Unfortunately, breathing in silica dust caused by chipping, cutting, drilling, or grinding soil, granite, slate, sandstone or other natural materials can lead to chronic lung disease. As a thoracic surgeon at West ia University Hospital, Dr. Robert Herron has treated a wide variety of lung conditions.
Inhaling Concrete or Stone Dust. Some of the most hazardous dust on job sites can be released by cutting, grinding or blasting concrete and engineered stone. You may also accidentally inhale such dust by breathing in the material when opening a bag. The dangers of inhaling concrete dust and stone dust should never be played down.

Characteristics of the person inhaling particles can also influence the effects of dust. Breathing rates and smoking are among the most important. The settling of dust in the lungs increases with the length of time the breath is held and how deeply the breath is taken. Whether breathing is through the nose or mouth is also important.
People working in construction and demolition, stone masonry, pottery, sandblasting, and mining industries are the most affected. Silicosis mainly happens after years of inhaling silica and quartz dust. Additionally, …
There are few longitudinal data, but recent studies report a dose–response relationship between cement production dust exposure and declining lung function indicating a causal relationship, and underlining the need to …
The average silica content of the dust was 9%. The average cumulative dust exposure was 7.0 mg/m(3) year and cumulative silica exposure was 0.6 mg/m(3) year. Significant associations between exposure to concrete dust and a small lung function (FEV(1)/FVC ratio, MMEF) loss were found, independent of smoking habits and of a history of allergy.
The dust produced while cutting, drilling etc dried concrete and mortar can cause more serious lung disease. More information on assessing and controlling this risk can be found in the section on construction dust. Control. Prevent: Where possible think about eliminating or reducing the amount of cement used and contact with it. Consider:
One such process is breathing. We breathe while we're awake, working, and even while we sleep. We are breathing all the time! ... Dust enters our lungs in the same way that other gases do. As stated above, we understand that air is a mixture of several constituents, meaning that we breathe in huge amounts of these particles …
Not likely. While breathing concrete dust and soot is not good for you, harmful effects generally would come from prolonged exposure over a period of months of breathing high dust levels.
The most important pieces of safety equipment for concrete mixing are goggles, gloves, and masks. This guide has been specifically curated to walk you through the importance of wearing a mask when mixing concrete. It is quintessential to wear a mask while mixing cement since, without one, you'll be inhaling harmful cement dust that contains ...
experiments. Different samples of conventional concrete and stone dust concrete were prepared and tested. It was concluded that strengthen properties like compressive strength and tensile strength increased when stone dust was replaced by more than 60% 9. Bhiksham V., Kishore R. and Raju N.H.M. worked on concrete of M40 grade.
After water, concrete is the most widely used material on Earth, and millions of people work with it every year in this country. Unfortunately, inhaling concrete dust can cause serious and even fatal diseases such as silicosis, COPD (chronic obstructive pulmonary disease), and lung cancer because it usually contains silica.
The reduction in lung function was probably associated with high cement dust exposure. In parallel to our findings, Merenu et al. investigated the effect of cement dust exposure on 56 cement factory workers with a mean of 10 years exposure to cement dust on lung function. They found that the vital capacity and forced expiratory volume in …
