Abstract summary 

Chemical hazard communication is intended to alert users of the potential hazards of chemicals. Hazard information needs to be understood and recalled. Recall of hazard communication is critical when the written form of the information is not available at the time it is required.A cross-sectional study investigating associations between recall of chemical safety information on labels amongst 402 participants including 315 workers and 87 consumers in two provinces of South Africa.Respondents were predominantly male (67.7%), the median age was 37 years (IQR: 30-46years) and less than half of the participants completed high school (47.5%). Multivariate analysis identified the following positive associations with the recall of all the label elements listing the strongest association: call appropriate services and industrial vs consumer sector (OR=2.4; 95% CI: 1.2; 4.6 ); call appropriate services and transport vs consumer sector (OR=4.4; 95% CI: 1.2; 16.0); flammable symbol and male vs female gender (OR=2.3; 95% CI: 1.0; 5.3); flammable symbol and home language English vs African languages (OR=6.6; 95% CI: 2.1; 21.2); any hazard statement and home language Afrikaans vs African languages (OR=14.0; 95% CI: 3.6; 54.2), any first aid statement and further education vs none (OR=3.3; 95% CI: 1.3; 8.0), correct chemical name and industry blue collar workers vs non-industry blue collar workers (OR=2.6; 95% CI: 1.1; 6.1), correct chemical name and non-industry white collar occupations vs non-industry blue collar workers (OR=2.7; 95% CI: 1.0; 7.1).The study found a number of potential positive associations which influence recall of label elements of which some (e.g., sector, gender, occupation) suggest further research. Relevant policies in South Africa should ensure that the safety information on chemical labels is clearly visible to read and understandable which aids recall and the reduction in harmful chemical exposures.
