- Discomfort in the use of personal protective devices (PPD) has been one of the chief causes of their non-use. A field trial using industrial helmets was carried out to ascertain whether by training and repeated wearing subjects could experience a significant adaptation to discomfort. Ten subjects took part in the trial in a tropical environment by wearing helmets repeatedly (6 h a day) for one month. Subjective evaluations of discomfort were made at the end of the 1st, 3rd, 5th, 14th and 30th day. It was revealed that complaints of discomfort, viz. hotness, heaviness, bad fit, etc., decreased markedly throughout the 30 day period. Though positive responses of adaptation to discomfort seem to reach an optimum towards 30 days, it is difficult to draw any conclusions on the optimum period of adaptation for each discomfort factor. In relation to inherent discomforts that are extremely difficult to overcome without compromising the protection efficiency of a PPD, the principle of adaptation seems to be a very important facet which has to be developed for an effective PPD programme.

A model of ergonomics intervention in industry : case study in Japan
- 1994

In: Journal of Human Ergology. - 0300-8134. ; 23:1, s. 7-26

Journal article (peer-reviewed)abstract
- This paper presents the results of an ergonomics survey in four different Japanese work places. The survey consisted of two parts. In the first part, the physical and psycho-social problems of the female workers were investigated. Questionnaire techniques were used to assess musculoskeletal disorders in various parts of the body and of psycho-social stress at work as well as in the daily life situation. Furthermore, work posture analysis, task analysis, simple clinical tests and flexibility tests were conducted. In the second part, the ergonomics intervention practices in different types of Japanese work places were examined. Three different questionnaires were developed and used to collect information from representatives of employees, management and responsible governmental agents of the Department of Industrial Safety and Health, Ministry of Labor, with regard to ergonomic interventions at work places. Management, employees, and government representatives expressed desire for cooperation and participation for arrangement of the ergonomics intervention program. A model for appropriate ergonomics intervention in industry is developed with regard to physical and psycho-social problems at work. Factors influencing worker participation and the establishment of a dynamic system of ergonomics intervention at work places are discussed. Practical ways for improving the working conditions of female workers are: (i) cooperation between managers, workers, and government officers is regarded as vital for the ergonomics intervention program, (ii) worker participation, (iii) appropriate training course with regard to ergonomics education, and (iv) managerial support
