Three Simultaneities in Safety

1Safety pre evaluation and assessment

Applicable projectsHigh risk projects such as non coal mines, hazardous chemical production/storage, metal smelting, and chemical engineering (using hazardous chemicals).

• Identification of hazardous and harmful factorsAnalyze the inherent hazards of the project (such as explosions, poisoning, and collapses) and their impact on the surrounding environment and residents.

  
  

• Safety condition demonstration：

• Whether the safety distance between the project and surrounding facilities meets the standards (such as the "Safety Distance Standards for Hazardous Chemicals");

• Assessment of the impact of natural conditions (earthquakes, floods) on safety production.

• 
  

• Suggestions for countermeasuresBased on the pre evaluation report, propose a safety facility design framework to ensure compliance with national standards (such as GB/T 28001) or industry norms.
  output fileThe Safety Pre evaluation Report shall be prepared by a qualified safety evaluation institution.

IIEvaluation of Safety Facility Design


Evaluation focus：

responsible entityConstruction unit, supervision unit, and construction unit.

• Construction plan review：High risk projects (such as deep excavations and blasting) require the preparation of a special construction plan and safety verification; The supervisory unit shall verify whether it complies with the Mandatory Standards for Engineering Construction.

• hidden danger rectificationThe construction unit shall immediately stop work and rectify any design defects or potential accidents discovered.

• Supervision responsibilityFor construction units that refuse to rectify, the supervisor must report to the competent department.

• 
  

4Safety acceptance evaluation and assessment




• Trial operation managementHigh risk project trial operation ≥ 30 days (maximum ≤ 180 days), and hazardous chemical projects need to file a trial operation plan in advance.

• 
  

• Acceptance evaluation content：

• Whether the safety facilities are constructed and operated effectively according to the design;

• The acceptance evaluation report should have clear conclusions and a closed loop for rectifying problems.

• 
  Acceptance Criteria：

5Trial operation and completion acceptance management evaluation

• The effectiveness of safety facility linkage (such as fire protection systems, emergency evacuation routes);

• Establishment of safety production management organization and personnel training records.

• 
  Regulatory verification：

• Verify the authenticity of acceptance through written review or on-site inspection (requiring 2 or more regulatory personnel).

• 
  

VIAssessment of occupational disease prevention facilities' three simultaneities'

• Occupational disease prevention facilities need to be promoted synchronously with safety facilities;

• Consolidating evaluation reports can reduce duplicate reviews (such as merging pre evaluation and control effectiveness evaluation).

• 
  Special evaluation content：

1. Not executing 'three simultaneities'Order to suspend work+set a deadline for correction, and impose a fine of 500000 to 1 million yuan for overdue payment;

2. Fake evaluation reportRevoke the institution's qualifications and impose a fine of 2-5 times the illegal gains;

3. The safety facilities have not been accepted and put into operationPunish according to the Safety Production Law.

Evaluation Type	High risk projects(Mines, hazardous chemicals, etc.)	General Project
safety pre-evaluation	Mandatory implementation, report to the emergency department for review	Comprehensive analysis report on safety production conditions for future reference
Facility Design	Departmental approval (within 20 working days)	Enterprise self review and filing
completion acceptance	Compulsory acceptance evaluation+departmental spot checks	Enterprise self inspection+report formation
occupational disease prevention	All three types of projects need to be carried out, with key supervision for projects that pose serious risks




Key points of implementationEnterprises need to establish a "three simultaneities" full process file for future reference; when changes are involved, re evaluation is required to avoid a decrease in safety performance due to design adjustments. Through standardized evaluation processes, design defects and regulatory risks can be systematically avoided to ensure the intrinsic safety of the project.
