A Few Weeks Ago,

these photographs and video were doing the rounds, 

they are of several male employees at the ‘Development Office’ of Jagtial district, in Telangana, India, who have to wearing motorcycle helmets to prevent slabs of concrete from the ceiling falling on their heads, 

according to News Nine, the roof of the Mandal Parishad Development Office has been leaking since last year and is now in a dilapidated condition. The moisture has been causing pieces from the ceiling to fall off, and employees have been left with no choice but to protect themselves somehow, it might seem funny, but read on,

here in the UK school children may have to do exactly the same! I kid you not, this is one headline from a UK newspaper "Hundreds more UK school buildings could be crumbling" the article is here, apparently the government was still awaiting responses from about 1,500 schools in England that were sent surveys to identify those with Reinforced Autoclaved Aerated Concrete (RAAC), a lightweight form of concrete commonly used during the 1960s-80s but now considered weak and unsafe, so what is Reinforced Autoclaved Aerated Concrete? 

from this article:

"RAAC is a lightweight form of concrete used in roof, floor, cladding and wall construction in the UK from the mid-1950s to the mid-1980. We believe it was used by some municipal architects primarily in office and schools, but RAAC has been found in a wide range of buildings, not all of which are still in the public sector, the limited durability of RAAC roofs and other RAAC structures has long been recognised; however recent experience (which includes two roof failures with little or no warning) suggests the problem may be more serious than previously appreciated and that many building owners are not aware that it is present in their property".

as I write this just 6 hours ago a list of affected schools was published here, what is the phrase? 'People in glass houses should not throw stones' or in this case go to school with out a crash helmet!
