Chiselling + non-power tools
Smaller, non-power tools such as chisels can generate high levels of respirable dust, such as silica, in stone works. A vital job for creating features and designs within stone, this process requires chipping and breaking down part of the stone into fine dust as a byproduct, which becomes airborne and poses significant risk to workers.
CNC machines
CNC machines use a computerised operation to cut and shape large slabs of marble and other materials in stone works, often generating dust as a byproduct. Without proper dust control measures, such as water to damp down the dust or dust extraction units added on the machine, it can become airborne and easily inhalable.
Handheld power tools
Dust can be generated from handheld drills, grinders and other power tools used in stone works. The high intensity from the automation of these tools means stones are ground and broken down faster, leading to higher levels of airborne dust, especially in and around the breathing zone of those using the power tools.
Lack of water-controlled processes
It’s not just on CNC machinery where water-controlled processes are essential to limiting dust control. Any large machinery jobs involving polishing, cutting and finishing generates high levels of respirable dust which, and without effective water-control to dampen the dust making it heavier, dust subsequently becomes airborne.
Ineffective maintenance processes
As there are various different ways respirable dust can be generated in stone work industries, it’s essential that maintenance is as effective in relation to the workplace you’re in to prevent further dust generation. Dry sweeping, lack of dust extraction and general ignorance of the issue can lead to dormant dust not being dealt with properly.
