BACKGROUND: Workplace disability management programs are important in managing injury and disability. METHODS: A stratified random sample of 188 employers in health care workplaces (71 hospitals, 48 nursing homes, 42 private clinics, and 27 community clinics) completed a mailed Organizational Policies and Practices (OPP) questionnaire. The OPP asked questions about eight workplace disability management practices. This article compares disability management practices across the four types of health care workplaces. RESULTS: A one-way analysis of variance for each of the eight practices demonstrated significant differences across facility types for all practices, except ergonomic practices. For unionized versus non-unionized workplaces, there were significant differences in all practices, except ergonomic practices. For workplaces with formal policies versus those without policies, there were significant differences in all practices, except people-oriented culture and safety diligence. CONCLUSION: Variations in disability management practices in health care workplaces need to be addressed to provide more effective prevention and treatment of work-related injuries and disability.
An accident occurs during the manufacture of cobalt sulphide unit due to liberation of hydrogen sulphide. Problems associated with the hydrogen sulphide and the recommended preventive measures have been discussed.
This study investigates the inherent optical properties (IOP) of a Brazilian river during a non-natural, anthropogenically mediated, toxic spill of a wood-pulping factory (the 'Cataguazes accident'). The results indicated an outstanding transformation in the river water chromophoric dissolved organic matter (CDOM) pools. For instance, increases in CDOM absorption coefficients, a(CDOM)(lambda), which were averaged at specific spectral intervals, [see text], ranged from 58-fold at the UV-B and UV-A ranges to 95-fold at the PAR range. As a result, the water color expressed as CDOM absorption at 440 nm, a(CDOM (440), varied from 4.16 to 365.03 m(-1). For S-coefficient, the variations ranged from approximately 1.1 to 5.6-fold, respectively, at the 300-650 nm and UV-B range. The variability of S as a proxy of dissolved chromophores was thus clearly influenced by the spectral range used. Optical proportions were also investigated through the use of [see text] and S ratios at the UV-B, UV-A, and PAR ranges and, in the case of [see text], also at the NIR range. This approach also showed clear variations between the water samples, likely reflecting changes in the composition of optically active substances in the river system. As a whole, the findings obtained here indicated that both the quantity and quality of the chromophoric material dissolved in the river water were greatly altered by the toxic spill. The changes in the optical properties of the river water, although extreme and likely with no parallel in the literature, were quite rapid as indicated by the optical resilience of the system. Overall, this study indicates that IOP might be thought, and possibly used, as a metric tool for monitoring the state of waters and aquatic ecosystems.
