Work on construction of a natural draught cooling tower (its diameter at base is about 100 m and height is about 120 m) was at full swing. The site had a skyrack (used for vertical transportation of construction workers and supervisors) for going to height. One day, eight workers were travelling

(well within the limit) in it going to start the work in the night shift. Suddenly, the skyrack developed some fault at 15 m height and had a free fall. Four workers sustained minor injuries, three received major injuries, and one died on way to hospital.
