October Meeting:

Normal Meeting sequence is as follows:

  1. Introduce Visitors.

Last Meeting Highlights:

There were 18 members and one visitor (Steve) present at the last meeting, the meeting started with John N and Mac passing around some very nice recent river finds, Comments by Bob S and Jim S on the 12 wrecks dove during the Cheboygan, Mackinaw & Lake Huron & Superior dive trip. During the week, the max dive depth was 145 feet with the average dive being between 30 & 40 feet. Visibility varied with an average of 25 to 30 feet in Lake Superior (apparently due to particulate) and 85 to 90 feet in Lake Michigan & Huron, Videos to be available on U-tube and FB later, Discussion and comments on the upcoming Oct 1 Ecology Dive in Niles concerning start time, locations to dive, the need for wheel barrows and shore support. Sample posters for the event were passed around. Ron J and Deb W were the first to pay their dues for 2017 J. With the meeting ending a little early most went to Roma’s for pizza and continuing discussions.

 2016 Dive Listing:

 Organize a dive and paste it on the Facebook MUD club site.

Thirsty Thursdays:

Come on down and join the fun on “Thirsty Thursdays” beginning at 5:00 until 7:00 p.m. All divers greatly appreciate “everyone” who comes and provides support for the activity.  Dives can be labor intensive and “many hands make light work”.  The gathering afterward for food and diving discussions are just about as much fun as the dive itself. The las t two are scheduled for Oct 20 & Oct 27. Monitor the face book Mud Club site for updates on weekday and weekend diving. J

 Reminder:

When was the last time you invited a new diver (or old diver) to dive with you?

Divers Corner:    Do YOU use a pre-dive checklist?

Background

The effect of using a pre-dive checklist on the incidence of diving mishaps in recreational scuba diving was reviewed. Scuba diving mishaps, caused by equipment problems or human errors, increase the occurrence of injuries and fatalities while diving. Pre-dive checklists may mitigate mishaps. The following is the results of a study evaluating the effect of using a pre-dive checklist on reducing the incidence of diving mishaps in recreational divers.

Methods

A multi-location cluster-randomized trial with parallel groups and allocation concealment was conducted. The participants had to be at least 18 years of age, permitted to dive by the dive operator and planning to dive on the day of participation. They were recruited at the pier and dive boats at four locations. The intervention group received a pre-dive checklist and post-dive log. The control group received a post-dive log only. The outcomes, self-reported major and minor mishaps, were prompted by a post-dive questionnaire. Mishap rates per 100 dives were compared using Poisson regression with generalized estimating equations. Intent-to-treat, per-protocol and marginal structural model analyses were conducted.

Results:

A total of 1043 divers (intervention = 617; control = 426) made 2041 dives, on 70 location-days (intervention = 40; control = 30) at four locations. Compared with the control group, the incidence of major mishaps decreased in the intervention group by 36%, minor mishaps by 26% and all mishaps by 32%. On average, there was one fewer mishap in every 25 intervention dives.

Conclusions:

In this trial, pre-dive checklist use prevented mishaps which could lead to injuries and fatalities. Pre-dive checklists can increase diving safety and their use should be promoted.

 What is a pre-dive checklist?

The Buddy Pre-Dive Safety check is an important safety check that should be performed by every diver no matter what level of diving proficiency. This check is performed by a Scuba Diver with their buddy before descending on a dive as a final inspection of the dive equipment before diving. The Pre-Dive safety check ensures that your equipment is working and also familiarizes yourself with your buddie’s equipment should you need to assist or receive assistance from them. Most Scuba diving accidents and incidents are said to be preventable by the diver simply having properly conducted a pre-dive safety check. Despite the warnings, most divers seldom perform this crucial scuba gear check before a dive, and rush to descend. Especially if your scuba equipment has been set-up by someone else, a diver should always inspect his own gear and perform a buddy check before descent.

B BCD & Buoyancy: Check your buddies Buoyancy Compensator, check that the low pressure inflator hose is connected correctly and have them do a quick puff to ensure the inflator button doesn’t stick. Also have them deflate the BCD to ensure it deflates correctly. If you are performing the check in the water, also check your own buoyancy to ensure you are weighted correctly. Don’t forget to connect and verify your dry suit inflate hose is functioning and well as suit exhaust valve.

W – Weights/ Weight Belt: Check that your buddies weight belt has the loose end tied correctly and tucked in a manner that will allow for quick release and / or verify their integrated weight pouches are inserted properly and secure.  Make sure you are familiar with the type of weight belt or integrated weights being used by your dive buddy and you know how to release them should you need to.

R – Releases: Check that your buddies BCD is on correctly, belts and belly snaps fastened, shoulder straps straight and snugged down.

A – Air: Check that your buddy’s air is turned all the way on. Have them take a couple of breaths while you both watch the pressure gauge for fluctuations in the needle, or simply purge the regulator while watching the needle. Check that the tank is full and check all air connectors for leaks. If you are wearing an alternate air source verify its operation by taking a couple of breaths from it, ensuring that it is properly attached on the BCD and the regulator is easily accessible.

F – Final OK: Final check is a cursory visual inspection, hood, gloves, mask, snorkel, fins. Make sure you test your dive light if taking one along, take a compass bearing if using one, and turn on and verify your dive computer is functioning before giving the all Ok sign to your buddy to begin descent.

Feel free to use a mnemonic to help remember the pre-dive check “BWRAF. There are various mnemonics available so use one you’ll remember. Here’s a fun one:  Burgers With Relish And Fries

Remember:

Its October and the deeper depth waters are chilling out fast, for water temperatures below 50°F most divers will prefer dry suits for long time immersions. Double dipping requires a warm up interval and warm water for the wet suit to take out the chill.  Get wet now before the hard water really takes over. Or go DRY now J

Dive Safety Starts and Ends with YOU

Always remember, anyone can call off a dive at any time. In other words, it’s always OK to say “No”.
