The Effectiveness of DIY Air Filtration Units
Portable air filtration units, or air cleaners, remove airborne particles (called aerosols) from the air indoors. Air filtration units were widely used during large wildfire outbreaks in the western United States,[1] and their use surged nationwide during the COVID-19 pandemic as a way to reduce exposure to aerosols containing the SARS-CoV-2 virus.

In 1996, after conducing multiple health hazard evaluations, NIOSH released a bulletin recommending the control of surgical smoke created during laser or electric surgical procedures. Since the 1990s the Association of Perioperative Registered Nurses (AORN) has recommended the evacuation of all surgical smoke. Yet, surgical smoke is still inhaled daily by nurses in the operating Read More >

Engineered stone countertops, also known as “quartz surfacing,” are made from quartz aggregate held together with a resin binder. These materials are similar in appearance to natural stone and have become increasingly popular for use in home building and home improvement. Quartz surface imports to the United States have increased approximately 800% during 2010–2018 (U.S. Read More >

Sensors are an increasing presence in our lives—from wearable gadgets to smart buildings, from autonomous vehicles to smart cities. In occupational health and safety, sensors are used widely for exposure monitoring, emergency response, and safer worker-machine interfaces. The use of sensors as real-time respirable dust monitors is a targeted application with its own specific challenges. Read More >

There is no safe level of exposure to secondhand smoke, and avoiding this preventable health hazard is particularly important for the health of pregnant women and their unborn babies. Secondhand smoke exposure is associated with chronic diseases such as lung cancer, coronary heart disease, and stroke and with adverse reproductive effects, including low birth Read More >

A new engineered stone countertop product known as “quartz surfacing,” was created in the late 1980s by combining quartz aggregate with resins to create a product for use in home building and home improvement. Manufacturing of this material, including products such as CaesarStone™, Silestone™, Zodiaq™, or Cambria™ is a fast growing industry. First made in Read More >

As we enter another influenza season, one question continues to vex medical and public health professionals: How do you stop people from catching the flu? The best way to prevent the flu is by getting an influenza vaccine every year. However, in the event of a large-scale influenza outbreak of a new virus strain or Read More >

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 >

Simply working in a casino does not mean dealers must gamble with their health. Results of new research conducted by NIOSH on secondhand smoke—the exposure of non-smokers to tobacco smoke—confirm that dealers at the casinos investigated were exposed to secondhand smoke. 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).
