'Tyre explosion' death inquiry at Pumsaint
Police and Health and Safety Executive officers are investigating after a man is understood to have died while blowing up a tyre at a business.
Emergency services were called to Thomas Rees & Son, Pumsaint, Carmarthenshire, at about 09:35 BST on Wednesday.
Dyfed-Powys Police said a man in his 30s died. His family have been informed.
Witnesses said the sound of the explosion was heard over a wide area.
The man who died has not been named but is understood to have been working in The Forge, a small family metal fabrication business in the centre of the village.
One neighbour who passed the Forge shortly after the accident said the man was taken to hospital by air ambulance.
He has not been officially named but the neighbour said it was particularly tragic because his partner recently had a child.
A police spokesperson said: "Dyfed Powys Police are working in conjunction with the Health and Safety Executive due to the incident being work-related, although no other persons are involved and the incident and scene does not present a danger to other members of the public."
Mid and West Wales Fire and Rescue service said two fire crews from Lampeter and Llandovery were sent to the scene.
