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

  • Fire Engineering Design and Risk Assessment - Firefighting - Part 14

    In LWFs fire safety engineering blog series for Architects and others in the building design business, we have begun to look at firefighting. In part 13, we began to look at how firefighting can be undertaken by the occupiers of a building if a fire starts. The use of portable fire extinguishers was discussed along with relevant training was discussed. In part 14, the provision of hose reels and the standards involved will be covered.

  • Fire Safety for Healthcare Premises - External Fire Spread - Part 48

    In LWF’s blog series for healthcare professionals, the aim is to give information on best practice of fire safety in hospitals and other healthcare premises. In part 47 of this series, LWF took a look at the use of sprinkler protection in healthcare venues and in part 48, we begin to discuss the potential for external fire spread and what precautions should be taken to avoid it.It should be borne in mind that we...

  • Facilities Management & Fire Safety - Fire Safety Engineering & the Prescriptive Approach - Part 5

    In LWFs blog series for those who work in facilities management or who have an interest in or responsibility for fire safety, we have been looking at the term ‘Fire Safety Engineering’ and what it involves. In part 4 of the series, we began to look at the differences between fire prevention and safety based on prescriptive codes and fire safety engineering. In part 5, we will continue from that point by looking at the...

  • Fire Engineering Design and Risk Assessment - Firefighting - Part 13

    In LWF’s fire engineering blog series for architects and others in the building design business, we began discussing firefighting. In part 12, an overview of the term and its meaning before looking at the method of firefighting, namely the strategy, tactics and operations of the Fire Service in the UK and equivalent organisations in other parts of the world. In part 13, we look at firefighting by occupiers of a building.Firefighting undertaken by occupiers...

  • Fire Safety for Healthcare Premises - Sprinklers - Part 47

    In LWF’s blog series for healthcare professionals, the aim is to give information on best practice of fire safety in hospitals and other healthcare premises. In part 46 of this series, we looked at the tank arrangement for sprinkler systems and how each pump should be arranged to draw water from either tank, so that any one tank or pump can be isolated. In part 47, we continue from that point on the subject of...
