The possibility of stalls having to be dismantled after trading hours drew a hostile response from hawkers. Street traders spoke out after Chief Executive Donald Tsang Yam-kuen said the government was considering the requirement among new safety measures after Wednesday's fatal fire at a Mong Kok market. Wong Pui-ching, chairman of the Fa Yuen Street Hawker Association, said it was premature to blame stall owners alone for the fire. 'What caused the blaze is still unknown, so it is unfair to put the blame on us,' Wong said after meeting officials. Brenda Cheng So-ngor, chairwoman of the Federation of Hong Kong, Kowloon and New Territories Hawker Association, said dismantling stalls would be too difficult for many traders. 'Most of the 200-odd licensed hawkers here are over 60 - and can be as old as 90 - so it is impossible for them to move the iron bars and pack up the stock ... every night.' The Food and Environmental Hygiene Department said licensing conditions would have to be altered if stalls are to be dismantled at night. The agency and the Fire Services Department had begun city-wide safety checks of fixed-pitch stalls, including those at Jardine's Bazaar in Causeway Bay and Li Yuen Street East and West in Central. Traders were also worried about their costs increasing if stock cannot be left on stalls overnight. 'We will have to rent a warehouse to keep the stock at night - and the business is not so good,' said one hawker who lost a HK$20,000 batch of slippers in the fire.
