Ergonomic Appraisal of Blasting Activities at Majan Limestone Quarry

Raleke Ralus Okeke

This study explored the ergonomics associated with blasting activities at Majan Limestone quarry. The remoteness, altitude and severe weather conditions made blasting activities unwieldy, prompting the need for a leeway to augment the stress and discomfort associated with it. Consultations were made with the blasting crew with detailed explanations as regards the need for an ergonomic evaluation. A risk factor report card was created and issued out to the blasting crew. Manual tasks associated with blasting were observed, while work place records were reviewed. During the study, some ergonomic interventions were introduced to ameliorate the stress and reduce the exposure to risk factors; the improvements were noted with some recommendations. Other quarries or mines with similar working conditions may find the recommendations useful.
