Nanotechnology: Human and Environmental Exposure Assessment of Nanomaterials Workshop

Because of the relative newness of nanotechnology, very little exposure data have been reported in the scientific literature. At this stage, measuring or determining risk becomes a little like trying to solve a mystery when major clues are missing. Scientists and engineers face this challenge even as the market for nanotechnology grows, and along with it, an increasing demand from diverse parties for guidance to underpin its responsible development. Read More >

Persistent Pulmonary Fibrosis, Migration to the Pleura, and Other Preliminary New Findings after Subchronic Exposure to Multi-Walled Carbon Nanotubes

Multi-walled carbon nanotubes (MWCNTs) are a type of engineered nanomaterial that shows promise for creating stronger, more durable building materials; improving cancer therapies; creating more efficient means of energy generation, storage, and transmission; and speeding computer processes. However, as with other types of engineered nanomaterials, the potential occupational health implications of MWNCTs are not well understood at this emergent stage of the technology. Read More >

Nail Salon Table Evaluation

NIOSH is requesting that developers, manufacturers, and vendors of vented nail tables (VNTs) submit new, unused, downdraft VNTs for a free evaluation. The NIOSH research will include an evaluation of VNT airflow and capture characteristics, noise level, ergonomic features, and filter life. Results of the research and recommendations from NIOSH will be communicated back to the submitter with the hope of providing valuable information for maximizing the efficiency of VNTs. Read More >

Violence Against Pharmacists

Violence against pharmacists differs from violence experienced by other healthcare workers. Increasingly, pharmacists face violence from robberies at their workplace. Across the United States, reports of pharmacy robberies specifically related to the theft of Oxycontin and Vicodin have been reported.  Read More >

NO2 Emission Increases Associated with the Use of Certain Diesel Particulate Filters in Underground Mines

Emissions of and exposure to diesel particulate matter can sometimes be controlled through use of newer diesel engines, better engine maintenance, alternative fuels, or ventilation upgrades. Some mines may need to use diesel particulate filters, however. This has created concern about potential exposure to nitrogen dioxide (NO2) resulting from their use.  Read More >

Improved Criteria for Emergency Medical Protective Clothing

Over one million firefighters and an additional 500,000 emergency medical technicians and other first responders are engaged in emergency medical service (EMS) operations. NIOSH research has led to revised standards for personal protective equipment for EMS workers and, in turn, the development of new equipment and products providing a level of protection not previously available to the nation's EMS responders.  Read More >

Preventing Death and Injury in Tractor Overturns with Roll-Over Protective Structures

Tractor overturns are the leading cause of occupational agricultural deaths in the United States. Between 1992 and 2005, 1,412 workers on farms died from tractor overturns. The Roll-Over Protective Structure (ROPS) was developed to protect tractor operators from death and disability from these events by providing a protective zone for the operator in during a tractor overturn. Read More >

1-BP: A Potential Occupational Hazard

The toxic nature of 1-BP is not fully understood. Case reports demonstrating neurotoxic, reproductive, development and other health effects in workers who use or make 1-BP indicate that the brominated solvent may represent an unrecognized occupational health risk. In this week's issue of the Centers for Disease Control and Prevention's Morbidity and Mortality Weekly Report, the National Institute for Occupational Safety and Health (NIOSH) presents two independent cases of 1-BP exposed workers diagnosed with the clinical manifestations of neurotoxicity. Read More >

Fire Fighter Fatality Investigation and Prevention Program

In 1998 the NIOSH Fire Fighter Fatality Investigation and Prevention Program was created to conduct independent investigations of fire fighter line of duty deaths and to formulate recommendations for preventing future deaths and injuries. As NIOSH enters the 10th year of the Fire Fighter Program we are working to better reach small and rural fire departments with the results of our fatality investigation reports and prevention recommendations. We request your assistance in helping us achieve this goal. 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 >

Immigrant Worker Safety and Health

Immigrant workers face a disproportionate risk for workplace injury and illness. At the Safety, Health and Social Justice for Immigrant Workers - Lessons from the NIOSH Environmental Justice Projects session of the 2008 American Public Health Association's annual conference "Public Health Without Borders" (October 25-29), a panel will present the experiences from six of the environmental justice projects addressing safety and health concerns of immigrants working in farming, poultry processing, and restaurant and domestic work. For those unable to attend the session, we would appreciate feedback through this blog. Specifically, what experience have others had with developing successful interventions for immigrant workers? Additionally, what types of materials are needed to better assist safety and health professional to provide information and training to foreign-born workers? Read More >

Research to Practice for Injury Prevention

NIOSH is hosting the fourth National Occupational Injury Research Symposium (NOIRS) on October 21-23, 2008, at the Sheraton Station Square in Pittsburgh, Pennsylvania. NOIRS is the only national forum for presenting research methods, data, and findings focused exclusively on the prevention of occupational injuries. The goal of the NOIRS is to provide a forum for researchers and other professionals to share their findings and experiences aimed at preventing traumatic occupational injuries through research and prevention. Read More >

Preventing Health Hazards from Metal Working Fluids

Metal working fluids are used to lubricate, cool, prevent corrosion of, and remove chips from tools and metal parts during grinding, cutting, or boring operations. There are several types of MWFs: straight or soluble oils, semisynthetic oils, and synthetic oils. Exposures to MWFs can occur through inhaling aerosols, skin contact with contaminated surfaces, and splashing of fluids. Employees who have been exposed to MWFs often report skin disorders (skin irritations, oil acne, and rashes); eye, nose, and throat irritation; and respiratory symptoms (cough, asthma, or other breathing problems). Read More >

Preventing Back Injuries in Health Care Settings

Healthcare workers often experience musculoskeletal disorders (MSDs) at a rate exceeding that of workers in construction, mining, and manufacturing. These injuries are due in large part to repeated manual patient handling activities, often involving heavy manual lifting associated with transferring, and repositioning patients and working in extremely awkward postures. 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 >
