Policy Statement

The City of Toronto is committed to providing and maintaining a healthy and safe working environment by observing the hierarchy of controls: substitution or elimination of a product with one of a lesser toxicity, engineering controls, administrative practices and personal protective equipment.

Whenever work-related exposure to airborne contaminants (e.g. dusts, fumes, mists, bioaerosols, gases, vapours) cannot be controlled by means of elimination/substitution, engineering (e.g. ventilation) or work practice administration, or when engineering controls are being instituted, shutdown for repair/ maintenance or in event of an emergency, respiratory protective devices will be used for employee protection. Issuance and use of respiratory protective devices shall be in keeping with requirements of a respiratory protection program.


This policy applies to all City employees who are required to wear a respirator to protect against airborne contaminants to which they may be exposed during the course of their work. It also applies to employees that are provided respirators because they voluntarily choose to use a respirator for reasons of comfort or odour relief, although the workplace does not place them at risk of exposure beyond occupational exposure limits.


All City of Toronto Divisions with situations in which respiratory protective devices are used for protection against exposure to potentially hazardous environments, such as oxygen-deficiency or airborne contaminants (dusts, fumes, mists, gases, vapours, bioaerosols) or for reasons of odour relief, comfort etc. will develop and implement, in consultation with users, a written Respiratory Protection Program.

The program will be in keeping with the Occupational Health and Safety Act and its associated regulations, as well as current accepted industry standards such as the Canadian Standards Association – Z94.4-11 – Selection, Use and Care of Respirators. Program elements will include hazard assessment; respirator selection and issuance; cartridge change out schedules (if cartridges are used); fit testing; medical surveillance; equipment cleaning, storage, inspection and maintenance; training and program evaluation.

Respirator selection appropriate for the task and work location will be based on assessment of the airborne hazard by a qualified person. Only NIOSH approved respirators will be issued.

All employees assigned to a task or work area requiring the use of a tight-fitting face-piece respirator must be fit tested. Fit testing also applies to voluntary uses of a tight-fitting respirator. Fit-testing will be performed prior to issuance of a respirator and every two years thereafter for all users, and only when there are no medical conditions preventing the use of a respirator and no interferences with the respirator-face seal.

A process must be established to ensure that employees are medically fit to wear a respiratory protective device. This may be achieved either by:

  • Having all employees assessed by a health care professional prior to fit testing and respirator use to confirm whether they are medically fit to wear respirators, or
  • Having employees complete a self declaration form prior to fit testing and respirator use (see samples in tool kit attached) in which they are asked to identify whether there are potential health issues that preclude them wearing a respirator. When there is doubt about the fitness or ability of the person to wear a respirator, the employee who is required to use respirators will seek review by a physician.

When an employee is deemed by a physician to be unfit to wear a tight-fitting respirator, attempts will be made to look at appropriate alternative types of respirators that are not tight fitting. When an employee is deemed by a physician to be unfit to wear any type of respirator, the employee will be assigned tasks not requiring the use of a respirator.

Users of a tight-fitting respirator must be clean-shaven where the respirator-face piece seals to the skin when using the respirator. For employees who cannot be clean shaven for religious reasons and where the use of a respirator is an integral part of their work, attempts will be made to look at appropriate alternative types of respirators that are not tight fitting.

Prior to issuance of a respirator and at least every two years thereafter, a person must receive training on the use, limitations and care of the respirator, and be fit tested. All records of respirator fit-checks and training will be maintained by the division issuing the respirator.

Compressed breathing air and air compressors used for supplied-air respirators or self contained breathing apparatus shall comply with CSA Standard Z180.1-M85.


Senior management of a division with situations (tasks or work areas) requiring respiratory protection will:

  • Designate a qualified person as the program administrator.
  • Ensure that tasks or work areas requiring use of respiratory protection has been assessed and documented, and respirator type required for the task or work area identified
  • Ensure that resources for employee training, fit-testing and respiratory protective equipment are made available.
  • Conduct review of the respiratory protection program on a routine basis

Supervision will:

  • Identify situations or work areas where respirators may be required and ensure an assessment of the hazard is conducted
  • Communicate areas or job tasks where respiratory protection is required based on the assessment, and provide the appropriate respiratory protective device to employees
  • Consult with appropriate staff, when necessary, in assisting with hazard assessments, respirator selection, medical clearance
  • Ensure that only employees who have been health screened, fit tested and trained are issued respirators.
  • Ensure that workers use only those respirators for which they have been qualified via fit testing
  • Ensure respirators are cleaned, sanitized, inspected, maintained, repaired and stored in accordance with written instructions and manufacturer’s recommendations.
  • Conduct periodic random inspections of work areas where respirators are worn to ensure that the correct respirators are being used and that they are being worn in accordance with instructions and training received and safe operating procedures.
  • In the case of tight-fitting face piece, ensure users maintain their required clean-shaven condition and don’t have objects or materials that will interfere with the seal or operation of the respirator.
  • Make available the necessary filters/cartridges and respirator models for which employees have been fit tested
  • Provide details of type of respirator selected and anticipated work condition to health care professional conducting medical assessment.
  • Notify program administrator of user’s concerns, changes in processes, equipment, or operating procedures.
  • Notify program administrator of investigation report that revealed that the use of a respirator may have prevented or contributed to an incident or injury.

Program Administrator will:

  • Arrange and co-ordinate sessions for training and fit testing
  • Maintain list of activities and work areas determined by hazard assessment requiring the use of a respirator and the type of respirator required
  • Ensure that the respiratory protection program addresses health screening, fit testing and training of those who are to wear respirators.
  • Maintain documentation related to the fitness of respirator users to wear a respirator
  • Advise Management of any changes or gaps respecting program elements
  • Maintain records of trainingand fit testing of all respirator users including those employees who choose to wear a respirator
  • Ensure that a cartridge change out schedule is developed and implemented for areas where chemical cartridges are used

Respirator Users will:

  • Wear and use the appropriate fit-tested respirator in accordance with the instructions and training received
  • For tight-fitting face piece, maintain clean-shaven condition where the respirator contacts the face and refrain from having any object or material that would interfere with the seal or operation of the respirators.
  • Check that the respirator is clean and in good operating condition.
  • Perform a negative and/or positive pressure user seal-check each time prior to entering area of concern
  • Remove from service a respirator that is defective and report it to supervisor.
