MSHA Issues Final Rule on Respirable Coal Mine Dust
Released by MSHA on April 23 the respirable coal mine dust standard is effective on August 1, 2014. The new rule lowers the exposure limit from 2.0 to 1.5 milligrams per cubic meter of air (mg/m³) at underground and surface coal mines. The rule also lowers the existing limit of 1.0 mg/m³ to 0.5 mg/m³ for intake air at underground mines and for miners who show evidence of developing pneumoconiosis. The rule includes a two-year phase-in period to allow mine operators adequate time to comply with MSHA's proposed respirable dust standards. Click here to read the final rule in it's entirety.
OSHA's Next Step on Silica...
Public Hearings concluded on April 4, 2014 for the proposed rule on Respirable Crystalline Silica. OSHA will publish a transcript of the hearings in the rulemaking docket. Those who participated in the hearings are able to submit additional comments. The agency received more than 1,900 comments on its proposal via the docket page on Regulations.gov, and heard from many stakeholders in person over the course of the hearings.
OSHA's NPRM for respirable crystalline silica was published in the Sept. 12 issue of the Federal Register. The proposed rule includes a new proposed permissible exposure limit (PEL) for respirable crystalline silica: 50 micrograms per cubic meter of air calculated as an eight-hour TWA. In addition, the proposal details widely used methods for controlling workers' exposure to crystalline silica, conducting medical surveillance, and training workers about silica-related hazards.

NIOSH - Chemotherapy Drug Surface Contamination in an Infusion Center (Bureau Veritas' participation is referenced on page 2 of the NIOSH report)
NIOSH issued a Health Hazard Evaluation Report (HHE) for exposure to chemotherapy drugs in an infusion center in March 2014 (Report No. 2013-0019-3205). The report addressed a request from a regional hospital where the employer was concerned about adverse health effects to employees handling chemotherapy drugs. NIOSH found detectable levels of chemotherapy drugs in surface wipe samples throughout the center. Click here to read the full NIOSH report.
ChemoAlert™ - Surface Contamination Wipe Kit
USP <797> recommends environmental sampling to detect uncontained hazardous drugs at least every 6 months or as needed to verify containment. Independent from the NIOSH study, Bureau Veritas has developed a ChemoAlert™ Surface Contamination Wipe Kit to measure surface contamination for 45 chemotherapy drugs.

Isocyanates - A Sampling Primer
Isocyanate sampling can be rather complicated and intimidating with all of the available methods and media options. For successful method selection, today’s hygienist must educate themselves on the type of process they will be sampling prior to selecting a method. After determining the isocyanates to be tested, evaluate the atmosphere where collection will occur. Are the isocyanates in a vapor or aerosol form or both? Read More
