Guide to prevent silica exposure during asphalt operations

A new document  from the National Institute for Occupational Safety and Health document outlines best practices for minimizing the risk of crystalline silica exposure during asphalt pavement milling.

Silica dust can be generated by asphalt milling machines during road resurfacing. Exposure can lead to a number of diseases, including silicosis and lung cancer.

The document, created in partnership with the Lanham, MD-based National Asphalt Pavement Association, recommends engineering controls such as ventilation and water sprays to lower the risk of airborne dust exposure.

In related news, the Silver Spring, MD-based Center for Construction Research and Training, also known as CPWR, partnered with NIOSH and NAPA to create a field guide for controlling silica dust exposure during asphalt paving operations. The guide provides facts on silica and includes an example of a daily dust control checklist.
