N95 Respirators and Surgical Masks

The emergence of H1N1 has created considerable interest about the use of surgical masks and respirators as infection control measures. Given the recent issuance of revised CDC infection control guidance for healthcare personnel that include recommendations for use of N95 respirators, NIOSH has posted a new blog that examines the scientific principles behind the design and performance of these devices. Read More >

Respiratory Protection for Terrorist Threats and Other Emergencies

This September 11th marks eight years since the devastating attacks on the World Trade Center. Since then, NIOSH has developed a systematic approach to identify the hazards that responders would face, assess the capabilities of existing respiratory protection equipment to provide protection against viable threats using benchmark testing, and set certification standards that stretch the capabilities of the protective technologies to enhance the protection offered to responders during CBRN events. Read More >

Secondhand Smoke and Casino Dealers

Simply working in a casino does not mean dealers must gamble with their health. Results of new research conducted by NIOSH on secondhand smoke—the exposure of non-smokers to tobacco smoke—confirm that dealers at the casinos investigated were exposed to secondhand smoke. Read More >

Using Digital Chest Images to Monitor the Health of Coal Miners and Other Workers

Conventional screen-film chest radiographic imaging has been an indispensable tool for monitoring the lung health of miners and other dust-exposed workers. Over the next decade, conventional film-based radiography will be completely replaced by digital radiography systems in the United States and elsewhere.  Read More >

Diacetyl and Food Flavorings

Commercial flavorings used in the food service industry are often complex mixtures of flavoring chemicals, many of which are volatile, meaning that they evaporate into the air from their liquid or solid form. Diacetyl is a prominent chemical ingredient in butter flavorings and is a component of the vapors coming from these and other flavorings. Inhalation of butter flavoring chemical mixtures, including diacetyl, has been associated with severe obstructive lung disease popularly know as "popcorn lung." Read More >

Faces of Black Lung

Black lung disease, which is caused by inhaling coal mine dust, results in scarring of the lungs and emphysema, shortness of breath, disability, and premature death. While the prevalence of black lung disease had decreased by about 90% from 1969 to 1995 following the enactment of the Coal Mine Health and Safety Act, the downward trend of this disease in coal miners has stopped. Since 1995, the prevalence of black lung cases has more than doubled. Read More >

The “No Fit Test” Respirator Research Workshop

NIOSH is hosting the "No Fit Test" Respirator Research Workshop on November 6, 2008. The workshop aims to examine how the latest material technology (shape-changing polymers, adhesives, etc.) may be leveraged to improve current and future respirator designs including the long-term possibility of moving away from current fit-testing requirements, while preserving user protection. Read More >
