Group marks successful 10-year effort to ensure worker safety; New best practices guidance from NIOSH and field guide from NAPA/CPWR released
With a variety of new equipment and innovations as a backdrop, members of the Silica/Asphalt Milling Machine Partnership were recognized during World of Asphalt 2015. The ceremony last week marked the successful completion of the partnership’s efforts to develop and validate engineering controls for silica dust in asphalt milling operations.
The Silica/Asphalt Milling Machine Partnership — which is made up of the National Asphalt Pavement Association (NAPA), milling-machine manufacturers, labor, academia, and the National Institute for Occupational Safety and Health (NIOSH) — has worked over the past decade to design, test, and implement engineering controls for milling machines that effectively reduce potential silica exposure below OSHA’s new proposed permissible exposure limit (PEL).
During the ceremony, Dr. Christine Branche, Director of the Office of Construction Safety and Health at NIOSH, spoke on the devastating effects of crystalline silica exposure and highlighted the recent release of an asphalt milling best practices document to ensure milling machine worker safety. “Some 1.7 million U.S. workers are exposed to respirable crystalline silica in a variety of occupations, including road and highway workers,” Branche said. “It is incurable, but completely preventable.” Also released was a field guide developed by NAPA and CPWR — The Center for Construction Research and Training covering best practices for milling operations.
“Thanks to this constructive partnership between industry, equipment manufacturers, labor, and regulators, engineering controls that ensure worker protection during roadway milling operations will soon be standard equipment on milling machines,” said NAPA President Mike Acott. “It shows the sort of progress that can be made when government, labor, and industry work together, in a voluntary fashion, to address real-world issues.”

The World of Asphalt ceremony also included comments from NAPA Chairman Michael Cote, Executive Vice President & Chief Development Officer at Lane Construction Corp.; Donald “Chip” Booth, Safety and Health Director at the International Union of Operating Engineers; Scott Schneider, Occupational Safety and Health Division Director at the Laborers’ Health & Safety Fund of North America; and James H. Bevill, Chief Engineer of Cold Planers at Roadtec Inc.
About The National Asphalt Pavement Association
The National Asphalt Pavement Association (NAPA) is the only trade association that exclusively represents the interests of the asphalt producer/contractor on the national level with Congress, government agencies, and other national trade and business organizations. NAPA supports an active research program designed to improve the quality of asphalt pavements and paving techniques used in the construction of roads, streets, highways, parking lots, airports, and environmental and recreational facilities. The association provides technical, educational, and marketing materials and information to its members; supplies product information to users and specifiers of paving materials; and conducts training courses. The association, which counts nearly 1,100 companies as members, was founded in 1955.
A proposed Occupational Safety & Health Administration (OSHA) regulation concerning exposure to crystalline silica is based on decades old data and flawed economics, the American Road & Transportation Builders Association (ARTBA) says.
At issue is OSHA’s plan to regulate the worker exposure to respirable crystalline silica. Crystalline silica is found in nearly all transportation construction materials and products and can even be found naturally in the ambient air.
In comments submitted to OSHA February 11, the association contends the agency is attempting to set crystalline silica exposure limits at levels which are unworkably low. Specifically, ARTBA pointed to studies OSHA relied upon in formulating the new rule which date back to the 1930s, and do not take into account both technological and modern safety advancements that have dramatically reduced the negative health effects from crystalline silica exposure.
ARTBA noted OSHA might be doing more harm than good with its proposal, citing portions of the rule that could require workers to wear respiratory devices. “When coupling the necessity of strenuously working in high heat, amongst heat generating materials while wearing a respirator, OSHA is creating a significant, real danger to human health that far exceeds the potential hazard from silica exposure,” ARTBA said.
The association’s comments also took aim at the basis of OSHA’s economic analysis, noting the agency’s source information is difficult to verify and “the true per company cost of meeting the proposed standards” was unknown. “By averaging the cost of compliance across all workers, this could potentially understate the costs of compliance for businesses that could not meet the new standard,” according to ARTBA.
The full text of the comments can be found in the “regulatory affairs” section of www.artba.org.
