The inventions of Dimitri Dutruv Pt. 5

After hearing of a school that faced difficulty in its fire and bomb evacuation plans, due to severely limited space on the school grounds, Dutruv developed a system to offer protection from explosions or intense heat to crowds gathered a short distance from the source of such threats. This involved underground blast shields being situated in a protective ring around the site in question. The blast shields would be reinforced concrete, 75cm thick, 6m wide and 4m high, which could be raised to their full height within 0.45 seconds by a powerful system of hydraulics, which could be activated by a remote control when all persons were outside the protective ring. One prototype was actually installed in an Australian High School, but was removed after a trial evacuation when a Year 10 pupil was accidentally catapulted 15m into the air by a premature firing of the blast shield mechanism.

Several of the blast shield being removed after the Year 10 student, who can only be identified as "Jayden" after a court ruling which also prevents the school from being identified, recovered from his injuries. He was saved from certain death by landing in the school's outdoor swimming pool. Photograph provided by uair01.
