Three softwares have been designed, the first for job histories, the s
econd for job-exposure matrices, and this, the third and latest, for w
orkplace descriptions. The first two softwares were presented in earli
er articles while the current article presents the software for workpl
ace descriptions. Workplace description has been based on the idea tha
t a job is best described by listing its constituent tasks so as to de
termine associated risks better. The three softwares, the job history
software (JHS), the job-exposure software (JES) and the workplace desc
ription software (WDS) are interfaced and constitute an integrated pro
fessional risk surveillance (PRS) system.
