Explosion in Welwyn Hatfield leads to banning of substance

AN explosion, which injured two workers, at a pumping station has lead to the banning of a type of foam concrete.

Engineering contractors Barhale has stopped the use of the substance after a blast near Mill Green Museum in August.

The workers, who were decommissioning the Bush Hall Lane site, injured their feet in the accident.

The explosion was blamed on incinerator ash within foam concrete used as infill, on an HSE online discussion forum.
