About this data

About Mangilao OSHA records

Every record on this page is sourced from the U.S. Occupational Safety and Health Administration (OSHA) enforcement dataset, published by the Department of Labor and updated daily. Mangilao appears in the dataset because at least one establishment in the city has been inspected by federal or state-plan OSHA inspectors in the past five years.

What an inspection means. OSHA inspections can be triggered by a worker complaint, a reported accident, a referral from another agency, or as part of a programmed targeting campaign for high-hazard industries. An inspection on record does not necessarily mean violations were found — many inspections close with no citations.

How to read a citation. Citations are classified as Willful, Serious, Repeat, or Other-than-serious. The dollar penalty next to an employer is the initial proposed penalty; the final settled amount is often lower after the abatement process. For context on each classification, see our explainer on willful vs. serious vs. repeat OSHA violations.
