Recommendation:
Based on the result of this study, the researchers recommend that the quarry industries should be properly examined with working conditions in mind as to ensure improved welfare for the workers. The environmental health and occupational health officers should swing into actions to ensure compliance with standard of work design as majority of the workers reported poorly designed work environment and that was also found to be a major determinant of quality of life. Improved mechanization of some of the work processes especially those involving exposure to vibration and other high risk aspect is highly recommended.
