Sections

30-4. Roles and Responsibilities.

Contract Dive Operations

Must adhere to the roles and responsibilities defined in the ADCI International Consensus Standards for Commercial Diving and Underwater Operations and the stipulations of the relevant chapter.

USACE Dive Operations

Must follow the roles and responsibilities specified in ER 385-1-86 and the relevant chapter.

Dive Supervisor (DS) Duties

Coordinate with controlling authorities to minimize hazards from various operations, establish safety zones with the USCG if needed, and develop site-specific plans as per paragraph 30-7.
Ensure pre-dive checks are conducted in line with paragraph 30-5 and develop Hazardous Energy Control (HEC) procedures to shield the dive team from diverse forms of hazardous energy, reviewing existing HEC procedures at facilities and ensuring the implementation of Lockout/Tagout (LOTO) and other control procedures.
Review procedures for operations involving Lifting and Handling Equipment (LHE), ensure communication with LHE operators, oversee the submission of Critical Lift Plans for diver access via LHE manbaskets, and ensure safety measures against electrocution during welding or cutting and against unplanned incidents during blasting operations.

30-4. Roles and Responsibilities.

a.  Contract dive operations will follow the roles and responsibilities outlined in ADCI International Consensus Standards for Commercial Diving and Underwater Operations and this chapter.  (30-4.a)

b.  USACE dive operations will follow the roles and responsibilities outlined in ER 385-1-86 and this chapter.  (30-4.b)

c.  Dive Supervisor (DS).  (30-4.c)

(1)  Coordinate with the controlling authorities to minimize the hazards associated with water traffic, land-based traffic, industrial operations, heavy equipment operation, or other operations that present a hazard to the diver or dive team (see para 30-8.a(7)).

(2)  Coordinate with the USCG to determine if there is a requirement to establish a safety zone.

(3)  Develop site specific plans and procedures according to paragraph 30-7.

(4)  Assure pre-dive checks are performed according to paragraph 30-5.

(5)  Develop HEC procedures to protect dive teams from hazardous energy including but not limited to mechanical (for example, power transmission apparatus, counterbalances, springs, pressure, gravity), pneumatic, hydraulic, electrical, chemical, nuclear, and thermal energies (for example, high or low temperature).  See chapter 12 and for pressure differentials see paragraph 30-7.

(a)  When diving at a facility with an existing HEC procedure, the DS must review the facility’s procedures and establish positive control procedures with the facility operator.

(b)  If HEC procedures are required for the diving operation, the DS must visually check all LOTO and other control procedures and devices to ensure they are in place according to accepted procedure.

(6)  For work involving LHE, review LHE signals and confirm radio communication with the LHE operator is functioning properly (see para 30-8.a(23)).

(7)  When LHE manbaskets are used for diver access, ensure Critical Lift Plan are submitted according to chapter 16.

(8)  Review welding or cutting procedures, select the proper welder polarity, and take precautions to ensure that electrocution will not occur (see para 30-8.a(24)).

(9)  Review blasting procedures and take precautions to ensure unplanned or unscheduled blasts will not occur.  See chapter 29 for additional blasting requirements.

(10)  Conduct a pre-dive and post-dive briefing according to paragraph 30-8.a.
