New guidance documents explain importance of testing in reducing, preventing worker exposure to respiratory hazards

National Institute for Occupational Health and Safety 

WASHINGTON – The Occupational Safety and Health Administration and the National Institute for Occupational Safety and Health (NIOSH) developed two guidance documents, one for workers and one for employers, which describe the use of spirometry testing to help reduce and prevent worker exposure to respiratory hazards.

Spirometry is a common pulmonary function test that measures how well a person moves air in and out of the lungs. Workers who inhale some types of dusts, gases or other air contaminants can, over time, experience lung damage. The spirometry test may detect breathing problems or significant changes in a worker’s lung function at an early stage. The information in these new guidance documents assists employers with identifying and eliminating hazardous workplace exposures and helping reduce or prevent the chances of workers developing lung disease.

The new OSHA-NIOSH-produced Infosheet for employers clarifies what spirometry is, when it is needed, and critical elements that employers can use to evaluate the quality of spirometry services provided to their workers. The Infosheet also describes how monitoring workers’ lung function over time can help individuals by identifying problems early and make the workplace safer by identifying when workplace respiratory hazards are causing problems that must be corrected. The companion document, OSHA-NIOSH Worker Info, explains to workers the importance of taking a spirometry test, what to do during the test, and their right to receive an explanation and copy of test results.

“Spirometry is the best available test for early detection of decreasing or abnormal lung function,” said Assistant Secretary of Labor for Occupational Safety and Health Dr. David Michaels. “Our joint effort with NIOSH in developing these products will help broaden outreach and enhance knowledge of preventive measures aimed at protecting worker health and safety.”

“We are pleased to join with OSHA in emphasizing the important role of spirometry in preventing costly, debilitating, and potentially fatal occupational lung diseases,” said NIOSH Director John Howard, M.D. “These tests are a vital component of health and safety programs in workplaces where workers may be exposed to hazardous airborne contaminants.”

OSHA also recommends spirometry testing for workers exposed to diacetyl and diacetyl substitutes. The agency recently issued a Safety and Health Information Bulletin on Occupational Exposure to Flavoring Substances: Health Effects and Hazard Controls and a companion Worker Alert on Diacetyl and Substitutes. These documents recommend that employers include spirometry testing in their medical surveillance programs to identify workers experiencing adverse health effects from exposure to flavorings, including food flavorings containing diacetyl.

Under the Occupational Safety and Health Act of 1970, employers are responsible for providing safe and healthful workplaces for their employees. OSHA’s role is to assure these conditions for America’s working men and women by setting and enforcing standards, and providing training, education and assistance.

OSHA seeks additional public comments on proposed column for employer injury and illness logs

OSHA is reopening the public record on a proposed rule to revise the Occupational Injury and Illness Recording and Reporting Requirement regulation. Notice of the reopening will be published May 17 in the Federal Register. The purpose of the reopening is to allow interested individuals to comment on the small business teleconferences OSHA and the Small Business Administration’s Office of Advocacy co-sponsored April 11-12, and on the issues raised during the teleconferences. OSHA held the teleconferences to gather information from representatives of small businesses about their experiences recording work-related musculoskeletal disorders and how they believe they would be impacted by OSHA’s proposed rule. OSHA has posted a summary of comments about the teleconferences in the public docket for this rulemaking. The proposed rule covers only MSDs that employers are already required to record under the longstanding OSHA Recordkeeping rule. Interested persons must submit comments by June 16 either electronically or by fax, mail, hand delivery, express mail, messenger or courier. See the Federal Register notice for more information.

Inner Ear Can ‘Store’ Recent Sounds, Study Finds

Vibrations in the ear continue briefly after a sound has ended, researchers say.

TUESDAY, April 5 (HealthDay News) — The inner ear can actually “store” sounds, according to a new study.

Scientists found that vibrations in the inner ear continue even after a sound has ended and may serve as a mechanical memory of recent sounds.

The study is published in the April 5 issue of the Biophysical Journal.

In research with guinea pigs, the investigators found that after-vibrations in the inner ear were dependent on the magnitude and frequency of the sound stimuli and that even minor hearing loss resulted in a major reduction in after-vibrations.

“The after-vibrations appear to be driven by sustained force production in the inner ear — a form of short-term memory of past stimulations,” study senior author Dr. Alfred L. Nuttall, of the Oregon Hearing Research Center, said in a journal news release.

“It is important to point out that although our findings clearly demonstrate the existence of after-vibrations, further work is needed to elucidate the underlying mechanism,” he added.

Nuttall explained the potential importance of after-vibrations for hearing.

“The ability to detect brief gaps in an ongoing stimulus is critical for speech recognition; gaps need to be longer than a minimal interval to be perceived. To the extent that after-vibrations excite the auditory nerve fibers, they may explain part of the difficulty in detecting such gaps.”

The U.S. National Institute on Deafness and Other Communication Disorders outlines signs of hearing loss.
