The Iron lung was essentially a pressure chamber in which the the pressure could be increased quite a lot over atmospheric pressure as a means of forcing the absorbed coal gas back out. Its other common use was in treating polio, and also divers with the 'bends'. +++ Coal-gas is poisonous by being chiefly Carbon Monoxide, which is fast acting as it binds much more readily than the intended oxygen to the blood's haemoglobin. --- Also, the "iron lung" formerly used to treat polio, is a very different device from the hyperbaric or recompression chamber used to treat the "bends". The iron-lung is a an artificial respirator, the recompression chamber is not. Instead, it is a vessel large enough to accommodate the casualty, and filled with air at the pressure of the dive, then released very slowly.

Ancient Egyptians did not make iron tools for the first time; they primarily used copper and bronze tools during the early periods of their civilization. Ironworking became more common in Egypt during the Iron Age, around the 1st millennium BCE, but the knowledge of iron metallurgy was likely introduced from other regions, such as the Near East. While they did eventually produce iron tools, they were not the pioneers of iron production.
