Laboratory evaluation of the particle size effect on the performance of an elastomeric half-mask respirator against ultrafine combustion particles.
OBJECTIVES This study quantified the particle size effect on the performance of elastomeric half-mask respirators, which are widely used by firefighters and first responders exposed to combustion aerosols. METHODS One type of elastomeric half-mask respirator equipped with two P-100 filters was donned on a breathing manikin while challenged with three combustion aerosols (originated by burning...
متن کاملPerformance of a full facepiece, air-purifying respirator against lead aerosols in a workplace environment.
This study evaluated workplace performance of a full facepiece, negative pressure, air-purifying respirator with P100 filters in a lead refining plant. Air samples for lead were collected inside and outside the respirators worn by workers who were properly trained and quantitatively fit tested. Trained observers assisted in the study to ensure sample validity. Three to four pairs of air samples...
متن کاملSurgical mask vs N95 respirator for preventing influenza among health care workers: a randomized trial.
CONTEXT Data about the effectiveness of the surgical mask compared with the N95 respirator for protecting health care workers against influenza are sparse. Given the likelihood that N95 respirators will be in short supply during a pandemic and not available in many countries, knowing the effectiveness of the surgical mask is of public health importance. OBJECTIVE To compare the surgical mask ...
متن کاملEvaluation of half-face respirator fit in an Iranian petrochemical company's workers
Introduction: The performance of respirator-face piece is depending on a good contact between the worker's face and the respirator. Improper sealing can cause reduction in performance of respirators to protect health and safety of workers against risks related to chemical agents at work. This study is aimed to evaluate the fitness of half-face respirators and other related factors on it in an...
متن کاملCarbon tetrachloride replacement compounds for organic vapor air-purifying respirator cartridge and activated carbon testing--a review.
This article reviews efforts by researchers and organizations around the world to identify chemicals as substitutes for carbon tetrachloride in measuring activated carbon activity (adsorption capacity) or organic vapor air-purifying respirator cartridge (or other packed carbon bed) breakthrough times. Such measurements usually are done to determine if a minimum performance standard is met. Diff...
