Minimum ignition energies

In this, the final part of a two-part report, the authors take a look at the electrical energy required to ignite certain solids in air and in oxygen both at 1 atmosphere and at hyperbaric pressures. Increased use of oxygen-enriched atmospheres in medicine, undersea exploration, and the space program (twice with tragic results) has caused attention to be focused on the effects of oxygen enrichment on the flammability of materials.
