Why Is Dust-Free Flooring Removal & Concrete Grinding So Important?

Silica dust is harmful when inhaled into your lungs. As it is 100 times smaller than a grain of sand, you can be breathing it in without knowing. Exposure to silica dust can lead to the development of lung cancer, silicosis (irreversible scarring and stiffening of the lungs), kidney disease, and chronic obstructive pulmonary disease. It is estimated that 230 people develop lung cancer each year as a result of past exposure to silica dust at work.

Silica dust particles become trapped in lung tissue causing inflammation and scarring. The particles also reduce the lungs’ ability to take in oxygen. This condition is called silicosis. Silicosis results in permanent lung damage and is a progressive, debilitating, and sometimes fatal disease. This is why we provide Dust-Free Flooring Removal & Concrete Grinding services.

Being Safe With Concrete Dust
Concrete Dust is an inevitable by-product of the concrete cutting and grinding process. Saws, drills, and grinders make their way through concrete creating fine particles of silica. When inhaled, these fine particles can cause irreparable damage to the lungs. Preventative measures need to be put in place when undertaking any form of concrete cutting or concrete grinding to reduce the risk of long-term health complications.

What Is In Concrete Dust?
Silicon is the second most common element on Earth after oxygen. It is contained in most rocks, sand, soil, and plaster. Concrete, therefore, contains a good amount of silicon. When silicon is cut, crushed, drilled, or ground it can produce silicon dioxide, often known as silica (respirable crystalline silica) better known as concrete dust.

Why Is Concrete Dust Harmful To Humans?
When silica (concrete dust) is inhaled it gets trapped in the lungs as the particles are so fine. The trapped particles set off a bit of a chain reaction in the lungs as the body attempts to fight off these foreign deposits of dust. Prolonged or intense exposure to concrete dust can cause fibrosis of the lung making breathing difficult, reducing the quality of life and in some cases death.

How Can Concrete Dust Be Avoided In The Concrete Industry?
There are a number of methods to reduce the creation of concrete dust which reduces the risk of exposure when working with concrete, we will list the methods below.

Respiratory Equipment
Specialised Dust Masks are to be used in addition to either dust extraction equipment or water suppression safety methods. Respirators should meet minimum workplace safety standards and also be fitted correctly.
Class P1 particulate filters are used against mechanically generated particulates e.g. silica and wood dust.
Class P2 particulate filters are used for protection against mechanically and thermally generated particulates.

Dust Extraction
A specialist high-powered M-Class dust extractor is fitted to the saw or tool to vacuum up the dust at the point of cutting, drilling, or grinding. It is important to ensure the dust extractor is designed for the tool being used to it can effectively capture all the dust from the cutting, drilling, or grinding surface. The dust is collected in a bag that can be safely disposed of later.

Water Suppression
Water suppression creates a wet cutting, grinding, or drilling area so that the creation of dust is prevented during the cutting, drilling, or grinding process. It is important to have a continuous flow of water during the process and the right equipment or conditions to cope with water containment and concrete slag and slurry runoff on the worksite.

What Are The Limitations Of Dust-Free Floor Removal? 

When we are completely stripping out a flooring system, substantial dust is produced from removing the flooring system. This dust is still massively reduced by about 90 – 99.99% by connecting our HEPA Dust Extractor – DustMaster DM-2680-M Dust Extractor System to our Hilti TE DRS-B Dust Removal System which is connected to our Hilti TE-2000 AVR Demolition Hammers on all of our jobs. But unfortunately, small amounts of dust are still produced and cannot be completely eliminated.

We will remove all residues on your concrete slab, such as tile glue, magnesite residue, epoxy, waterproofing, stencil concrete, ETC with the use of a high-powered Concrete Grinder that is connected directly to a high-powered HEPA Dust Extractor DustMaster DM-2680-M Dust Extractor System.

When we are removing a flooring system such as tiles or magnesite flooring small amounts of dust is produced from removing the flooring system. There is a chance that around 0.1 – 10% of the dust may escape. Even with the use of high-powered dust extractors connected directly to our jackhammers.

What Are The Limitations Of Dust-Free Concrete Grinding? 

Huge amounts of dust are produced when Concrete Grinding occurs. This is why here at Carpet Removal Sydney we have invested in a high-end HEPA Dust Extractors DustMaster DM-2680-M Dust Extractor System to connect directly to our high-powered Concrete Grinders and Hilti DG 150 Concrete Hand Grinders.

This allows us to provide our clients with a 99.99% Dust-Free Concrete Grinding and Hand Grinding experience while removing thin-set glue, tile grout, paint, glue residue, cement residue, magnesite residue, waterproofing membranes, epoxy coatings, stencil concrete, stamped concrete, spraycrete or any other coating on a concrete slab.

Tile Removal Sydney (Transparent 2)DustMaster DM-2680-H Dust Extractor (Dust-Free) Concrete Grinding Sydney

Dustmaster® series dust extractors have been specially designed to handle the demands of the concrete grinding industry which has high-loading fine dust.

This is the H-Class (often referred to as HEPA) Dust extractor that is certified to handle hazardous dust. These amazing dust collectors have been certified to capture up to 99.99% of the dust.

Dust extraction in our industry is often more important than the actual grinding itself. Without it, we could breathe fine dust which could be detrimental to our health.

– Featuring dual 10A motors, maximum performance is ensured. The longopac bagging system makes handling and disposal of hazardous dust much easier.

– Performance is maintained by the rotary filter cleaning mechanism which automatically cleans the filter during operation.

– This machine has a single durable toggle switch for each motor.

– A deep clean is achieved while running whilst the motor is turned off. The rotary filter cleaning can be turned off when the DustMaster is not in use, using the rotary switch on the front panel.

H-Class (H13) dust extractors must pass the 0.3µm DOP test that certifies they capture no less than 99.99% of the dust.

– The rotary filter cleaning system is very effective and takes only 10-20 seconds to deep clean the filter. You may never have to remove the filter to clean it again, keeping your job and your hand’s cleaner!

– You won’t find a better piece of equipment to handle your job, this is the most high-end piece of equipment that we can use for your job. The next level up would require a 15A power supply which would require you to supply us with a generator on-site as residential power only has 10A.
