In a study which has implications for occupational health, European researchers have found that certain non-toxic substances can have a negative impact on neuronal development when mixed with other substances.
The in vitro research project conducted by the European Commission’s Joint Research Centre (JRC) examined this “cocktail effect” by using chemical products belonging to different classes.
For workers in a variety of industries, exposure to chemicals is commonplace. American workers handle, transport, or encounter thousands of chemicals every day, from cleaning products to industrial solvents. Although many of these chemicals have important uses, they can also be harmful to workers who are exposed to them.
The American Society of Safety Professionals (ASSP) Foundation is accepting online applications for scholarships and professional development grants through Dec. 1 for the 2019-20 academic year. More than $400,000 is available to occupational safety and health students and professionals, thanks to the generosity of corporate donors and the ASSP community.
The Spanish government’s recent proposal to double the occupational exposure limit value (OELV) for silica is being met with opposition by worker safety advocates. The current limit is 0.05 mg/m³. Under a draft decree presented to the national occupational health and safety commission earlier this month, OELV would be raised to (0.1mg/m³).
Engineered nanomaterials (ENMs) are materials that are intentionally produced to have at least one primary dimension less than 100 nanometers. These materials have new or unique properties different from those of larger forms of the same material, making them desirable for specific product applications.
ACGIH® is pleased to announce new members for its 2020 Board of Directors and its 2020 Nominating Committee.
ACGIH®’s membership elected three (3) members to serve as Directors on the Board of Directors.
ACGIH® will present the Notations: How Are They Assigned and How Should They Be Used in Industrial Hygiene Practice? webinar on November 19, 2019. This webinar will focus on the Notations recommended by the Threshold Limit Values for Chemical Substances (TLV®-CS) Committee.
OSHA last week issued a final rule approving two additional quantitative fit testing protocols for inclusion in appendix A of the Respiratory Protection Standard. These protocols are: 1. The modified ambient aerosol condensation nuclei counter (CNC) quantitative fit testing protocol for full-facepiece and half-mask elastomeric respirators; and 2. The modified ambient aerosol CNC quantitative fit testing protocol for filtering facepiece respirators.
The weight of scientific evidence has not linked cell phones with any health problems. Cell phones emit low levels of radiofrequency energy (RF). Over the past 15 years, scientists have conducted hundreds of studies looking at the biological effects of the radiofrequency energy emitted by cell phones.
TLVs® and BEIs® are often recognized as “safe levels” for worker exposures to chemical substances and physical agents. Proper application of TLVs® and BEIs® are essential to today’s practice of industrial hygiene.
