Vibration Measurement

Are There Legal Regulations Concerning Vibration Measurement?

On August 22, 2013, the Ministry of Labor and Social Security issued a Regulation on the Protection of Employees from the Risks Related to VIBRATION of 28743.

It is based on the Article 30 of the Occupational Health and Safety Law No. 6331 dated 20 June 2012.

Prepared in parallel with the Directive 2002/44 / EC of the European Parliament and of the Council of 25 June 2002.

Measurements are made according to the Regulation on Labor Hygiene Measurement, Testing and Analysis Laboratories published in the Official Gazette No. 28741 dated August 20, 2013.


Vibration; vibrations and oscillating movements of vehicles, equipment and machines. Vibration is expressed by two physical variables. These are frequency and violence.

The frequency of vibration; The number of vibrations per unit time is called the frequency of vibration. The unit is Hertz (Hz).

Vibration Intensity; In the environment where the vibration occurs, it is called the intensity of the vibration in the unit area, in the unit area, the current power perpendicular to the direction of motion of the energy coming from the vibration. The unit is (W / cm2).

Whole body vibration:; When transferred to the entire body, there is a risk for the health and safety of the employee, especially the discomfort in the lumbar region and the mechanical vibration that causes trauma to the spine.

Hand-arm vibration; When transferred to the hand-arm system in the human, it is a mechanical vibration that poses a risk for the health and safety of the worker and, in particular, leads to disorders of the arteries, bones, joints, nerves and muscles.

Exposure action value; In case of exceedance, it is the value that requires the control of the risks arising from the exposure of the employee to the vibration.

Exposure limit value; It is the value that employees should never be exposed to a vibration on the value.

Where does Vibration Stimulate Most?

1. Stone crushers,

2. pneumatic hammers used in coal and mining,

3. portable saws used in forestry,

4. polishing and grating machines,

5. Power tools used in industry.

6. The use of tractor and truck,

7.Woven looms,

8. Road construction, maintenance and repair machines

9. machines and machines in steel structures

What are the effects of vibration?

· Causes continuous noise.

· It affects performance.

· Devices may be damaged by vibration.

· Wearing may occur.

· Continuous headache.

· Permanent vibrations in the eyeball.

· Far away vision loss is experienced.

· There are general equilibrium disorders.

· Hardness of the back and neck muscles.

· Causes problems such as digestive system disorders.

· It can show harmful and lasting effects in the sensory organs (in the muscles, ligaments and joint sensing systems), in the inner ear equilibrium organ, in the sensitive and subcutaneous organs of the skin, in the lower and upper capillary network.

What are the exposure values ??for hand-arm vibration?

Daily exposure limit value for eight hours working time: 5 m / s2

The daily exposure action value for an eight-hour working time: 2.5 m / s2

What are the exposure values ??for whole body vibration?

Daily exposure limit value for eight hours working time: 1,15 m / s2

Daily exposure action value for eight hours working time: 0.5 m / s2

Obligation as Employer?

1. The employer deals with the level of mechanical vibration that employees are exposed to in the risk assessment carried out at the workplace.

2. The employer determines the exposure to mechanical vibration by performing measurements.

3. Keeps the results of the evaluation and measurement in an appropriate way to be used when required and displayed in audits.

4. Prepares exposure action plan.

5. The employer shall work on prevention or reduction of exposure.

6. İşvren shall immediately take the necessary measures to reduce the exposure below the exposure limit value.

7. The employer identifies the reasons for exceeding the exposure limit value and takes the necessary measures for protection and prevention to prevent its repetition.

8. Ensures that employees receive information and training.

9. The employer receives the opinions of the employees or their representatives and ensures their participation.

10. The employer ensures that employees are subject to health surveillance.

11. The employer takes the necessary protective measures, taking into account the results of the health surveillance.

12. Ensures the implementation of a regular health surveillance to review the health status of employees.

What to Consider While Risk Assessment?

· Type, level and duration of exposure including intermittent vibration or exposure to repeated shocks,

· Exposure limit values ??and exposure action values,

· The impact on health and safety of all employees, including women employees and private policy groups,

· The indirect impact of mechanical interactions between mechanical vibration and work environment or interactions between mechanical vibration and other work equipment on the health and safety of employees,

· The level of mechanical vibration of work equipment
