Hand Placement in Manual Materials Handling
Human Factors: The Journal of the Human Factors and Ergonomics Society, 1983This paper reviews the use of handles on containers and manually propelled vehicles. It is concluded that handle shape and size are relatively easy to define, but placement of handles on containers represents a more difficult problem. Laboratory and field studies of hand and handle placement are reviewed with the conclusion that handles should be ...

Wrist Deviation in Manual Materials Handling
Proceedings of the Human Factors Society Annual Meeting, 1983In fitting the Manual Materials Handling task to the operator, the interface between the human body and the object handled is of considerable importance. Design of handles in particular is an area in which design data are needed. As a box is raised or lowered, the operator must accommodate to the handles by deviating the wrist. An experiment to measure

Influence of restricted space on manual materials handling
Ergonomics, 1985Restricted space affects performance on any task requiring movement. Three ranges of available space are denned as a first step to determining workspace requirements. In the first range, the task is physically impossible due to anthropometric restrictions. In the second range, performance increases as space increases.

Prediction of metabolic rates for manual materials handling jobs
American Industrial Hygiene Association Journal, 1978A mew approach for estimating metabolic rates for manual materials handling jobs is presented. This approach was applied to 48 different jobs. The model validation showed a correlation coefficient of 0.95 between the measured and predicted metabolic rates. The coefficient of variation (standard error/sample mean) was 10.2 percent.

Evaluation and Quantification of Manual Materials Handling Risk Factors
International Journal of Occupational Safety and Ergonomics, 2003This study investigated the ability of the Revised NIOSH Lifting Equation (RNLE) to measure the risk of low back injury as verified by employee health outcomes. In addition, several basic risk factors and combinations of risk factors presumed related to low back disorders were explored.

An Ergonomics Approach for the Design of Manual Materials-Handling Tasks
Human Factors: The Journal of the Human Factors and Ergonomics Society, 1983The frequency, severity, and cost of manual materials-handling (MMH) injuries dictate that the design of these tasks and the assignment of employees to them ensure that the demands of the job do not exceed the capacity of the worker. This paper proposes the use of the job Severity Index (JSI) as a tool for job design and employee placement.

Manual Materials Handling: Case Study at a Portuguese Handling Company
2019Manual Materials Handling (MMH) represents a significant part of the tasks carried out by workers across several economic activity sectors. However, there is a big discrepancy between working conditions and workers actual needs and limitations, and this reflects in the high rate of work-related disorders, particularly, the low back pain, due to ...

Combining Stress for Manual Materials Handling
1986Abstract A wide variety of manual materials handling is performed in hot environments, however, little data exist on the effects of hot environments on lifting capacity. This study was conducted to assess lifting capacity in hot environments, investigate the stresses imposed on the worker under these conditions, a fuzzy model was developed which ...

Modeling in manual materials handling.
Journal of human ergology, 1998Manual materials handling (MMH) account for approximately $15.0 billion of injuries cost in the United States alone. Because of the need to establish manual handling guidelines, different approaches to achieve this goal were pursued. Such approaches are based on biomechanics, work physiology, and psychophysics.
