Exploding concrete banned:Workers harmed
Contractors are banning foam concrete on civil sites after two explosions left construction workers with fractured feet. The blasts were linked to the use of incinerator bottom ash (IBA) in foam concrete. At least two contractors – Barhale and Enterprise – have banned foam concrete containing IBA from all their sites, with others understood to be following suit.
Well, we now read that the Highways Agency have issued a guidance note (Interim Advice Note 127/09 The Use Of Foamed Concrete) in which they advise that “foamed concrete containing IBA must not be used on any Highways Agency contracts from the date of this document until the HSE investigations are complete“.
IBA,apparently contains aluminium (which means it contains lots of heavy metal poisons as well)which reacts to form explosive gases.You really couldn't make it up!
