The U.S. Department of Labor's Occupational Safety and Health Administration will host a live Web chat to discuss the agency's proposed rule on occupational exposure to respirable crystalline silica from 1 p.m. - 3:30 p.m. EST, Tuesday, Jan. 14. Visit http://www.osha.gov/silica/webchat.html to participate.

The Web chat will provide participants the opportunity to ask questions, get clarification from OSHA on the proposed silica rule and learn how to participate in the regulatory process. OSHA staff will be available to clarify the proposed standards related to silica for general industry, maritime and construction. Staff will also answer questions on OSHA's underlying analysis of health risks, potential costs and benefits, and economic impacts associated with the proposed rule and how to submit comments to the rulemaking record.

The deadline to submit written comments and testimony on the proposal is Monday, Jan. 27. Members of the public may submit comments by visiting http://www.regulations.gov.