Established in 1902, ARTBA is the transportation construction’s primary advocate on environmental and regulatory matters in the Nation’s Capital. ARTBA files an average of 25 sets of regulatory comments per year representing the views of the transportation construction industry on a variety of issues.

Combustible dust, it is not the most glamorous of topics but it is an important one. Why is it important? It is important because between 1980 and 2005, combustible dust incidents claimed the lives of 119 workers and injured another 718.
There is a common misconception that combustible dust hazards primarily affect the grain handling industry. That is simply untrue. Combustible dust hazards exist in many industries and manufacturing processes including: food (e.g., candy, starch, flour, feed), plastics, wood, rubber, furniture, textiles, pesticides, pharmaceuticals, dyes, coal, metal (e.g., aluminum, chromium, iron, magnesium, and zinc), and fossil fuel power generation. The handling and processing of these materials can generate very small particles. These small particles are so light that they easily become airborne. Once airborne, the particles settle on surfaces, inside crevices, and even inside the ventilation system. It takes a little more than 1/32 of an inch of accumulation over five percent of a room’s surface area to create a combustible dust explosion hazard. If disturbed, the accumulation can create a potentially explosive dust cloud.
The elements of a combustible dust explosion are fairly straight forward. You start with the traditional fire triangle of fuel, heat, and oxygen. The combustible dust acts as the fuel source. Heat generated from equipment can provide the ignition source. And the oxygen comes from the air around us. Now if you take the fire triangle and you add to it a dust cloud in a confined space, you have a recipe for a potentially catastrophic combustible dust explosion. More information concerning facility dust hazard assessment, dust control, ignition control, damage control, and training can be found on the OSHA website in its Safety and Health Information Bulletin on Combustible Dust in Industry: Preventing and Mitigating the Effects of Fire and Explosions.
Currently, OSHA does not have a comprehensive standard that addresses combustible dust hazard. However, that is about to change. OSHA has initiated rulemaking to create a comprehensive standard to control the risk of combustible dust explosions industry wide. Beginning this month, OSHA will begin its small business review of a combustible dust standard. The purpose of the small business review is to estimate the proposed rule’s economic impact on small businesses.
The small business review panel will evaluate comments from small business representatives, review the proposed rule, and review the analysis prepared by OSHA. Thereafter, the proposed rule will be published along with the panel’s report in the Federal Register. Once the proposed rule is published in the Federal Register, it will be open for comments from the general public. Any comments submitted must be considered by OSHA. In this regard, if you believe that your small business may be adversely impacted by the proposed regulation, it is important that you file a comment with the Small Business Administration Ombudsman. For more information on commenting on enforcement action, please visit the OSHA website on the Small Business Regulatory Enforcement Fairness Act (SBREFA).
Although beyond the scope of this article, it is important to note that despite the lack of a specific OSHA combustible dust hazard, OSHA may nevertheless cite employers for combustible dust hazards under the General Duty Clause, Section 5(a)(1) of the Occupational Safety and Health Act of 1970. In fact, OSHA has issued citations for combustible dust hazards in over 200 inspections since 1980. Unfortunately, enforcement under the General Duty Clause is reactive in that the citations are issued in response to an accident. Conversely, the impending proposed combustible dust standard will be aimed at prevention. A similar preventative standard established for the grain handling industry has significantly reduced the occurrence of explosions within the grain industry and has significantly mitigated their effects.
This article relied heavily on the U.S. Chemical Safety and Hazard Investigation Board (“CSB”) Investigation Report, Report No. 2006-H-1, Combustible Dust Hazard Study. The Combustible Dust Hazard Study contains a wealth of information on dust explosions basics, the CSB investigations of dust explosions, combustible dust incident data, and hazard communication and prevention. The Combustible Dust Hazard Study also contains information on the National Fire Protection Association’s two principal voluntary consensus standards to prevent and control dust explosion risks, which are NFPA 654 (Standard for the Prevention of Fire and Dust Explosions from the Manufacturing, Processing, and Handling of Combustible Particulate Solids–2006) and NFPA 484 (Standard for Combustible Metals–2006).
