How to use this document
Copy the template below into your quality system. Replace every <<FILL: ...>> placeholder with your company, system, and process specifics, then route it through your own document control, review, and approval. The filled specimen shows one worked example; adapt the numbers and scope to your operation and verify each cited regulation or standard against the current source before you rely on it.
This is a generic, originally worded starting point. It contains no confidential, proprietary, or employer material, it is drafted with AI assistance and reviewed, it is not legal or compliance advice, and adopting it does not by itself create or prove compliance. See the Disclaimer and Terms.
This is a ready-to-use risk assessment for selecting a container closure integrity test (CCIT) method and deriving its maximum allowable leakage limit (MALL), the document the CCIT Study Protocol’s “linked method selection risk assessment” field points back to. Replace every <<FILL: ...>> placeholder with your own specifics and route it through your normal document control, review, and approval. A worked filled specimen follows. Verify each cited reference against the current source before you rely on it.
1. Purpose
This assessment documents the basis for the CCIT method selected for <<FILL: product>>, and derives the maximum allowable leakage limit (MALL) that method has to detect below, so both decisions rest on a scored, evidenced rationale rather than default practice or the equipment already on hand.
2. Scope
3. Responsibilities
4. Method selection logic
Work the three USP <1207.1> questions in order; each answer narrows the field before the next is asked.
5. MALL derivation
6. Candidate method scoring
Score each candidate method against the container system in scope. A method scoring “No” on physical applicability is eliminated regardless of how it scores elsewhere.
7. Positive control basis
8. Residual risk and acceptance
9. References

Filled specimen
Extract for an example 1 mL prefilled syringe of a conductive, oxygen-sensitive biologic, glass barrel, staked needle, rigid needle shield, no nitrogen overlay. Company and product are illustrative.
Method selection logic: critical attributes are sterility and oxygen ingress, the latter carried entirely by the seal since there is no headspace nitrogen overlay. The fill is conductive, confirmed by a bench conductivity check, which gives HVLD physical access; no headspace exists, which eliminates headspace gas analysis outright regardless of its other merits. The format’s line speed supports 100 percent in-line HVLD scanning rather than a sampled off-line program.
MALL derivation: the sterility-driven MALL follows standard sub-micron, correlation-study-anchored logic, confirmed separately by helium correlation during development. The oxygen-driven MALL is tighter than a larger-headspace format would require, landing in the low single-digit micron range because the same absolute oxygen ingress represents a larger fractional change in this syringe’s small effective headspace. The governing MALL for routine HVLD acceptance criteria is the oxygen-driven limit; the sterility MALL is carried by the separate helium correlation data, not claimed against the routine HVLD curve.
Residual risk: HVLD independently interrogates the plunger seal and the needle-shield seal as two separate scan zones, closing the single-seal-thinking gap common to PFS programs; no residual risk accepted without mitigation.
Common inspection findings this risk assessment prevents
- A method selected because it was already on hand, with no record that the three USP <1207.1> selection questions were actually asked.
- A MALL asserted with no stated basis, sterility or otherwise.
- A probabilistic method retained by default with no documented rationale for why no deterministic method was feasible.
- A multi-seal container’s second seal never separately scored in the method-fit register.
How to adapt this risk assessment
- Set your document number, product, and container system in the header.
- Work section 4’s three questions honestly and in order; do not skip to a method because it is familiar.
- Derive both MALLs in section 5 from real risk logic, sterility correlation data and a stability-driven gas or moisture limit, not a copied number.
- Score every seal location on a multi-seal format separately in section 6; do not let one seal’s result stand in for another.
- Confirm every USP chapter reference in section 9 against the current published version before issue.
