Silica Dust: A Human Carcinogen
Silicosis, the most prevalent occupational lung disease globally claims the lives of thousands around the world, according to the World Health Organization (WHO). Occupations that carry health risk include ceramic and glass manufacturing, construction work and quarrying. Workers in these occupations are exposed to high levels of silica dust from activities such as sandblasting and drilling, which creates large amounts of fine dust. Safety gear such as a high-filtration dust mask, protective goggles and gloves minimise the risk of silicosis and other occupational illnesses and injuries.
Potter’s Rot Damages Lung Tissue
Silicosis, also known as Potter’s rot, usually develops years after exposure to silica dust. It is characterised by shortness of breath and causes scarring of lung tissue. Individuals afflicted with silicosis are at elevated risk of developing lung cancer and the combination of silicosis and tuberculosis worsens prognosis. Unlike some conditions that improve when the cause is removed from the environment, silicosis progressively worsens even when there is no further exposure to silica dust.
In developing countries where safety gear is either not mandatory or strictly enforced, dust generation is not controlled effectively and the condition still affects many workers in occupations that expose them to silica dust.
How Does a Dust Mask Work to Keep You Safe?
A quality dust mask should meet several criteria, such as comfort and most importantly, the safety factor. Between passive paper masks and technologically advanced alternatives that incorporate an innovative breath-responsive technology, the latter is favourable for its comfor and greater efficiency. Comfort is an important consideration when it comes to compliance with safety regulations.
The motor in the dust mask is designed to draw out exhaled carbon dioxide for user comfort by creating positive pressure in the mask. This means the safety mask does not have to be fit tightly on your face, making it user-friendly and comfortable.
