The Following CURRENT CFR PART REQUIRES CHANGE!
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.

Divers allowed the ADC to take over the industry and their wallets by staying low, until every diver mans up and stands up, we will continue to make less than the burger boy at Mc Donalds. Most of these guys dont know what real money was like Dale, they will never understand what it means to stand for something, because they came into an industry after the Damage was already done!

Divers were held in high regard and paid top wages that is until J****** the frenchman brought SCUBA gear into the picture.

What ever Coueasteau, did, neither the Coast Guard, nor OSHA recognize it as a safe practice. If the ADC has its way, they have added Scuba to the agenda in the new CFR's they plan to submit. The Coast Guard already has a copy in their hands. And they are NOT happy with this, it is considered blatant deception, Its a reference based on references to weed out real divers, and replace us with rookies who are under their standard. If you look at the Membership BOARD, the Overseas reps on the board are there because Scuba is a normal cheap practice. they lose more divers than e do here every year - the reason, Three and sometimes two man dive teams operating on salvage and repair with NO COMMS! Thats why I started NAWD on Linkedin, the more members we can acc**ulate, the more votes we have against the ADC when their COPY of the CFR is presented. It can be shot down Immediately, and the floor will once again be open to DIvers to regain control. NAWD is NOT, I repeat NOT a Union, we are watch-dawgs, ready to use experience to stop stupidity when the COAST GUARD CFR is released for review. If you are commenting on the CFR on the Underwater Mag site STOP, it is NOT the Coast Guard Release, the ADC wants every one to comment on their copy and submit it to the USCG as the "INDUSTRY CONSENSUS" which means once again instead of us speaking for ourselves, they control the docket. Join us at NAWD - the National Association of Working Divers. Free, We are planning stickers, and Diver ID's with Ratings or something to denote the members ACTUAL Experience. Not just what an association agrees is our rating.

Submit this in a private e-mail to the coast guard in the subject line, Put I am seriously concerned, please respond. In the letter itself, list your reasons and concerns so that it will be put on the table for discussion.
Thanks Joseph

Ummm went looking for NAWD and found this instead http://www.nawd.com/
darn.
Can't get linkedin at work. Should also make is a gorup or something on FB or other places so it starts showing up on google searches. Otherwise Nat'l Ass. of Workshop Directors pops up..or National Association of Wh***sale Distributors.

Dale & All;
When we did the Devon Standard it was written so that if a diver passed the written Safety and the Practical Burning Test, Devon paid for it. All written questions were based on the Ocean Technology Oxy Arc Burning course. No one had to take the course. They just had to be able to test to its minimum standard.
Devon Burning Qualification
Personal Recommendations
All Personal ( Supervisor/s, Diver/s & Tender/s)
1.Written Safe Practices Test ( It was around 30 questions 10 of which were from their on dive manual.)
2.Demonstrate (practical): Set-up of equipment, Trouble Shoot Equipment, Maintenance of equipment, verbally explain the reasons for equipment selection to tester. (Welding Machine, O/2 Regulator, Burning Leads & type of rod).
3 Verbally explain Safe Venting Practices to tester
4.Divers: Demonstrate Safe Burning Technique with all Rods to be used on job.
