Risks

Coal dust is a fine powdered form of coal, which is created by the crushing, grinding, or pulverizing of coal. Because of the brittle nature of coal, coal dust can be created during mining, transportation, or by mechanically handling coal.It is a form of fugitive dust.. Grinding coal to dust before combusting it improves the speed and efficiency of burning and makes the coal easier to handle.

DUSTS NOT OTHERWISE SPECIFIED (DUST NOS) AND

(Dust NOS) with an emphasis on recommending a health‐based occupational exposure limit (OEL). Dust exposures are the bane of many industries, none more so than the tunnelling, construction, mineral extraction and processing industries or those handling or working with dry

Occupational dust exposure

Occupational dust exposure can occur in various settings, including agriculture, forestry, and mining.Dust hazards include those that arise from handling grain and cotton, as well as from mining coal. Wood dust, commonly referred to as sawdust, is another occupational dust hazard that can pose a risk to workers' health.. Without proper safety precautions, dust exposure can lead to

Asbestosis and silicosis

Asbestosis and all forms of silicosis can progress even if exposure ceases.6, 23 Both are irreversible; however, some epidemiological and laboratory investigations suggest that early identification of disease followed by withdrawal from exposure may lead to more favourable long-term outcomes. 24 Since the risk of either disease relates largely to the cumulative exposure to respirable hazardous

GRINDING DUSTS OF ALLOYED STEEL AND HARD METAL

Dust particles seem to have the same metallic structure as the ground stainless steel piece. Concentrations of tungsten and cobalt in hard metal grinding dusts were up to 20 and 25%, respectively. An enrichment of cobalt in the airborne dust compared with the base material was also observed.

OCCUPATIONAL EXPOSURE TO WOOD DUST

Occupational exposure to wood dust and biohazards associated with wood dust (endotoxins, (1-3)- β-D-glucans, Gram (-)ve bacteria and fungi), their correlation to respiratory function, and symptoms among woodworkers have been investigated in the present study. Wood dust, endotoxins, and allergenic fungi are the main hazards found in woodworking

Process

As materials such as wood, stone, sand etc. are not covered in REACH, emission such as RCS arising from working on stone, and dust arising from woodworking are not covered. However, if a coating has been applied to the wood, that material may be covered under REACH and potential exposure to it will require some consideration during registration under the life-cycle requirement.
