What you need to know
Use 33 CFR 105.545 -- Maritime Security: Facilities to review this narrow operational decision without extending the source beyond its stated scope.
Potentially affected
Teams, systems, services, or facilities within the stated scope of 33 CFR 105.545 -- Maritime Security: Facilities
DSE recommendation
Compare the observed state with the cited official source, document applicability and exceptions, and test any approved change with rollback safeguards.
Use this document to connect an official requirement or behavior to observable evidence: Select, test, and maintain cruise-terminal screening equipment for its approved use. Only the official source and traced locations below supply facts. Confirm applicability before acting.
Source fact:
The official 33 CFR 105.545 — Maritime Security: Facilities from U.S. Coast Guard via eCFR supports the following bounded statements:
- Under 33 CFR 105, the owner or operator of a cruise ship terminal may use an x-ray system for the screening and inspection of personal effects and baggage if all of the following requirements are satisfied: the owner or operator must ensure that a sign is posted in a conspicuous place at the screening location where x-ray systems are used to inspect personal effects and where screeners accept baggage. The research record locates this support at 33 CFR 105.545(b)(6), read with 33 CFR 105.545(b) (eCFR anchor p-105.545(b)(6)).
- Under 33 CFR 105, the rule requires that all explosives detection equipment used at a cruise ship terminal be operated, calibrated, and maintained in accordance with manufacturer’s instructions. The research record locates this support at 33 CFR 105.545(c)(2) (eCFR anchor p-105.545(c)(2)).
The source support ends with the statements listed above. Use them to examine critical rooms, power, cooling, water, fire protection, alternate sites, physical barriers, and documented recovery paths in the applicable environment, not to imply a wider guarantee.
What the source does not establish
Applies only to facilities within 33 CFR part 105 and the cited section. Confirm Coast Guard jurisdiction, the approved Facility Security Plan, the current MARSEC level, and any approved alternatives; this is not legal advice or a universal facility-design standard. The citation is not a substitute for observed state, authorization, compliance evidence, or dependency health. Examine identity and access control, Windows DNS where networked services use it, time, communications, utilities, life-safety systems, vendors, and authorized responders before translating the source into an operational decision.
Applicability questions
- For source statement 1 at 33 CFR 105.545(b)(6), read with 33 CFR 105.545(b) (eCFR anchor p-105.545(b)(6)), which observable configuration, record, or test can confirm applicability here?
- For source statement 2 at 33 CFR 105.545(c)(2) (eCFR anchor p-105.545(c)(2)), which observable configuration, record, or test can confirm applicability here?
- Which owner can attest to the recorded state of critical rooms, power, cooling, water, fire protection, alternate sites, physical barriers, and documented recovery paths, including exceptions?
- What baseline for identity and access control, Windows DNS where networked services use it, time, communications, utilities, life-safety systems, vendors, and authorized responders must accompany the source-specific observation?
- Which success, stop, and escalation criteria are written before testing begins?
DSE recommendation:
DSE recommends using the cited source as the evidence anchor for this decision. Make the source, asset scope, owner, and expected outcome explicit in the review record. Record the source location, examined part of critical rooms, power, cooling, water, fire protection, alternate sites, physical barriers, and documented recovery paths, observed and expected states, owner, and reason for deviation.
For an approved change, define prerequisites, a limited test path, success and stop conditions, monitoring, and rollback. Check identity and access control, Windows DNS where networked services use it, time, communications, utilities, life-safety systems, vendors, and authorized responders in design order. Protect credentials, keys, recovery material, personal data, and sensitive topology in evidence.
Verification and evidence
Build a reproducible chain from 33 CFR 105.545(b)(6), read with 33 CFR 105.545(b) (eCFR anchor p-105.545(b)(6)); 33 CFR 105.545(c)(2) (eCFR anchor p-105.545(c)(2)) to the observed environment. Useful domain evidence includes facility inventories, inspection records, alarm and shutdown tests, maintenance history, recovery exercises, and corrective actions; label every item with scope, timestamp, collector, and stable identifier.
Retain the starting state, authorization, execution record, outcome, deviation, and final state as one review package. Move disruptive checks to an approved test path. Reopen the decision when versions, design, dependencies, ownership, or official guidance changes.
