Comparing Data from the Poisons Information Centre with Employers' Accident Reports Reveal Under-Recognized Hazards at the Workplace

Abstract

Records of injuries and incidents provide an important basis for injury prevention related to hazardous substances at the workplace. The present study aimed to review available data on injuries and incidents involving hazardous substances and investigate how data from the Poisons Information Centre could complement the records of the Swedish Work Environment Authority. We found two major obstacles for using injury/incident data based on employers' mandatory reporting. First, it was not possible to quickly and reliably identify injuries caused by hazardous substances, and second, data identifying substances or products are not systematically included. For two out of five investigated injuries with lost working days likely due to chemical injuries, we could not identify substances and/or products involved. The records based on calls to the Poisons Information Centre allow better understanding of chemical hazards and products. Besides the large share of unidentified chemical hazards in the injury statistics, the most striking difference was found for cleaning agents. Cleaning agents were implicated in one-third of the occupational cases that the consulting Poisons Information Centre expert judged to pose a major risk and in need of immediate healthcare. Only one in 10 injuries with lost days reported by employers was related to this type of product. The identification of exposures and symptoms by the Poisons Information Centre allow recognition of chemicals with problematic occupational uses. Hence, these records may serve as an important complement to official injury statistics related to incidents with hazardous substances at work.
