Dangers of Bathtub Refinishing

At least 14 workers have died since 2000 as a result of using stripping agents containing methylene chloride during bathtub refinishing.  Many stripping products (including those that may also be available to consumers) contain high percentages of methylene chloride. Methylene chloride is extremely dangerous when not used properly.  Alternative products and processes exist for bathtub Read More >

Worker Exposure to Crystalline Silica During Hydraulic Fracturing

Hydraulic fracturing or “fracking”  is the process of injecting large volumes of water, sand, and chemicals into the ground at high pressure to break up shale formation allowing more efficient recovery of oil and gas.  This form of well stimulation has been used since the late 1940s, but has increased substantially over the last 10 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 >

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 >
