Fate and Transport of Indoor Microbiological Aerosols (FaTIMA)

Description:

A new online tool from the National Institute of Standards and Technology is intended to help curb airborne transmission of SARS-CoV-2 – the coronavirus that causes COVID-19.

Developed by air quality experts at NIST, the free tool estimates exposure to potentially infectious aerosols in indoor spaces.

Quick Tips to Increase Ventilation at Indoor Construction Sites Without Operating HVAC Systems

Description:

COVID-19 is airborne and spreads faster and further in enclosed areas than outdoors. As temperatures drop, construction work is moving inside, work areas are being enclosed, and temporary warm-up stations are being set up. Since ventilation guidance issued by OSHA, the CDC, and other organizations largely focuses on workplaces with working HVAC systems, these are some suggestions on how to improve ventilation on construction sites.
