When MSHA conducted special impact inspections at 20 mines in September, the agency uncovered safety concerns that included accumulations of combustible dust, an open and unsupported excavation hole, nonworking self-contained self-rescuer units, inadequate pre-shift examinations, inadequate testing of electrical grounding systems and more. The inspections resulted in a spate of citations, orders and safeguards against the mines.
Special impact inspections target mines that MSHA deems are in need of �increased agency attention and enforcement� due to poor compliance history or compliance concerns. MSHA began conducting these inspections in April 2010 in the wake of the deadly Upper Big Branch Mine explosion.
