Occupational Health and Safety Act, 1993 (Act No. 85 of 1993)

Where a diving operation is carried out at night, a lamp or other device must be attached to the diver to indicate his or her position when he or she is on the surface.

The surface area and the bell from which the diving is taking place and the underwater working area must be illuminated well. If such illumination is undesirable, it may be switched off during the diving operation, but be immediately available in the case of an emergency.
