The requirements and procedures set forth in OSHA Standard, Title 29, CFR Section 1915, Occupational Safety and Health Standards for Shipyard Employment, and OSHA Standard, Title 29, CFR Section

1915.7 have been determined to be applicable to DESC vessel inspections, and shall be applied unless infeasible or impractical.

4.1.2.2. Where such situations or conditions may exist, alternative safety provisions shall apply to ensure the safety of DESC civilian and military personnel for the duration of their entry.

Those special provisions may particularly apply to operations outside the Continental United States (OCONUS), and further described under subparagraph 4.1.5. of this document.

4.1.2.3. DESC Quality Assurance Representatives, Quality Assurance Specialists and Quality Managers (QARs/QASs/QMs), hereafter referred to as 1910-series personnel, shall comply with Section 5.1.1.4. of MIL-STD 3004A, Quality Assurance and Surveillance for Fuels, Lubricants, and Related Products, Tanker Inspection Policy for MSC Vessels.

4.1.3. Marine Confined Space Entry Procedures - All Cargos

4.1.3.1. Prior to entry into any marine vessel confined space, the atmosphere must be tested for oxygen, flammable gas, and toxic contaminants by an authorized person (Marine Chemist, Certified Industrial Hygienist (CIH), or a Competent Person.

4.1.3.2. Testing of marine vessel confined spaces that last carried jet or diesel fuel may be performed by a qualified Competent Person. In the event the Competent Person encounters an unknown or unfamiliar toxin, or if ventilation cannot reduce the toxic levels to acceptable concentrations, OSHA advises the Competent Person to contact a Marine Chemist or CIH for assistance.

4.1.3.3. Entry into cargo tanks and adjacent spaces shall only be permitted after testing reveals that the atmosphere in the tank and all adjacent spaces is between 20.7–20.9% (20.8% is optimal), and 0% of the lower explosive limit (LEL).

4.1.3.4. Any test results that are not acceptable for unrestricted tank entry as noted in subparagraph 4.1.3.5., shall be investigated further, and if possible, ventilated to acceptable levels.

4.1.3.5. Acceptable test results for unrestricted tank entry:

4.1.3.5.1. Oxygen: 20.7-20.9% by volume (20.8% is optimal);

4.1.3.5.2. Flammable Gas: 0% LEL;

4.1.3.5.3. Carbon Monoxide: less than or equal to 25 ppm (parts per million) TWA (Time Weighted Average);

4.1.3.5.4. Hydrogen Sulfide: less than or equal to 5 ppm TWA;

4.1.3.5.5. Photo-Ionization Detector (PID) for Jet Fuels: less than or equal to 30 ppm TWA;

4.1.3.5.6. PID for Diesel Fuel: less than or equal to 15 ppm TWA.

4.1.3.6. Entry into tanks or spaces with acceptable test results may be performed without respiratory protection. Entry into tanks containing 1% to 5% LEL shall be performed with the use of half-face organic vapor cartridge respirators, provided this level of protection is sufficient for the contaminant.

4.1.3.7. 1910-series personnel shall monitor all fuel tanks to be entered with a calibrated multi-gas atmospheric testing instrument monitor. In spaces that have been previously loaded with fuels, concentrations of fuel vapors shall remain below 30 ppm for jet fuel and 15 ppm for diesel fuel. If the level is exceeded, either ventilate to restore acceptable conditions or respiratory protection is required.

4.1.3.8. Adjacent spaces are defined as those spaces in all directions from the subject space, including all points of contact, corners, diagonals, decks, tank tops and bulkheads.

4.1.3.9. Testing shall be performed in accordance with the procedures and techniques set forth in subparagraph 4.1.4.7 of this document.

4.1.3.10. Cargo compartment inspection delays due to high levels of flammable or toxic vapors or oxygen deficiency will be reported as a vessel delay.

