Advancements in Elastomeric Respirator Technology for Use as Source Control
Respirator design is constantly improving and evolving to meet new challenges. Manufacturers have recently developed innovative NIOSH-approved elastomeric half mask respirator (EHMR) designs that both protect the wearer as well as provide adequate source control – protecting others by filtering the wearer’s exhaled air that may contain harmful viruses or bacteria. EHMRs are being used more Read More >

On this Valentine’s Day, what lessons can respirator manufacturers learn from Liz Taylor, Larry King, Lana Turner, and Mickey Rooney? Why, the importance of quality assurance, of course. All of these celebs were married eight times—for Liz and Larry, they actually tied the knot twice with the same person—but their repeated unluckiness in love Read More >
Posted on by 2 CommentsOverview of the ASTM F3407 Standard Test Method for Respirator Fit Capability
The Fundamental Importance of Fit One of the most important criteria for any filtering facepiece air-purifying respirator to be effective is that a good seal is formed between the respirator’s facepiece and the wearer’s skin. The ability to achieve this seal is called the respirator’s fitting characteristic. In 1995, when NIOSH put Title 42 Code Read More >

Construction dust can cause serious damage to workers’ health and life-threatening diseases. Construction workers can be exposed to many types of dust, such as silica, wood, and lead dust. Workplace exposure to small particles of silica dust, also known as respirable crystalline silica, can lead to serious diseases, including silicosis, a progressive lung disease marked Read More >

A recent blog discussed prolonged respirator use and the potential physiological burden that could result from the buildup of CO2 within the respirator facepiece. Heat stress is another potential stress factor that healthcare workers (HCWs) who use personal protective equipment (PPE) and their employers should be aware of in order to recognize the signs Read More >
Posted on by 1 CommentSkin Irritation from Prolonged Use of Tight-Fitting Respirators
Filtering Facepiece Respirators (FFRs) are typically used by workers, including first responders and healthcare professionals, for short, infrequent periods of time to protect against potential airborne transmissible diseases. However, during widespread respiratory infectious disease outbreaks, there may be a need to implement respirator extended use practices due to an inadequate supply of FFRs. Skin irritation Read More >
Posted on by 1 CommentConsiderations for Covering N95s to Extend Use
Introduction During times of increased demand for N95 filtering facepiece respirators (FFRs), hospitals or other medical facilities may want to protect these devices from surface contamination in order to prolong their use. When protection against surface contamination is needed, CDC recommends wearing a cleanable face shield over an N95 FFR[1]. Wearing a surgical mask or Read More >
Posted on byThe Physiological Burden of Prolonged PPE Use on Healthcare Workers during Long Shifts
Please note that this blog is specifically about respirators used by healthcare workers during long shifts and not facemasks worn as barrier control to stop the spread of COVID. Healthcare workers (HCW) and first responders often work long, physically and mentally exhausting shifts as they provide care for patients, especially during a public Read More >

When a respirator has been approved by NIOSH, the user can be confident that the device will provide the expected level of protection, as long as it fits properly and is worn correctly. But when serious outbreak conditions cause a shortage of the NIOSH-approved filtering facepiece respirators (FFRs), other reliable options must be found. When Read More >

Cuando ocurren brotes de enfermedades infecciosas, dependemos de los profesionales de atención médica para que cuiden a los afectados, lo cual los pone en mayor riesgo de exposición al patógeno causante de la enfermedad. Mientras que los controles técnicos y administrativos deberÃan ser lo primero que se considere para proteger a estos trabajadores de la Read More >
Posted on byRespiratory Protection During Outbreaks: Respirators versus Surgical Masks
Consistent use of respirators improves protection against respiratory illness Consistent use of personal protective equipment (PPE) is an important part of the strategy to protect healthcare professionals from inhaling infectious particles, preventing the spread of respiratory infection between healthcare professionals and patients. Two types of devices are most commonly used in the healthcare setting: N95 Read More >
Posted on byThe Need for Fit Testing During Emerging Infectious Disease Outbreaks
Proper respirator use is essential for healthcare workers who are expected to interact with patients with infectious respiratory diseases. The Occupational Safety and Health Administration (OSHA) requires healthcare facilities to maintain a respiratory protection program that specifies requirements such as annual fit testing, medical clearance, and training. Initial fit testing is required before using a Read More >
Posted on byProper N95 Respirator Use for Respiratory Protection Preparedness
When outbreaks of infectious disease occur, we rely on healthcare professionals to care for those affected, putting themselves at increased risk of exposure to the pathogen causing the disease. While engineering and administrative controls should be the first considerations to protect these workers from this exposure, facilities should also ensure that at-risk employees are prepared Read More >
