Before arriving back in LA, Makarskyy said, he prepared for his return by checking national alerts within GOES, such as high-wind advisories, air quality and the location of wildfires. Each alert came with access to content written by wilderness medicine doctors on preparation and mitigation techniques.
He read up on "what to do in breathing problem scenarios" related to those alerts. He said he learned that N95 masks are "the only thing that can protect against particulates that are that fine, that small."
"So rather than buying common surgical masks," Makarskyy said, "I went ahead and bought the right product for us to keep our lungs safe in this environment."
