How to contain enough arsenic dust to kill everyone on Earth
In short: After gold production ceased at Canada's Giant Mine, a massive environmental crisis was left behind. This video explores the high-stakes engineering solution used to stabilize a lethal amount of arsenic trioxide.
Following the bankruptcy of the mining company, the Canadian government inherited the responsibility of managing the waste at Giant Mine, located near Yellowknife in the Northwest Territories. The site contains roughly 200,000 tons of arsenic trioxide dust. To prevent a global catastrophe, engineers are currently using a freezing method to keep the toxic dust contained, providing a temporary solution to a massive environmental threat.
