Angus has been involved in developing and writing British and International Fire & Safety standards since the mid-1980s. The list of standards that he has participated in is impressive and includes BS5839-1, BS8629, EN54-18 and ISO7240-2. Angus utilises his extensive experience to provide an authoritative perspective on the key issues that affect the Fire & Security Industry today.
Construction Fire Safety needs to be managed from the earliest stages of design and needs to address the risks both to site workers and to site neighbours. The majority of fires can be prevented by designing out risks, taking simple precautions, and adopting safe working practices.
Construction (Design and Management) Regulations 2015 (CDM) define duties in relation to fire safety at the construction site and identify factors that should be taken into account when making fire safety arrangements; the Regulatory Reform Order 2005 sets out who is responsible for enforcement. Although the legislation has changed in recent years, the requirements for fire risk assessment remained the same.
CDM Regulation 29 requires that "Suitable and sufficient steps must be taken to prevent, so far as is reasonably practicable, the risk of injury to a person during the carrying out of construction work arising from - (a) fire or explosion; (b) flooding; or (c) any substance liable to cause asphyxiation." CDM Regulation 30 requires that "Where necessary in the interests of the health or safety of a person on a construction site, suitable and sufficient arrangements for dealing with any foreseeable emergency must be made and, where necessary, implemented, and those arrangements must include procedures for any necessary evacuation of the site or any part of it."
The principal contractor should always ensure that Fire Safety Risk Assessment is carried out in accordance with fire safety legislation.
Fire Detection and Fire Alarms for Construction Sites
Fire warning systems must ensure that people on the construction site are alerted to make their escape before a fire spreads. The fire warning signal must be distinctive, clearly audible above any other noise and recognized by all the people on site. Fire alarm systems should often be fitted as part of the construction work.
False alarms and unwanted fire signals can be costly on any construction project however careful selection of fire safety systems can reduce this nuisance.
Different methods of giving fire warnings vary from site to site.
- on very small open-air sites ‘word of mouth’ may be adequate
- on a very limited number of open-air sites that a shout of ‘fire’ might not be heard or could be misunderstood, a small self-contained proprietary fire alarm unit may well be required
- on the majority of construction sites wired-in or wireless system call-points and sounders will be required to provide an effective fire warning system in order to meet the requirements of BS 5839
- Visual alarm systems should be considered for noisy areas or where there are workers who suffer from a hearing impairment
Although automatic fire detectors should not be fitted during construction work sometimes on high-risk sites or in temporary accommodation units such as site offices, if there are locations where a fire might occur and develop unnoticed until it threatens people’s means of escape, detectors may be appropriate.
When a fire is detected and the alarm raised, everyone should make their immediate escape without delay. In case of a false alarm, the procedures to verify the outbreak of a fire should be developed.
How to make your site fire alarm system effective and operational?
A nominated and competent person should do weekly checks and tests. Also, periodically service and any necessary rectification or repair should be carried out by a competent person who has an appropriate level of training and experience.
The work should be carried out in accordance with the supplier’s instructions or, where relevant, to an appropriate standard, for example, BS 5839.
All the records of the work carried out should be recorded. It is especially important to ensure that, as the site develops, the alarm system is modified so that effective coverage of the entire site is maintained.
General means for communication should be tested daily, eg portable radios or any intercom devices should be checked at the start of shifts. Servicing should be in accordance with supplier recommendations.
Firefighting Equipment for Construction Sites
The primary purpose of fire extinguishers is to prevent fires to become larger or to aid an escape. Fire extinguishers should be located on hooks or stands to keep them above ground level.
Extinguishers should be provided appropriate to the risk:
- Water, dry water mist or foam for wood, paper, card etc (Class A)
- Foam, dry water mist or dry powder (not to be used inside unless necessary) for flammable liquids (Class B)
- CO2, dielectrically tested foams (up to 1000V) and dry water mist (up to 1000V) for electrical risks
Fire extinguishers should comply with the standard BS EN 3–7: 2004 and they should be regularly checked, properly maintained and in case of an accident, properly used. Examination of fire extinguishers and hose reels should be done at least annually in accordance with BS 5306: Part 3, 2009 and BS 5306: Part 1, 2006. The work should be carried out by a competent person who has received appropriate training. The date and results of the examinations should be recorded, often on a service sticker attached to the individual piece of equipment.
Fire extinguishers for class A materials recommend a minimum quantity of extinguishers with an A rating should be calculated as follows:
- For any storey with a floor area less than or equal to 400m2, there should be at least two extinguishers with a class A rating; having a combined minimum total fire rating of 26A
- For any storey with a floor area exceeding 400m2, there should be at least two extinguishers with a class A rating; having a combined minimum total fire rating of 0.065 x floor area of the storey (in square metres)
- Extinguishers should be provided for other risks as appropriate
More complex sites may require wet or dry risers to be fitted; some may need sprinkler systems.
All fire-fighting equipment should have clear operating instructions with it. Those carrying out higher-risk activities, such as hot work, need to be competent in the use of the fire-fighting equipment and training should be provided.
Larger and more complex structures, such as multi-storey buildings, may have fixed fire-fighting systems installed. These may range from dry and wet risers to automatic sprinkler systems. Dry and wet risers are provided for the fire service to tackle a fire quickly. The continued availability of these in existing buildings, and their early commissioning in new buildings, is therefore recommended.
Fire extinguishers may be required for specific risks particularly when processes such as hot cutting are taking place but otherwise should be provided according to BS5306 part 8 2012 guidance. Multipurpose fire extinguishers are available, and the ratings of each extinguisher should be examined.
Emergency Lighting for Construction Sites
Emergency lighting to illuminate the escape routes and for illuminating specific tasks will be required on all but the simplest sites where borrowed or spill-lighting may be adequate.
Effective site management is critical and preventing fires from starting and growing is key.

Following the recommendations of BS5839 Part 1 2017 (Fire Alarm British Standard), it is a mandatory requirement to have an up to date, clear and accurate Fire Alarm Zone Chart adjacent to your Fire Alarm Control Panel and any repeater panels you have in your premises.
The purpose of the Zone Chart is to assist persons responding to an alarm to quickly identify the specific location in the building and to help the Fire Brigade understand the building layout before they enter.
When the Fire Alarm System is installed, the building is divided into Fire Zones. Any Manual Call Point (Red Box) or Fire Detector that is fitted will trigger a particular zone when activated.
The Zone Chart shows the division of each zone area with a ‘You are Here’ arrow to identify the position of the Fire Alarm Panel. The view of the building should be orientated in relation to the Fire Alarm Panel position to minimise confusion.
What is involved in producing a Zone Chart?
- Hard copy
- Or preferably AutoCAD (dwg) format
