Cleaning & Disinfecting Procedures

Ontario Public Health’s guide for Cleaning and Disinfection for Public Settings provides information on types of cleaners, frequency of cleaning and other resources to inform your venue’s operations and the development of your COVID-19 protocols.

For all individuals using cleaning and disinfecting chemicals:

  • Generic WHMIS training must be in place
  • Specific WHMIS training for each chemical used must be in place including training on the manufacturer’s instructions
  • PPE required by the manufacturer must be worn
  • Caution should be used around technical and production equipment such as microphones and headphones; it is important that cleaning procedures follow the manufacturer’s instructions as this will increase the likelihood of a thorough cleaning while not damaging the equipment or voiding a warranty

Depending on resources, a venue may want to disinfect the theatre seats between each performance as this may help limit the spread of COVID-19 and has the added benefit of potentially increasing audience confidence in a venue’s cleanliness. Options to disinfect the seats may include:

  • Disinfecting the hard surfaces areas while leaving upholstered areas
  • Disinfecting the entire seat with an electrostatic sprayer
  • With limits on audiences capability, it may be practical to create seat covers that get laundered between performance for the limited seats in use
  • If the auditorium does have upholstered seats and programming allows for one to three days between performances, this time may allow the virus to die on its own. While there have been limited studies that look at how long COVID-19 will last on surfaces, at least one study suggests the length of time the virus will survive on a surface depends on the material (copper, 4 hours; cardboard, 24 hours; plastics and stainless steel, 2-3 days)
