Engineering expert says falling structure could generate 816kg of force at speed faster than human reaction time. Head of industrial accident concern group urges authorities to enforce detailed checks at similar structures citywide. — SCMP

A fatal accident involving the collapse of a motorised metal gate at a government health centre in Hong Kong may have been caused by sensor failure, according to an engineering expert.

On Monday night, a 4.7-by-2.5-metre metal gate at a maternal and child health centre in Yau Ma Tei fell and killed a 43-year-old female security guard. The case has been classified as an industrial accident and a police investigation is under way.
