How Often Should OHS Measurements and Analyzes Be Performed?

OHS, that is, "Occupational Health and Safety", can be defined as all practices aimed at protecting occupational and worker health within the scope of relevant laws and regulations. In order to determine whether a working environment is suitable for employees, OHS measurements are carried out at certain intervals.

Within the scope of "TS EN 689: Workplace air - Guideline for comparing chemical substances exposed to inhalation with limit values and evaluating the measurement strategy", measurements should be carried out at periodic intervals in a workplace.

The frequency of the period is determined according to the study areas, considering the operation cycles, control error results, closeness to the limit values, the effectiveness of the process controls, the time required to restore control, and the changes in the results obtained over time.

The exposure value is important in periodic measurements. Situations that may change the evaluation conditions such as ventilation systems, organizational changes, capacity changes may occur.

In general, we can talk about a period system as follows.

G.O or A.O<0.1* Exposure Value - Every 36 Months
0.1* Exposure Value< G.O or A.O<0.25* Exposure Value - Every 24 Months
0.25* Exposure Value< G.O or A.O<0.5* Exposure Value - Every 18 Months
0.5* Exposure Value< G.O or A.O - Every 12 Months

OHS measurements should be carried out regularly in the workplaces, taking into account the values mentioned above.
