DUST IS PARTICLES OF A
MATERIAL RANGING FROM
1 TO 1000 MICRONS
*
IN SIZE
DUST IS CREATED BY
WORKING WITH MATERIALS
ON THE FOLLOWING TASKS:
DUST HAS TWO SIZE CLASSIFICATIONS
Total inhalable dust (up to 100 microns). This can be inhaled into the respiratory tract.
Respirable dust (up to 10 microns). This is normally invisible in standard light and can remain
airborne for up to 8 hours. Because of its weight and size it can be inhaled right into the lungs
where the oxygen is processed.
THERE ARE THREE MAIN TYPES OF CONSTRUCTION DUST
Silica dust (Respirable Crystalline Silica or RCS) comes from materials containing silica
such as sandstone, concrete and mortar.
Wood dust comes from wood and wood-based products like MDF and plywood. Wood based
products can be more dangerous because they contain other elements like glue, etc...
Lower toxicity dusts come from materials containing very little or no silica such as dolomite,
plasterboard and marble.
