The Following CURRENT CFR PART REQUIRES CHANGE!
5. 29 CFR 1910.422(g) Welding and burning.
a. A current supply switch must be available to interrupt the current flow to the
welding or burning electrode. The switch shall be tended by a dive-team member in voice communication with the diver performing the welding or burning (see 29 CFR 1910.422(g)(1)(i)). The disconnect switch must be in the open position unless the diver is actually welding or burning (see 29 CFR 1910.422(g)(1)(ii)). The CSHO shall determine that the welding machine's frame is properly grounded and that cables, electrode holders and connections are insulated to prevent overheating or breakdown (see 29 CFR 1910.422(g)(2) and (g)(3)). The employer must provide insulated gloves for the diver's protection (see 29 CFR 1910.422(g)(4)).
NOTE: Personnel designated to operate electric cutting and welding equipment used in diving operations shall have experience or training in the safe use of this equipment (see 29 CFR 1910.410(a)(2)(i); welding and burning training violations will be cited under 29 CFR 1910.410).
b. This standard does not place any restriction on the use of AC current or rectified AC current arc welding.
c. 29 CFR 1910.422(g)(5). "Closed compartments" as used in this paragraph, means any space that is enclosed by bulkheads and overheads (i.e., walls and ceilings), including large diameter pipes and other structures that, because of poor ventilation, could hold or contain a flammable gas or vapor. Prior to hot work, the employer must remove from closed compartments all flammable gases and vapors by ventilating, flooding, or purging with an inert-gas that will not support combustion. Venting alone is not sufficient unless it removes the flammable gases from the compartments. Closed compartments, structures, and pipes already under flow, as in hot tapping operations, meet the requirement for being flooded.
WARNING: A flooded compartment is not necessarily safe for cutting and welding. During the cutting and welding process, oxygen, hydrogen (electrolysis), and other gases may collect in a closed compartment, if it is not properly vented (made gas free). Should the diver cut or weld into the area where the gas collects, then a serious explosion can occur. By properly venting the space, gas will not collect and the space will remain flooded.

Here is what I recommended to the ADCI all bassed on the only Burning Course I know of. Oceans Technology Inc Training Course. You will note the way it is written no one has to take the course. They do have to pass the testing required. have to pass the test.
Proposed ADCI OXY-ARC & Exothermic Underwater Burning Standard
Purpose
To establish proper safety precautions to be taken in order to prevent electrical shock, fire, and/or explosions while performing underwater burning operations. Underwater burning tasks should be challenged by exploring alternative cutting methods in lieu of oxy-arc/exothermic cutting processes.
Definitions
Oxygen/Arc Cutting Process: A method of underwater cutting through the rapid oxidation of metals. Heat is applied by an electric arc between the base metal and the tip of the cutting electrode. The electrode is placed at the line of cut and the metal is very quickly heated to a high temperature. Tubular steel electrodes are used. A high velocity jet of oxygen is directed through the tube to the heated spot and the melting operation proceeds. (The rod must be kept Hot)
Exothermic Cutting Process: This process operates similar to the oxygen/arc process and can be used in the same manner where rapid oxidation of metals is the primary cutting means. An electric arc between the electrode and the work piece melts a portion of the work piece. At the same time a jet of oxygen is forced down the hollow center of the electrode. Cutting is carried out by an exothermic reaction between the work piece and the oxygen jet. (The rod may be made Cold after initial ignition)
Pre-job Requirements
A. All personnel directly involved in Underwater Burning Operation, both the Oxygen/Arc Cutting Process and the Exothermic Cutting Process, shall have passed a basic Underwater Burning and Safety Class. (This should lead to licensing of Divers and Supervisors) The class and testing shall meet or exceed Oceans Technology: Oxy-Arc Underwater Burning Class.
B. Any oxy-arc/exothermic cutting operation is potentially hazardous and should, therefore, be part of a risk a****sment. The operational requirements in conjunction with the competency of personnel assigned to perform the task and the operational characteristics of the equipment should be a****sed to determine the degree of risk involved.
Minimum Requirements for Qualification.
1) Take written examination on all aspects of underwater burning, safety and practical. (All personnel in dive team). To be administered by third party.
2) Demonstrate set up and trouble shooting of Equipment. (All personnel in dive team) To be administered by third party.
3) All Divers that will burn underwater will demonstrate Safe Burning Technique with each Rods to be used on the job. (Observed by third party personnel)
Exothermic rod
A) Burn 6” Schedule 80 pipe using no more then 3 rods,
No Hangers. 4 minutes start to finish.
B) Burn 1” clean steel for a distance of 18” using no more then 5 rods,
No Hangers. 12 minutes start to finish.
C) Burn 2” clean steel for a distance of 18” using no more then 9 rods,
No Hangers. 15 minutes start to finish.
Tubular Steel
A) Burn ½” clean steel for a distance of 18” using no more then 3 rods,
No Hangers. 4 minutes start to finish.
B) Burn 1” clean steel for a distance of 18” using no more then 3 rods.
No Hangers. 6 minutes start to finish.
C) Burn 2” clean steel for a distance of 18” using no more then 5 rods.
No Hangers. 10 minutes start to finish.

