Description
Return downtime union and scheduled availability.
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 downtime union and scheduled availability.
When to use this tool
Use Biosafety Maintenance Downtime Share when checking the stated laboratory-safety record, timing, capacity or inventory convention.
How to use the tool and how it works
- Enter scheduledHours, plannedDown, unplannedDown, overlappingDown. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read downHours, availableHours, availability. Use the output convention below.
Return downtime union and scheduled availability. Require scheduledHours > 0, nonnegative downtime/overlap and feasible union <= scheduled; downHours = planned+unplanned-overlap, available subtracts union, availability divides by schedule.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| scheduledHours | Scheduled Hours | Required. Finite number; strictly above 0. |
| plannedDown | Planned Down | Required. Finite number; minimum 0. |
| unplannedDown | Unplanned Down | Required. Finite number; minimum 0. |
| overlappingDown | Overlapping Down | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| downHours | Down Hours | Required. Finite number. |
| availableHours | Available Hours | Required. Finite number. |
| availability | Availability | Required. Finite number. |

}Limitations and assumptions
- Time categories and overlap are supplied; availability does not certify equipment safety, reliability or maintenance quality.
- 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.
