Introduction (repeated from scenario #1)
Diving is a pretty safe sport. Most divers are cautious and attentive in the way they prepare for and conduct themselves while diving. They know the rules and limits, they check their equipment over carefully, and they don't push the limits too far or too often. When it comes to injuries, we're probably more likely to get hurt playing softball or soccer than we are to suffer an injury on a dive. But when that unusual circumstance comes along, it's important to have a plan. After all, we can't stay underwater forever, and some problems need to be resolved pronto. We need to think about what could possibly go wrong on a dive, and have a plan for what to do if that "worst-case scenario" should arise.

With this in mind, we'll take a look [individually] at some of the most challenging situations a [recreational] diver can encounter. For each one, we define the scenario, identify the risk factors, examine the likely causes and suggest strategies for avoidance. Then we'll explore the various tactics to deal with the problem just in case it sneaks up on us.

Scenario: Accidental Weight Loss
You're roaming the reef, minding your own business, when you become buoyant.

Risk Factor:Most people welcome unexpected weight loss, but not when diving. Whether it's a loss of a weight belt, trim weight or individual weights from a pocket belt or integrated weight system, losing weight generally leads to an uncontrolled ascent, possibly of the rapid nature. This can lead to lung over-expansion injuries such as arterial gas embolism (AGE) and can contribute to decompression sickness.

Likely Causes: Loss of weights when diving can be the result of poor or neglected maintenance, mechanical failure or poor operating procedures.

Avoidance: A thorough inspection of your weight system prior to diving is the first step in avoiding accidental weight loss. Look for telltale signs such as worn Velcro fasteners and stitching, worn buckle teeth, and faulty release mechanisms. When using a conventional weight belt, make certain that the strap length is appropriate. There should be 4-6 inches of extra strap remaining when the buckle is secured. Less than that, and there may not be enough to grip to make underwater adjustments. Too much excess strap can lead to entanglements. During the dive, monitor your weight system, and adjust the belt tension as necessary.

Dealing with it: The first step in dealing with an accidental weight loss is to counter the effect by dumping air from your BC. If you're at the bottom and can find something to hang onto, it may be possible to retrieve and replace the lost weight and continue the dive. If an uncontrolled ascent begins, flare your body to maximize drag and slow your ascent, vent air from your BC and remember to exhale during the ascent.

You may also be able to put things in your pockets such as rocks etc to make you heavier to compensate for the lost weight.

(Fortunately for me the only time this happened I was in NC and found a firebrick that I could put in my wetsuit to compensation for the lost weight.)

Now THAT'S using your head in the middle of a crisis! Kudos on your quick thinking, WW.
