| Summary: | Two mmSDSs were developed, the first for two, similar, formaldehyde-based embalming fluids, the second for a solvent-based paint. Workplace and laboratory intervention studies were undertaken to evaluate the effectiveness of the mmSDSs in increasing knowledge of the products hazards and risks; inducing attitudinal and risk perception changes; appropriate protective behaviour and decreasing inhalation exposure. Subjects received either the mmSDS or the conventional SDS package, with subjects being assessed both pre- and several times post-intervention. Fourteen embalmers participated in the workplace evaluation. Knowledge increased, with more mmSDS users showing increases at the first post-intervention study. Cumulative exposure to formaldehyde decreased slightly post-intervention, although there were no significant differences between packages. There was little change in the use of protective measures due to embalmers already using measures available. Twenty-four members of the general public participated in a laboratory-based painting study. None had previously used the paint and knowledge increased for both mmSDS and SDS users. The mmSDS was more effective at promoting positive changes in the wearing of masks, hand washing and ventilation. Cumulative exposures to solvents decreased, although there were no statistically significant differences between packages. The impact of the mmSDSs and SDSs interventions on participants’ behaviour and exposure to chemicals was more pronounced in the laboratory study however the majority of the workplace participants were already using all the protective measures available. Overall, the findings suggest that the mmSDS concept may be an effective method of providing chemical hazard and risk information in the workplace.
