BACKGROUND: To protect both the surgeon and patient during procedures, hooded protection shields are used during joint arthroplasty procedures. Headache, malaise, and dizziness, consistent with increased carbon dioxide (CO2) exposure, have been anecdotally reported by surgeons using hoods. We hypothesized that increased CO2 concentrations were causing reported symptoms. METHODS: Six healthy subjects (4 men) donned hooded protection, fan at the highest setting. Arm cycle ergometry at workloads of 12 and 25 watts (W) simulated workloads encountered during arthroplasty...

Under the Congressional Review Act, Congress has passed, and the President has signed, Public Law 115-21, a resolution of disapproval of OSHA's final rule titled, "Clarification of Employer's Continuing Obligation to Make and Maintain an Accurate Record of each Recordable Injury and Illness." OSHA published the rule, which contained various amendments to OSHA's recordkeeping regulations, on December 19, 2016. The amendments became effective on January 18, 2017. Because Public Law 115-21 invalidates the amendments to OSHA's recordkeeping regulations contained in the rule promulgated on December 19, 2016, OSHA is hereby removing those amendments from the Code of Federal Regulations...

During 2003-2013, fatality rates for oil and gas extraction workers decreased for all causes of death except those associated with fall events, which increased 2% annually during 2003-2013 (1). To better understand risk factors for these events, CDC examined fatal fall events in the oil and gas extraction industry during 2005-2014 using data from case investigations conducted by the Occupational Safety and Health Administration (OSHA). Sixty-three fatal falls were identified, accounting for 15% of all fatal events...

Work environments are continuously changing with the introduction of new technologies, substances and work processes, changes in the structure of the workforce and labor market, and new forms of employment and work organization. New work situations bring both risks and challenges for workers and employers, which, in turn, may require political, administrative, technical, and regulatory approaches to ensure worker safety and health. This article is based on a European Agency for Safety and Health at Work (EU-OSHA) report, Green Jobs and Occupational Safety and Health, that detailed new and emerging risks to occupational safety and health associated with new technologies in green jobs...

The United States Occupational Safety and Health Administration (OSHA) Bloodborne Pathogens Standard as amended by the Needlestick Safety and Prevention Act requiring the use of safety-engineered medical devices to prevent needlesticks and sharps injuries has been in place since 2001. Injury changes over time include differences between those from non-safety compared with safety-engineered medical devices. This research compares two US occupational incident surveillance systems to determine whether these data can be generalized to other facilities and other countries either with legislation in place or considering developing national policies for the prevention of sharps injuries among healthcare personnel...

This study analyzed the Construction FACE Database (CFD), a quantitative database developed from reports of the Fatality Assessment and Control Evaluation (FACE) program conducted by the National Institute for Occupational Safety and Health (NIOSH). The CFD contains detailed data on 768 fatalities in the construction industry reported by NIOSH and individual states from 1982 through June 30, 2015. The results show that falls accounted for 42% (325) of the 768 fatalities included in the CFD. Personal fall arrest systems (PFAS) were not available to more than half of the fall decedents (54%); nearly one in four fall decedents (23%) had access to PFAS, but were not using it at the time of the fall...

OBJECTIVES: The US Occupational Safety and Health Administration (OSHA) recently proposed a permissible exposure limit of 0.2 µg/m(3) for beryllium, based partly on extrapolated estimates of lung cancer risk from a pooled occupational cohort. The purpose of the present analysis was to evaluate whether cohort members exposed at lower levels to mainly insoluble forms of beryllium exhibit increased risk of lung cancer. METHODS: We conducted Cox proportional hazards regression analyses among 75 lung cancer cases in age-based risk sets within two lower exposure plants in the pooled cohort followed from 1940 to 2005...

INTRODUCTION: A 2009 Government Accounting Office (GAO) report, along with numerous published studies, documented that many workplace injuries are not recorded on employers' recordkeeping logs required by the Occupational Safety and Health Administration (OSHA) and consequently are under-reported to the Bureau of Labor Statistics (BLS), resulting in a substantial undercount of occupational injuries in the United States. METHODS: OSHA conducted a Recordkeeping National Emphasis Program (NEP) from 2009 to 2012 to identify the extent and causes of unrecorded and incorrectly recorded occupational injuries and illnesses...

Phthalides are a relatively small group of natural compounds confined to several plant families and some genera of fungi and liverworts. They are divided into two structural groups, the monomeric and dimeric phthalides, and known mainly as bioactive constituents of different plant species used traditionally for medicinal purposes in Asia, Europe, and North America.The first reports on the chemistry of phthalides appeared at the end of the nineteenth century, in which they were identified as the odor constituents of the essential oil of celery (Apium graveolens) by Ciamician and Silber (1897)...

The Occupational Safety and Health Administration (OSHA) is amending its existing standards for occupational exposure to beryllium and beryllium compounds. OSHA has determined that employees exposed to beryllium at the previous permissible exposure limits face a significant risk of material impairment to their health. The evidence in the record for this rulemaking indicates that workers exposed to beryllium are at increased risk of developing chronic beryllium disease and lung cancer. This final rule establishes new permissible exposure limits of 0...

OSHA is amending its recordkeeping regulations to clarify that the duty to make and maintain accurate records of work-related injuries and illnesses is an ongoing obligation. The duty to record an injury or illness continues for as long as the employer must keep records of the recordable injury or illness; the duty does not expire just because the employer fails to create the necessary records when first required to do so. The amendments consist of revisions to the titles of some existing sections and subparts and changes to the text of some existing provisions...
