On November 30, 2001, LS Grant helped an officer evacuate colleagues from a smoke-filled diving chamber after the oxygen lines on one diver's breathing apparatus exploded and caught fire at a research facility in Toronto Ontario. LS Grant was working in a nearby lab when the accident occurred. Although aware of the explosive potential of the canisters of compressed gas fitted to the burning breathing set, he donned an emergency breathing apparatus and rushed inside the unit. He then cut the sensor cords from the divers and assisted the officer in escorting the victims out of the hatch. Only when he had ascertained that everyone had also made their way out of the dangerous chamber did LS Grant follow them to safety.
