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.
