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 >

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 >

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 >
