The Fire and Rescue Service remain on site in Chirk damping down hotspots and it is hoped the incident will be handed back to Kronospan for their personnel to continue damping down any material in the near future.

All agencies agreed that this is a significant incident and as such, Natural Resources Wales has brought in a specialist mobile pollution monitoring station up from South Wales to Chirk to monitor air quality. Air quality data is now being used to help inform our advice and response

Officers from Wrexham Council will continue to liaise with all other agencies and endeavour to keep residents advised of any issues relating to this incident.

Public Health Wales advice remains as follows:

If you are in a place affected by smoke, stay indoors and keep doors and windows closed when affected by the smoke, but open them again to air your home when the smoke passes. If you need to be outdoors, avoid areas affected by smoke or ash, or limit the time you spend in them. Motorists who have travel through the smoke should keep windows closed, turn off air conditioning and keep their air vents closed.

Smoke can irritate airways, the skin and the eyes leading to coughing and wheezing, breathlessness and chest pain. This can also mean that problems such as asthma get worse; people with asthma should carry their inhaler with them at all times.

Odours associated with fires can cause annoyance, stress and anxiety, nausea, headaches or dizziness. These are common reactions to odours, rather than to the substances that cause the smell. We are able to detect odours at levels that are much lower than can cause harm to health.

Anyone concerned about their symptoms should contact their GP or NHS Direct on 0845 46 47. The symptoms usually disappear quickly and should not lead to long-term health problems.
