Description
Return distinct-role coverage for a drill.
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 distinct-role coverage for a drill.
When to use this tool
Use Drill Role Coverage Share when checking the stated laboratory-safety record, timing, capacity or inventory convention.
How to use the tool and how it works
- Enter requiredRoles, presentRoles. Follow any array-alignment requirements below. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read covered, required, share, defined. Inspect defined before interpreting the associated values.
Return distinct-role coverage for a drill. Deduplicate requiredRoles and literal present-role matches; covered/required form share, otherwise zero with defined false.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| requiredRoles | Required Roles | Required. Array of text; maximum UTF-16 length 8192; maximum items 256. |
| presentRoles | Present Roles | Required. Array of text; maximum UTF-16 length 8192; maximum items 256. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| covered | Covered | Required. Safe integer. |
| required | Required | Required. Safe integer. |
| share | Dimensionless numerator/denominator ratio under the explicit basis above. | Required. Finite number. |
| defined | Reporting flag under the explicit denominator or information policy above; inspect any zero placeholder or policy-defined value. | Required. Boolean. |

}Limitations and assumptions
- Presence labels are supplied, not distinct people, verified participation, competence or evidence of safe readiness.
- 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.
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.
