Dust Measurement

Dust Measurement

Ibn Sina, a philosopher of philosophy, mathematics, astronomy, has a vision: if there were no dust and fumes, people could live for hundreds of years. In other words, dusts are harmful to human health. In terms of scientific definition, powders are tiny particles, 300 microns or smaller in size, bearing the chemical and physical properties of the constituent material, which can remain suspended in the air for a long time.

The properties of powders can be explained as follows:

  • Dust with a size between 300 and 100 microns cannot be suspended in air for a long time and collapses on a surface. It is unlikely that these dusts enter the human body.
  • Dust with a size between 100 and 50 microns can be seen with the naked eye under strong light. Although inhaled by humans, they are most commonly retained in the upper respiratory tract and cannot easily enter the respiratory system.
  • Dust with a size between 50 and 5 microns can also be trapped in the upper airways and accumulate in a humid environment. Depending on the type of dust they may cause some upper respiratory diseases.
  • Dusts of size between 5 and 0,5 microns can reach the lungs and accumulate in the alveoli. They are very harmful and dangerous dusts for the health of employees.
  • Dusts smaller in size than 0,5 microns are not harmful to the body and can enter and exit the lungs.

In short, the most dangerous dusts for human health are those with a size between 5 and 0,5 microns.

During production activities, operations such as digging, drilling, crushing, cutting or shredding cause dust. In addition, many hot processes are sources of dust. Dust, which forms with the heat, is released together with the smoke, if adequate and appropriate precautions are not taken. Dust is also emitted into the air when discharging, transporting, storing or using in powdered or dusty raw materials or semi-processed materials.

Dust that is invisible to the eye and has a long suspended time are the most respirable dusts and have a high risk of causing disease in the lungs.

Our organization From ÖSAS Accreditation Agency, Based on the accreditation authority it receives in accordance with TS EN ISO / IEC 17025 standard, it performs dust measurements within the scope of environmental analysis.
