A major fire at specialist recycler M&R Commercials in Wales involving around 4,000 tyres, cylinders, waste and scrap vehicles caused road closures and disruption to rail services.
The blaze broke out at an industrial estate in Fforestfach, Swansea, on the morning of 29 May, with around 70 firefighters involved in bringing it under control.
Members of the Mid and West Wales Fire Service (MWWFS) stayed on the scene to prevent any further flare-up. In all, crews from 13 local fire stations attended the incident.
Natural Resources Wales (NRW) said it was on-site to working with Swansea City Council and the fire service to help protect the environment and local people from the impact of the fire.
Several local people reported hearing explosions at the site on the morning the fire broke out.
MWWFS area manager Simon Jenkins said: “We would like to thank our firefighters for their excellent professionalism and commitment in bringing the fire under control. Faced with significant risk, their initial tactical planning has ensured this incident was brought to a safe and quick conclusion.
“While the fire has been extinguished, one fire and rescue appliance will remain at the incident until we are satisfied that the affected area has cooled sufficiently.
“The focus for MWWFS now turns to investigating the incident and working with NRW and the local authority to support the community and begin the environmental clean-up operation.”
Gareth Davies, NRW senior environment officer, said: “The fire service put measures in place to minimise the amount of contaminated water leaving the site. We also installed booms to contain any contaminated water which left the site in order to reduce the impact on the Fforestfach stream.
“As regulator of the site, we will be conducting an investigation with our partners to establish the cause and any action we may need to take.”
A fire investigation is currently underway.
