Prevention of silicosis from stone and quartz cutting

1 Feb 2022

Silicosis prevention is essential, but what is silicosis?

Silicosis is pneumoconiosis caused by inhalation of silica molecules. Pneumoconiosis is understood to be the disease caused by a deposit of dust in the lungs with a pathological reaction against it.

Silicosis prevention: how to avoid it and what are its problems

Granite and Silestone Silicosis

The increasing increase in silicosis cases is of increasing concern. Since it generates an important problem in the stone sector. It is very common to find companies that do not take any type of measure for the necessary prevention and protection. Of workers who are exposed daily to this risk to their health, silica dust. Which is generated by cutting granite or even quartz agglomerate, such as Silestone among other brands. Maser continues with the awareness and prevention campaign to eradicate this disease that increasingly affects a greater number of workers


European Union legislation on silicosis and how it affects Spain

The EU recognized the carcinogenicity of free silica dust. This means that it has been incorporated into the Directive on occupational protection to exposure to carcinogenic substances, such as silica. Thanks to the European Union, since January it has been considered a carcinogenic substance in Spain.

The limit has been set at 0.05 mg / m3, although until December 31 of this year (2021) there is a transitional provision for 0.1 mg / m3 to be applied. In work centers and workshops, hygiene and separation of areas should be reinforced as much as possible.

How can we do to have a good prevention against silicosis?

The awareness of the employer and the workers is the first step to stop the appearance of cases of the disease. Some measures recommended by the Guide for risk control due to exposure to CRYSTAL RESPIRABLE SILICA, prepared by the Ministry of Industry and the INS, would be:

  1. The protection.
  2. Machinery maintenance.
  3. The incorporation of new tools and equipment.

Maser With its almost half a century of experience in the sector, it is at the forefront of the latest technology. Offering resources to facilitate daily work, as well as promoting awareness measures among companies in the sector. Over the last few years, we have introduced a new range of products to the market. Among them, those that allow the aspiration and filtering of dust stand out.



The dust extraction and filtering cabinets are the best system to avoid breathing silica dust when working with natural stone. As well as quartz agglomerates (Silestone silicosis, produced by the silica that it emits when it is worked) or other types of materials. For this reason, at MASER we present the dust extraction and filtering cabin.

The vacuum center ranges from 2 meters to 6 meters. In addition, it has a special Teflon polyester filter system. Which drastically reduces the need for maintenance. Allowing even use with water without any risk of deterioration.

Four linear filter filters are included in this cabin, guaranteeing 99.8% efficient filtration, fully respecting European and international standards. The use of cartridge filters, instead of traditional sleeves, guarantees a larger filter surface area and therefore less maintenance.

Polyethylene cartridge filters (instead of traditional paper) guarantee a longer life cycle, greater resistance and less maintenance.

Regarding the cleaning cycle of the cartridges, it is carried out by means of a compressed air blowing process, frequently called a cyclone, collected in a 19-liter tank per linear meter installed at the back of the suction cabin and controlled by specific electrovalves. .

In addition, the pressure and frequency of the air backwash can be regulated by a digital cyclic timer with built-in differential pressure gauge.

At this time the filtered air comes out through the upper side of the suction cabin, pushed by the fans present in the same cabin.


On the other hand, the machine for special filter maintenance can be accessed through front and rear panels. These being easily removable.

On request, you can put a front drawer (fixed or mobile) of different dimensions, in Plexiglas, in steel or in acoustically absorbent panels. Allowing the person who uses it to work even at a moderate distance, improving aspiration in the work area.

The differences that exist with respect to the traditional dry cabins on the market:

  • Greater filtering surface. Which implies less maintenance. Avoiding a continuous change of filters and a continuous production of solid waste.
  • Better quality of filter material.
  • Greater amount of air available in the backwash. For a more efficient filter cleaning process. Thus guaranteeing a further extension of its life cycle.
  • The only dry suction machine on the market in stainless steel.



The dust and water suction cabin that we offer at MASER are made entirely of premium quality stainless steel, certified Outokumpu, with folding pressing and laser cutting.prevención de la silicosis, polvo, polvo de silicosis, silicosis, la silicosis, piedra natural, maquinaria para piedra, marmol, piedra natural, granito, 6

Thus ensuring a longer duration in time, a higher general quality and therefore a lower devaluation of the machine over the years.

The operation and use of the system of our dust extraction booth with water is the MODULBOX. This foresees that the operator works in front of the module behind the water curtain and the linear suction slot.

The dust that is produced while we work is sucked in by means of fans, through the slot between the tank and the water curtain.

Initially part of this dust is eliminated by the external water curtain, while the rest is stopped by a water nebulization system, located inside the system.


On the other hand, this cabin has unique characteristics. What make it a very good product for the prevention of silicosis:

  • The module also has high quality honeycomb PVC drop separator panels (without straw or similar material). Which comply with the CTI136 and ASTM E-84 regulations for self-extinguishing and suitable for separating water from the exhaust air. Reducing the environmental impact, saving water and avoiding bacterial proliferation phenomena.
  • These panels can be easily removed from the front. No need for the operator to climb onto the roof of the machine and uncomfortably enter from the top for routine maintenance.
  • The purified air comes out through the upper part of the machine. Allowing its recirculation in the environment.
  • The dust thus eliminated is collected in the underlying inclined tank, with adequate capacity, turning into sludge and thus avoiding any possibility of air-dispersion in the environment. Thanks to its particular inclination, the tank reduces maintenance operations by the operator to a minimum.
  • The water present in the system is recirculated. Always through a submerged pump with a stainless steel pump body and rotor.


What are the other solutions proposed by MASER for the prevention of occupational silicosis?

The awareness and prevention campaign for the eradication of silicosis. It is being carried out through MASER to convey to our clients, through our communication and commercial network, the importance of adapting their businesses. As well as the necessary incorporation of new tools, such as pneumatic manual machines, which do not involve a large outlay and guarantee the best results.

It is important to create routines. As well as controlling its application to guarantee the performance of daily tasks in safe conditions from exposure to silica dust. Examples of these are:

  • Check the correct operation of the prevention systems (supply of humidity, aspirations, etc.). This step is prior to the start of the activity that generates dust in suspension (drilling, use of hammers, pouring and transferring materials, sawing and cutting, etc.).
  • Good practices for operators when leaving the cabins (of mobile machinery or fixed installations).
  • Instructions or authorizations for specific jobs with high exposure to dust. This can occur with certain cleaning and maintenance tasks. For example, filters or capture equipment. And it is that the maintenance of the equipment is thought to guarantee its adequate functioning during its use and avoid exposure to dust.
