Rule 9?
I had 6 running cave lights and 2 backups., 2 x 18 ltr. tanks at 220 bar at the start of the dive. A scooter and a pair of fins. Cookies, arrows, and 2 spools. Energy bars and cyalume lights inside the scooter. Plenty of redundancy (spare mask...).
For your other comments, there is other threads pertinent to those (but no I am not going to rediscuss O2 narcosis, rebreather functional safety, flying pigs, and the rest. No interest).
No bottom Timer, No depth gauge, No dive tables.... AND OBVIOUSLY No back up for these items either. Yea, you blew Rule 9.
NACD STANDARDS FOR CAVE DIVING - Equipment:
Minimum Equipment: Mask, fins, submersible pressure gauge, exposure suit suitable for diving location, BC with power inflator, slate and tables, knife, timing device, appropriate weight, three battery powered lights, 71.2 cu. ft. tank with manifold, primary reel with 400+ of guideline, safety reel, additional first stage with a minimum five foot hose, line markers, clothes pins and an additional light for a total of three, compass, primary light with minimum of 20 watts, two secondary reels and line arrows
IANTD Technical Cave Program Equipment Requirements:
All students will be taught the concept of gas matching. All bottom mix tanks will be equipped with dual outlet valves. If a Rebreather is used, it must be equipped with adequate bailout to make a safe ascent to the decompression stop(s). The total team bailout should enable the diver to reach the surface safely including staged or transported (via surface support divers) bailout gas
For OC two primary regulators, one of which must have a second stage hose of 1.5 metres (4.5 ft) in length longer hoses are recommended. This longer hose must be attached to one of the second stages to facilitate gas sharing
One or more separate stage tank(s) sufficient for decompression must be carried by the diver
All cylinders must be correctly labeled as to gas content according to IANTD standards
The oxygen or highest EANx regulator must have some form of guard or cover to prevent accidental use
All independent breathable gas sources must feature a submersible pressure gauge
A primary BCD and a backup BCD is required if a diver is using a wetsuit and is sufficiently negative in buoyancy that he/she cannot maintain floatation without the use of a BCD. If dry suits are used, the dry suit may be considered the emergency BCD floatation in lieu of a backup BCD. Lift bags and other buoyant sources may not be considered as redundant BCDs
When performing dives in OW: If during confined water training it is discovered that the student cannot remove his/her equipment in less than 1.5 minutes and/or if a buddy cannot, while having the student act as a victim in need of assistance, remove the students equipment in under 1.5 minutes, a quick-release mechanism on the harness will be required. IANTD recommends the use of a quick release located below the shoulder D-ring, as close to the base of the harness as possible
A lift bag of at least 22.5 kg (50 lb) lift capacity and a line reel for deployment
A backup cutting tool is recommended
Decompression tables and accurate depth gauge, plus bottom timer device or a dive computer is required
A backup dive computer or bottom timer/depth gauge is recommended
Tanks must be labeled with IANTD stickers or other identification, such as may be required by community practice or local laws and regulations. At a minimum, the labels must clearly identify the MOD and oxygen content of the mixture. It is recommended that IANTD labels be used to meet this requirement, in addition to those required by law
