This paper presents near optimal solution method to find safe work place design using harmony search algorithm. Revised NIOSH equations are considered to minimize relative estimate of the physical stress associated with a manual-lifting job. The proposed algorithm will assist occupational safety and health practioners in evaluating lifting tasks and reducing the incidence of low back injuries i...
Purpose: Mechanical loading is said to be an important factor in the development of low back pain (LBP). One of the main concerns in manual material handling (MMH) tasks is lifting loads, as this activity is present in most jobs. Despite the controversy about their effectiveness, belts are used in industry as either protective or assistive devices in manual load handling. The present inve...
Prior research has shown the load moment exposure to be one of the strongest predictors of low back disorder risk in manufacturing jobs. However, to extend these finding to the manual lifting and handling of materials in distribution centers, where the layout of the lifting task changes from one lift to the next and the lifts are highly dynamic, would be very challenging without an automated me...
Background and aims : Manual material handling (MMH) can be lead to work-related musculoskeletal disorders and one of the most common disorders due to MMH tasks is low back pain. This study was conducted for determination of musculoskeletal disorders, assessment of MMH tasks by MAC and revised NIOSH lifting equation methods and compares the results of these two methods. Methods: This descri...
BACKGROUND Manual material handling is one of the major health and safety hazards in industry. This study aims to assess the lifting tasks, before and after intervention using NIOSH lifting equation and Manual Handling Assessment Charts (MAC). METHODS This interventional study was performed in 2011 in a tile manufacturing industry in Hamadan, located in the West of Iran. The prevalence of mus...
