  • COVID-19 Guidance on the Reuse of Elastomeric (Half Mask) Respirators
    COVID-19 Guidance on the Reuse of Elastomeric (Half Mask) Respirators This guidance is adapted for use in Manitoba from materials developed by McGill University Health Centre. CONTEXT Reusable respirators (specifically, reusable half-facepiece elastomeric respirators) are the standard respiratory protection device used in many industries and in certain healthcare settings and facilities. 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. MATERIAL Elastomeric Half-Facepiece Respirators (EHFR) (see annex 1 to compare with other masks/respirators) are half-face, tight-fitting respirators made of synthetic or rubber material. These materials permit them to be repeatedly disinfected, cleaned, and reused. PROCEDURES Prior to first use all healthcare workers must be fit tested by Occupational Health and/or designate. FILTER ASSEMBLY INSTRUCTIONS 1. Align opening of cartridge/filter with filter attachment on facepiece. The alignment mark on the cartridge/filter should face the front of the facepiece. 2. Turn cartridge/filter clockwise one quarter until it is firmly seated and cannot be further turned. 3. Repeat for second filter. DONNING THE HALF-MASK (STANDARD SUSPENSION) 1. Perform hand hygiene. 2. Inspect the respirator to ensure it is in proper operating condition (not cracked, damaged, flaps are not torn or missing, straps not damaged, etc.). Jan. 4, 2021 COVID-19 Reusing and Disinfection of Elastomeric Respirators (half face respirator) 1 Adapted from McGill University Health Centre 3. Replace any damaged or defectives parts before use. 4. Adjust head cradle size as needed to fit comfortably on head.

Clinical Guidelines 1. Use of aerosol generating procedures: a. The use of aerosol generating procedures has been shown to significantly increase the risk of transmission of the virus via aerosolized particles and should therefore be limited or avoided where possible. When use of these procedures is unavoidable, airborne and contact precautions are required. This includes an N-95 respirator or PAPR, mask with visor, gown, hairnet and gloves x2. Aerosol generating procedures include the following: Mechanical ventilation • The use of active humidification is not advised. Ventilators will be set up using a dry circuit with a heat and moisture exchanger (HME) in line and a bacterial and viral filter placed at the exhalation valve. The HME must be changed every 3-4 days or as needed. Bacterial and viral filters should be changed every 4 hours, or earlier as needed. Respiratory Care Boston Medical Center Page: 2 COVID-19 Respiratory Guidelines • If the patient’s ventilatory requirements exceed the capability of an HME, active humidity must be used, keeping the bacterial and viral filter on the exhalation valve. Due to the effect of the additional moisture on the filter, it must be changed every 4 hours or as needed.

  • Balancing the Risk – Strategies for Respiratory Protection During a Pandemic
    Balancing the Risk – Strategies for Respiratory Protection During a Pandemic By Christina M. Baxter (Emergency Response TIPS) and Jeffrey O. Stull (International Personnel Protection) Responders can be exposed to the SARS-CoV-2 virus responsible for COVID-19 by inhaling aerosolized droplets from an infected individualized persons’ coughs and sneezes as well as contact with contaminated surfaces with subsequent hand transfer to the mouth, nose, or eyes. First responders may be at increased risk for exposure with potentially sick patients from increased aerosol and fluid volumes and close proximity. For this reason, extra caution in the selection, handling, and cleaning of PPE used by first responders must be exercised. This document discusses a proposed approach for balancing risk while maintaining the highest level of protective posture as the pandemic continues. Finally, there is considerable confusion in the community regarding the need for fit testing, especially as it relates to filter facepiece respirators. NIOSH released a blog post on this topic and it is worth a quick review by all (https://blogs.cdc.gov/niosh-science-blog/2020/04/01/fit-testing-during-outbreaks/). PHASE 1 (WHILE RESPIRATOR SUPPLIES ARE AVAILABLE) To reduce the risk from inhalation exposure, responders should conduct initial patient assessment from 6 feet away, or the doorway if possible. If an infectious disease is suspected, donning a respirator effective against COVID-19 is paramount. Consider minimizing the number of responders involved with specific patients to extend respirator supplies. Filtering Facepiece Respirators (FFRs) • The minimum level of respiratory protection is an N95 filtering facepiece respirator that is certified and approved by the National Institute for Occupational Safety and Health (NIOSH) per specific filtration efficiency and other requirements.

  • Respiratory Protection
    Respiratory Protection The Occupational Safety and Health Administration (OSHA) construction industry regulations relating to respiratory protection (29 CFR 1926.103) are actually found under the general industry regulations applicable to respiratory protection in 29 CFR 1910.134. Those provisions mandate respiratory protection if engineering controls are not feasible or are ineffective. OSHA requires methods such as substituting less toxic materials or ventilating the work area to prevent atmospheric contamination. When engineering controls fail to reduce employee exposures to harmful contaminants below the permissible exposure limit (PEL) of a contaminant, respiratory protection and accompanying program elements must be put in place. Written Respiratory Protection Program The OSHA respiratory standard requires contractors to develop and implement a written respiratory protection program for situations in which PELs of airborne contaminants could be exceeded or when the employer requires use of respirators by workers. See also the chapter on Confined Spaces. The written program also must address voluntary respirator use; respirator selection; medical evaluations; fit-testing; use of respirators; user seal checks; maintenance and care of respirators; identification of filters, cartridges and canisters; employee training; and program evaluation. The standard requires the respiratory program to be administered by a program administrator and updated to reflect the changing workplace conditions that affect respirator use. The standard sets out several mandatory components within the aforementioned program categories including fit testing, seal-check and cleaning procedures in addition to a medical evaluation questionnaire and voluntary-use procedures that are compiled in appendices to §1910.134. Many of the elements listed may not need to change for each project.