4.1.3.11. All cargo system valves must be open, lines drained and secured prior to entry.

4.1.3.12. The multi-gas, atmospheric testing instrument shall be worn throughout entry and tank inspection (calibration of the instrument must meet the manufactures recommendation). If the oxygen, combustible gas, carbon monoxide, or hydrogen sulfide alarm activates, the 1910-series personnel shall exit the tank immediately.

4.1.3.13. An attendant must be present on deck at the top of the tank at all times during the tank entry and inspection procedure, to maintain constant communication with the individual who is in the tank. A member of the ship’s crew may serve in this capacity.

4.1.3.14. Emergency rescue equipment such as self-contained breathing apparatus, retrieval lines and communication equipment or other means of summoning help must be available in the event the entrant is injured or incapacitated.

4.1.3.15. A Marine Chemist or CIH might prescribe special conditions or instructions for entry, such as the wearing of an organic vapor respirator or the requirement for constant mechanical ventilation for the duration of entry. If so, the instructions shall be strictly adhered to in order for entry to proceed. Work authorized by the Marine Chemist Certificate must begin within 24 hours unless otherwise noted. Verify tank conditions as often as necessary in order to maintain a safe atmosphere.

4.1.3.16. 1910-series personnel who are required to wear respiratory protection shall comply with the provisions of the DESC-S-D-08-06, DESC Respiratory Protection Program Standard Operating Procedure.

4.1.4. Marine Vessel Confined Space Entry Procedures - Non-Toxic Cargos

4.1.4.1. DESC personnel trained and designated as Competent Persons may be required to initiate entry into cargo tanks and adjacent spaces where no toxic contaminants are suspected to be present. Cargo tank entry shall be permitted after testing reveals acceptable atmospheric conditions.

4.1.4.2. Acceptable test results for unrestricted tank entry are provided in subparagraph 4.1.3.5.

4.1.4.3. Entry into tanks or spaces with acceptable test results may be performed without respiratory protection.

4.1.4.3.1. Entry into tanks containing 1% to 5% LEL shall be performed with the use of half-face organic vapor cartridge respirators provided this level of protection is sufficient for the contaminant.

4.1.4.4. 1910-series personnel shall monitor all fuel tanks to be entered using an atmospheric testing instrument that measures oxygen content, flammable gases and toxic vapors. In spaces that have been previously loaded with fuels, concentration of fuel vapors shall remain below the https://dla1.eportal.dla.mil/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/ewpAgencyDocuments/Private/Field/DESC/Standard%20Operating%20Procedures/DESC-S-D-08-06%20Respiratory%20Protection%20Program.pdf https://dla1.eportal.dla.mil/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/ewpAgencyDocuments/Private/Field/DESC/Standard%20Operating%20Procedures/DESC-S-D-08-06%20Respiratory%20Protection%20Program.pdf

30 ppm for jet fuel and 15 ppm for diesel fuel. If that level is exceeded, either ventilation to restore acceptable conditions or respiratory protection is required.

4.1.4.5. If these limits are violated, the tank shall be rejected for inspection until the atmosphere in the space can be brought to acceptable levels. Cargo compartment inspection delays due to oxygen deficiency or high levels of combustible gas will be reported as a vessel delay.

4.1.4.6. Although OSHA regulations permit unprotected entry into confined spaces with an oxygen content of at least 19.5% by volume, it is DESC policy that no DESC personnel shall enter any confined space without respiratory protection unless the oxygen content is between 20.7%-20.9% (20.8% is optimal). Employees shall investigate any test results other than 20.7%- 20.9% and if possible, ventilate to an acceptable level.

4.1.4.7. Atmospheric Testing. Atmospheric testing shall be performed in accordance with the procedures and techniques set forth in the DESC Confined Space Entry Program:

4.1.4.7.1. Calibration check of atmospheric testing instruments according to manufacture’s specifications.

4.1.4.7.2. Function check of direct-reading instruments before each use.

4.1.4.7.3. Testing for oxygen content first, then flammability, and toxic contaminants last.

4.1.4.7.4. Testing from the top of the space prior to entry and continuous monitoring throughout the duration of the entry.

