Appareils de protection respiratoire et risques biologiques
Dans certains secteurs d'activité (soins, laboratoires, biotechnologies, élevage, abattoirs, assainissement...), les personnels peuvent être exposés à des agents biologiques transmissibles par voie respiratoire. Cette fiche indique les critères de choix et les conditions d'utilisation des appareils de protection respiratoire (APR). Source: http://www.inrs.fr/media.html?refINRS=ED%20146
Respirator use and its impact on particulate matter exposure in aluminum manufacturing facilities
Objectives: As part of a large epidemiologic study of particulate health effect, this study aimed to report respirator use among total particulate matter (TPM) samples collected in a major aluminum manufacturing company from 1966‒2013 and evaluate the impact of respirator-use adjustment on exposure estimation. Methods: Descriptive analyses were performed to evaluate respirator use across facilities and by facility type and job. Protection factors were applied to TPM measurements for recorded respirator use. Estimated TPM exposure for each job ‒ before and after respirator-use adjustment ‒ were...
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...
NIOSH Updates Software for Estimating Respirator Service Life
The NIOSH MultiVapor™ tool has been updated and posted to the web. MultiVapor™ is a computer tool for estimating breakthrough times and service lives of air-purifying respirator cartridges for removing toxic organic vapors from breathed air. It can also be used for larger filters and for carbon beds of any size prepared for laboratory studies. MultiVapor™ 2.2.3 replaces the 2.1.3 version.

Experimental and modeling study of thermal exposure of a self-contained breathing apparatus (SCBA)
An experimental apparatus designed to study firefighter safety equipment exposed to a thermal environment was developed. The apparatus consisted of an elevated temperature flow loop with the ability to heat the air stream up to 200°C. The thermal and flow conditions at the test section were characterized using thermocouples and bi-directional probes. The safety equipment examined in this study was a self-contained breathing apparatus (SCBA), including a facepiece and an air cylinder. The SCBA facepiece was placed on a mannequin headform and coupled to a breathing simulator that was programmed...
Effects of air bottle design on postural control of firefighters
The purpose of this study was to investigate the effect of firefighter's self-contained breathing apparatus (SCBA) air bottle design and vision on postural control of firefighters. Twenty-four firefighters were tested using four 30-minute SCBA bottle designs that varied by mass and size. Postural sway measures were collected using a forceplate under two visual conditions (eyes open and closed) and two stance conditions (quiet and perturbed stances). For perturbed stance, a mild backward impulsive pull at the waist was applied. In addition to examining center of pressure postural sway measures...
Component Analysis of Respirator User Training
Respirators must be properly used to be effective. In an experimental protocol, 145 subjects were trained and then observed donning and doffing respirators. Filtering facepiece and dual cartridge half face mask types were studied. Subjects were then tested for knowledge and for proper performance using video recording analysis. Knowledge tests showed adequate learning, but performance was often poor. Inspection, strap tension (half mask), seal checking, and avoiding mask contact during doffing were particularly problematic. Mask positioning was generally well done. Correlation between knowledge...
Mesure des facteurs de protection des appareils de protection respiratoire vis-à-vis des nanoparticules
L’utilisation des nanoparticules dans l’industrie a augmenté de manière spectaculaire ces dernières années. Les particules de taille nanométrique pourraient donc être à l’origine de nouvelles situations d’exposition professionnelle. Du fait de leur taille, celles-ci peuvent se déposer dans les voies respiratoires et pourraient même atteindre le système nerveux via les voies nasales de sorte que le port d’Appareils de Protection Respiratoire est généralement préconisé dans...
Factors influencing the implementation of RPE programmes in the workplace
This report sets out the findings from a qualitative study examining respiratory protective equipment (RPE) programmes across industry. Managerial decision-making was the focal point for this research given that decisions about RPE programmes rest with management. This cross-sector, exploratory study set out to address research on: what current RPE selection and use looks like; how this compare with 'good practice' and what factors influence choice and implementation of RPE programmes.
