The National Institute for Occupational protection and wellness (NIOSH) is rolling out a document through the Silica/Asphalt Milling Machine Partnership that provides recommendations to help reduce respirable silica exposures during asphalt pavement milling in highway building. Shows from the document is going to be provided on March seventeenth in Baltimore, Maryland by Dr. Christine Branche, Director of NIOSH’s workplace of Construction security and wellness, at World of Asphalt Show & meeting 2015, the leading exposition and knowledge resource for the asphalt business.

Approximately 367, 000 U.S. employees are utilized in highway, street, and bridge construction and generally are prone to exposure to respirable crystalline silica.[i] Workers make use of a number of equipment when getting rid of and recycling asphalt pavement; a lot of them make use of cold-milling machines with toothed, rotating cutters that routine and remove the pavement, or work with close distance in their mind. Dust produced from the cold-milling machines often contains respirable crystalline silica which may be transported by currents to the atmosphere workers breathe. The NIOSH document of best practices, which presents a lot more than a decade of collaborative research between lovers working beneath the Silica/Asphalt Milling Machine Partnership, provides recommendations such as air flow settings as well as water sprays used to cool off the cutting teeth of milling devices, decreasing silica dirt visibility.

“Inhalation of respirable crystalline silica can cause silicosis, a debilitating and possibly fatal lung disease, along with other possible adverse wellness outcomes, “ stated NIOSH Director John Howard, M.D. “This collaborative work by labor, business and government reflects the current understanding of guidelines and a cooperation who has succeeded in establishing suggested manufacturing settings for those worksites.”

Within their studies, NIOSH and partners obtained 42 worker personal respiration zone air examples at 11 various highway construction web sites. They unearthed that machines that follow this well-designed dust control approach reduced employee exposures to respirable crystalline silica from asphalt milling operations.

NIOSH plus the Silica/Asphalt Milling Machine Partnership through the following as recommendations to reduce employee contact with respirable crystalline silica:

  • Keeping ventilation settings on all new asphalt milling machines
  • Maximizing cover across the cutter drum and conveyor belts of milling devices
  • Designing a socket that releases dust at high-speed away from the employee, if ventilation control from the device does not already feature a dirt collector
  • Liquid sprays which are familiar with avoid or suppress dust on milling machines if ventilation dust settings are not offered

The document also provides device manufacturers guidance for evaluating existing and future dust controls. To gain access to top practices document, kindly see: . For more information on manufacturing controls for silica in building please visit:

NIOSH could be the national agency that conducts study and tends to make suggestions for avoiding work-related accidents, diseases, and fatalities. To find out more about NIOSH visit .