4.1.4.7.5. The sampling hose shall extend to the bottom of the tank at first, and then continuous monitoring as the hose is withdrawn slowly from the bottom of the tank to the top. The reaction or response time must be predetermined during the function check.

4.1.4.7.6. All cargo system valves must be open and cargo system lines drained and secured, prior to entry.

4.1.4.8. In accordance with the terms of their contract, Military Sealift Command (MSC) and other vessels and crews are not relieved of their responsibility to present the vessel for inspection in a gas free condition. They must not be allowed to become lax on this point. 1910-series personnel testing of the tanks prior to entry should not be construed as usurping the vessel master’s or first mate’s responsibilities for testing the tanks and presenting the vessel in a gas free condition.

4.1.4.9. All tests for oxygen deficiency, flammability, or toxic contaminants conducted by 1910-series personnel in their role as Competent Person must be recorded on a log of inspections and tests. This log must be completed at the time of inspection and maintained for a period of at least three months. Reference Appendix 4, Log of Inspections and Tests, of this document.

4.1.4.10. The atmospheric testing instrument shall be worn at all times throughout the duration of the entry and inspection.

4.1.4.11. An attendant must be present on deck at the top of the tank at all times during the tank entry and inspection procedure, to maintain constant communication with the individual who is in the tank. A member of the ship’s crew may serve in this capacity.

4.1.4.12. Emergency rescue equipment such as self-contained breathing apparatus, retrieval lines, and communications equipment, or other means of summoning help, must be available in the event the entrant becomes injured or incapacitated.

4.1.5. Unusual Situations or Circumstances

4.1.5.1. General. Overseas, there may arise from time to time, in certain regions of the world, an unusual situation or circumstance where the procedures described above might be impractical.

Such a situation might be the inability to carry atmospheric testing instruments into certain regions due to Customs. Also, occasionally, spot charters present special or unusual conditions or situations due to the vessel or the previous cargo carried. All such situations cannot be foreseen or addressed.

4.1.5.2. The following procedures have been approved as acceptable to prevent exposures to any toxic vapors where a Marine Chemist services are not available. These procedures, coupled with organic vapor monitoring procedures are intended to assure the safety of personnel and preclude any over-exposure to benzene or other toxic contaminants.

4.1.5.2.1. Testing Toxic and Non-Toxic Cargos by 1910-Series Personnel

4.1.5.2.1.1. All testing and entry procedures as outlined in subparagraphs 4.1.3 and 4.1.4. shall be completed prior to entry.

4.1.5.2.1.2. All cargo system valves shall be opened and drained prior to entry.

4.1.5.2.1.3. Non-toxic cargos entry is permitted without respiratory protection if acceptable results are obtained. Refer to subparagraph 4.1.3.6. for acceptable test results for unrestricted entry.

4.1.5.2.1.3.1. Toxic cargos entry is permitted only with DESC issued Personal Protective Equipment (PPE).

4.1.5.2.1.4. If contaminants exceed acceptable levels, respiratory protection and/or protective clothing is required.

4.1.5.2.1.5. If the oxygen content is less than 19.5%, flammable gas exceeds 0% LEL, or toxic contaminants exceed the Immedately Dangerous to Life or Health level (IDLH), ENTRY IS

PROHIBITED.

4.1.5.2.2. Testing of cargo tanks and adjacent spaces by the vessel crew only shall be acceptable for 1910-series personnel entry, under the following conditions:

4.1.5.2.2.1. The 1910-series personnel has no available means to perform atmospheric testing.

4.1.5.2.2.2. The vessel crew testing is observed by the 1910-series personnel. The atmospheric testing instrument used must be calibrated and functioning properly.

4.1.5.2.2.3. The individual performing the tests must be competent to perform such testing.

4.1.5.3. Under no circumstances should a tank or space that previously contained an unusual or highly toxic cargo such as liquid benzene, naphtha or leaded gasoline be entered by DESC personnel without toxic testing by a Competent Person, a Marine Chemist, a CIH, or other authorized person capable of conducting toxic testing. Prior to entry, obtain a permit authorizing entry. Entry is conditional upon the authorized person’s instructions.

