| | Standard diving dress - Wikipedia, the free encyclopedia |
 | | A standard diving dress consists of a metallic (copper, brass or bronze) diving helmet, an airline or hose from a surface supplied diving air pump, a canvas diving suit and boots. |
 | | An important part of the equipment is the addition of lead weights, generally on the chest and boots, to counteract the buoyancy of the helmet and diving suit. |
 | | The watershed development in hardhat diving was the "closed" dress, in 1837 by Augustus Siebe, where the helmet was sealed to the suit making the suit watertight, the helmet could not flood no matter how the diver moved, resulting in safer and more efficient underwater work. |
