Fire - The External Risk

When we consider fire safety, our focus is normally from within, what can we do to prevent the occurrence of fire and how we can limit its damage. Whilst this is the correct stance to take, we must also identify and consider the risks from external sources.


Fire Precautions - Compartmentation

Fire compartmentation is a vital part of any fire safety design. Compartmentation is a tool that is used in the vast majority of buildings, other than simple low rise developments.


Unwanted Fire Signals

Unwanted Fire Signals is the formal term given to what has been universally referred to as 'false alarms'. Unwanted fire signals is considered to encompass the issue and this will become apparent as we expand on this issue.


Management of Fire Safety

As with most elements of Health & Safety, management of fire safety is fundamental to its success. Whilst fire precautions will play their role in any given situation, it is often the success, or failure of management that has the most significant impact on the outcome.


A managed response to a fire

Much technical data is available which discusses the risk of fire within buildings and the measures which are employed to prevent fires, reduce their growth and permit the safe evacuation for occupants, however, little formal guidance is available for building managers on responding to a fire.


Types of Fire precautions, their use as Compensation Features

Fire precautions are often categorised into two groups, active and passive. A fire safety design will rarely rely on only one or the other categories, usually a combination of fire precautions will be necessary to achieve a safe design.


Means of Escape Design

As designers of buildings, we must acknowledge that any fire safety design can fail, i.e. a fire could occur.


Human Behaviour in Fire

A major consideration in any fire safety design is human behaviour. Failure to consider this aspect could lead to a failure in the design.


Fire fighting hose reels

There is a growing trend for occupiers to remove the existing fire-fighting hose-reels from their premises. This is due to a number of factors:


Fire Safety on Construction Sites

Fire Safety / Fire Engineering is used to protect buildings and their occupants from fire. However, fire safety and the protection of people and buildings should start before the construction phase, an area that is sometimes overlooked.

FIRE SAFETY BLOGS

  • Facilities Management & Fire Safety - Gaseous Systems - Part 21

    In this blog series for those who work in Facilities Management and who have an interest in or responsibility for fire safety, LWF has been looking at the different types of fixed fire-fighting systems. Such systems are placed in a building, or specific areas of a building, and might appear largely dormant (aside from appropriate maintenance and testing) until a fire is detected. The most commonly used fixed fire-fighting system is probably a sprinkler system,...

  • Fire Engineering Design and Risk Assessment - Fire Suppression & Sprinklers - Part 8

    In this Fire Engineering Design and Risk Assessment blog series for Architects and others in the building design business, LWF has been looking at the various advantages of sprinklers as part of a building’s fire protection arsenal.  In Part 7, we looked at the concessions that may be made in cases where sprinklers are present. In Part 8, we discuss how an understanding of the ways sprinklers can be used as per the prescriptive...

  • Fire Engineering Design and Risk Assessment - Fire Suppression & Sprinklers - Part 7

    In this fire engineering design and risk assessment blog series for architects and others in the building design industry, we have been looking at fire suppression and sprinkler systems and how their use as part of a building’s fire protection plan affects the whole. In Part 6, we began looking at the potential benefits of sprinkler system installation on a design and will continue that theme in part 7. A suitable and fully-maintained sprinkler system...

  • Facilities Management & Fire Safety - Foam Systems - Part 20

    In this blog series for those who work in Facilities Management and have a responsibility for or interest in Fire Safety, we have been looking recently at Water Mist Systems and how they first came into use for the protection of ships and their cargo many years ago, through to the present day expansion in their use to residential buildings and the resulting British Standards that were recently produced. In Part 20, we’re going to...

  • Fire Engineering Design and Risk Assessment - Fire Suppression & Sprinklers - Part 6

    In this recent fire engineering design and risk assessment blog series for architects and others in the building industry, we have been looking at fire suppression particularly in relation to sprinkler systems. In part 5, we compared sprinklers to passive fire protection measures in terms of reliability when in use, as it has been argued that sprinklers are not 100% effective, which implies other measures are – they were not, of course.In part 6,...
