Description
Check a protective-training expiry boundary.
Laboratory-safety administration tracks inspection records, equipment counts, training coverage and supplied policy limits. A local balance or current-status flag can reveal a record gap while actual equipment condition, training competence and adequate protection require independent verification.
Check a protective-training expiry boundary.
When to use this tool
Use Protective Training Expiry Margin when checking the stated laboratory-safety record, timing, capacity or inventory convention.
How to use the tool and how it works
- Enter expiry, reviewedAt, inclusiveExpiry. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read remaining, currentUnderRule. Inspect currentUnderRule before interpreting the associated values.
Check a protective-training expiry boundary. remaining = expiry-reviewedAt; currentUnderRule uses <= when inclusiveExpiry, otherwise strict <.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| expiry | Expiry | Required. Finite number. |
| reviewedAt | Reviewed At | Required. Finite number. |
| inclusiveExpiry | Inclusive Expiry | Required. Boolean. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| remaining | Budget minus use under the stated direction, retaining negative deficits where allowed. | Required. Finite number. |
| currentUnderRule | Current Under Rule | Required. Boolean. |

}Limitations and assumptions
- This predicate does not require a valid-from date or verify completed training, competence or adequate protective practice.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Inspect actual equipment and verified records under the applicable procedures; use qualified risk assessment and professional judgment to determine adequate protection and actual authorization.
