Silica Dust: What Are The Hazards
According to the World Health Organization (WHO), silicosis is the most common occupational lung disease worldwide and claims the lives of thousands annually. Occupations that carry health risk include ceramic and glass manufacturing, construction work and quarrying. Workers in these occupations risk high levels of exposure to silica dust from activities such as sandblasting and drilling, which creates large clouds of 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 fibrosis of lung tissue. Silicosis suffers are at increased risk of developing lung cancer and the comorbidity of silicosis and tuberculosis significantly increases the mortality rate. 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 nations where protective gear is either not stringently enforced or compulsory, 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 motor-powered options that incorporate an innovative breath-responsive technology, the latter is favourable for its comfort and greater efficacy. Comfort is a priority when it comes to compliance with safety regulations.
Designed to draw out exhaled carbon dioxide for greater comfort, the motor creates positive pressure in the mask. This means the safety mask is fitted for comfort, feels natural and makes it comfortable to wear.
