In a fire incident during the early hours in an hotel under construction, two construction workers became unconscious. It is suspected that a cigarette butt thrown by some worker or short circuit aided with presence of lot of decorative material and construction wood, etc led to this incident. Little care is taken generally during construction phase as such incidents occur regularly in various parts of the world. Electrical connections used for portable tools are generally without any plug and socket arrangement, no proper earthing, damaged/twisted cables, etc and it is accepted as a practice in the construction industry. People also store paint and thinner tins, wood, etc in a congested room and this can lead to fire incidents.
