1. In the Official Gazette dated 05.11.2013 and numbered 28812, the Dust Fighting Regulation was published.

2. Workplaces covered by the Occupational Health and Safety Law No. 6331 dated 20.6.2012; It is applied in cases where dust exposure may occur due to the work of the employees.

6331 in the OSH convention; the establishment of a dust fighting unit has become mandatory.

3. The employer shall carry out dust measurements according to the Regulation on Labor Hygiene Measurement, Testing and Analysis Laboratories published in the Official Gazette dated 20.8.2013 and numbered 28741 in the workplaces where all kinds of dust occur.

4. The employer is obliged to carry out a risk assessment in accordance with the provisions of the Occupational Health and Safety Law No. 6331 and the Occupational Health and Safety Risk Assessment Regulation published in the Official Gazette dated 29.12.2012 and numbered 28512.

5.

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.

Where can the dust be measured?

Mining, Foundry and other metallurgical activities, Shipbuilding, Production of glass, ceramics, stone objects, Chemical and pharmaceutical industries, Agriculture Food industry, Wood industry

Which procedures may cause more dust exposure?

Cutting, sanding, grinding, machining, polishing, sandblasting etc. mechanical operations

How can we classify powders?

1. Fibrogenic Powders

2. Carcinogenic Powders

3. Toxic Powders

4. Radioactive Powders

5. Explosive Powders

6. Less harmful powders

Fibrogenic Powders (which are harmful to the respiratory system); Silica (quartz), Silicates (asbestos, talc, mica), Beryllium Ore, Tin Ore, Some iron ores, Coal (anthracite, bituminous coal)

Carcinogenic Powders; Radium, Asbestos

Toxic Powders (toxic effect on organs and tissues); Beryllium, Arsenic, Lead, Uranium, Radium, Antimony, Manganese, Tungsten, Nickel, Silver ores

Radioactive Powders (those harmful to α and β rays); Uranium, Radium, Thorium ores

Explosive Powders (combustible when suspended in air); Metallic Powders (magnesium, aluminum, zinc, tin, iron), Coal (Bituminous coal and lignite), Pyrite ore, Organic powders, Less harmful powders, Gypsum, Kaolin, Limestone

What are the basic instruments used in dust measurement?

· Clamp

· Filtered tools

· Gravimetry

· Thermal precipitator

· Tindalometer

· Electrostatic Precipitator

· Radiation Detector

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
