Environmental protection workers stripped seaweed and barnacles Thursday from a tsunami-wrecked dock washed up on a U.S. beach, to guard against “invasive species” from Japan.
A dozen or so workers and volunteers used shovels, rakes and other tools to scrape the wreck clean, then briefly used low-pressure flame torches to sterilize the dock, said the Oregon Parks and Recreation Department (OPRD).
The wreck has been checked for radioactivity—the killer earthquake and tsunami triggered a disaster at the Fukushima nuclear plant on Japan’s east coast—but proved negative, said the OPRD spokesman.
“Because of that and the possibility of other species that don’t belong here, we’ve cleaned the entire surface of the dock. After they scraped it down, they hit it with a short burst of fire to sterilize it.”
