Aluminum - Standard Consumables

EXPLOSION HAZARD – CUTTING WITH ALUMINUM NEAR WATER. Do not cut aluminum alloys underwater or on a water table UNLESS you can prevent the accumulation of hydrogen gas. Never cut aluminum-lithium alloys in the presence of water. Aluminum can react with water to produce hydrogen, resulting in a potentially explosive condition that can detonate during plasma cutting operations. Refer to the Safety and Compliance Manual (80669C) for more information.
