When was Fire at constructuon site of Subaru Telescope on Mana Kea Hawaii?

Answer 1

On January 16, 1996, foam insulation caught fire during the construction of the Subaru Telescope on Mauna Kea. Three construction workers died of smoke inhalation and twelve more were hospitalized, at least three of them overnight. One worker was rescued from the observatory's roof by a fire helicopter. Two days later, authorities reported that the fire had apparently been started by a cutting torch.

A fourth worker died in a forklift accident during construction. There is a memorial to all four workers on the outside of the telescope dome at ground level, accessible to the public, and every January, Subaru staff place a temporary sign at the bottom of the Mauna Kea Access Road with their names and the saying, "Look Up And Remember."
