Over the past 24 months MSHA cited this standard 761 times. See how MSHA sets a penalty with the free MSHA penalty calculator.

Citations by month

By issue date. MSHA publishes citations a few days after they are issued, so the current month is still filling in.

About this record

These figures come from public Mine Safety and Health Administration (MSHA) open government data on mines, inspections, violations and assessed violations. MineCitation copies them as published and does not add findings of its own.

A citation records a condition an MSHA inspector found. Operators can contest citations and penalties, and amounts can change after review. MineCitation is not legal advice.
