In Search of a Performing Seal: Rethinking the Design of Tight-Fitting Respiratory Protective Equipment Facepieces for Users With Facial Hair
Background: Air-purifying, tight-fitting facepieces are examples of respiratory protective equipment and are worn to protect workers from potentially harmful particulate and vapors. Research shows that the presence of facial hair on users' face significantly reduces the efficacy of these devices. This article sets out to establish if an acceptable seal could be achieved between facial hair and the facepiece. The team also created and investigated a low-cost “pressure testing” method for assessing the efficacy of a seal to be used during the early design process for a facepiece designed...
Assessment of respirator fit capability test criteria for full-facepiece air-purifying respirators
An ASTM International subcommittee on Respiratory Protection, F23.65 is currently developing a consensus standard for assessing respirator fit capability (RFC) criteria of half-facepiece air-purifying particulate respirators. The objective of this study was to evaluate if the test methods being developed for half-facepiece respirators can reasonably be applied to nonpowered full-facepiece–air-purifying respirators (FF–APR). Benchmark RFC test data were collected for three families of FF–APRs (a one-size-only family, a two-size family, and a three-size family). All respirators...

Chemical, Biological, Radiological, and Nuclear (CBRN) Respiratory Protection Handbook
Since 2001, the U.S. Department of Health and Human Services (HHS), Centers for Disease Control and Prevention (CDC), National Institute for Occupational Safety and Health (NIOSH) has established performance and design standards for respiratory protective devices (RPDs) to protect against chemical, biological, radiological, and nuclear (CBRN) hazards and toxic industrial chemicals. Prior to 2001, there were no standards for the use of RPDs by U.S. emergency response personnel that covered the full range of expected CBRN threats. Federal regulations require emergency response personnel to use respirators...
A Pilot Study of Nanoparticle Levels and Field Evaluation of N95 Filtering Facepiece Respirators on Construction Sites
Little attention has been paid to the generated submicron ultrafine and nanoparticles and their exposure levels on construction jobsites. This information is needed because cytotoxicity of nanoparticles is well known now. In addition, the performance of particulate respirators generally used by construction workers has never been evaluated in field conditions against ultrafine and nano-sized particles. We hypothesized that workers on construction jobsites are exposed to high levels of nanoparticles and current NIOSH-recommended N95 respirators may not provide them adequate protection against aerosolized...

Market surveillance of FFP3 disposable respirators
Filtering Facepieces (FFPs) are disposable Respiratory Protective Equipment (RPE) for protection against dusts, particles and aerosols. They are often referred to as 'disposable dust masks', are widely used, and generally require no cleaning or maintenance. They are available in three classes: FFP1, FFP2 and FFP3, with the higher numbers corresponding to better filtering efficiency. As with all types of Personal Protective Equipment (PPE) sold in the UK, they must comply with the EU PPE Directive 89/686/EEC. It is the responsibility of the manufacturer or person placing the RPE on the European...
Évaluation de l’efficacité d'un filtre N95 contre des particules ultrafines, dont les nanoparticules, en mode de débits d'air constant et cyclique simulant la respiration des travailleurs
On trouve des particules ultrafines (PUF), soit des particules dont le diamètre (Dp) est inférieur à 100 nm, dans de nombreux milieux de travail industriels, où leur inhalation peut, à long terme, causer de graves problèmes de santé. Dans certains contextes, les mesures d'ingénierie et les contrôles administratifs sont insuffisants pour protéger adéquatement les travailleurs contre l'exposition aux PUF. Un dispositif de protection personnel est alors requis, et les appareils de protection respiratoire à pièce...
Effectiveness of N95 respirators versus surgical masks in protecting health care workers from acute respiratory infection
A systematic review and meta-analysis Background: Conflicting recommendations exist related to which facial protection should be used by health care workers to prevent transmission of acute respiratory infections, including pandemic influenza. We performed a systematic review of both clinical and surrogate exposure data comparing N95 respirators and surgical masks for the prevention of transmissible acute respiratory infections. Methods: We searched various electronic databases and the grey literature for relevant studies published from January 1990 to December 2014. Randomized controlled trials...
Performance of Facepiece Respirators and Surgical Masks Against Surgical Smoke
Simulated Workplace Protection Factor Study Objective: Surgical smoke generated during electrocautery contains toxins which may cause adverse health effects to operating room (OR) personnel. The objective of this study was to investigate the performance of surgical masks (SMs), which are routinely used in ORs, more efficient N95 surgical mask respirator (SMRs) and N100 filtering facepiece respirator (FFRs), against surgical smoke. Methods: Ten subjects were recruited to perform surgical dissections on animal tissue in a simulated OR chamber, using a standard electrocautery device, generating surgical...
Ebola Care and Lack of Consensus on Personal Protective Respiratory Equipment
The Ebola epidemic in West Africa presents a considerable occupational risk to the health personnel involved. The principal mode of virus transmission to health care personnel is through direct contact with the patient, although transmission by aerosols through the air may also occur. Many safety protocols have been suggested relating to personal protection and particularly respiratory protection. It is generally agreed that all health care workers should have easy access to personal protective equipment. However, the degree of respiratory safety escalates from a mask, to an adequate respirator...

