What are the three simultaneities of safety production law three?

Legal subjectivity:

Safety production law 3 refers to the safety facilities of a construction project, which must be designed, constructed, put into production and used simultaneously with the main project. Construction units should adhere to the principle of "three simultaneities", and production and business units should provide workers with labor safety and health facilities that meet the requirements of the state, so as to better protect the health and safety of workers in the labor process.

Legal objectivity:

"Environmental Protection Law" Article 41 Facilities for pollution prevention and control in construction projects shall be designed, constructed and put into operation simultaneously with the main project. Facilities for the prevention and control of pollution shall meet the requirements of the approved environmental impact assessment documents, and shall not be dismantled or left idle without authorization.
