In accordance with the Occupational Health and Safety Act, which was enacted in 2012, employers are responsible for occupational health and safety in terms of occupational health and safety. Conducting these studies depends on the results of the risk assessment of the work environment and activities. Depending on the differences in the working environment or the requirements of the work, these studies should be repeated at regular intervals.

Based on this law, the following legal regulations were also issued in 2013:

• Implementing Regulation on Protection of Employees from Noise-Related Risks
• Dust Fighting Regulation
• Implementing Regulation on Health and Safety Measures for Working with Chemical Substances

In general, accredited testing and inspection laboratories conduct measurements and tests such as dust measurement, noise measurement, vibration measurement, chemical measurement, lighting measurement, thermal comfort measurement and VOC measurements in the working environment. In addition, measurements of noise exposure, measurement of vibration exposure, measurement of gas exposure, measurement of dust exposure, measurement of dust exposure, measurement of respirable total dust and measurement of VOC (chemical) exposure are also carried out to determine the personal exposure of employees.

With these measurements, employers protect the employees from the risks and harmful consequences of the materials and working conditions in the working environment or used in some way. Businesses must have these tests on the chemical, physical and biological factors related to the working environment, testing, analysis and evaluation in an authorized testing and inspection laboratory. Reports issued at the end of the studies must be kept in order to be shown in internal and external audits.

Competent laboratories are obliged to comply with the principles of the legal regulations in force in the test and measurement studies, as well as the standards that are directed by local and foreign organizations.

According to the legal regulations, it should be decided by the occupational safety specialist or the workplace doctor in the team, or in the enterprise, whether the environmental measurements and personal exposure measurements should be made. However, these measurements should be done once a year in general. In addition, occupational hygiene measurements should be carried out not only to pass formal inspections, but also to determine the conditions of the work environment and the effects of the work environment on the employees and to analyze their possible effects. If the measurement results are above the limit values ​​shown in the relevant legal regulations and standards, technical measures should be taken immediately and these measurements must be rebuilt. In the meantime, if there is a change in working environment conditions, it is necessary to repeat the measurements without waiting periodically. Moreover, the risk assessment study should be revised and periodic periods should be determined again.

In accordance with the legal regulations, the monitoring of the working environment and the health status of the employees should be recorded and the results should be explained to the employer together with the annual evaluation report.

The main tests carried out within the scope of ambient measurements are:

• Air microbiology tests
• Wind force measurements
• Ventilation tests
• Chemical exposure tests
• Vibration exposure measurements
• Lighting measurements
• Thermal comfort measurements
• Safety tests
