Control: Increase ventilation

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.

Ventilation and Air Quality for Reducing Transmission of COVID-19

Description:

Because good ventilation and indoor air quality are important in reducing airborne exposure to viruses, this guidance outlines methods for decreasing the number of viral particles in indoor air by increasing the intake of outdoor air and/or through effective air filtration.

OSHA: COVID-19 Control and Prevention - Construction Work

Description:

This OSHA guidance supplements its general, interim guidance for all workers with potential occupational exposure to SARS-Co-V-2. It is for construction employers and workers, such as those engaged in carpentry, ironworking, plumbing, electrical, heating/ ventilation/air conditioning/ventilation, masonry and concrete work, utility construction work, and earthmoving activities.
