Audit is the conformity of the subject with the standard requirements and regulations. The goal of this research is to design an audit procedure for health, safety and environmental quality management system based on HSE-MS in the field of printing industry considering its special condition and requirements.   Methods: Considering the importance of audit methods and related results, in this study we have analyzed and investigated the weakness and strengths of three major methods of Auditing (D&S ,MISHA,OGP)and based on this we have developed and designed an audit method for print industry (AMPI) with five major criteria and twenty five sub criteria. Afterward the criteria were tested and weighted using ANP and DEMATEL methods with 15 questionnaires filled by field specialists, which later were analyzed by “super decision” software.   Results: the output results from “super decision” software shows that the indicator of “management and commitment” with the normal weight of 0.249 has the highest priority, “risk management” indicator with normal weight of 0.237 is the second, “performance Monitoring” with normal weight of 0.196 is the third and “personnel Management” with normal weight of 0.164 is the forth, and “workplace technology” with normal weight of 0.153 is the fifth indicator. The effectiveness “showed by D” of management and commitment has the highest value compared to the other indicators.   Conclusion: results of this research showed that the most important and effective indicator in the field of auditing the health, safety and environment quality management system in print industry is the indicator of “management and commitment”, and by implementing effective methods of management and commitment we can achieve standards more successfully in the field of auditing.}, Keywords = {Audit- management system- HSE- Decision-making models Versatile, ANP Model , DEMATEL Model}, volume = {12}, Number = {3}, pages = {1-14}, publisher = { Iran University of Medical Sciences}, url = {http://ioh.iums.ac.ir/article-1-1385-en.html}, eprint = {http://ioh.iums.ac.ir/article-1-1385-en.pdf}, journal = {Iran Occupational Health}, issn = {1735-5133}, eissn = {2228-7493}, year = {2015} } @article{ author = {Firoozeh, M and Saremi, M and Maleki, A and Kavousi, A}, title = {Investigation of Maximal Aerobic Capacity and Associated Factors in Firefighters}, abstract ={  Background and aims: Maximal oxygen uptake (VO2max) represents physical work capacity. Therefore in physically demanding jobs like firefighting, precise evaluation of employees' aerobic capacity is critical in order to ensure their physical capabilities and fitness for work duties. The aim of this study was to evaluate the maximal aerobic capacity and its associated factors in firefighters.   Methods: In this cross-sectional, descriptive, analytical study, 31 firefighters from suppression division of Tehran Fire Department were selected randomly. Socio-demographic questionnaire and also Tuxworth and Shahnavaz step test method were applied as research tools. Data were analyzed using descriptive and inferential statistics via SPSS19 software.   Results: The obtained results showed that the mean VO2max in firefighters was 36.18 ± 3.28 ml/kg/min. VO2max had a significant negative correlation with weight ( P=0.017, r= -0.43 ). There was no significant relationship between VO2max and marital status, having another job, smoking status , height, age group, BMI, and job title (α= 0.05).   Conclusion: The mean value of VO2max in firefighters was determined to be at average level according to its norm values (34- 42 ml/kg/min for age group of 20- 29 years old, 31- 38 ml/kg/min for 30- 39 years old and 27- 35 ml/kg/min for 40- 49 years old), and higher than the other job groups' reported values in other studies but, in comparison with firefighters of other countries, their VO2max was less. Due to the importance of firefighters' job and according to the results of our study, making effort to enhance firefighters' VO2max is really important.

However, there are some limitations in working with this equipment including equipment accessibility, necessity of highly trained operators, and the high cost of sample analysis. The aim of this study was to evaluate the performance of photoionization detector (PID) as a substitution for GC-FID in the measurement of toluene as a representative of the VOCs in experimental studies.   Methods: This study was carried out by an experimental set up for generating toluene known concentrations at 5, 20, 50, 100, 200, 500 and 1000 ppm with relative humidity 13% ±2. The concentration values were measured with PID as well as the National Institute of Occupational Safety and Health (NIOSH) 1501 reference method and results were compared.   Results: The results showed a significant difference between the two methods at concentrations higher than 50 ppm while there was no significant difference at 5 ppm and 20 ppm. The correlation coefficient of the toluene concentrations at 5 to 1000 ppm was 0.999. The correction factor for the PID was 1.05 at the studied concentration range.   Conclusion: Although the results presented by PID were different from those extracted from the NIOSH reference method, the response was linear.
