The Hoover Dam power plant outside of Las Vegas was cited for a total of 58 safety and health violations, including fall and electrical hazards, as well as lead and chemical exposure.
According to the Occupational Safety and Health Administration, eight of the 58 alleged citations were repeated offenses.
OSHA specifically cited the Hoover Dam Hydroelectric Power Plant for lack of required guards on machinery, inadequate protective equipment and failure to properly maintain and inspect firefighting equipment, among others.
OSHA announced the violations Monday, more than two years since its previous inspection of Hoover Dam in October, 2010.
"We are concerned to have found this number of serious safety and health violations at the Hoover Dam plant," said Ken Atha, OSHA's regional administrator in San Francisco. "We expect to work closely with the agency to rectify these deficiencies and provide a safe and healthful work environment for employees."
In response, the Bureau of Reclamation, which operates the facility, said it is taking "aggressive steps" to correct the violations.
"Although one violation is one too many, we are taking the necessary steps to ensure the issues raised are fixed and do not happen again," said Lower Colorado Regional Director Terry Fulp. "We are committed to the safety of all the employees who work in our facilities, the visitors who enjoy the Hoover Dam experience and the general public."
The Bureau also noted none of the items related to the violations posed any safety danger to the public or threatened the structure of the dam.
The Bureau said it elected to meet informally with OSHA to discuss the violations and to continue ongoing remediation of outstanding issues.
