This book was released on 2017-11-18 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Respiratory Devices for Protection Against Certain Pesticides Respirator cartridges usually contain an absorbing material such as acti vated charcoal. All the respirators listed in this report also have efficient filters, which remove dust and spray particles and thus prolong the life of the absorbing material. Gas-mask canisters always contain more absorbing material and filters with longer life than the respirator cartridges. The volume of chemical - absorbing cartridges and gas-mask canisters ranges from 50 to 100 ml. (usually the latter) for cartridges, 180 to 500 ml. For chin style canisters, and 750 to ml. For chest-type canisters. Cartridges and chin - style canisters have a shorter useful life than regular canisters because of the smaller volume of absorbing material in them.

This book was released on 1990 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: A worker's exposure to airborne contaminants can be measured by several methods. This research attempted to determine occupational exposure from the amount of contaminant deposited on respirator cartridges. The flowrate through the respirator was estimated by existing ergonomic and respiratory ventilation models. The respirator concentrations were compared with simultaneous breathing zone air samples. A respiration flow model was modified into 18 different variations depending on (1) the increase in oxygen required per increase in workload; (2) estimate of total ergonomic workload; and (3) the basal metabolic rate. Models were rejected if the required flowrate of oxygen exceeded the calculated maximum possible flowrate. Seven dust/mist samples and five organic vapor samples were taken during sanding and spray painting operations. Of the 18 models only 5 were acceptable. Dust/mist respirator results were 1.5 to 2.2 times less than the breathing zone samples. The results of organic vapor respirator cartridges did show countenance for this procedure in screening workplace exposures or estimating a respirator workplace protection factor.

This book was released on 2019-04-15 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: Protecting the health and safety of health care workers is vital to the health of each of us. Preparing for and responding to a future influenza pandemic or to a sustained outbreak of an airborne transmissible disease requires a high-level commitment to respiratory protection for health care workers across the wide range of settings in which they work and the jobs that they perform. Keeping health care workers healthy is an ethical commitment both in terms of addressing the occupational risks faced by health care workers and of providing for the continuity of patient care and services needed to maintain the health of individuals and communities. During a public health emergency, challenges will arise concerning the availability of respiratory protective devices (i.e., respirators). Reusable respirators (specifically, reusable half-facepiece elastomeric respirators) are the standard respiratory protection device used in many industries, and they provide an option for use in health care that has to date not been fully explored. The durability and reusability of elastomeric respirators make them desirable for stockpiling for emergencies, where the need for large volumes of respirators can be anticipated. However, they are used infrequently in health care. Reusable Elastomeric Respirators in Health Care explores the potential for the use of elastomeric respirators in the U.S. health care system with a focus on the economic, policy, and implementation challenges and opportunities. This report examines the practicability of elastomeric use in health care on a routine basis and during an influenza pandemic or other large aerosol-transmissible outbreak, when demand for respiratory protective devices by U.S. health care personnel may be larger than domestic supplies. The report also addresses the issues regarding emergency stockpile management of elastomeric respiratory protective devices.

Download or read book Reusability of Facemasks During an Influenza Pandemic written by Institute of Medicine and published by National Academies Press. This book was released on 2006-08-24 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Any strategy to cope with an influenza pandemic must be based on the knowledge and tools that are available at the time an epidemic may occur. In the near term, when we lack an adequate supply of vaccine and antiviral medication, strategies that rely on social distancing and physical barriers will be relatively more prominent as means to prevent spread of disease. The use of respirators and facemasks is one key part of a larger strategy to establish barriers and increase distance between infected and uninfected individuals. Respirators and facemasks may have a role in both clinical care and community settings. Reusability of Facemasks During an Influenza Pandemic: Facing the Flu answers a specific question about the role of respirators and facemasks to reduce the spread of flu: Can respirators and facemasks that are designed to be disposable be reused safely and effectively? The committee-assisted by outstanding staff-worked intensively to review the pertinent literature; consult with manufacturers, researchers, and medical specialists; and apply their expert judgment. This report offers findings and recommendations based on the evidence, pointing to actions that are appropriate now and to lines of research that can better inform future decisions.
