COVID-19: Plastic dividers broadly ineffective and even counterproductive, Ontario professional says

At first, some companies used bathe curtains or a makeshift plastic tarp to divide prospects from workers members.

Twenty months after the pandemic started, it’s virtually inconceivable to enter a restaurant, retail retailer, medical workplace, or different enterprise with out seeing protecting plastic shields separating folks.

Now, one among Ontario’s high advisors guiding the province’s pandemic response says the plastic dividers could not solely be ineffective — they might be counterproductive to public security.

“Science is evolving,” mentioned Dr. Peter Jüni, scientific director of Ontario’s COVID-10 Science Advisory Desk and professor of medication and epidemiology at College of Toronto at St. Michael’s Hospital.

“The place you see (them) in colleges or eating places, the plexiglass can impede air flow and provides folks a fallacious sense of safety,” Jüni mentioned.

The view is shared by different consultants.

“The basic drawback with a barrier is that it provides (in some circumstances) not a lot safety … what a barrier can do is it makes for poor air flow,” mentioned Jeffrey Siegel, professor of civil and mineral engineering on the College of Toronto.

“That is the suitable recommendation: I’m glad Dr. Jüni and others are saying it. I believe it’s been well-known for some time that boundaries may be a problem,” mentioned Siegel.

Neither Siegel or Jüni oppose the usage of boundaries in direct, face-face customer-service environments.

Nevertheless, they are saying the broader use of mounted plastic boundaries in public locations can inhibit air flow that’s designed to advertise higher air movement.

“There are plexiglass boundaries which are completely okay: when you’ve got a check-out counter at a espresso store. The place it’s an issue (is) the place you see (it) in colleges or eating places: there the plexiglass can impede air flow and provides folks a fallacious sense of safety,” mentioned Jüni.

“Use the plexiglass solely in conditions the place it actually is sensible.”

Siegel says whereas boundaries may also be used to restrict what number of people occupy a given house at one time, too many boundaries deployed incorrectly may be bother.

“We’re beginning to have some knowledge and the information means that … in some circumstances boundaries may be extra dangerous than useful,” mentioned Siegel.

The Canadian Federation of Impartial Enterprise informed International Information that there ought to be extra readability on the barrier difficulty.

“Relationship again to the primary wave, business tips beneficial plexiglass boundaries. Even now the laws on reopening prescribe totally different makes use of relying on the presence of bodily boundaries,” mentioned Ryan Mallough, senior director of provincial affairs for the CFIB.

“We perceive if the pondering on this has modified; nonetheless, it must be defined clearly and enterprise house owners ought to be compensated for his or her funding,” Mallough mentioned in an announcement.

However Ontario’s chief medical officer of well being, Dr. Kieran Moore, mentioned Thursday the boundaries nonetheless have worth in combating COVID-19.

“Bodily boundaries like plexiglass do have a task to play within the hierarchy of controls that lower the chance of transmission.”
