The OSHA Safety Data Sheet lists the following hazards when using lime: Lime is a dry, powdery substance that can produce significant dust. This dust can be a severe irritant to the skin and the mucus membranes of the eyes, mouth and lungs. Keep skin covered as much as possible (including face, neck and wrists).
Lime plasters are safe to use. However, the health risks must be understood. Lime is caustic, which means it can cause burns if it comes into contact with your skin or eyes. As a general guideline, always wear good eye protection and gloves when working with lime. In addition, a dust mask should be worn when removing old …

The dust (or mist) collection efficiency of filter materials also varies. Filter cartridges are available in three efficiency levels: 95%, 99%, and 99.97%, designated as 95, 99, and 100. For example, an N95 filter is 95% efficient; an N99 filter is 99% efficient; and an N100 filter is 99.97% efficient. The most commonly purchased filter types ...
Silicosis is a lung disease caused by inhaling very tiny crystalline particles of silicon dioxide, or silica. If you have it, you'll have symptoms of coughing, inflammation (swelling) and fibrosis (scarring). …
7 Occupational exposure to cement dust might cause toxic effect on vital organs such as respiratory, renal and liver. 8 Cement is a dark grey colored powdery substance of aluminis, silica, lime ...
contact with cement dust and consult a physician. • Use soap and water to wash off dust to avoid skin damage. • Wear a P-, N- or R-95 respirator to minimize inhalation of cement dust. • Eat and drink only in dust-free areas to avoid ingesting cement dust. Wet Concrete Hazard: Exposure to wet concrete can result
Exposure to silica dust can cause a range of respiratory problems, with silicosis being the most severe. Other health risks include lung cancer, chronic obstructive pulmonary disease (COPD), and kidney disease. The severity of health effects depends on factors such as the duration and intensity of exposure, as well as individual susceptibility.
Cement-based products, like concrete or mortar, can cause serious skin problems such as dermatitis and burns. Fine cement and concrete dust can land on exposed skin, and get trapped between loose clothing and skin. The dust reacts with sweat or damp clothing to form a corrosive solution, which will damage your skin.
Breathing crystalline silica dust can cause silicosis, which in severe cases can be disabling, or even fatal. When silica dust enters the lungs, it causes the formation of scar tissue, which makes it difficult for the lungs to take in oxygen. There is no cure for silicosis. Silicosis typically occurs after 15–20 years of occupational exposure ...
A 75-year-old woman—nonsmoker, and construction laborer involved in mixing concrete and tiling—had exposure to cement dust for 30 years. There was no history of exposure to biomass fuel or passive smoking. She had been using gas stove for cooking for approximately 1-2 hours daily. She presented with a history of cough with expectoration …
Construction Dust is a general term used to what may be found on a construction site. There are three main types: Silica dust – Silica is a natural mineral present in large amounts in things like sand, sandstone and granite. It is also commonly found in many construction materials such as concrete and mortar. The silica is broken into very ...
Using crushing machines at construction sites to reduce the size of large rocks, concrete, or construction rubble can generate respirable crystalline silica dust. When inhaled, the …
Silica is the biggest risk to construction workers after asbestos. Heavy and prolonged exposure to RCS can cause lung cancer and other serious respiratory diseases. HSE commissioned estimates it was responsible for the death of over 500 construction workers in 2005. In addition to the risks from lung cancer, silica is also linked to other ...
