressure differential methods used to control
smoke.
‣Describe five design requirements or operational characteristics
of smoke control systems.
4. Objectives
‣List the different life safety and fire protection systems that
interface with smoke control systems and describe how they
interact.
‣Discuss the importance of the acceptance testing and annual
retesting of smoke control and management systems.
5. Introduction
‣Smoke and toxic gases migrate outside the fire area and
throughout a structure during a fire.
‣Can cause as much damage as burns
‣Exposed areas: stairways, corridors, elevator hoistways,
atriums, openings in walls, etc.
6. Introduction
‣Smoke control: mechanical systems that pressurize areas of
buildings with fans to limit smoke movement
‣Smoke management: passive and active systems used alone or
together to alter smoke movement
‣Life safety objective of systems is to create a tenable
environment for occupants and fire fighters; systems were
developed in the 1970s.
8. Introduction
•Active design approach
–Focus of this chapter
–Uses mechanical systems to exhaust, pressurize, and oppose
smoke with forced air
•Choice of design (passive, active, combination) depends on
many factors.
9. Introduction
‣Physical design and architectural features of structures facilitate
smoke movement.
‣Obvious: stairways, elevators, airshafts, ductwork
‣Less obvious: unsealed construction and space, etc.
‣Smoke spread also depends on many factors.
‣Buoyancy forces, stack effect, climate, ventilation and HVAC,
fuel load, etc.
10. Code-Required Smoke Control and Smoke
Management
‣Code-mandated installation is limited to certain kinds of
structures and occupancy classifications.
‣Design of many buildings facilitates quick evacuation, inhibits
smoke movement, and includes fire protection systems.
‣Smoke control systems are required for high-rises, atriums,
covered malls, underground buildings, stages, platforms,
correctional facilities, etc.
11. Smoke Containment, Removal, and
Opposed Airflow
‣Goal is to maintain tenability by mitigating smoke spread or
containing it.
‣Systems can be stand-alone or integrated.
‣100% outside air for positive pressurization and smoke relief
systems; 100% exhaust to the outdoors to contain/relieve
smoke
‣Methods: containment, removal, opposed airflow
12. Smoke Containment, Removal, and
Opposed Airflow
‣Containment by pressure differentials
‣Pressure differentials between affected and unaffected areas
help with smoke control.
‣Low pressure differentials reduce/contain smoke.
‣Pressurization is one of the most common methods of
smoke control.
‣Model building codes, standards, and publications outline
design requirements (NFPA 92, 92A, 92B, and publications
from ASHRAE).
14. Smoke Containment, Removal, and
Opposed Airflow
‣Stairway pressurization systems (cont’d)
‣Perform best when combined with smoke removal/relief on
affected floors
‣Many design considerations affect performance.
‣Common in high-rise buildings
16. Smoke Containment, Removal, and
Opposed Airflow
‣Floating zone/floor-by-floor pressurization (cont’d)
‣Used in high-rises in addition to stairway systems
‣Smoke-laden air is removed; outside air flows in.
‣Air moves from high to low pressure.
‣Negative pressurization uses mechanical fans to remove the
smoke from the zone or floor through an exhaust shaft.
17. Smoke Containment, Removal, and
Opposed Airflow
‣Elevator hoistway pressurization systems
‣Similar to stairway systems
‣Mechanical fans pump outside air into hoistway and create a
pressure barrier to smoke.
‣Some designers think they should be part of complete smoke
management system for adequate pressurization.
‣Others are concerned about elevator doors being open.
‣Movement could cause drastic changes in the hoistway
pressure
19. Smoke Containment, Removal, and
Opposed Airflow
‣Refuge areas
‣Constructed with fire-rated materials and self-closing fire-
rated doors
‣Holding areas for people who need assistance
‣Typically combined with elevator hoistway or stairway
pressurization
20. Smoke Containment, Removal, and
Opposed Airflow
‣Smoke removal
‣Best suited for large volume spaces where smoke and toxic
gas flow freely
‣Systems can help create a tenable environment in egress
corridors, elevator lobbies, and refuge areas.
‣Lack of restriction causes other problems in addition to large
amounts of smoke and gas (e.g., delayed activation of
sprinklers and detectors).
22. Smoke Containment, Removal, and
Opposed Airflow
‣Containment by airflow direction
‣Can control smoke across openings when pressure
differential strategies are impractical
‣Common for fires in railway, subway, or vehicle tunnels
‣Least common strategy for containment because of the
complex control and necessary large air volumes
‣Risk of feeding the fire
23. Design Requirements and Operational
Characteristics
‣Design is challenging due to the uniqueness of environments.
‣Important to know the requirements of adopted model codes
and standards
‣Model codes include a variety of operational requirements.
24. Fire Protection Systems and Smoke Control
‣Without automatic or manual detection and suppression, smoke
control systems may be overwhelmed by fire.
‣Proper operation of detection and automatic sprinkler systems,
plus fire fighter response, is key to controlling smoke and gas.
25. Fire Protection Systems and Smoke Control
‣Interface with fire protection systems and other life safety
systems
‣Smoke control and management systems interface with fire
protection, HVAC, elevator, and backup power systems.
‣During design, smoke control zones, sprinkler zones, and
detection zones are coordinated.
‣Activation of automatic initiating device usually prompts
operation of smoke control systems.
26. Fire Protection Systems and Smoke Control
‣Interface with fire protection systems and other life safety
systems (cont’d)
‣If HVAC systems fail to shut down, this can be the strongest
contributor to smoke movement (usually coordinate well with
other systems).
‣Smoke detectors in elevator lobbies interface with elevator
systems to establish recall priorities.
‣Smoke control systems require both normal and emergency
power sources.
27. Fire Protection Systems and Smoke Control
‣Interface with fire protection systems and other life safety
systems (cont’d)
‣Functional components of smoke control systems require
monitoring.
‣Must have operational controls for each smoke zone
29. Testing and Performance Verification
‣Acceptance testing
‣Design professionals develop detailed test plans.
‣Testing occurs after all other life safety and fire protection
systems are tested and approved.
‣Testing is similar to other fire protection systems’ tests.
30. Testing and Performance Verification
‣Acceptance testing (cont’d)
‣Functional and integrated performance testing:
‣System response time
‣Air pressure differential
‣Door opening forces
‣Artificial smoke/fog can give visual confirmation of
performance but is not an actual representation.
‣All final tests must be witnessed and documented.
31. Testing and Performance Verification
‣Acceptance testing (cont’d)
‣Smoke control systems must undergo annual functional and
performance retesting to avoid disrepair.
‣Required by many state and local jurisdictions
‣Addresses individual components and integrated
performance
‣Similar procedures to acceptance testing
‣Some tests performed by owner’s personnel, some by
individuals who did initial testing
‣Annual testing
‣Systems should undergo annual functional and performance
testing.
‣Without this, systems can rapidly fall into disrepair or
failure.
