Mine workers and breathing problems

First published by Safety+Health an NSC publication

East Lansing, MI — A recent study of workers at sand, gravel and stone mines in Michigan found a higher number of doctor visits for shortness of breath compared with workers in other production industries.

Researchers at Michigan State University examined lung disease as well as exposure to silica, various allergens and other irritants among more than 1,200 surface mine workers from around the state. They asked the workers, who each had at least 15 years of experience, to complete a questionnaire and provided them with free chest X-rays and breathing tests.

Results showed “an increased prevalence of seeing a doctor for shortness of breath, possible work-related asthma and chronic obstructive pulmonary disease,” according to an MSU press release. In the release, lead study author Hailey TenHarmsel, a research assistant in the MSU College of Human Medicine, said the nature of surface mining leaves workers vulnerable to various exposure risks.

Doug Needham is executive director of the Michigan Aggregates Association, which represents 85% of aggregate mining operators in Michigan. “We are making sure the health and safety of the work itself and companies doing air monitoring aren’t exposed to anything,” Needham said. “We put in air monitors on their chest throughout a normal eight-hour day, and at the end of the day, they turn them in and get tested to ensure they weren’t exposed to any limits that will cause them harm.”

The study was published online in the Journal of Occupational and Environmental Medicine.

Bill would restore increased tax rate on coal to fund black lung disability benefits

First published by Safety+Health an NSC publication

Washington — Proposed legislation would create funding for health care and other benefits for coal miners who have black lung disease by extending, for 10 years, a recently expired excise tax rate increase on coal production.

Black lung is another name for coal workers’ pneumoconiosis – a deadly condition caused by exposure to respirable coal mine dust.

The original increase excise tax rate, which supports the Black Lung Disability Trust Fund, expired Dec. 31. H.R. 6462, introduced Jan. 20 by Reps. Bobby Scott (D-VA) and Alma Adams (D-NC), would restore it. Although mine operators are generally responsible for paying black lung benefits, the fund helps finance benefits for miners and eligible survivors or dependents when no responsible mine operator is identifiable or the operator is out of business.

Effective Jan. 1, the tax rate fell to 50 cents a ton on underground coal and 25 cents a ton on surface coal – a 55% reduction from the previous rates of $1.10 and 55 cents, respectively. The fund already stands about $5 billion in debt, according to a press release from the House Education and Labor Committee, of which Scott is chair.

The release also cites a May 2018 report from the Government Accountability Office that concluded failure to extend the previous tax rate will swell the fund’s debt to roughly $15 billion by 2050.

“Long-term funding for the Black Lung Disability Trust Fund is a necessity,” Cecil Roberts, president of United Mine Workers of America International, said in the release. “Miners are suffering from [black lung] because they dedicated their lives to providing this nation with electricity and steel. The least Congress could do is ensure that the benefits they depend on to survive will always be there.”

In a November 2020 report, the Department of Labor Office of Inspector General notes that more than three times as many coal miners were identified as having black lung disease from 2010 to 2014 compared with 1995 to 1999.

“With the number of black lung cases rapidly increasing, Congress must take action to secure health care and benefits for disabled miners,” Adams said in the release. “We can’t allow the Black Lung Disability Trust Fund to sink deeper into debt.”

In September, Sen. Joe Manchin (D-WV) introduced similar legislation (S. 2810). The bill hasn’t advanced past the Senate.

Mental illness an ‘unrecognized crisis’ among miners with black lung, study shows

First published by Safety+Health an NSC publication

Charlottesville, VA — Coal miners with black lung disease commonly face various mental health issues, including thoughts of suicide, results of a recent study conducted by researchers from the University of Virginia show.

The researchers examined data from more than 2,800 coal miners who were evaluated for anxiety, depression and post-traumatic stress disorder through a voluntary survey at Stone Mountain Health Services, a black lung clinic in Jonesville, VA. The average age of the participants – an overwhelming majority of whom were white males – was 66.

More than 1 out of 3 participants reported symptoms consistent with a major depressive disorder (37.4%) or had clinically significant anxiety (38.9%). Additionally, 26.2% exhibited symptoms of PTSD and 11.4% had considered suicide in the past year. The percentage of suicidal thoughts among all men in Virginia is 2.9.

The researchers note that the percentage “of mental illness far exceeded those documented in coal mining populations internationally.” Miners who need supplemental oxygen to assist with breathing showed accelerated rates of suicidal thoughts (15.9%), anxiety (47.7%) and depression (48.5%).

“This study highlights the unrecognized crisis of mental illness in miners that warrants urgent attention, resources and expanded care,” Drew Harris, lead study author and pulmonary medicine expert at UVA Health, said in a press release, adding that the percentage of “mental illness identified in this large population of U.S. coal miners is shocking. Improved screening and treatment of mental illness in this population is an urgent, unmet need that warrants urgent action.”

Also known as coal workers’ pneumoconiosis, black lung is a deadly but preventable condition. Rates of black lung disease have more than doubled over the past 15 years, says NIOSH, which adds that symptoms may include coughing, excessive phlegm, shortness of breath, labored breathing and chest tightness.

The agency provides free, confidential health screenings through its Coal Workers’ Health Surveillance Program.

The study was published online May 25 in JAMA Network Open.

Construction workers at higher risk of COPD, study shows

First published by Safety+Health an NSC publication

Silver Spring, MD — Workers in construction trades are at “significantly” higher risk for chronic obstructive pulmonary disease than non-construction workers, according to the results of a recent study.

A team of researchers from CPWR – The Center for Construction Research and Training, Duke University and the University of Maryland studied nearly 18,000 participants in the Building Trades Medical Screening Program, or BTMed, to determine the risk of COPD among different trades. The study involved a larger cohort than a 2010 study of construction workers at U.S. Department of Energy nuclear facilities who participated in the BTMed. Those workers were found to have increased COPD risk, according to CPWR.

Overall, 13.4% of the participants had COPD and more than two-thirds of the cases were classified as moderate to severe. Compared with non-construction workers, the participants had a 1.34 times greater risk of COPD and a 1.61 times higher risk of severe COPD.

The trades with the highest level of risk were cement masons/bricklayers (2.36 times) and roofers (2.22).

Based on the new findings, the researchers say additional preventive measures are needed to reduce workplace exposures to vapors, gases, dusts and fumes to reduce the risk of COPD. In addition, workers who smoke can benefit from cessation support and advice.

The study was published in the American Journal of Industrial Medicine.
