Wildland Fire Fighting Safety and Health

Wildland fires continue to increase in the Western United States as hot, dry and windy conditions persist, resulting in an extended fire season and factors conducive to fires. Currently, drought conditions are prevalent in the West due to low snow-pack levels, below average rainfall, record setting temperatures and high winds, resulting in a greater than Read More >

Worker Exposure to Crystalline Silica During Hydraulic Fracturing

Hydraulic fracturing or “fracking”  is the process of injecting large volumes of water, sand, and chemicals into the ground at high pressure to break up shale formation allowing more efficient recovery of oil and gas.  This form of well stimulation has been used since the late 1940s, but has increased substantially over the last 10 Read More >

Erionite: An Emerging North American Hazard

Recent cases of lung disease suggest that erionite, a naturally-occurring fibrous mineral with health effects similar to asbestos, may pose a greater threat to workers than previously realized. Read more about erionite and how to prevent exposure in at-risk occupations such as road construction and maintenance work in areas where erionite-containing gravel or soil is present. Read More >

The Continuing Persistence of Silicosis

Silica is the most abundant compound in the earth's crust. Inhalation of crystalline silica is the only cause of silicosis, a preventable but incurable type of lung fibrosis. Inhalation has also been associated with lung cancer, tuberculosis, COPD and other conditions.  Read More >

Low-dose CT Scans and Lung Cancer Screening in the Occupational Setting

Lung cancer mortality is high and better survival prognosis for early stage cases makes early detection an appealing public health strategy. For years studies have been conducted to find an effective screening method; the NLST is the first randomized trial to show a significant reduction in mortality from lung cancer with low-dose CT screening.  Read More >
