A recently released NIOSH guidance document on handling titanium dioxide (TiO2) powders in the workplace is possibly the first to recommend separate occupational exposure limits for the same material based on particle size. This document reflects increasing attention to evaluating and mitigating risks of emerging hazards in the workplace before adverse health effects occur in workers. Read More >

Yesterday, the Surgeon General issued the 30th Surgeon General's Report on the dangers of smoking tobacco. Tobacco use remains the leading cause of preventable death in the United States, and is responsible for 443,000 deaths each year. Tobacco use can increase risk of illness for those exposed to carcinogens in the workplace and second-hand smoke can place non-smoking workers at risk for smoking-related diseases. Read More >

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 >

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.

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 >

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).
