Technical Tip There is a debate on whether the action level of 25 μg/m3 is able to be accurately and consistently measured. Also, many feel that some of the other provisions seem overly burdensome for the desired results. As a result, several groups involved in the construction industry, including the Construction Industry Safety Coalition, are mounting efforts to get the rule reviewed and revised to provide a more practical, yet still fully effective standard. ASA is monitoring these efforts to modify the new rule. Unfortunately, no one can predict whether the OSHA rule will be modified before the June 23, 2017, date for compliance. Thus, one should certainly review all the provisions of the new rule, and determine what your company needs to do to meet the requirements. Charles S. Hanskat is the current ASA Executive Director. He received his BS and MS in civil engineering from the University of Florida, Gainesville, FL. Hanskat is a licensed professional engineer in several states. He has been involved in the design, construction, and evaluation of environmental concrete and shotcrete structures for over 35 years. Hanskat is also a member of ACI  Committees 301, Specifications for Structural Concrete; 350, Environmental Engineering Concrete Structures; 371, Elevated Tanks with Concrete Pedestals; 372, Tanks Wrapped with Wire or Strand; 376, Concrete Structures for Refrigerated Liquefied Gas Containment; 506, Shotcreting; and Joint ACI-ASCE Committee 334, Concrete Shell Design and Construction. Hanskat’s service to the American Society of Civil Engineers (ASCE), the National Society of Professional Engineers (NSPE), and the Florida Engineering Society (FES) in over 50 committee and officer positions at the national, state, and local levels was highlighted when he served as State President of FES and then as National Director of NSPE. He served as a District Director of Tau Beta Pi from 1977 to 2002. He is a Fellow of ACI, ASCE, and FES and a member of ACI, NSPE, ASTM International, and ASCC. requirements of the OSHA rule, and any recommended limitations on the employee’s use of respirators. • Communicate to all workers potentially exposed to silica the health hazards associated with exposure to respirable crystalline silica, and identify all MSDS that include crystalline silica. The employer must communicate at least the potential hazards that result in cancer, lung effects, immune system effects, and kidney effects. • Provide information and training sessions that identify: work operations that could produce silica exposure; specific measures the employer implemented to protect employees from exposure to silica; the identity of the competent person; and the purpose and description of the medical surveillance program. The contractor must further ensure that each employee can demonstrate knowledge and understanding of the training. • Maintain accurate records for 30 years of: ◦◦ All exposure measurements, including name, social security number (SSN), and job classification of all employees represented by the monitoring, and indication of those employees who were actually monitored. ◦◦ Objective data including the crystallinecontaining material, the source of the data, and the testing protocol with results of the testing. ◦◦ Each employee covered by medical surveillance including name, SSN, all PLHCP reports, and information provided by employer to the PLHCP. Summary OSHA’s new rule for control of exposure to crystalline silica is intended to protect workers on our jobsites. This is one of the most comprehensive rules OSHA has promulgated, and introduced extensive medical monitoring and recordkeeping requirements that will require a significant increase in the contractor’s required duties that will certainly require more staffing to implement. In this article, most of the key points are introduced; however, extensive documentation leading to the new rule—along with FAQ and the text of the rule—are readily available at the OSHA website (www.osha.gov/silica).
