The guidance - it is NOT a standard or regulation - includes recommended actions to reduce the risk of exposure to COVID-19.
Employers of workers engaged in construction (such as carpentry, ironworking, plumbing, electrical, heating/air conditioning/ventilation, utility construction work, and earth-moving activities) should remain alert to changing outbreak conditions, including as they relate to community spread of the virus and testing availability. In response to changing conditions, employers should implement coronavirus infection prevention measures accordingly.
The webpage includes information regarding:
Using physical barriers, such as walls, closed doors, or plastic sheeting, to separate workers from individuals experiencing signs or symptoms consistent with the coronavirus;
Keeping in-person meetings (including toolbox talks and safety meetings) as short as possible, limiting the number of workers in attendance, and using social distancing practices;
Screening calls when scheduling indoor construction work to assess potential exposures and circumstances in the work environment before worker entry;
Requesting that shared spaces in home environments where construction activities are being performed, or other construction areas in occupied buildings, have good air flow; and
Staggering work schedules, such as alternating workdays or extra shifts, to reduce the total number of employees on a job site at any given time and to ensure physical distancing.
