Good results from CO2 monitoring


Some of you may know that we've been doing some air monitoring for carbon dioxide (CO2). Based on available information, aerosols can carry the coronavirus (SARS CoV-2). Aerosols can remain airborne for long periods of time, so a correlation has been made between CO2/aerosols and ventilation and potential exposures. The lower we can keep CO2 levels, the lower we expect aerosols to be within our facilities. Add to this our PPE policy regarding face coverings, good hygiene, and physical distancing, and we are meeting all of the most current recommendations to minimize exposures to SARS CoV-2.

Please read through the attached report for Priest Rapids Dam. More reports will be coming out for our different facilities. We will continue this monitoring as workers return to PUD facilities (see Dave Ponozzo's email earlier today for more information on that outlook).

The Safety Department has done this with support from Facilities, IMT, and Management. Also, if you weren't aware, Facilities increased ventilation starting back in March, which turned out to be a great move right out of the gate. Obviously with all of the smoke recently, challenges remain in making sure our ventilation throughout the PUD is sufficient to provide a comfortable work space for our employees.

If you have any questions regarding this report, please feel free to contact me or your local Safety Coordinator.

Thank you,

John Price, CSP
