Lifting capacity of workers
The plans for collecting the data were developed after interviews with law enforcement officials and manufacturers of police equipment, consultations with physical anthropologists, and a review of pertinent anthropometric literature. The data base consists of two components: detailed body measurements of approximately 3000 male law enforcement officers and short form survey responses on the height, weight, and age of approximately 10 000 additional officers.

There are several factors which affect the lifting capacity. These factors can be categorised under the following: (1) individual characteristics, (2) task variables, and (3) environmental conditions. This paper presents the methods used to determine the lifting capacity for male and female industrial workers, as well as the models developed to predict this capacity under several conditions of the task variables (height level, frequency, and box size). Since overloading and underloading in manual materials handling is undesirable, field data were collected to investigate the effects of job demands on manual materials handling injuries. As op,posed to the physiological approach no difference was found in the lifting capacity due to age. While both weight and work rate are important, work rate was a more effective and logical single measure of back injuries or stress than weight.

Horino, S. Environment factors and work performance of foundry workers. Journal o f Human Ergolog.v, Dec 1977, 6.2, 159-166. Environmental factors such as atmospheric conditions, lighting, noise, and dust in foundry factories of different sizes were evaluated by direct physical measurements and a subjective rating method using an ergonomic checklist. Working postures and subjective feeelings of fatigue of the workers were analysed in various types of foundry shops. The results showed that workload was highly connected with poor working postures and unfavourable arrangement of work space as well as with poor workplace environment, particularly in terms of dust and noise. Forward bending and squatting positions, which were attributable to the manual working height on or just above the floor level, occupied 70 90% of the actual working time handling large-sized casts, while the work using a table allowed workers more frequent erect standing postures. It seemed essential to redesign the fundamental working processes and to improve the work surface height. A comparison was then made as to performance patterns and electromyographic activities of main muscles between the traditional moulding work on the floor and the work at a newly developed hydraulic lift-table operated by foot pedals. The new table assured the worker of an optimal standing position and proved to be an effective means of redesigning the workspace.
