Working with respirable Crystalline Silica (RCS) Dust

Many Festool users ask what the are the requirements for dust extractors when working with Respirable Crystalline Silica (RCS) / Concrete dust.

We have now received all the facts regarding the requirements for working with this dust class and what end users would need to know when choosing the right dust extractor for working with this dust class.

This is the terminology that Worksafe is now using for the requirements with Respirable Crystalline Silica (RCS) Dust: On-tool dust extraction This is a type of local exhaust ventilation (LEV) which is fitted directly onto the tool.
  • One effective form involves a LEV ‘system’ consisting of several individual parts – the tool, captor hood, dust class M or H extraction unit and tubing.
  • Integrated dust extraction devices are available for some hand-held tools.
These self-contained units are fitted directly onto the tool where they automatically filter and collect dust. You should extract dust from the unit using a dust class M or H vacuum, or empty it directly into a waste bag in a way that does not generate dust when you dispose of it.

Integrated dust extraction devices are only recommended for handheld drills with low air and dust volumes as they do not fall under dust class M or H. As you can see, the minimum requirement would now be an M-Class dust extractor when they work with any form of Respirable Crystalline Silica (RCS) Dust. This is basically for any customer working in the concrete trade whether they are cutting, grinding, or sanding.

At the moment we have no M-Class extractors in our range, however, we have already placed an initial order with Germany for an M-Class extractor in the CT 36 AC version that we will be able to offer to the market. Festool is still seen as the specialist in the dust extraction category and it is important that we offer the right solution for the right application and we are certain that this will cement our reputation as the market leader with regard to dust extraction.
