Those Anti-COVID Plastic Barriers Could Be Counterproductive

With the ongoing struggle against COVID-19, many schools and businesses are implementing plastic barriers in an attempt to curb the virus’s spread. However, recent research indicates that these transparent shields may hinder proper ventilation rather than provide effective protection.

Experts in aerosol behavior and airflow have found that these barriers often fail to prevent the transmission of the virus and can create a misleading sense of safety. In fact, they may exacerbate the situation. According to recent findings, barriers meant to protect cashiers or other workers can redirect airborne germs toward others in the vicinity. Clear plastic dividers, commonly seen in classrooms or salons, can obstruct airflow, leading to what scientists refer to as “dead zones” where virus-laden particles accumulate.

In areas without barriers, exhaled breath disperses and is replaced by fresh air approximately every 15 to 30 minutes. However, the introduction of plastic dividers disrupts this airflow, trapping respiratory droplets and increasing their concentration in enclosed spaces. Linsey Marr, a leading expert on viral transmission, emphasized that a multitude of barriers in a classroom can severely compromise ventilation, allowing aerosols to build up and spread beyond individual workspaces.

While these barriers may effectively block larger respiratory droplets, such as those from a sneeze, they are less effective against the smaller aerosol particles that primarily propagate COVID-19. Disturbingly, studies have linked plastic dividers in classrooms to higher rates of infection and shown that they impede airflow in office settings. A notable study from Johns Hopkins revealed that desk barriers in educational environments correlated with increased risks of COVID-19 transmission.

In addition, research from Britain highlights that while barriers may offer some protection when a person coughs, they do not effectively contain exhaled particles during normal conversation, which continue to circulate in the space. This underscores the importance of proper ventilation alongside other protective measures.

As organizations grapple with this information, it remains to be seen how they will adapt their safety protocols in workplaces and educational institutions.

In summary, while many establishments have turned to plastic barriers as a protective measure against COVID-19, emerging research suggests that they may not only be ineffective but could also worsen the situation by impeding airflow and trapping potentially infectious particles. Awareness of these issues is crucial for ensuring the health and safety of individuals in shared spaces.
