INTRODUCTION Scope This program sets forth accepted practices for respirator users, and provides information and guidance on proper selection, use and maintenance of respirators. Purpose The purpose of this program is to ensure that the Bureau of Forensic Services Respiratory Protection Program provides guidance to all employees using respiratory protection. This program applies to all job related respiratory hazards encountered both in the field and in the laboratory with the exception of clandestine drug labs. Respiratory Protection requirements for response to clandestine drug labs are found in the BFS/BNE Clandestine Laboratory Manual for Instruction and Procedure. Permissible Practice When working in an environment containing harmful dusts, fumes, sprays, mist, fogs, smokes, vapors or gases, the primary method of protection for employees will be engineering control. -

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. -
COVID-19 O2 and Bag Guidelines Updated 4 14
Boston Medical Center Page: 1 COVID-19 Respiratory Guidelines Airway and Oxygenation Guidelines for Persons Under Investigation (PUI) or Confirmed Positive for COVID-19 ______________________________________________________________________________ Purpose: This interim guidance is for respiratory therapists and other healthcare staff caring for patients with confirmed infection with COVID 19, as well as persons under investigation for COVID-19 and is specific to that patient population only. 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. -

(PPE) When Caring for Patients with Confirmed Or Suspected COVID-19
Use Personal Protective Equipment (PPE) When Caring for Patients with Confirmed or Suspected COVID-19 Before caring for patients with confirmed or suspected COVID-19, healthcare personnel (HCP) must: • Receive comprehensive training on when and what PPE is necessary, how to don (put on) and doff (take off) PPE, limitations of PPE, and proper care, maintenance, and disposal of PPE. • Demonstrate competency in performing appropriate infection control practices and procedures. Remember: • PPE must be donned correctly before entering the patient area (e.g., isolation room, unit if cohorting). • PPE must remain in place and be worn correctly for the duration of work in potentially contaminated areas. PPE should not be adjusted (e.g., retying gown, adjusting respirator/facemask) during patient care. • PPE must be removed slowly and deliberately in a sequence that prevents self-contamination.

However, they have additional maintenance requirements which also include cleaning and disinfection of the face piece components such as straps, valves, and valve covers.
