man 10 cards Flashcards
What is an example of a 1D card?
- If a compressors used for primary/secondary air becomes inoperable, a Category ID SCSC should be issued against that compressor, but the system would retain its certification
What can happen if a 1D card is received?
- Some limitation may be placed on the operational parameters of the existing certification
Is there a specified time a 1D card has to be accomplished by?
- No
- The status of all outstanding ID SCSCs shall be reviewed at the next on-site survey
What if a 1D discrepancy has not been resolved by the next on-site survey?
- The SCA shall, at the request of the diving command, consider removing the component from the SOC, and possibly downgrading the capabilities of the system.
What are some reasons to receive a 1A card?
- Lack of system cleanliness verification
- Lack of hydrotest data and/or inspection records for newly installed components or for periodic inspection/retest of pressure vessels (i.e., gas flasks, volume tanks, moisture separators, filter housings)
- Unqualified weld/NDT procedures or personnel
- Unsatisfactory test/inspection results
- Damaged or non-operational pressure boundary components
- Unauthorized system modifications
- Major system drawing discrepancies
- Operating and emergency procedures not approved
- Inaccessible vital components
- Inadequate re-entry control program
- Pressure piping chafing on other piping or components such that damage could result
- Unauthorized sealing compound on pipe threads
- Lack of emergency power when required to provide sufficient breathing gas from electrically driven compressors
What are some reasons to receive a 1B card?
- Unable to perform operational demonstration due to logistical problems
- Difficult access to or operation of system components
- Unapproved preventive maintenance procedures
- No OQE available for replacement component
- Brazer/welder qualifications not available for review
- Newly installed components that are not in accordance with approved drawings
- Administrative errors or omissions on SOC documentation
What are some reasons to receive a 1C card?
- System drawings not updated to reflect as-built configuration of system
- Label plates missing from system valves
- System valve hand wheels/piping not color coded
- Permanent label plates not installed on diver connections
- Dust caps not provided at diver hose connections
Survey findings that typically fall into the IB category on an uncertified system are generally considered what category findings on a certified system?
1A or 1C
What is required prior to a manned demonstration?
Unmanned demonstration
- The length of time between overhauls of a particular facility shall be determined by the activity, applicant and SCA, but shall not exceed how many years, unless written technical justification is provided by the applicant and approved by the SCA?
- 10 years
Whose signature is required as administrative approval for re-entry and verification that work was satisfactorily completed?
- The Diving Officer
Who can the Diving Officer give signature authority to?
- Senior Diving Supervisor
When is the Commanding Officers signature required?
- Prior to any manned operations of a certified DLSS after a maintenance action.
\Who can the Commanding Officer give signature authority to?
- The Diving Officer
When can the Commanding Officer’s signature not be delegated?
- When requesting major departure from specification
