Smoking policies in the workplace in the western Cape.

A postal survey of workplace smoking restrictions among the member organisations of the Cape Chamber of Industries was carried out in 1989. The response rate was 57.1%. Of the 572 respondent organisations, 66.1% had some smoking restrictions. Large workplaces were more likely to restrict smoking than small workplaces: 42.0% of those with fewer than 10 employees had restrictions, increasing to 90.9% of those with more than 500 employees. Organisations producing manufactured goods (other than engineering) were more likely to have restrictions than non-manufacturing concerns. Smoking was commonly restricted on the factory floor (61.3%) and in warehouses (55.8%), but only 7.4% prohibited smoking in shared offices. The reasons for smoking restrictions stated most frequently were the fire hazard (85.3%) and legislation (66.0%). Only 29.1% stated that health care concerns were an important reason for restrictions, while a further 16.3% stated that health was a minor reason for restrictions. Of the respondents, 48.4% expressed a need for guidance in improving their smoking policies. These results indicate that there is considerable potential for intervention to decrease both active and passive smoking in local workplace settings.
