Worker exposure to silica during hydraulic fracturing

"Hydraulic fracturing or 'fracking' is a process used_to 'stimulate' well production in the oil and gas industry. It is not a new process, but its use has increased significantly in the last 10 years because_of new horizontal drilling and multi-stage fracking (or 'completions') technologies that improve access to natural gas and oil deposits. It involves pumping large volumes of water and sand into a well at high pressure to fracture shale and other tight formations, allowing oil and gas to flow into the well. NIOSH's recent field studies show that workers may be exposed to dust with high levels of respirable crystalline silica (called 'silica' in this Hazard Alert) during hydraulic fracturing. This Hazard Alert discusses the health hazards associated with hydraulic fracturing and focuses on worker exposures to silica in the air. It covers the health effects of breathing silica, recommends ways to protect workers, and describes how OSHA and NIOSH can help. Workers and employers need to be aware of the hazard that silica dust poses. Employers must ensure that workers are properly protected from exposure to silica. This Hazard Alert also provides a brief summary of other health and safety hazards to workers conducting hydraulic fracturing activities." - p. 1The National Institute for Occupational Safety and Health (NIOSH) identified exposure to airborne silica as a health hazard to workers conducting some hydraulic fracturing operations during recent field studies."DTSEM 6/2012."Also available via the World Wide Web as an Acrobat .pdf file (2.02 MB, 7 p.)

Use of blunt-tip suture needles to decrease percutaneous injuries to surgical personnel

"The purpose of this Safety and Health Information Bulletin is: 1. To describe the hazard of sharp-tip suture needles as a source of percutaneous injuries to surgical personnel; 2. To present evidence of the effectiveness of blunt-tip suture needles in decreasing percutaneous injuries to surgical personnel, particularly when used to suture muscle and fascia; and 3. To emphasize OSHA's requirement to use safer medical devices - in this case, blunt-tip suture needles - where clinically appropriate. Conclusion: OSHA and NIOSH strongly encourage the use of blunt-tip suture needles, whenever feasible and appropriate, to decrease percutaneous injuries to surgical personnel. Clinical use and scientific studies have established the effectiveness of blunt tip suture needles in decreasing the risk of percutaneous injuries. Employers in workplaces that use suture needles have the responsibility under the Bloodborne Pathogens standard to evaluate the use of blunt-tip suture needles as well as other appropriate safer medical devices. After this evaluation, which must include input from nonmanagerial employees responsible for direct patient care [29 CFR 1910.1030(c)(1)(v)] - e.g., in this case surgical personnel - employers must use safer devices to replace corresponding conventional sharp-tip suture needles in their workplaces when clinically appropriate. The introduction of any device must include training of staff in its proper use and follow-up to ensure a successful transition from conventional to safer devices. Where an employer has determined that the use of available safer devices is not feasible, the clinical justification for this determination must be documented in the facility's Exposure Control Plan and the employer must implement alternative means of protecting surgical personnel from percutaneous injuries.

Development and evaluation of an advanced training technology course within a union-based industrial emergency response training program

Background The Health and Safety Department of the United Automobile Workers recently introduced the use of Advanced Training Technologies (ATTs) into a previously successful Industrial Emergency Response (IER) program. The new curriculum attempted to incorporate web-based technology, while preserving the historical emphasis on the use of peer trainers and the Small Group Activity Method (SGAM) to promote team problem solving and worker empowerment. Methods The University of Michigan evaluated the program by administering a survey combining open- and closed-ended questions to trainees. Results Of the 46 respondents, most rated the program very highly, found that the use of internet technology allowed faster access to current information, reported peer trainers as one of program aspects they liked best, and did not find working in groups of three per computer difficult. Conclusions It is possible to enhance a workplace health and safety training program through the introduction of ATT without compromising participant-centered, group learning program philosophies.

Occupational cooling practices of emergency first responders in the United States: A survey

This is an accepted manuscript of an article published by Taylor & Francis in Temperature on 29/07/2018, available online: https://doi.org/10.1080/23328940.2018.1493907 The accepted version of the publication may differ from the final published version.© 2018 Informa UK Limited, trading as Taylor & Francis Group. Despite extensive documentation directed specifically toward mitigating thermal strain of first responders, we wished to ascertain the degree to which first responders applied cooling strategies, and what opinions are held by the various agencies/departments within the United States. An internet-based survey of first responders was distributed to the International Association of Fire Chiefs, International Association of Fire Firefighters, National Bomb Squad Advisory Board and the USA Interagency Board and their subsequent departments and branches. Individual first responder departments were questioned regarding the use of pre-, concurrent, post-cooling, types of methods employed, and/or reasons why they had not incorporated various methods in first responder deployment. Completed surveys were collected from 119 unique de-identified departments, including those working in law enforcement (29%), as firefighters (29%), EOD (28%) and HAZMAT technicians (15%). One-hundred and eighteen departments (99%) reported heat strain/illness to be a risk to employee safety during occupational duties. The percentage of departments with at least one case of heat illness in the previous year were as follows: fire (39%) HAZMAT (23%), EOD (20%) and law enforcement (18%). Post-cooling was the scheduled cooling method implemented the most (63%). Fire departments were significantly more likely to use post-cooling, as well as combine two types of scheduled cooling compared to other departments. Importantly, 25% of all departments surveyed provided no cooling whatsoever. The greatest barriers to personnel cooling were as follows–availability, cost, logistics, and knowledge. Our findings could aid in a better understanding of current practices and perceptions of heat illness and injury prevention in United States first responders.

The Tobacco Industry’s Role in the 16 Cities Study of Secondhand Tobacco Smoke: Do the Data Support the Stated Conclusions?

BACKGROUND: Since 1996, the tobacco industry has used the 16 Cities Study conclusions that workplace secondhand tobacco smoke (SHS) exposures are lower than home exposures to argue that workplace and other smoking restrictions are unnecessary. OBJECTIVES: Our goal was to determine the origins and objectives of the 16 Cities Study through analysis of internal tobacco industry documents and regulatory agency and court records, and to evaluate the validity of the study’s conclusions. RESULTS: The tobacco industry’s purpose in conducting the 16 Cities Study was to develop data showing that workplace SHS exposures were negligible, using these data to stop smoking restrictions by the U.S. Occupational Safety and Health Administration. The extensive involvement of R.J. Reynolds Tobacco Company and the tobacco industry’s Center for Indoor Air Research in controlling the study was not fully disclosed. The study’s definition of “smoking workplace” included workplaces where smoking was restricted to designated areas or where no smoking was observed. This definition substantially reduced the study’s reported average SHS concentrations in “smoking workplaces” because SHS levels in unrestricted smoking workplaces are much greater than in workplaces with designated smoking areas or where no smoking occurred. Stratifying the data by home smoking status and comparing exposures by workplace smoking status, however, indicates that smoke-free workplaces would halve the total SHS exposure of those living with smokers and virtually eliminate SHS exposure for most others. CONCLUSIONS: Data in the 16 Cities Study reveal that smoke-free workplaces would dramatically reduce total SHS exposure, providing significant worker and public health benefits
