Abstract:
1. A method relating to retrofitting at least one existing underwater dive system to enhance the safety of at least one diver operating in waters containing at least one hazardous material, such at least one existing underwater dive system comprising at least one existing dive helmet, at least one existing surface-supplied breathing-gas subsystem, at least one existing in-water exhaust subsystem, and at least one breathing environment available to the at least one diver, said method comprising the steps of: a) identifying the at least one existing underwater dive system comprising the at least one existing dive helmet, the at least one existing surface-supplied breathing-gas subsystem, and the at least one in-water exhaust subsystem; b) identifying, within the at least one existing underwater dive system, potential hazardous-material-caused failure points that result in at least one injurious introduction of at least one hazardous material into the at least one breathing environment during at least one operational duration; c) designing at least one risk-mitigating modification to such at least one existing underwater dive system, such at least one risk-mitigating modification being structured and arranged to substantially mitigate risks associated with such hazardous-material-caused failure points identified to occur within the at least one operational duration; d) providing at least one retrofit kit comprising materials and procedures required to implement such at least one risk-mitigating modification to such at least one existing underwater dive system; e) wherein the step of designing at least one risk-mitigating modification to such at least one existing underwater dive system further comprises the steps of f) wherein the step of designing at least one risk-mitigating modification further comprises the steps of g) wherein the surface-return exhaust subsystem comprises h) wherein the surface-return exhaust subsystem further comprises
