|The Kirby Morgan® Commercial Diving Helmet 57 continues the tradition of innovation by providing the highest quality and superior performance that commercial divers have come to expect in a Kirby Morgan product. This helmet features Kirby Morgan’s revolutionary new Kirby Morgan SuperFlow 450™ Stainless Balanced Regulator which is machined from a stainless steel casting for the ultimate in performance and reliability. This commercially rated regulator delivers all the breathing gas commercial divers need for the most demanding underwater work.
The Kirby Morgan® Commercial Diving Helmet 57 also includes the Quad-Valve™ Exhaust System. It’s recommended for commercial diving in biologically contaminated water, when you’re properly trained and equipped, using recommended procedures. This new exhaust has exceptionally low exhalation resistance that you must experience to appreciate. Don’t confuse the Kirby Morgan SuperFlow® 450 with a sport diving regulator – it’s designed from the ground up strictly for commercial diving. With a rugged extra long adjustment knob and shaft, the Kirby Morgan SuperFlow® 450 meets the wide range of breathing gas pressures provided by typical low pressure surface-supplied diving compressors. Dive the Kirby Morgan® Commercial Diving Helmet 57 once and commercial divers won’t want to dive with anything else.
Warning: Before attempting any diving in any type of contaminated water, a complete commercial diving and topside course in hazardous materials emergencies should be completed. The commercial divers and the topside team must be properly trained and have the proper safety equipment. All commercial divinghelmets and suits can leak water under certain conditions. Commercial divers should use extreme caution when diving in contaminated waters.
|The Kirby Morgan® Commercial Diving Helmet 57 has been tested and conforms to the performance requirements as set forth in Annex II of Directive 89/686/EEC and, as far as applicable, the EN 250:2000, EN 250/A1:2006 and EN 15333-1:2008 (class B). It is fully CE marked with demand regulator SuperFlow® 350 and oral nasals P/N 510-690 and P/N 510-747.
The Kirby Morgan Hot Water Shroud (Part #525-100) in conjunction with hot water to the commercial diver should be used whenever commercial diving operations are conducted using HEO2 at water temperatures less than 60°F (15.56°C) for the comfort of the commercial diver. Kirby Morgan DSI further recommends that the hot water shroud be used in conjunction with hot water to the commercial diver whenever commercial diving operations are conducted using air or mixed gas, in waters colder than 36°F (2.22°C) to reduce the possibility of demand regulator icing.
Usually the greatest danger of demand regulator icing will be encountered on deck when the surrounding air temperature is less than 32°F (0°C). This effect is primarily due to the refrigeration effect of breathing air pressure reduction, and the addition of moisture from the divers exhalation coming in contact with the topside air temperature.
If diving where the water temperature is 36°F (2.22°C) or warmer but the topside air temperature is below freezing, (32°F (0°C) icing of the demand regulator is possible. To help eliminate the possibility of freezing on the surface, warm water should be run over the exterior of the demand regulator prior to water entry, if the hot water system is not used.
Only commercial diving equipment certified and tested according to EN 250/E DIN 58 642 may be used with the The Kirby Morgan® Commercial Diving Helmet 57 when conducting commercial diving operations in European EC compliant countries.
The umbilical assembly should be composed of good quality diving hose that meets industry standards. Generally, gas hose will be married to the communications wire, pneumofathometer hose, and strength member in a manner that will allow the strength member to receive all the strain. There are also good quality umbilicals available that are assembled at the factory using a twisted method which does not require marrying. Regardless of the system used, the umbilical is the commercial diver’s life line and should always be of excellent quality and maintained carefully.
