Hello. If you manage an industrial unit, warehouse or workshop in North Wales, use the recent Llay fire as a prompt to review your fire protection and business continuity arrangements.
According to The Leader, a fire at a scrap-metal yard on Llay Industrial Estate began at about 7pm on Wednesday 7 October 2026. North Wales Fire and Rescue Service reported that the fire was out at 9.45am on Monday 12 October. Twelve fire engines attended at the height of the incident. Crews remained on site to tackle hotspots and monitor conditions, while Natural Resources Wales monitored potential environmental impacts.
The cause was still under investigation in the report. The incident is not a reason to speculate or panic. It is a practical reminder that a fire involving industrial materials can demand a sustained response, with consequences for nearby businesses and the wider area.
Why early detection matters
A large unit can contain long aisles, high racking, machinery, packaging and combustible stock. If a fire starts in a quiet area, it may develop before anyone sees it. Smoke and heat can travel through open spaces, while stored materials may add fuel and obstruct access.
Early detection gives people more time to raise the alarm and evacuate. It can also give responders earlier notice of an incident. It cannot guarantee that a fire will be contained, but delay can reduce the options available.
Review whether your fire alarm system suits the building’s size, layout, occupancy and risks. A competent designer can advise on the appropriate system and detection for the site. In a large or complex premises, automatic detection, suitable warning devices and clear instructions are important parts of the plan.
Make alarm zones useful
Alarm zoning should help staff and responders identify the affected area quickly. A zone plan should be available beside the fire alarm control panel and should match the current site layout.
Check that:
- The panel’s zone information is clear and accurate.
- Changes to walls, racking, partitions or room use are reflected in plans and system records.
- Staff know how to raise the alarm and what to do when it sounds.
- Alarm audibility and, where required, visual warnings have been considered across noisy or occupied areas.
- System faults and isolation arrangements are reported, recorded and acted on.
Do not treat an alarm panel as a substitute for a fire-risk assessment. The alarm system needs to work as part of an overall plan for evacuation, emergency response and site management.
Cover out-of-hours periods
A fire may start when a site is closed or only partly occupied. Consider how an alarm activation will be noticed and actioned at those times.
Monitored signalling to an Alarm Receiving Centre (ARC) can provide an agreed route for passing alarm signals to a response process. Confirm who receives the signal, what they are expected to do, which contacts are current and how faults or communication failures are handled. Remote signalling is not a replacement for suitable local alarms, maintenance, staff procedures or emergency-service attendance.
Test the out-of-hours process. Update contact lists when staff or site responsibilities change. Make sure any agreed escalation procedure is understood by the people who need to use it.
Limit fire spread and manage storage
Detection can give an early warning, but fire-resisting construction helps limit spread. Inspect compartment walls, fire doors, shutters and service penetrations. Check that doors close properly and that gaps around pipes and cables are appropriately sealed. Alterations and new services can compromise fire separation if the work is not checked.
Storage practice matters too. Keep escape routes, fire exits, electrical rooms and access for responders clear. Control the height and quantity of combustible stock and packaging. Separate waste and potentially hazardous materials from ignition sources. Do not store goods against fire doors or where they could interfere with shutters and other protective measures.
For warehouses and factories, the government’s fire safety risk assessment guide provides a useful reference. The right arrangements depend on the building and the work carried out there.
Control hot work and electrical risks
Welding, cutting, grinding and similar tasks can introduce ignition sources. Use a suitable permit-to-work process where required. Before work starts, identify nearby combustible materials, protect them, and check whether sparks or heat could affect the other side of a wall or floor. Set out who will monitor the area during and after the task, and record when the work area has been checked.
Electrical faults can also create a fire risk. Arrange inspection and testing of fixed electrical installations at appropriate intervals, based on the premises and the advice of a competent person. Deal with defects promptly. Check for damaged leads, overheating, overloaded sockets, poor connections and unauthorised changes. Keep electrical equipment and distribution areas free from unnecessary storage.
These controls are most effective when they are part of routine site management. Assign responsibility, document checks and review them when operations, equipment or storage arrangements change.
Consider suppression and emergency lighting
Sprinklers and other suppression systems should be considered through a site-specific risk assessment. The appropriate solution depends on the building, the materials stored, the processes involved and the likely fire hazards. Get competent advice on design, maintenance, water supplies and how system impairments will be managed.
Emergency lighting supports evacuation if normal lighting fails. Check that fittings are positioned for escape routes and exits, and that inspections and tests are recorded. Keep escape routes unobstructed and make sure staff understand the evacuation procedure.
Dragon designs, installs, tests and maintains fire alarm systems and emergency lighting. Our fire services and electrical services include support for commercial and industrial premises. Planned preventative maintenance (PPM) contracts can help keep checks, servicing and records on a regular schedule. Maintenance does not replace the duty to review a fire-risk assessment or correct hazards found on site.
Plan for business interruption
A prolonged incident can affect more than the building where it starts. Businesses may face interrupted trading, damaged stock, unavailable machinery, delayed orders, missed contracts and staff disruption. Neighbouring sites may also be affected by access restrictions or smoke.
Prepare a continuity plan before an incident. Identify critical equipment, data, suppliers and customers. Decide how you will communicate with staff and customers, where essential work could be moved, and who will speak with your landlord, insurer and emergency services. Keep contact details and site plans current. If you rely on a single site, consider what you would do if access were restricted for several days.
The Llay incident showed that emergency work may continue after the initial response, as crews deal with hotspots and monitor the site. Your plans should account for investigation, access restrictions, clean-up and recovery, not only the first evacuation.
Review your arrangements
Use this checklist to start:
- Review your fire-risk assessment and update it after changes to the site or its operations.
- Check fire alarm coverage, zoning, warning devices, panel information and out-of-hours procedures.
- Inspect fire doors, compartmentation, escape routes and service penetrations.
- Review storage, waste, hot-work and electrical controls.
- Confirm emergency lighting tests and fire alarm maintenance are up to date.
- Check whether suppression systems are appropriate and properly maintained.
- Test your business continuity arrangements and update contact information.
