  Assessing the risks related to the advancement of science and technology has always been accompanied by many uncertainties. As a new field of science, nanotechnology faces numerous uncertainties concerning safety, health, and environmental aspects dealing with which requires a proper risk assessment. Accordingly, this study intended to assess the risk of tasks associated with nanomaterials comparatively, examining the risks in eighteen companies in Tehran. The two proposed risk-assessment methods for the activities involving nanomaterials (NanoTool and Guidance) assisted in assessing the risk of their tasks. The results were analyzed using SPSS.22 and the chi-square test and indicated the different outputs of the two methods despite being designed based on the control banding approach. These differences could be attributed to the different risk-assessment parameters that these methods considered. The statistical analysis results also showed no significant relationship between them. Given the large differences and insignificant association between risk assessment results, the guidance method was less effective than the nanotool method. However, straightforwardness and convivence of implementation in the workplace and various research environments make it a helpful method in initial evaluations. پرونده مقاله

  Control of Substances Hazard to Health (COSHH) Essentials is a simple, user-friendly matrix that provides risk-control solutions. Considering a large number of small enterprises under 25 workers in Iran and the lack of a suitable control banding tool, the COSHH Essentials can be considered an appropriate option. The purpose of the present experimental semi qualitative study was to evaluate the validity of the COSHH Essentials tool. Six processes were selected from a chemical products industry, including the production of silicone glue, polishing, PVC glue, Grease, Twin glue filling, and quality control. Amorphous silica and toluene concentrations were monitored using NIOSH 0600 and NIOSH 1501 in the ambient air of operators. The predicted exposure range (PER) was obtained by combining the control strategies available at the sampling time with exposure predictor (EP) bands in the COSHH Essentials, then compared to silica and toluene concentrations in the air.All exposure data were within the PER for amorphous silica dust and lower or within the PER for toluene. Compared to the acceptable concentration range in hazard bands, the threshold limit value (TLV) for respirable dust is within the acceptable concentration range, while toluene TLV exceeded it. COSHH Essentials is a conservative and safe tool, especially in liquids. Due to its simplicity, ‎employers and health center experts can use the COSHH tool successfully for small enterprises or ‎as a screening tool before a comprehensive risk assessment. پرونده مقاله
