What the Draft Building Safety Bill Will Mean for Service and Maintenance of High-risk Buildings

Posted by Conor Logan on 25/09/20 10:15

Last month I wrote a technical review of the latest Fire Safety Bill, where I outlined the specific details of how the Fire Safety Bill legislation will be implemented and enforced.

Corridor ventilation: smoke and temperature control

Posted by Conor Logan on 03/09/20 14:00

When it comes to corridor ventilation, two things must be taken into consideration: effective smoke evacuation in the event of a fire and preventing overheating, for day-to-day comfort ventilation.

The impact of door size on smoke control design

Posted by Conor Logan on 24/06/20 10:00

One of the biggest challenges in the design of smoke control and pressurisation systems currently is the relatively recent trend towards installing full height doors which extend all the way to the underside of the ceiling, and/or very wide single leaf doors.

7 reasons why you shouldn't use HVAC control systems for smoke ventilation

Posted by Conor Logan on 02/06/20 10:00

Smoke ventilation systems today require sophisticated control systems with highly complex sequences of operation. HVAC control systems could be seen as a viable solution, as they can be extremely flexible and offer a high degree of programmability. However, while they may be adequate for simple applications, there are a number of issues that mean they do not deliver on all the functionalities needed for more complex schemes.

Here are 7 reasons why:

BCO lecture on smoke control in high-rise residential buildings.

Posted by Conor Logan on 06/05/20 10:00

Smoke control in high-rise residential buildings is an important and, sadly, topical issue. Having recently written a post about the talk that I gave to the Institute of Mechanical Engineers on smoke control in general, I now want to focus on high-rise residential buildings , a subject that I also addressed with the engineers and, in particular, in the talk I gave to Northern Ireland Building Control Officers in Armagh.

IMechE lecture on clarifying the importance of Smoke Control

Posted by Conor Logan on 22/04/20 10:00

I recently, before the Corona virus lock-down, had the pleasure and privilege of giving two lectures on smoke control, one to the Institute of Mechanical Engineers and the other to Northern Ireland Building Control Officers in Armagh. For this second audience I focused in particular on smoke control in high-rise residential buildings.

Technical Review of Approved Document B (Fire Safety)

Posted by Conor Logan on 17/04/20 10:00

On the 2nd April, Housing Secretary Robert Jenrick MP announced ambitious steps, initiated by the aftermath of the Grenfell Tower fire, to further reform the building safety system, with the aim of ensuring that residents are safe in their homes.

Firstly, MHCLG have published their response to the Building a Safer Future Consultation which sets out plans to reform building safety. This includes creating a new, more stringent, national Building Safety Regulator, currently being devised by the Health and Safety Executive, who will be responsible for implementing, enforcing and overseeing safety in all multi-occupied residential buildings over 18m (or 6 storeys). Importantly, the Building Safety Bill will also provide for the ability to amend the scope in the future, if deemed justified.

No time to relax our vigilance

Posted by Conor Logan on 12/02/20 11:00

Despite the new regulations that have been introduced or proposed following the Grenfell tragedy in 2017, this is not the time to be complacent about fire. The latest available statistics on fire in England showed that fires actually increased in the year to March 2019. In the 10 years to 2012/13 there had been a steady drop in fires every year, but since then the figure has been slowly creeping up again.

Specifying, testing and commissioning smoke control systems – your ultimate guide.

Posted by Conor Logan on 05/11/19 14:00

Smoke control is a ‘wide science’: it requires in-depth knowledge of the building layout, the technical aspects and the bewildering array of regulations in force. Each type of building has its own peculiarities and some have specific regulations and guidance on smoke control.

How to deal with engine exhaust emissions when local exhaust ventilation is not an option

Posted by Paul Langford on 10/10/19 10:00

Problem

Controlling diesel engine exhaust emissions in enclosed spaces such as maintenance workshops is easily done with local exhaust ventilation (LEV), which can be as simple as fitting pipes to the vehicles’ exhausts while they are being serviced in order to draw the fumes outside. However, there are situations where this is not an option, for example in a warehouse where there is heavy vehicle movement inside the building, as vans and lorries come in and out for loading and unloading.

Preparing car parks for the risks of charging electric vehicles

Posted by Conor Logan on 04/10/19 10:00

Car parks may experience a new risk with the growing prevalence of electric cars and, in particular, the likelihood that the cars will be charged in car parks. This may lead to a number of fires in their lithium ion batteries, that will pose a challenge to firefighters and to those responsible for safety in the car parks.

Smoke control system design and installation. Common mistakes and why it is vital to avoid them.

Posted by Conor Logan on 05/09/19 16:30

In my last blog post I wrote about the government’s proposed changes to the Building Regulations as they relate to fire and broadly welcomed them (the main concern is that the very sensible measures proposed for high-rise residential buildings should also be applied to their shorter cousins).

But principles are only as good as the way that they are applied, and in terms of fire protection, and of smoke protection in particular, the devil is certainly in the detail. If these systems are to work properly they have to be designed properly, installed properly and maintained properly. Sadly, this does not always happen.
