Preventing Needlestick Injuries at COVID–19 Vaccination Sites
The need to administer large numbers of COVID–19 vaccines means work conditions may be dramatically different from the traditional setting. Administering vaccines to a large number of people in a variety of settings may increase the risk for needlestick injuries among vaccinators and other vaccination site workers. Needlestick injuries have the potential to transmit bloodborne pathogens (BBP), like hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV). This blog recommends safety measures to reduce needlestick injuries and exposures to bloodborne pathogens. Read More >

To protect healthcare workers, other patients, and visitors from exposure to airborne infectious diseases, patients in hospital settings sometimes need to be placed in airborne infection isolation rooms (AIIRs). AIIRs contain specific engineered features to isolate and more-quickly remove potentially infectious patient aerosols so that they do not infect others. Isolation rooms are expensive, costing Read More >

The hierarchy of controls shows us that engineering controls can protect workers by eliminating or reducing hazardous conditions to acceptable exposure levels. The idea behind the hierarchy is that the control methods at the top of the graphic are potentially more effective and protective than those at the bottom. Following the hierarchy of controls can Read More >

If you haven’t purchased your 20 pound Thanksgiving turkey or your 10 pound bag of potatoes rest assured employees at your local grocery stores are busy restocking the shelves each day with your favorite Thanksgiving foods. It‘s hard enough lifting those items into your cart but what about the workers who haul those tons Read More >
Posted on by 23 CommentsBuy Quiet Update
Several years ago NIOSH started the planning process for a “buy quiet” initiative to encourage companies to purchase or rent quieter machinery and tools to reduce worker noise exposure. This initiative also aimed to provide information on equipment noise levels and promote manufacturers to design quieter equipment. NIOSH is now pleased to announce the official Read More >

Background It is difficult to estimate how many workers are involved in this field. By one estimate, there are 400,000 workers worldwide in the field of nanotechnology, with an estimated 150,000 of those in the United States [Roco et al. 2010]. The National Science Foundation has estimated that approximately 6 million workers will be Read More >

On farms, manure storage facilities are used to store animal waste, which can then be used for fertilizer. Farmers or farm workers may need to enter the facilities to repair or maintain equipment, such as pumps and intake hoses. These confined spaces are often oxygen-deficient atmospheres and can contain toxic and/or explosive gases that create Read More >

Despite a decades-long effort to raise awareness about the importance of roll over protective structures (ROPS) in preventing injury and death from tractor roll overs, tractor overturns continue to be the leading cause of occupational agricultural death in the United States. While all tractors produced since 1986 come with ROPS as standard equipment, farm tractors Read More >

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 >

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 >

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 >
