WAREHOUSE: DESIGN GUIDELINES FOR INFECTION CONTROL. HE N D E R S ON IN SIG HTS | COVID-19 SERI ES

Due to COVID-19, warehouses have played a crucial role in keeping the retail and grocery industries running, powering online shopping and supporting the delivery of essential goods. Now more than ever it is critical to protect the health and safety of essential workers, while keeping the facilities they work in operational. To do this, we’ve developed building systems design guidelines to help mitigate any potential spread of infection, allowing them to support the high demand being experienced by this infrastructure around the country.
