Fire in Masquerade Club, closed for renovation, started with sparks from work and burned to third floor of 16-floor building. Victims were mainly workers engaged in the renovation and nightclub staff. Authorities have suggested that the club did not have a permit for the renovation work and that construction materials stored may have been ignited by sparks from the renovation work. Six people have been arrested including club owners and manager and the person responsible for the renovation. This fire shows the importance of fire resistance of construction materials not only in buildings but also during work phases of storage, installation and dismantling.
