Contractor Requirements

• Safe Practices Manual • Dive Operations Plan • AHA to cover all aspects job • Emergency Management Plan • Dive Personnel Qualifications

– Above requirements w ill be reviewed and accepted by two of the follow ing:

– DDC – ADC – DSR

Pre-Dive Conference

• Prior to initial work on each dive operations, a Pre-Dive Conference shall be held with key personnel designated by the DDC .

Diving Operations

• Staging area selected based on: • Ease of diver access to water • Hazards to diver in route from surface to

work area • Ability of standby diver to immediately

access water and quickly reach diver • If used, ability to protect top side members

from weather, operational and other hazards

Standby Diver

• A standby diver will be provided whenever a diver is in the water to serve as immediate emergency assistant to the primary diver.

• Shall be fully equipped to dive and readily available while primary diver is in water.

SCUBA Operations • SCUBA diving operations

shall not be conducted: • Depths > 100 ft (30.5m) • Dives outside the no-

decompression limits • Against currents exceeding

one knot • Enclosed or physically

confined spaces • Using closed/semi-closed

circuit SCUBA • Visibility < 3ft • Areas with pressure

differential • When diver don’t have

direct access to surface

Buoyancy Compensation Device (BCD)

Each diver shall be equipped with a BCD capable of maintaining the diver at the surface in a face-up position.

Weight Belts

• Each SCUBA diver shall be equipped with a weight belt or assemble capable of quick release.

Depth Gauge/Knife

• Each SCUBA diver shall be equipped with a depth gauge and knife.

SCUBA Tank Testing

• SCUBA tanks used on government projects must be visually inspected internally at least annually and hydrostatically tested at least once every 5 years.

Surface Supplied Air (SSA) Operations

Primary Breathing Gas

• Each diving operation shall have a primary breathing gas supply sufficient to support divers for the duration of the planned dive, including decompression.

Reserve Breathing Gas Supply

Reserve breathing gas supply

• An in-water stage shall be provided for divers without access to a bell for dives deeper than 100 ft (30.4m) or outside the no-compression limits.

Diving Compressors

• Air compressor systems used on-site as a direct source to SSA divers shall be equipped with a volume tank with a check valve on the inlet side, a pressure gauge, a relief valve and a drain valve.

Breathing Supply Hoses

• Hoses shall be suitable for breathing gas service or shall be specifically manufactured for SSA use.-

Scientific Snorkeling

• Scientific snorkeling will be allowed only for environmental assessments such as fish surveys, stream surveys,, and the like. It will not be used for structural inspection.
