CA SB1303

Expands criminal liability under Penal Code Section 387 by changing "knowingly fails" to "fails" to take appropriate action regarding serious concealed dangers, making the offense easier to prosecute.

Requires corporations, limited liability companies, and managers to notify appropriate government agencies in writing about concealed dangers, in addition to existing notification requirements to the Division of Occupational Safety and Health.

Mandates warnings be provided to both affected employees and "other potential victims" of serious concealed dangers, with warnings to the general public permitted through publication if specific victims cannot be identified.

Increases the maximum fine for corporations and limited liability companies from $1,000,000 to $2,500,000 for violations.

Expands the list of "appropriate government agencies" with regulatory authority to include the Public Utilities Commission, Geologic Energy Management Division, and California Underground Facilities Safe Excavation Board.
