How to reduce dust when grinding concrete?

It is best to use industrial vacuum cleaners, such as the small industrial vacuum cleaner F-65L produced by our company, the medium and large double cylinder vacuum cleaners IVC-33A, IVC-55A, IVC-55L, etc. Secondly, the prevention and control work in the production process is also a good prevention.
1. Wet cutting (water spray)-this kind of engineering control helps eliminate silica dust in the air, and is the most effective dust control method in concrete cutting and grinding. Portable water tank or trolley. Masons should make a plan before arriving at the job site to ensure the resources and manpower required to successfully carry out the wet cutting project.
2. HEPA vacuum and exhaust ventilation system-Industrial vacuum and exhaust ventilation systems are very useful tools when dust cannot be removed from the source. These systems can absorb the formed dust, which is very beneficial for cleaning the site. A high-efficiency particulate air (HEPA) filter prevents the collected dust from escaping the vacuum system.
3. Training-employees should receive comprehensive training on the hazards of silica dust. Training should cover prevention and control methods, respiratory protective equipment, and cleaning methods after get off work.
4. Wear a mask
According to the layout of the site, masons and construction workers must wear respiratory protective equipment (RPE). Listed below are the three main types of respirators that can be used in the workplace:
Disposable dust mask-can be used in areas where the exposure is up to 5 times that of OSHA PEL.
Half-face dust masks – The safe exposure of half-face dust masks is ten times that of OSHA PEL
Full-face dust masks – Full-face dust masks can protect workers from OSHA PEL damage by 50 times.
