What is Powder?
Particles that are emitted or spread over the workplace are defined as dust.
If the particle size of the solids (particles) in the atmosphere is smaller than 300 microns, they take the name of dust.
Why Should I Make Dust Measurement in My Workplace?
· Reduces the field of view of the employees,
· Causes serious disturbance to employees,
· Reduces business efficiency,
· Causes occupational diseases.
· Occupational diseases (pneumoconiosis), toxic dust, blood circulation through the organism into the case of occupational poisoning, cancer or allergy may occur.
How Often Should I Perform Dust Measurement?
The employer shall carry out the measurement, testing and analysis of occupational hygiene in accordance with the risk assessment. If there is a difference in personal exposures as a requirement of the workplace environment or work, the occupational physician or occupational safety specialist is required to repeat the measurement, testing and analysis of work hygiene.

How is Gravimetric Measurement done?
In this dust measurement, the tool can be sampled continuously for 8 hours. A small pump driven by a battery powered motor absorbs 2.5 liters of air per minute. The dust particles larger than 6 microns collapse to the bottom of the channels. Those smaller than 6 microns are collected on the filter. Empty weighed filter at first
After the sampling process is completed again weighing is taken. The dust concentration in the air is calculated in mg / m from the difference between the difference and the amount of air passing through the instrument which is automatically saved by the instrument. Personal dust measurement and ambient dust measurement should be performed.
Basic Steps in Gravimetric Measurement are as follows:
1. Determination of Species of Powder to be Sampled and Applied
