OTS Recommended Setup of Diver ComRope |
|
|
It is extremely important that the divers are dressed out in a manner that will strain-relieve the ComRope. Commercial dive schools typically instruct students to have the ComRope tethered to the diver’s harness or buoyancy compensator with a quick release. If someone pulls on the ComRope and the diver loses control of the ComRope, the pull is on the harness, not on the diver’s mask. This setup prevents accidental removal of the diver’s mask. |
|
|
Strain-relieve the ComRope in two places on the diver’s end. The first point should have some sort of “D-ring” heavily taped or tied about 4 feet from the Hi-Use® connector (# 24). This “D-ring” will be clipped onto the diver’s harness or buoyancy compensator via a carabiner or some good quality quick-disconnector. This connection will help prevent the ComRope from pulling on the diver’s full-face mask. If the diver is set up properly, the tender’s pulling on the ComRope should pull on the diver’s hand loop first. If the diver is not holding the hand loop, the strain should go to the belt “D-ring,” not the diver’s full-face mask or diver’s earphone-microphone assembly (# 22 & 23). The diver should tie the ComRope, making a hand loop about 6 inches in diameter about 10 feet from the Hi-Use® connector. The diver will now be secured to his harness or buoyancy compensator and have a hand-hold he should hold during the dive. The diver should have control of the ComRope throughout the dive. He should feel what is going on, giving topside directions when slack needs to be taken up or when more rope needs to be paid out. If the diver lets go of the hand-hold, the carabiner–D-ring combination will absorb the tension. In the event the diver must break lose of the ComRope totally (i.e., in an emergency), the diver should let go of the ComRope hand-hold and unsnap the device holding the D-ring. The diver then should let topside know what is going on before he detaches the Hi-Use® connectors. The diver then should proceed directly to the surface and reestablish communications. |
|
| The tender should ensure the ComRope on his end is also strain-relieved in some manner. This will prevent the diver or topside tender from pulling on the connections made on the electronics module. | |