New NIOSH Study Supports the OSHA Annual Fit Testing Requirements for Filtering Facepiece Respirators
Results of a recently completed NIOSH study confirm the necessity of the current Occupational Safety and Health Administration (OSHA) respirator fit testing requirement, both annually and when physical changes have occurred. The study's conclusions emphasize that respirator users who have lost more than 20 pounds should be re-tested to be sure that the current size and model of respirator in use still properly fits. For over three years, NIOSH researchers followed a cohort of 229 subjects measuring N95 filtering facepiece respirator (FFR) fit and physical characteristics (e.g., face size, weight...
Disinfection of personal protective equipment for management of Ebola patients
Bessesen et al highlight the potential utility of reusable elastomeric face masks to bypass the risk of N95 respirator shortages during a respiratory illness pandemic and stress the importance of efficacious disinfection to reuse facial protective equipment safely.1 We would like to take the opportunity to underline the need that awareness on personal protective equipment (PPE) stocks is included in any pandemic preparedness plan. The demand for PPE must be established on the basis of the health care facility's role, defined by public health authorities to create a coordinated network approach...
Investigation into exposure when the visor of air fed RPE is raised during spraying
Air-fed visors (AFV) are commonly used within the Motor Vehicle Repair (MVR) trade for protection against exposure to isocyanate paints. However, a common practice amongst paint sprayers is to flip up the visor of their AFV immediately after spraying to check the quality of the paint finish. This may be only for a few seconds but if repeated numerous times during a work shift, this could potentially result in a significant increase in exposure. The aim of this project was to determine the reduction in protection and thus potential increase in exposure when the visor is lifted and to explore potential...
Developing a Performance Standard for Combination Unit Respirators
Workshop in Brief Combination unit respirators, a respirator that employs the technology of two or more types of respiratory protection, are presently used in the United States by some law enforcement and military units to respond to situations in which there are unknown and potentially dangerous respiratory hazards; they also have some industrial uses and potential for use in emergency response. On April 30, 2015 the Institute of Medicine hosted a workshop to explore the standards and research issues relevant to these respirators and their certification by the National Personal Protective Technology...
The effect of wearer stubble on the protection given by Filtering Facepieces Class 3 (FFP3) and Half Masks
HSE Inspectors routinely come across workers with various degrees of stubble growth using respiratory protective masks, despite guidance to the contrary. This research studied the effect of 0-7 days stubble growth on the protection given by FFP3 filtering facepieces and half masks. Fifteen male volunteers took part, each testing four masks. For most, three different design FFP3 and one half mask were tested, selected from seven models of FFP3 and 2 half masks. Fit tests were carried out immediately after shaving and repeated six times during the following week, without further shaving. Results...
