Railroad Emphysema

Railroad workers' exposure to certain substances can put them at greater risk of developing lung ailments, including COPD. Many of these include coal and diesel fumes. Some workers also develop respiratory illnesses from smoke from welding and cigarettes.

The walls of the air sacs within the lungs are affected by emphysema. This can make breathing difficult. It is a form of chronic obstructive respiratory disease (COPD).

Smoking is the main cause of COPD. Other causes include an absence of a protein called alpha-1 antitrypsin as well as serious lung infections.

Coal and Mineral Dusts

Inhaling fumes and Railroad Emphysema dust from working with certain chemicals, coal, grain cotton, wood or even cotton increases the risk of developing Emphysema. Smoke from secondhand sources and pollution from the environment such as car exhaust can also increase your risk.

Recent studies have reported that fossil fuel combustion is the primary cause of ambient PM2.5-related mortality. The fugitive dust that coal transport could also be a major cause. About 70% of coal is delivered by trains in the United States. It is believed that fugitive dust from trains is responsible for around half of all coal related particulate matter.

Coal dust is a harmful mixture of metals, including arsenic and mercury as well as uranium. It can release toxic substances into water and soil. It may also stick to the leaves of nearby vegetation that reduce photosynthesis, and depriving it of nutrients. It can even cause the death of wildlife and plants.

Researchers have discovered that when coal trains pass the train, concentrations of fine particles, also known as PM2.5 are nearly 90 percent higher than when a freight train crosses. The study was conducted in Richmond, California, a highly populated and racially diverse community with high rates asthma and respiratory diseases. The study tested coal trains, both fully loaded and empty (unloaded) to be able to simulate real-world conditions for long-haul coal transportation. They also studied methods of loading coal on trains to find out how chemical binders can help in reducing the release of coal dust.

Silica Dust

Silica is among the most abundant minerals found on Earth. It is found in a variety of materials that include sand, soil as well as concrete, rock and masonry. It could be hazardous in the event that it becomes airborne and is inhaled by employees. The tiny crystalline particles could scrape and tear the lining of the nose sinuses, nasal passages and sinuses. This can cause the condition known as silicosis. This lung disease is incurable and can affect the lungs ability to absorb oxygen. This disease can also cause chronic Obstructive Lung Disease (COPD) or kidney disease. Smoking reduces the ability of the lungs to eliminate silica dust.

Workers are exposed crystallized silica through tools that release dust that is airborne. This includes cutting drills, cutting and grinding. The mineral is also expelled by trains. In an NIOSH study conducted at CSX Radnor Yard, it was found that employees in the track department were exposed to dangerous levels of silica. This was due to the silica dust used to brake locomotives, which was found in Railroad Rad yards and shops.

The most effective way to protect yourself from exposure to crystalline silica is to use personal protective equipment that is fitted correctly. Additionally, employers must provide proper training on how to use this equipment. This is particularly important for employees with facial hair, as particles can be absorbed into the hair's lungs.

Secondhand Smoke

COPD, emphysema, and other lung diseases can be caused secondhand smoke. The chemicals in smoke such as ammonia, formaldehyde and sulphur can cause irritation to the eyes as well as the throat, nose and lungs, and can cause or worsen asthma. In addition when a woman is exposed to smoke while pregnant the chemicals could affect the unborn baby and cause numerous health issues including respiratory infections.

Railroad Asthma workers who work in enclosed cabs of locomotives are often exposed to diesel exhaust and secondhand smoking. Many railroads were hesitant to enforce smoking bans for trains, despite widespread evidence of the negative effects of secondhand smoke.

Silica dust poses a risk to railway workers, especially those who manage the rail yard or shops. The fine dust, which is able to be inhaled, could cause respiratory diseases like silicosis as well as occupational asthma. It could also lead to chronic bronchitis. It can also be mixed with other substances that could cause lung damage, for example asbestos, coal and diesel fumes to produce toxic smoke that is hazardous to breathe.

Other lungs-related hazards include herbicides used to destroy unwanted vegetation, and welding fumes which contain silicates and metallic oxides. These fumes can cause lung injuries and increase the risk of developing alpha-1-antitrypsin deficiency (AATD) an illness caused by the breakdown of a protein known as beta-1 antitrypsin found in the lungs.

Exposure to Diesel Exhaust

Diesel exhaust, or diesel smoke, is a toxic chemical mix that consists of hundreds different compounds. Many of these particulates such as sulfur dioxide, nitrogen oxides and polyaromatic hydrocarbons, are regarded as carcinogens. Diesel exhaust exposure over time can lead to a variety lung diseases and illnesses including chronic obstructive lung disease (COPD).

Recent research on the health of workers on railroads' lungs discovered exposure to diesel exhaust increases the risk of developing lung cancer. This finding is consistent and based on direct exposure to diesel exhaust and indirect exposure via smoking in the presence.

The study gathered information from a vast cohort of Railroad Mds workers who held positions that exposed them to diesel exhaust from 1959 until 1996. The results show that, in addition to being associated with an elevated risk of lung cancer exposure to diesel exhaust was associated with an increased risk of dying from COPD. This effect was evident after adjustment for smoking history and it was proportional to the amount of time employed in jobs exposed to diesel. The researchers conclude that diesel exposure in the railway industry is a major cause of the high prevalence of respiratory illness among career railroaders. This is particularly true for those who smoke throughout their careers. They are at risk of suffering from debilitating and life-threatening lung conditions like emphysema, secondhand smoke-induced asthma, mesothelioma and lung cancer.
