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 >

Buy 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 >

Controlling Exposures to Workers Who Make or Use Nanomaterials

  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 >

Preventing Deaths in Manure Storage Facilities Through Proper Ventilation

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 >

Cost-effective Rollover Protective Structure (CROPS)

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 >
