It seems like sneeze guards in Toronto appeared everywhere on or about March of 2020. However, even before COVID-19, plexiglass sneeze guards were used to protect people and products from droplets. Older uses included salad bars, high-traffic services like subway booths, and grocery stores. Today, however, the plexiglass sneeze guards in Canada are everywhere because these shields inhibit the spread of COVID-19 and keep essential workers safe. Recently, researchers at Princeton University began testing the effectiveness of plexiglass sneeze guards in the context of COVID-19. The researchers mimicked the use of the shield in a way we typically see in commercial settings, and used a fog machine to simulate droplets. The researchers found that some of the fog did get around the plexiglass sneeze guard, but this was only a result of good ventilation. Otherwise, the guards are very effective, especially if they can be used with an HVAC ventilation system. Why are Protective Shields Needed?Everybody today knows that COVID-19 spreads via respiratory droplets. The same can be said for the innumerable germs and viruses we pass around. The safest way to avoid the spread beyond avoiding others, wearing a mask, and getting vaccinated is to stay six feet away from others at all times.
For many employees, the six-foot gap is not possible or practical, so for these people, standing behind a plexiglass sneeze guard is the safest thing they can do.
