subject: Silicosis Prevention [print this page] Silica exposure occurs when a person is exposed to crystalline silica, which is a basic component of soil, sand, granite, quartz and other minerals, and is considered in the United States to be a human lung carcinogen, which when breathed in can lead to disability or even death. People who work in industries such as abrasive blasting, foundry work, rock drilling and tunneling work, just to name a few, are at serious risk of exposure, which can lead to silicosis. Exposure can also result in lung cancer, pulmonary tuberculosis and other adverse health effects.
The symptoms of silicosis depend on its severity. Doctors have divided the condition into three classifications based primarily on the acuteness of the disease. The first is called chronic silicosis, which is considered to be the most common. This from usually occurs after at least 15 years of constant exposure. Symptoms include shortness of breath, fatigue, chest pain or respiratory failure. However, sometimes no symptoms will be present. Therefore, those working in high risk occupations should get regular chest x-rays to determine if they have been exposed.
The more dangerous type of this disease is called accelerated silicosis, which can happen after five to ten years of exposure. Symptoms can include, weakness, shortness of breath and weight loss.
The most dangerous form is known as acute silicosis, which can occur in two years or in as little time as a couple of months. Acute silicosis results from being exposed to extremely high dosages of crystalline silica. Symptoms can include debilitating shortness of breath, weakness, chronic cough, weight loss and even death.
There are certain preventative steps that workers and companies can do to ensure that their employees stay protected against exposure. First, if possible materials with crystalline silica can be replaced with safer materials. Second, in areas where there is a high risk of exposure, protective equipment and exhaust ventilation systems can be used. Third, water sprays can be used to control exposure. Fourth, workers should only wear certified respirators. Fifth, companies should offer training programs, take monitoring steps, and perform health screenings to determine if exposure has occurred. Finally, people who work in risk areas should wash their hands and clothes before and after work. A more comprehensive list of guidelines can be found at the Center for Disease Control.
Additionally, works working in the Unites States can review the government's federal guidelines which show the maximum level of crystalline silica a person can be exposed to in period of eight hours. These guidelines also state other requirements that can help protect against the disease.
