The Mine Safety and Health Administration (MSHA) has released the investigation report on an April 27, 2013, fatality at a surface gypsum operation. The incident involved a 58-year-old mechanic with 2 years of experience who was killed when he was clearing a blockage on a mobile track-mounted crusher and became entangled in the discharge conveyor.
MSHA recommends the following best practices for conveyor work:
Establish policies and procedures for conducting specific tasks on belt conveyors.
Before beginning any work, ensure that persons are task trained and understand the hazards associated with the work to be performed.
Do not perform work on a belt conveyor until the power is off, locked, and tagged, and machinery components are blocked against motion.
Provide emergency stop mechanisms at the control panel(s) and at ground level where maintenance or repair work is performed.
Provide appropriate controls to protect any person working near a stalled conveyor from unexpected motion.
Maintain communications with all persons performing the task. Before starting belt conveyors, ensure that all persons are clear.
