Summary
Sneeze guards can be placed between two people to prevent transmission of a disease resulting from a direct contact like a sneeze or cough. These physical barriers are typically placed in reception areas, cashier stations, and near uncovered food; however, with the onset of the COVID-19 pandemic, barriers are utilized in nearly all types of building including educational, manufacturing, and office facilities. Sneeze guards are made of plastic or glass for ease of accessibility, but also for easy disinfection. The CDC and WHO both recommend the use of sneeze guards between customers and employees.
Implementation
There are few limits to the placement of sneeze guards as long as necessary interactions can still be performed (e.g. money exchange). There are three primary types of sneeze guards: freestanding,hanging, and attachment to existing objects like cubicle walls or school desks.
Sustainability
Sneeze guards do not need to be regularly replaced unless they are damaged. Surfaces that are scratched should also be replaced to avoid microbial growth within scratches or dents that may be harder to disinfect. All objects, including sneeze guards, that are within the human breathing zone should be regularly cleaned with antimicrobial disinfectants.
The quality and cost of sneeze guards ranges widely. Thin, personal dividers can cost as little as a couple dollars, whereas thicker, larger plastic shields range from $50 to $100. Quality glass barriers, such as those used in banks or food service, will cost upwards of $150.
Plastic barriers should be disinfected and reused when possible to reduce the environmental impact of plastic consumption. Glass barriers tend to be of higher quality, scratch resistant, and more environmentally friendly.
