Meiden starts selling mouth shield that protects construction workers from airborne droplets
Meidensha Corporation (Meiden) today started selling a mouth shield that can easily be attached to and detached from a helmet for construction or manufacturing workers.
Demand for mouth shields is rising to stop construction workers from suffering heat stroke at a time when mask-wearing is recommended to prevent COVID-19 infection via droplets spread in the air. Meiden developed this new helmet-attachable product by modifying a commercially available mouth shield based on suggestions from would-be users, including young construction workers. Patent is pending for this product as of September 2020.
Meiden conducted experiments on the spread of droplets when a sneezer wore a mouth shield and when they did not. These experiments confirmed that the mouth shield effectively prevented droplets from scattering in the air.

<Effects of using the product>
・A mouth shield clipped to a helmet’s chin strap can effectively block frontward scatter of droplets during conversations. Also capable of blocking droplets emitted by a person in front of the wearer.
・Using the clip reduces ear pain and discomfort associated with wearing a mouth shield for many hours.
・Using the product together with air-conditioned clothing enhances comfort because a cool breeze will reach the mouth area.
・The clip can be replaced with a rubber strap when the user wears a cap or hat without a chin strap.
Meiden is dedicated to enhancing the health and safety of construction and manufacturing workers by providing products that help prevent COVID-19 infection and heat stroke.
