Internal measurements in the workplaces are carried out in order to determine the physical and chemical effects arising from the operational activity and in the working atmosphere. At the end of these measurements, the risk areas of the work environment are determined and the risk level of the environment is determined. In this way, it enables the determination of the measures to be taken by the management of the workplace.

Breathable dust measurements are carried out among numerous measurements such as noise measurement, vibration measurement, chemical measurement, lighting measurement, thermal comfort measurement, volatile organic compound measurements, chemical gas and vapor measurement.

Dusts suspended in air are technically called particulate matter, PM. The lengths of these particles are measured in microns (one micron is one millionth of a meter in length).

Working environments are usually closed environments. In many studies, it has been found that air pollution increases due to particles and this causes respiratory diseases in workers and serious diseases resulting in death.

According to the classifications, particles smaller than 0.1 microns in diameter are defined as very fine particles, particles of 0.1 microns to 2,5 microns are fine, particles between 2.5 microns and 10 microns are coarse and particles larger than 10 microns are coarse particles. Coarse particles are formed mainly by mechanical processes, while fine and very fine particles are mixed with the combustion of diesel fuels or emitted into the air as a result of chemical reactions of gases.

Accredited laboratories also perform ambient dust measurements within the framework of indoor measurements. These laboratories have state-of-the-art test and measurement devices and experienced and trained staff to take quality, reliable and fast results and take into consideration many standards published by local and foreign organizations during their studies.