4.1.6. Non-Marine Confined Space Entry – Permit Required

4.1.6.1. General. This section contains requirements for practices and procedures to protect employees in general industry from hazards of entry into permit-required confined spaces.

4.1.6.1.1. This section does not apply to marine ships and vessels. The requirements and procedures set forth in OSHA Standard, Title 29, CFR Section 1910.146 have been determined to be applicable to any DESC land-based (non-vessel or non-shipyard) permit-required confined spaces.

4.1.6.1.2. Evaluation of the workplace shall be made to determine if any spaces are permit-required confined spaces. Proper application of the decision flow chart in Appendix 3, Permit- Required Confined Space Decision Flow Chart, will facilitate compliance with this requirement.

4.1.6.1.3. If the workplace contains permit spaces, exposed employees must be informed, by posting danger signs or by any other equally effective means, of the existence and location of and the danger posed by the permit spaces.

4.1.6.1.3.1. A sign reading – DANGER—PERMIT-REQUIRED CONFINED SPACE, DO NOT ENTER or other similar language would satisfy this requirement for a sign.

4.1.6.1.4. If the employer, e.g., DESC, contractor or host employer decides that its personnel will not enter permit spaces, the employer shall take effective measures to prevent its personnel from entering the permit spaces and shall comply with subparagraphs 4.1.6.1.2. through 4.1.6.1.3.1., as noted above, and subparagraph 4.1.8.

4.1.6.1.5. If the employer decides that its personnel will enter permit spaces, the employer shall develop and implement a written permit space program that complies with OSHA Standard, Title 29, CFR Section 1910.146. The information on the program shall be available for inspection by personnel and their authorized representatives.

4.1.6.2. Entry Into Permit-Required Confined Spaces

4.1.6.2.1. In accordance with OSHA Standard, Title 29, CFR Section 1910.146(e)(3), the completed permit shall be made available at the time of entry to all authorized entrants or their authorized representatives, by posting the permit at the entry portal or by any other equally effective means, so that the entrants can confirm that pre-entry preparations have been completed.

4.1.6.2.2. Any entry into permit-required confined spaces will be authorized only after the following measures have been completed:

4.1.6.2.2.1. An entry permit has been prepared in accordance with subparagraph 4.1.7. of this document.

4.1.6.2.2.2. The atmosphere in the space has been tested for oxygen and LEL. Entry without appropriate respiratory protection shall be permitted only if there is at least 20.7-20.9% oxygen, the LEL is at or below 5%, and toxic contaminants are below the Threshold Limit Value (TLV) or Permissible Exposure Limit (PEL).

4.1.6.2.2.2.1. Reference subparagraph 4.1.3.5. for further guidance on acceptable test results for unrestricted tank entry.

4.1.6.2.2.3. Entry into tanks or spaces with acceptable test results may be performed without respiratory protection.

4.1.6.2.2.3.1. Entry into tanks containing 1% to 5% LEL shall be performed with the use of half-face organic vapor cartridge respirators, provided this level of protection is sufficient for the contaminant.

4.1.6.2.2.4. If entry into the space is to be made before the above atmospheric levels can be attained, entry shall be made only with appropriate, approved respiratory protection.

4.1.6.2.2.5. Employees who may be required to wear a respirator must be enrolled in a respiratory protection program as described in the DESC-S-D-08-06, DESC Respiratory Protection Program SOP.

4.1.6.2.2.6. No entry shall be made into any space that contains an IDLH condition or atmosphere unless for the purpose of rescue of another entrant, and then only by trained personnel with appropriated respiratory and emergency equipment.

