Description
Return a quantity-gap envelope from supplied counting half-width.
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.
Return a quantity-gap envelope from supplied counting half-width.
When to use this tool
Use Biosafety Reported Actual Quantity Gap when checking the stated laboratory-safety record, timing, capacity or inventory convention.
How to use the tool and how it works
- Enter reported, counted, countHalfwidth. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read nominalGap, minimumGap, maximumGap. Use the output convention below.
Return a quantity-gap envelope from supplied counting half-width. Require reported/counted/halfwidth >= 0; nominalGap = counted-reported, minimum/maximumGap add minus/plus halfwidth.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| reported | Reported | Required. Finite number; minimum 0. |
| counted | Counted | Required. Finite number; minimum 0. |
| countHalfwidth | Count Halfwidth | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| nominalGap | Nominal Gap | Required. Finite number. |
| minimumGap | Minimum Gap | Required. Finite number. |
| maximumGap | Maximum Gap | Required. Finite number. |

}Limitations and assumptions
- This is a deterministic supplied range, not a confidence interval or verification of actual inventory and safe containment.
- 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.
