B.6 Cleaning work under the main crusher
Nature of work:
The main crusher is cleaned at two stages. First, when quarry dust is collected during crushing from
the pit below and the second to remove the falling and struck boulders from the pit below the main
crusher. While collecting the dust from below the crusher, the workers are exposed to the highest and
most hazardous concentrations of dust. Often women conduct this activity.
Risk Factors:
− Musculoskeletal Disorders (MSD) and back pain due to working in confined spaces and having
little room for safe lifting
− Over exertion while lifting without proper hand protection may result in hand and leg injuries
−
−
MSD due to the constant bending and lifting of the women workers
Low lighting due to the location and to dust formation may cause disturbance in vision, eye
disorders, pulmonary diseases, and other injuries
