In order to prevent, control and eradicate occupational diseases might caused by construction projects, to regulate the supervision and management of occupational health of construction projects, and to ensure the prevention facilities of occupational diseases in construction projects go into designing, construction, production and use simultaneously with the main part of the projects, Code of Occupational Disease Prevention of PRC specifies the regulations for the assessment of the occupational diseases in construction projects.

Pre-assessment of Occupational Diseases in Construction Projects

Significance of pre-assessment:
Pre-assessment of occupational diseases aims at the construction projects that might cause occupational diseases. It carries out hygiene analysis and assessment on the occupational-disease-inductive factors and its harmfulness and exposure levels, prevention facilities and emergency rescue facilities of occupational diseases on the stage of the feasibility proof of the projects. 
Assessment on the effects of the control of the occupational diseases in construction projects refers to the comprehensive assessment on the occupational-disease-inductive factors and its exposure levels in the workplace, prevention facilities and measures of occupational diseases and the effects between the completion and the final acceptance of the project. 
Approve and initiate a project: The construction project can get the approval from the administrative department after the pre-assessment of the occupational diseases. 
Forecast the types and intensity of the inductive factors: Forecast the types and intensity of the inductive factors that might exist in the working place after the completion of the project with the methods such as analogy.
Control the occupational diseases from the very beginning: Use professional advice to carry out the prevention work of occupational diseases after the completion of the project so as to avoid the occurrence of occupational diseases.

Test and assessment on the radiological prevention in the workplace

Laws and regulations:
Code of Occupational Disease Prevention of PRC
Article 27 The Employer should appoint respective employee to make routine supervision over occupational-disease-inductive factors and ensure the normal operation of the monitoring systems.
The Employer should make regular test and assessment on the occupational-disease-inductive factors in the workplace according to the regulation of the public health authority under the State Council. The assessment result shall be logged into the Employer’s occupational health archive for regular submission to local public-health authority and for release to the laborers.
The test and assessment of occupational-disease-inductive factors should be undertaken by occupational-health technical service organizations who are approved by the public health authorities under province-above people’s governments. The assessing organization should be objective and justified in the test and assessment.
In the event that the occupational-disease-inductive factors in the workplace fail to comply with the national standard and requirement of occupational health, the Employer should take immediate countermeasures, which, if failing to eradicate the problem, should necessitate immediate discontinuation of the operation concerned. The discontinued operation should not be restored unless the occupational-disease-inductive factor is accredited consistent with the national standard and requirement of occupational health.
Interim Measures for Supervision and Administration of the “Three Simultaneities” for Occupational Health at Construction Projects(Order NO.51 by State Administration of Work Safety)
Article 10 For those construction projects that might cause occupational diseases, the construction organization should entrust the pre-assessment of occupational diseases and the pre-assessment report to occupational health technical service institutions with appropriate qualifications. 
The pre-assessment report should conclude as the following:
(1) Introduction of the project
(2) Analysis and assessment of the occupational-disease-inductive factors and its harmfulness to the health of laborers
(3) Assessment of the types of the occupational diseases in construction projects
(4) Analysis and assessment of the technology intended to be used in the prevention facilities of occupational diseases in construction projects
(5) Advice on the setting up of occupational health management organizations, the personnel allocation of occupational health management and system construction
(6) Advice on the prevention measures of occupational diseases in construction projects
(7) Conclusion of the pre-assessment of occupational diseases
Article 11 After the completion of the pre-assessment report of occupational diseases, the construction organization should arrange related experts on occupational health to evaluate the report.
The construction organization is responsible for the authenticity and legitimacy of the pre-assessment report of occupational diseases.

Article 26 On the test run of the construction project, the construction organization should monitor the operation of prevention facilities of occupational diseases and the occupational-disease-inductive factors in the workplace, and entrust the assessment on the effects of control of occupational diseases to occupational health technical service institutions with appropriate qualifications.
The construction organization should provide with tested place, equipment and facilities qualified to the standards and requirements of test and assessment.
Article 27 After the completion of the assessment report of the effects of control of occupational diseases, the construction organization should arrange related experts on occupational health to evaluate the report.
The construction organization is responsible for the authenticity and legitimacy of the assessment report of the effects of control of occupational diseases.

Monitoring occupational-disease-inductive factors

According to the Code of Occupational Disease Prevention of PRC, “The Employer should make regular test and assessment on the occupational-disease-inductive factors in the workplace according to the regulation of the public health authority under the State Council.” And according to the Article 20 from the Provisions on the Supervision and Administration of Occupational Health at Work Sites, “Employers who can cause serious occupational diseases, shall entrust the occupational health technical service institutions with corresponding qualifications, to conduct one test of occupational-disease-inductive factors at least every three years.” Employers shall, according to rules sand regulations, carry out test and assessment on the workplace, specify the occupational-disease-inductive factors, measure its intensity, analyze its harmfulness to the health of laborers, and assess the effects of prevention of occupational diseases by the employer to give advice on the prevention measures of occupational diseases to the workplace not reaching the standards of prevention of occupational diseases.
Routine observation applies to the regular observation of the intensity of the harmful articles in the air in the workplace.
When the occupational exposure limit was the Permissible Concentration-Time Weighted Average, representative sampling points should be selected. Sample a working group in the working day with the highest harmful substance concentration in the air.
When the occupational exposure limit was short term exposure permissible concentration, limit or highest permissible concentration, representative sampling points should be selected. Sample when the intensity of the harmful substance concentration in the air of a working group is the highest.
