COMMERCIAL DIVING PERSONNEL

Requirement OSHA Regulation USCG Regulation Comments

Dive team members must be qualified to conduct assigned tasks.

29 CFR 1910.410

(a)

29 CFR 1910.120

46 CFR 197.404

46 CFR 197.410

There is not a “commercial diver certification card,” similar to those required by the recreational diving community. The Association of Diving Contractors International offers a certification card or the company can provide proof of experience. Divers should provide proof of HAZWOPER training before commencing diving operations in contaminated water.

All dive team members must have current CPR and first-aid certifications.

For surface-supplied and scuba operations, a qualified three-person dive team, consisting of a person-in-

(b)

46 CFR 197.432

The three-person dive team is an OSHA regulation and an accepted industry practice by the Association of Diving Contractors International. The mailto:Steven.E.Denner@uscg.mil mailto:Cody.R.White@uscg.mil charge, dive tender, and line-tended diver, is required.

Coast Guard requires a three-member dive team for Coast Guard contracts (ALDIST 228, 1999). The diving supervisor must not serve in a dual role as both supervisor and diver. A standby diver, when required, must be dressed out and ready to dive.

An experienced, designated person-in-charge is on-scene and supervising the operation.

(c)

46 CFR 197.208

46 CFR 197.210

46 CFR 197.402

46 CFR 197.404

Under the OSHA regulations, the person-in-charge is the qualified diving supervisor. When diving operations occur on an inspected vessel, under USCG regulations, the person-in-charge (the owner, agent, or master of the vessel) and the diving supervisor are separate individuals, and both must be designated in writing.

COMMERCIAL DIVING OPERATIONS

A Safe Practices Manual or Operations Manual must be available on-site.

Note: During salvage operations, welding and burning equipment should not be used to open tanks without first assessing contents and explosion risks associated with these types of operations.

46 CFR 197.420

OSHA regulations require a Safe Practices Manual that describes the diving activities, while USCG regulations require an Operations Manual that meets the requirements of the Safe Practices Manual. This is the site-safety plan. In particular, response personnel should review emergency procedures, emergency phone numbers, and the directions to the nearest decompression chamber and hospital. For contaminated water diving, a more specific safety plan that addresses the specific contaminant and protective equipment should be available.

The divers must have a plan to obtain emergency assistance, specifically, a two-way communications system.

29 CFR

1910.421(b)

46 CFR 197.420

46 CFR 197.314

(b)

If a decompression chamber is not required on site, ensure that the divers know the location and contact numbers of the nearest facility and hospital. Most importantly, the divers must have the capability to reach emergency services.

First-aid equipment, including a hand-held resuscitator, must be located on site.

29 CFR

1910.421(c)

29 CFR 1910.423

46 CFR 197.314

46 CFR 197.432

For dives deeper than 100-fsw (feet sea water) or dives outside the no-decompression limits, an operating decompression chamber and supply of breathing gas sufficient to treat for decompression sickness must be located on-site. The chamber must be within five minutes of the dive station.

The more conservative OSHA limitation of 100-ft depth should be applied.

SCUBA DIVING OPERATIONS

Scuba diving must be conducted in depths less than 130 fsw, within the no-decompression limits, and in currents less than one knot.

29 CFR 1910.424 (b)

46 CFR 197.430

(a) OSHA regulations require an operating decompression chamber on-site when diving greater than 100 fsw

SCUBA DIVING OPERATIONS

Requirement OSHA Regulation USCG Regulation Comments or outside the no-decompression limits.

Scuba diving is not appropriate where there is a risk of oil or toxic chemical ingestion. The NOAA Diving Manual states “Standard scuba gear offers inadequate protection to divers operating in contaminated water environments” (NOAA, 1991)

A standby diver is available while the scuba diver is in the water.

29 CFR 1910.424 (c)

(c) The scuba diver must be either line-tended or accompanied by another diver with continuous visual contact.

(d)

If the scuba diver must work in a physically confining space, another diver must line-tend the diver from the underwater point of entry.

(e)

During salvage operations and underwater oil recovery operations, divers must often penetrate the hull to conduct damage assessments, connect equipment, and recover floating oil.

Scuba divers must carry a reserve breathing gas supply.

COMMERCIAL DIVING EQUIPMENT

Air compressors used to supply air to the diver must be equipped with a volume tank with a check valve on the inlet side, a pressure gauge, a relief valve, and a drain valve.

29 CFR 1910.430

46 CFR 197.310

Air intakes for air compressors must be located away from areas containing exhaust fumes or other hazardous materials.

29 CFR 1910.420

46 CFR 197.310 (b)

The output of the air compressor systems must be tested for air purity every six months and after every repair or modification.

An analysis certificate stating the serial number of the compressor and the results of the air test should be available at the dive location.

29 CFR 1910.420

46 CFR 197.450

46 CFR 197.340

The diving supervisor must provide laboratory results or maintenance records for air quality. Compare the compressor identification number with that noted on the laboratory results or maintenance records. Compressed air used for breathing mixtures must be 20 to 22 percent oxygen by volume, have no objectionable odor, and have no more than 1000 ppm (particles per million) carbon dioxide, 20 ppm carbon monoxide, 5 mg/cubic meter of solid and liquid particulates including oil, and 25 ppm hydrocarbons.

PART 5 – Contractor Responsibilities:

1. Submit quotes within 5 business days.

2. Cut and remove all steel and concreate wreckages associated with all aids listed above. Contractor shall submit all pertinent information regarding completion of work to Petty Officer Steven Denner at Steven.E.Denner@uscg.mil or alternate Petty Officer Cody White at Cody.R.White@uscg.mil mailto:Steven.E.Denner@uscg.mil mailto:Cody.R.White@uscg.mil
