Section 312.16 Disposition versions

2015-12-31

312.16. Lifeline: Subject to section 312.19, a diver must be tethered to the surface by a lifeline.

The lifeline must

(1)  be made of cord

(a)  of material other than natural fibre or monofilament polypropylene;

(b)  at least 12 mm in diameter;

(c)  whose total minimum length is 15 m greater than the length used underwater;

(d)  with a breaking strength greater than 20 kN; and

(e)  free of knots and splices, except at the ends where only splices are allowed;

(2)  be secured, on the surface,

(a)  to an anchorage point that ensures a breaking strength greater than 20 kN, for surface-supply diving, unless that point is a boat that cannot ensure that strength, in which case the cord must be secured to an anchorage point as solid as possible; or

(b)  to an anchorage point that ensures a sufficient breaking strength when the lifeline is at its maximum tension, for scuba diving; and

(3)  be attached to a diving harness.

In addition, the lifeline must

(a)  allow to transmit line signals, pull a diver up or stop a diver’s movement underwater; and

(b)  protect the air hose and communication cable against tension when it is integrated into an umbilical.

The lifeline must

(1)  be made of cord

(a)  of material other than natural fibre or monofilament polypropylene;

(b)  at least 12 mm in diameter;

(c)  at least 1.5 times the length used underwater;

(d)  with a breaking strength greater than 20 kN; and

(e)  free of knots and splices, except at the ends where only splices are allowed;

(2)  be secured, on the surface,

(a)  to an anchorage point that ensures a breaking strength greater than 20 kN, for surface-supply diving, unless that point is a boat that cannot ensure that strength, in which case the cord must be secured to an anchorage point as solid as possible; or
