At our recent webinar with guest speaker, John Klote, we had a large attendance with many questions asked. Here you can find John's and my answers to these questions, slightly edited for clarity.

The main objective of this paper is to calculate the sterile area around an existing vertical flare of length 112 meters, located in an onshore facility and evaluate whether the current design is acceptable during a General Power Failure (GPF) scenario. The sterile area will be calculated at an elevation of 2m, which represents the typical head height for personnel.

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
The performance based approach involves the assessment of three basic components comprising the likely fire behaviour, heat transfer to the structure and the structural response. The overall complexity of the design depends on the assumptions and methods adopted to predict each of the three design components.
A flame arrester operates by removing heat from the flame as it attempts to travel through narrow passages with heat-conductive walls. The arrester will stop a high velocity flame by absorbing heat away from the flame head, which lowers the burning gas/air mixture below its auto-ignition temperature, and creating an atmosphere where the flame cannot be sustained. The channels or passages in the flame arrester are designed to very efficiently conduct heat outward, but still allow the gasses to flow.

Seven good practices for pressurisation systemsColt UK
As a designer or specifier, you want to be sure that your smoke ventilation system will provide fire safety in all situations. If your design includes a pressurisation system, there are a few pitfalls to avoid. Here are seven good practices that will help you avoid them and design an effective pressurisation system:
Can car park ventilation schemes be more energy efficient? Yes – and they sho...Colt UK
Why is energy efficiency not regulated in car parks?
The regulations applying to car parks do not specifically advocate the conservation of energy but surely they should do. It does not make sense that buildings are subject to energy efficiency and low carbon emission targets driven by regulations such as Approved Document L (ADL), while car parks have no such requirement.
CPD Presentation Evaporative cooling in data centresColt UK
Data centres that use evaporative cooling can cut their energy bills by up to 80% compared to conventional cooling methods!
The specifications for the environmental operating conditions of IT equipment used in data centres have recently been revised, opening the way to evaporative cooling in such buildings. Evaporative cooling can provide a highly effective solution, with low installation and running costs, minimal maintenance requirements and quiet operation.
This seminar covers:
• Revisions to the specifications for the environmental operating conditions of IT equipment in data centres
• Options for cooling in a data centre
• Implementing evaporative cooling in a data centre.
CPD Presentation - Smoke control and environmental ventilation in residential...Colt UK
Often corridors in apartment buildings suffer from persistent over-heating. The growth in popularity of district heating and hot water plant often leads to relatively high heat gains in common corridors, and this is exacerbated by the fact that buildings have higher levels of insulation. There are a number of solutions, ranging from natural or mechanical ventilation through to cooling. This Seminar focuses on the options available to developers and designers.
What you'll learn:
Design considerations relating to ventilation measures in residential corridors
Using smoke control systems as a dual purpose system to provide environmental ventilation – the options and limitations
Considerations regarding control systems.
Equipment specification
CPD Presentation: Key considerations when specifying weather louvresColt UK
The purpose of our presentation is to highlight areas of consideration for both Architects and Service Engineers to ensure that specifications adequately reflect design requirements and performance expectations.
Pressurisation Systems in residential and commercial buildings

You want to improve your factory’s productivity: what’s next?Colt UK
The direct links between a comfortable work environment and productivity have been clearly shown by many studies. How do you know if you have a problem and what can you do?
As a factory manager you may have noticed some fluctuations in your facility’s production quality or volumes, or a changing pattern in staff complaints. These could be the first warning signs that production is not running as smoothly as it could and that there may be room for improvement in your factory’s productivity.
Are you sure your natural ventilation system is really energy efficient?Colt UK
You are specifying an energy efficient ventilator: what do you focus on – ventilator U value or air leakage? The simple answer is that both are important and need to be considered together.
As a designer or specifier you will set U value requirements for elements of your building in order to meet Building Regulations, ensure comfort and avoid condensation.

Book Formatting: Quality Control Checks for DesignersConfidence Ago
This presentation was made to help designers who work in publishing houses or format books for printing ensure quality.
Quality control is vital to every industry. This is why every department in a company need create a method they use in ensuring quality. This, perhaps, will not only improve the quality of products and bring errors to the barest minimum, but take it to a near perfect finish.
It is beyond a moot point that a good book will somewhat be judged by its cover, but the content of the book remains king. No matter how beautiful the cover, if the quality of writing or presentation is off, that will be a reason for readers not to come back to the book or recommend it.
So, this presentation points designers to some important things that may be missed by an editor that they could eventually discover and call the attention of the editor.