4.1.6.2.2.7. An attendant will be assigned to the permit space for the duration of the entry operation. The attendant will maintain continuous contact with the entrant(s) and will have communications available to summon rescue or other emergency services if necessary.

https://dla1.eportal.dla.mil/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/ewpAgencyDocuments/Private/Field/DESC/Standard%20Operating%20Procedures/DESC-S-D-08-06%20Respiratory%20Protection%20Program.pdf https://dla1.eportal.dla.mil/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/ewpAgencyDocuments/Private/Field/DESC/Standard%20Operating%20Procedures/DESC-S-D-08-06%20Respiratory%20Protection%20Program.pdf

4.1.6.2.2.7.1. Rescue Services. Arrangements shall be made with local emergency fire and medical services to provide emergency rescue services if needed. These organizations are required to be familiar with the designated spaces on the facility and the hazards of any permit spaces.

4.1.6.3. Atmospheric Testing Instruments. The atmosphere of a confined space shall be analyzed using equipment of sufficient sensitivity and specificity to identify and evaluate any hazardous atmospheres that may exist or arise, and to ensure compliance with permit entry procedures and acceptable entry conditions. 1910-series personnel shall monitor all fuel tanks to be entered with a calibrated atmospheric testing instrument provided by DESC. This instrument will test for oxygen, flammability, and toxic contaminates. In spaces that have been previously loaded with fuels, concentrations of fuel vapors shall remain below 30 ppm. If the level exceeds, either ventilate to restore to acceptable conditions or require respiratory protection.

4.1.6.3.1. The atmospheric testing instrument shall be worn at all times throughout the duration of the entry. If the oxygen, LEL, carbon monoxide or hydrogen sulfide alarm activates, the entrant must exit the space immediately.

4.1.7. Entry Permit System. Prior to authorizing entry into any permit space, an entry permit shall be prepared. Reference Appendix 5, Sample Confined Space Entry Permit. Depending on the authorized entrant, either a contractor employee or the 1910-series personnel will prepare and sign the permit.

4.1.7.1. An Entry Permit shall be obtained from the entry supervisor prior to confined space entry.

4.1.7.2. Examples of permit spaces at petroleum terminals would be boilers, storage tanks, tank cars and trucks, tunnels, pits, manholes, sewers and floating roof tank tops under certain weather conditions and configurations, such as at low roof position (8 ft or less above minimum elevation).

4.1.7.3. Doorways and other portals through which a person can walk are not considered to be limited means for entry and exit. OSHA has emphasized that OSHA Standard, Title 29, CFR Section 1910.146 is directed toward work areas such as those with hatches and narrow passageways, whose configurations exacerbate employee risk by slowing evacuations and rescues.

4.1.7.4. OSHA also makes it clear that the work areas covered by this standard are unsuitable, by nature of continuous employee occupancy, because those spaces were created to contain such things as sewage, degreasers, toxic chemicals and petroleum products. OSHA states that few employers, if any, whose workplaces contain permit required spaces, could both maintain those spaces safe for entry and use the permit spaces for their intended purpose.

4.1.7.5. Entry Permit Information. The entry permit shall contain:

4.1.7.5.1. The date, location of permit space, and time period covered by the permit.

4.1.7.5.2. The purpose of the entry.

4.1.7.5.3. The hazards of the permit space and the measures taken to ensure isolation of the space.

4.1.7.5.4. The measures taken such as flushing and ventilation to remove or control the hazards.

4.1.7.5.5. The calibrated direct-reading instrument and testing frequency, to assure acceptable conditions are maintained. Reference subparagraph 4.1.3.5. for further information regarding acceptable test results for unrestricted tank entry.

4.1.7.5.5.1. Entry into tanks or spaces with acceptable test results may be performed without respiratory protection.

4.1.7.5.5.2. Entry into tanks containing 1% to 5% LEL shall be performed with the use of half-face organic vapor cartridge respirators, provided this level of protection is sufficient for the contaminant.

4.1.7.5.6. Emergency personnel rescue or other services that will be summoned in case of emergency, and the means of communication with those services, and the equipment to be provided on-site, if necessary.

