All this smoke proved how important it is to have gasmasks on hand. I was one of the only people I know that had gasmasks and 40mm NATO filter cartridges on hand. They made a huge difference for being able to work and be outside without risking my health. Everybody should have a proper gas mask for every member of their family. Fernez Sperian French Gasmasks are a great deal on eBay, as are the Israeli children's gasmasks. They both take 40MM Nato filters.
