PortaCount Testing Day

We have another PortaCount testing event, this time in Castle Rock! This is a high-quality quantitative fit-testing machine for masks.

KN95 or better mask required; we can provide a KN95 or N95. Rain will cancel. This is an all ages event.

Special information to know for the PortaCount testing:

1. Testing Honeywell, Moldex, GVS, Trend, Flo Mask and 3M bayonet-style reusable respirators with adapters will not damage the mask.

2. Any disposable mask can be tested, but the test probe puts a hole in the mask, so you won’t be able to reuse it. Make sure to bring a backup mask to wear or have a SIP valve installed prior to testing.

3. Bring a mask that appears to fit you well.

4. These tests take a minimum of 6 minutes per person, and more likely 12. Plan to be waiting to be tested.

5. Testing masks modified to fix gaps such as with chin staples is fine.

6. Those with facial hair need to shave in the area where their mask seals.

What is a PortaCount?

From the manufacturer’s website: “The TSI PortaCount is the most widely used and trusted Quantitative Fit Test method. The PortaCount provides a direct assessment of respirator fit by comparing the concentration of ambient dust particles outside the facepiece to the concentration of particles that have leaked into the facepiece.”

Best practices for our in-person events:

• If you’re feeling ill, don’t come.
• Take 3 rapid tests, each 48 hours apart, before the day, and mask indoors for the 5 days prior to the event (we hope you already mask everywhere).

Disclaimer: rapid testing does not guarantee that there is no risk, but testing and two-way masking mitigates a lot of risk.

Other details:

• Bring chairs/blankets and any games you want to play while waiting (and come hang out even if you aren’t getting fit tested)!
• There are portapotties available, as well as restrooms elsewhere in the park.
• There is no public transit access to this location.

Rain will pause or cancel the event.
