JUST 10 days after the Government angered women's groups with sexually suggestive construction safety posters, the Hong Kong Construction Association has done the same thing. One of the association's posters, showing a cartoon of a busty, scantily clad woman, has been singled out as being particularly offensive, especially as the woman's skimpy shorts have been ripped on a protruding nail. ''We would like to see the poster either changed or banned,'' said Linda Wong San-yung, spokesman for the Federation of Women's Centres. The Labour Department posters show a model wearing safety clothing, but in suggestive poses and with suggestive captions. Hong Kong Polytechnic lecturer Catherine Ng Wak-hung described the association's poster as ''sexist and offensive in the way it portrays women as sex objects rather than professional people''. She said she would raise the issue with the Business and Professional Women's Association and the Association of Women for Arts and Research. Ms Wong said the poster was worse than the three posters produced by the Labour Department. ''The [association] poster uses the woman as a sex object to attract men to look at it,'' said Ms Wong, who also objected to the name of the woman, Miss Safety, written in large Chinese characters as chun nui at the top of the poster. On Thursday, the Association of the Rights of Industrial Accident Victims organised a demonstration outside the Labour Department offices in Central calling for the department's posters to be banned. Protesters handed in a petition and tore up copies of the posters. Women's groups are calling for similar tough action against the association poster, which has been produced with the Occupational Health and Safety Council. The bottom of the poster carries a construction safety slogan. ''The issue of site safety should be treated as a serious one,'' said a researcher in the Department of Surveying at the University of Hong Kong, Helen Linguard. ''Posters of this nature not only trivialise the safety problem but also make a mockery of professional women working to improve the situation. Female safety officers are not uncommon.'' She spends two or three days a week on construction sites and said these types of posters reduced the credibility of women on site. The association defended the use of the cartoon, which is part of a set which also features a macho-type man. ''We are not selling a sexy image, we are selling the safety message,'' said secretary-general, Patrick Chan Wing-tung. ''We are using the female to make her spread the word as a victim. To tell people how she suffers from people not observing site safety. We use a man to spread the word as a directive, that people should observe site safety,'' Mr Chan said. The design aimed to grab workers' attentions. But he said future posters could be changed if there were complaints about using the woman.
