Workers identified as belonging to a high risk industry or occupation should be asked if they engage in high-risk job tasks for lead exposure. For example, house painters should be asked if they have been removing old paint (applied before 1978). If so, has the paint been tested for lead content? In a computer-based patient record system, each patient would be coded for industry and/or occupation at the time of initial registration. The computer could be programmed to alert the physician (under certain conditions) when the patient belonged to one of the high risk industries or occupations.
