Too many construction sites treat emergency planning as something to deal with later – rather than something to plan for from the outset. When teams put suitable arrangements in place early and meet their legal duties, they can respond to emergencies in a controlled and effective way.
Under the Construction (Design and Management) Regulations 2015, contractors must put emergency arrangements in place as a legal duty – even on small or short-duration projects.
What the Law Actually Says - Regulation 29
Regulation 29 states that:
Suitable and sufficient steps must be taken to prevent, so far as is reasonably practicable, the risk of injury during construction work arising from:
Fire or explosion
Flooding
Any substance liable to cause asphyxiation
Regulation 29 focuses on prevention – but contractors must also prepare for what happens if those risks materialise.
Planning for When Things Go Wrong - Regulations 30 & 31
Where risks remain, Regulations 30 and 31 require contractors to make “suitable and sufficient arrangements” for dealing with foreseeable emergencies including evacuation procedures and safe escape routes.
Those arrangements must take account of:
The type of work being carried out
The size and layout of the site
The equipment in use
The number of people on site
The properties of materials present
They must also:
Be communicated to everyone on site
Be tested at suitable intervals
Provide sufficient, clearly signed escape routes
Lead directly to an identified safe area
Be kept clear and unobstructed
What are CDM emergency procedures?
CDM emergency procedures are legally required arrangements under CDM 2015 that ensure construction sites can respond safely to emergencies such as fire, flooding or structural failure. They must be proportionate, clearly communicated and regularly tested.
Why Emergency Planning Gets Missed
We regularly see emergency plans that teams copy from previous projects, file away without communicating, or rely on as common sense. These gaps create real risk — and the Health and Safety Executive will quickly identify them during an inspection. Blocked evacuation routes caused by stored materials, sites with no clearly identified assembly point, expired or missing fire extinguishers, and subcontractor teams who have never taken part in a drill are an accident waiting to happen. Emergency planning only works if it is well thought out.
CDM-Compliant Emergency Prep Checklist
To meet CDM requirements, your site must have:
✔ A site-specific fire and emergency plan
✔ Clearly signed and unobstructed evacuation routes
✔ A named, trained fire marshal
✔ Weekly checks of alarms and extinguishers
✔ Worker briefings and practice drills
✔ Emergency contact details clearly displayed
Emergency procedures on construction sites must be site-specific, proportionate and regularly tested to meet CDM 2015 requirements.
Even Small Sites Must Plan for Emergencies
Even on domestic extensions, loft conversions or single-unit refurbishments, the duty remains. A smaller project does not remove the requirement for a basic written emergency plan, trained operatives who understand the procedures, and clear access routes for fire and ambulance services. CDM duties do scale with risk and complexity – but they remain proportionate and are still very much in place for small projects. If something goes wrong, people must be able to respond quickly and reach safety without confusion or hesitance.
Emergency arrangements are one of the simplest areas to get right, yet one of the most serious to get wrong. At Safety CDM, we help contractors and clients put proportionate, compliant emergency plans in place that reflect real site risks – not generic templates.
