A substance is toxic if sufficient exposure can cause death. For example, 1000 parts per million (ppm) CO concentration will cause unconsciousness after 1 hour.

Yes - FireAde 2000 quickly attacks many poisonous and potentially fatal toxins that are frequently present in dense smoke upon contact with fire. Visibility is significantly increased. No - Dry Powder Chemicals do nothing to remove poisonous or toxic smoke from the fire. Dry Powder Chemicals alone are not safe to breath.

The tonicity of the solution is less than that of the cells. When this occurs, water enters into the blood cells causing them to swell and finally burst, with the liberation of hemoglobin, or water invasion of the body’s cells. If this invasion is beyond the body’s cells, then water intoxication results, with convulsions and edema.

The tonicity of the solution is greater than that of the cells, which can cause a variety of complications, such as, hyperglycemia, intracellular dehydration, loss of water and electrolytes, dehydration and coma.

Here a "hack" is a clever shortcut or a lesser-known, faster way to get something done. A hacker believes that information-sharing is a powerful positive good, and that it is a hacker's duty to share her expertise—so we will.
