NIOSH’s Engineering Controls Database
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 >

Last week, a 19-year-old North Carolina teen was killed after being pulled feet first into a wood chipper (see news report). It was his first day on the job.Self-feeding mobile wood chippers commonly used during tree trimming operations consist of a feed mechanism, knives mounted on a rotating chipper disc or drum, and a 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 22 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 >