4.1.7.5.7. Communication procedures and equipment used by the entrants and attendants to maintain contact and the personal protective equipment, such as respirators, shall be provided in order to ensure employee safety.

4.1.7.5.7.1. The name(s) of the authorized entrant(s).

4.1.7.5.7.2. The name(s) of the assigned attendant(s).

4.1.7.5.7.3. The name and signature of the entry supervisor or individual in charge of the entry, verifying that all actions and conditions necessary for the safe entry have been performed. For Government-Owned, Contractor-Operated (GOCO) facilities the entry supervisor would include the terminal superintendent for contractor personnel entry, the 1910-series personnel for their own entry, and the subcontractor’s worksite supervisor for entry by other subcontractor personnel.

4.1.8. Entry Into Confined Spaces – Non-Permit Spaces

4.1.8.1. General. A “non-permit” confined space means a confined space that does not contain or, with respect to atmospheric hazards, have the potential to contain any hazard capable of causing death or serious physical harm.

4.1.8.2. A space classified by the employer as a permit-required confined space may be reclassified as a non-permit confined space under the following conditions:

4.1.8.2.1. If the permit space poses no actual or potential atmospheric hazards and if all hazards within the space are eliminated without entry into the space, the permit space may be reclassified as a non-permit confined space for as long as the non-atmospheric hazards remain eliminated.

4.1.8.2.2. If it is necessary to enter the permit space to eliminate hazards, such entry shall be performed under subparagraph 4.1.6.2. of this document. If the testing and inspection during that entry demonstrates that the hazards within the permit space have been eliminated the permit space may be reclassified as a non-permit space for as long as the hazard remains eliminated.

4.1.8.2.2.1. Control of atmospheric hazards through forced air ventilation does not constitute elimination of hazards.

4.1.8.2.3. The employer shall document the basis for determining that all hazards in a permit space have been eliminated through:

4.1.8.2.3.1. A certification that contains the date.

4.1.8.2.3.2. The location of the space.

4.1.8.2.3.3. The signature of the person making the determination.

4.1.8.2.3.4. The certification shall be made available to each employee entering the space or to that employee’s authorized representative.

4.1.8.2.4. If hazards arise within a permit space that has been declassified to a non-permit space, each employee in the space shall exit the space. The employer shall reevaluate the space and determine whether it must be reclassified as a permit space.

4.1.8.2.5. Examples of potential non-permit spaces would be floating roofs of fuel tanks above the low roof position (8 feet or less above minimum elevation), dike areas of tanks, open well-ventilated valve pits.

4.1.8.2.6. Where a non-permit space has been identified, entry may be authorized into the space for a period of up to one year, provided that:

4.1.8.2.7. Compliance with the basic program elements of the Permit-Required Confined Space Program have been met.

4.1.8.2.8. The basic program elements are described in OSHA Standard, Title 29, CFR Section

1910.146 and includes hazard identification and control, an established permit system, employee information and training, prevention of unauthorized entry, and personal protective equipment.

4.1.8.2.9. An entry permit for that space has been properly prepared stipulating the time period covered by that permit, as described in subparagraph 4.1.7.6. of this document.

4.1.8.2.10. All entry into low-hazard spaces shall be conducted in accordance with American Petroleum Institute (API) Publication 2217, Guidelines for Confined Space Work in the Petroleum Industry; API Publication 2026, Safe Descent onto Floating Roofs of Tanks in Petroleum Service; and American National Standards Institute (ANSI) Standard Z177.1-1977, Safety Requirements for Working in Tanks and other Confined Spaces.

4.1.8.2.11. The entrant must ensure that there has been no release of product into the space which would cause a hazard to be present. The atmosphere in the space shall be tested for oxygen deficiency, flammable gases and vapors, and toxic air contaminates. Entry shall be permitted only if there is at least 19.5% oxygen, flammable vapors are at or below 5% LEL and the concentration of contaminants and the duration of exposure are below the TLV or PEL for any toxic material.
