3. RESPONSIBLE POSITIONS

3.1 The following positions or groups have action item responsibilities within this procedure:

• Ship Commanding Offier

• Chief Marine Engineer

• Officer of the Deck

• Competent Person

• Marine Chemist

4. RESPONSIBILITIES AND PROCEDURES

4.1 Background

The high temperatures, molten metal, and sparks produced in hot work operations have been the cause of disastrous fires, both ashore and at sea.

4.2 Responsibilities

4.2.1 The Commanding Officer (CO) ensures all hot work operations are conducted per this procedure.

4.2.2 A Ship Specific Instruction (SSI) is required to list designated hotwork areas and qualified individuals.

4.2.3 The competent person prepares required permits and completes the hot work operation prerequisites.

4.2.4 The hot work operator conducts all hot work operations safely.

4.2.5 Fire watch personnel ensure fires do not start as a result of hot work operations, and in the event that a fire does start, fire watch personnel sound the fire alarm and begin extinguishing the fire.

4.3 Hot Work Procedures

4.3.1 Hot work operations conducted by ship’s force are only performed by a trained and qualified hot work operator as designated by the Chief Marine Engineer (CME) or Competent Person and approved by the CO. A list of the designated hot work operators is maintained aboard the ship (posted where other qualification lists are maintained). In addition to the hot work operator, all hot work operations must have at least one person on fire watch at the hot work location.

4.3.2 The hot work operator uses required personal protective equipment (PPE), as indicated in the OMAO Procedure 1701-06 – Personal Protective Equipment, including:

• Eye and face protection;

• Electrical safety gloves when removing or replacing electrodes;

Hot work must not be performed:

• During fueling or oil transfers;

• If it is likely to cause a fire or explosion;

• On surfaces that will emit toxic fumes when heated;

• In confined spaces without marine chemist

“Safe for Hot Work” certificate; or

• In spaces or adjacent spaces that contain concentrations of flammable vapors greater than

10 percent of the lower explosive limit (LEL), except in designated hot work spaces (see below).

Page 3 of 6 Procedure 1701-09

• Respiratory protection, type determined by task and location, see OMAO Procedure 1701-07 – Respiratory Protection Program; and

• Leather gloves, aprons, and jackets as appropriate.

4.3.3 Hot work operations may only be conducted if all fire systems are as fully operational as possible and a fire watch is assigned. During periods when fire system components are disabled due to repair or removed from the ship, an equally effective means of fire detection or suppression must be used.

4.3.4 Hot work operations in confined spaces may only be performed if:

• The ship is in port;

• Safe for Hot Work Certificate is issued by Marine Chemist;

• All Confined Space Entry requirements indicated in OMAO Procedure 1701-10 – Confined Space

Entry Program are met; and

• Gas cylinders, manifolds, and other cutting equipment remain outside of the confined space.

4.3.5 During welding operations:

• When practical, shielding should be provided and/or restrict access to protect others from viewing the arc;

• Gas supplies must be secured at the cylinder or manifold when equipment will not be used for periods greater than 30 minutes or will be left unattended for periods greater than 15 minutes;

and

• Torches and electrodes must be disconnected from the hoses/supply cables when not in use for periods greater than 30 minutes or left unattended for periods greater than 15 minutes.

4.3.6 Designated Hot Work Areas:

• Whenever possible, a space such as a workshop should be designated for hot work to be performed and should be the first place considered for performing hot work operations.

• Designated hot work areas must be prepared and maintained per section 4.4.1 of this instruction.

• The precautions section of NOAA Form (NF) 57-17-09 - Hot Work Permit must be completed by the CME or their designee (no signatures necessary). The EOW shall serve as the CME designee for completion of the precautions required by this section for hot work conducted in the designated hot work area.

• The OOD is notified when hot work will be performed and when completed within a designated area.

• Any hot work performed on a bulkhead within a designated area will still require the completion of a hot work permit.

• A list of the designated hot work areas must be maintained in the SSI. The Thomas Jefferson maintains the Machine Shop, space 2-75-0, as the only designated hot work area.

4.4 Hot Work Prerequisites

4.4.1 Before hot work operations may commence, the following preparations of the hot work area must be completed:

• The subject space and adjacent spaces are inspected to determine potential fire hazards;

• Combustible materials inside the subject space, within 35 feet of the hot work area, are moved to another space, covered with a fire proof cloth, or shielded with a metal guard;

• Combustible materials inside adjacent spaces are removed from the opposite side of the subject space bulkhead, overhead, or deck below.

• Machinery and equipment that cannot be moved in the subject space is covered by a fire proof cloth, or shielded with a metal guard;

• The edges of the fire proof cloth are tightened or secured so to provide significant overlap and protection to keep sparks from getting under the cloth.

• Lockout / tagout requirements in OMAO Procedure 1701-05 – Lockout/Tagout are complied with, if applicable;]

• Ducts that could carry sparks are blanked off;

Page 4 of 6 Procedure 1701-09

• Sufficient ventilation (fixed or portable) is provided to remove smoke and keep flammable vapor concentrations within safe limits.

4.4.2 Before hot work operations may commence outside of a designated hot work area, the following administrative requirements must be in place:

• The CME/Competent Person certifies the area or space “Safe for Hot Work”;

• The CO or designated representative approves the hot work and document approval in the ship’s deck log;

• A Hot Work Permit (NF 57-17-09) is completed, including precautions and all signatures (ship specific requirements can be added to the permit).

o Onboard Thomas Jefferson, the Competent Person will route the Hot Work

Permit for signature through (in order):

1. Chief Marine Engineer

2. Commanding Officer

3. Officer of the Deck o Original copies of the signed form will be posted in the workspace.

o A scanned copy of the signed form is to be archived in the <N:\Public\Digital

Binders\Hot Work Operations\Chits> folder on the ship’s network \\OMAO-

TJ-FS2.

• The NF 57-17-09 is posted in the adjacent space on the bulkhead next to the entrance of the hot work space.

4.4.3 Before hot work operations may commence, the following support personnel must be in place or notified:

• A trained and competent fire watch, per section 4.4.5 of this procedure, is posted in each space where a fire may occur as a result of the hot work operations;

• Radio communications is established between each member of the fire watch, the hot work operator and the Officer of the Deck (OOD);

• The OOD makes an announcement on the ship’s public address system notifying all shipboard personnel of the ensuing hot work operations; and

• The fire watch notifies the OOD when hot work commences.

4.4.4 A certified Marine Chemist must issue a “Safe for Hot Work” certificate before hot work operations are conducted in any of the following locations:

• Within a confined space;

• Within or on the boundaries of tanks that have been used to carry combustible liquid chemicals or petroleum products;

• Upon any pipeline, heating coil, pump, fitting, or other appurtenance connected to such tanks.

Additionally, for contractors working aboard:

• Within any space adjacent to tanks that have been used to carry liquid chemicals or petroleum products, unless distance between such tank and hot work is greater than 25 feet.

4.4.5 A fire watch is required in each space where sparks or heat transfer may ignite combustibles.

Multiple fire watch personnel may be required. The fire watch:

• Has the authority to stop any hot work operation, for any reason;

• Has no other assigned duties while maintaining a fire watch;

• Reviews all posted permits and certificates;

• Is knowledgeable in sounding the fire alarm;

• Is properly trained in the use of firefighting equipment;

• Is equipped with appropriate firefighting equipment;

• Is equipped with appropriate PPE, as required for the operation; and

• Is maintained without interruption, including meals and other breaks.
