NIOSH researchers involved in an effort to characterize chemical hazards in the oil and gas extraction industry have found elevated levels of silica exposure during hydraulic fracturing operations.

Here are this week’s top occupational safety and health-related stories from www.ISHN.com:

OSHA and NIOSH have recently issued a hazard alert on ensuring that employers in hydraulic fracturing operations take appropriate steps to protect workers from silica exposure.

A study on the nation’s groundwater supply released by the journal Nature is giving fracking opponents some fresh ammunition.

It’s “Truthland” versus “Gasland.” The American Petroleum Institute (API) hosted a film festival recently in Washington, D.C. during which excerpts from several pro-fracking films were screened. The event was a response to the critical-of-fracking documentary “Gasland,” by independent filmmaker Josh Fox.