John,
I agree with your recomendations with the exeption of it being time based That is just going to get people to rush Id rather a diver to take his time do it right and safe the first time than turning it into a compition and rushing the guy leaving room for mistakes

John isnt this the burning course with ocean technology that was invented by you about 13 or so years ago that I purchased on video?
Safety is a great thing thats how and why you and I are still here but I got to tell you I for one am sure getting tired of all of these so called new required certifications that keep popping up.
Who is going to administer this course ?
Is this just for the ADC ? or just those ADC companies ?
Who is going to pay for it ?
How often will it be held and is it open is it to everyone ???
This is beginning to look like bureratic BS piled higher and deeper from what I can see just my opinion.

All of this needs to be sent to the Coast Guard exactly as written by the Gentlemen who made each statement. Excellent points that need to be read by the reg writers...

Ace this is for the schools to strive for in there burning course.
If you teach burning this should be the minimum standard to strive for a student to pass the burning instruction.
the tuition for school pays for it.the way I see it.

Fred I understand however I am wondering how do the other divers who are now in the field become a part of this ??? who pays for it ? where will it be available ? How often is it going to be offered ? How often is it required ? will it have a shelf life ? Is this just another method for the big boys to control all u/w burning ??? Many questions to be answered here dont ya think ?

Ace, As you know the top burner gets the work and a guy that can not strick an arc sits home and gets to watch the big movie.
I cannot tell you the amount of money that was wasted on burning rod etc.because of so called divers that said they could burn, I know I spent a hell of a lot for non production and fired the wanna bee's.
If your a top hand diver its up to you to keep your skills fresh, Remember your reputation is only as good as your success on your last job.
Raise the bar and the quality of work and diver will raise also.
I learned how to burn , cutting ships in half before most of you were born, but I still jump in once in a while and burn a box of rod to improve.
Quit moaning about what it costs, its all tax deductable so its free.

Fred I wont quit talking about who pays for all of these certs as they are getting to be too much for divers to have to come up with. I for one am getting tired of spending my money for the certs that employers keep inventing.
Tax deductable WELL THAN EMPLOYERS SHOULD NOT HAVE ANY PROBLEM PAYING FOR THEM AND KEEP THEIR HANDS OUT OF THE DIVERS POCKETS BESIDES THEY WILL SAVE IN IN BURNING ROD COSTS AND ITS THEN THEIR TAX DEDUCTION.. My God after all we are really just labors who work and risk our all underwater.
No one to date taken the time to explain my orginal questions of;
Who pays for it?
Where and when cla**** will commence?
Will there be a expiration date on the training?
Will it be for everyone or just a select few big boy companies?
and just for the record I do believe in safety and upgrading my skills thats why I bought Johns course from Underwater Technology 13 yrs ago. .
Now with all of that said lets talk about upgrading divers wages-what say ?
Thanks for your responce Fred. I too love being a diver.

Exactly!!!!! Students have a bunch of down time, schools however limit the number of rods a kid can burn ( expence is the excuse) with most running 10-12 heads per class (or more), one can of rods per student minimum should be a good start.
-
-
THe guys who are already in the field, need to just keep practicing. THe Schools,though need to vamp up training in All hands on areas. Especially burning.

Ironcally, when I went to school, we did have a rod and time limit. I thought they were just trying to save money. Save money on the rods and save money by not extending the class time given the number of students.
It was a fun class, good test.
Both burning and welding
