Iran Occupational Health

 Background and aims: All over the world, and particularly in industrialized countries, the transport of hazardous materials has till years a continuously increasing trend. Public concern is focused mainly on road and rail transport, since the routes used for road and rail transportation of hazardous substances necessarily come closer and sometimes also cross densely populated areas. In this study 322 accidents that occurred during the road transport of hazardous materials (hazmat) in Iran from 2008 to 2012 was carried out.

Methods: In this study, causes of accidents, accident frequency, characteristics of location, type of material involved in the accidents, the distribution of risks of accidents, accidents frequency, population affected by road traffic accidents, social risks of hazardous materials accidents and environmental factors affecting the distribution of the accidents were examined.

Results: The results showed , causes of accident were human factors (60.67%), followed by vehicle transport (17.83%), environmental factors (11.44%) and packaging and loading (10.06).

Conclusion: Study showed that the frequency of accidents has increased significantly in recent years and the need for improve safety measures revealed. Keywords: Hazmat transportation, Road accidents, Event tree analysis.

Background and aims: Work related accidents in the line of duty in the workplace occur and leading to fatal or non-fatal injuries. The aim of this study is investigation of the epidemiological accidents recorded in Qom Insurance Agency and provides an appropriate algorithm for accidents recordation.

  Methods: In this descriptive – analytical study, all the accidents recorded in the Qom Insurance Agency 2009 to 2012 were investigated. Data was analysis with version 16 SPSS and Excel using Fisher and Chi square test.

 Results: The results of this study revealed that, the most common types of all accidents were falling from height. Mortality status of all injured workers (death and non-death) and their jobs (unskilled workers and other workers) in two half of years and in two age groups (≤ 40 years and more than 40 years) at the 5% level of error have no significant relationship.The morality status of all accidents (death and non-death) with age (≤ 40 years and 40 years) in both groups experience (≤ 3 years and older than 3 years), at the 5% level of error have significant relationship.

 Conclusion: This study showed further explore for change existing procedure and reform of record keeping for the prevention of these accidents are necessary.

Introduction & Objective: Noise exposure, risk exposure in a wide range of work station, especially oil and gas industry and related companies is considered. This study was carried out to evaluate the noise before and after corrective action in 11 operational units of tanks and transportation in Abadan oil refining company.
Methods: First, the basic information including the location of noise sources and operating conditions of the equipment was collected. noise measurements was performed based on ISO 9612 standard before and after implementation of corrective actions, including repair or replacement of defective and worn out Parts or lubrication of moving parts 
and using SLM CEL 490 mode calibrated with CEL-110/1  of casella  company was performed.
Results: According to the results, the NTA has the highest amount of noise (97 dB) and spherical tanks with the lowest noise (82 dB). In this study, measured total 523 stations, 115 stations with noise levels over 85 dB, 373 stations between 65 and 85 dB sound pressure level and sound pressure level less than 65 dB in 30 stations.
After carrying out corrective measures to reduce noise measurements, result showed that reduction of average sound pressure level of unit 1 of oil pumping with the 2/39 dB, 1.7 dB with a unit of Control Center, pus oil pumping unit with 0.98 dB and NTA unit with 0.08 dB, carried out respectively.
Conclusion: Noise measurements showed that the NTA unit was one of the severest conditions from the viewpoint of noise pollution among the other units. This study confirms the need to identify the main sources of sound and prioritize different parts of the industrial unit in order to implement control schemes engineering.
