Safety rules
Cave diving safety protocols should follow the Rule of Threes. The Cave Diver should have three sources for light and at minimum two tanks. They should also separate their gas into three distinct sections in order to have enough to last the dive. If the dive crew is experienced and has been diving in caves in the past, a more conservative gas management program is preferred. Cave divers must practice safe diving practices in order to avoid hazards from caves.
Equipment
Cave diving requires specific equipment. Two safety reels should be carried. One safety reel should be used to run the guideline while the other should maintain the line tension in the cave. When preparing for a cavern dive, make sure that each diver has a safety reel with sufficient line to reach the cave's entrance and the farthest permanent line. Manufacturers will often pack the reels up to the edge with guideline when making a new reel. This makes them more susceptible to jamming. To avoid a jam, you should cut off about 10 meters (30 ft) of line before use to reduce the risk of entanglement.
