OCRA Technical Action Frequency per Minute Calculator
Aggregate observed technical actions under caller classification and actual active-time denominator, not all movements or clock-shift time; does not compute a full OCRA index or safe repetitive-work limit.
Description
Technical-action frequency pools caller-classified actions over actual active minutes.
Technical-action frequency pools caller-classified actions over actual active minutes. Clock-shift duration would give a different denominator.1
Enter aligned nonempty nonnegative integer counts, binary qualification flags, positive active minutes and nonnegative caller maximum. Return safe-integer qualifying count, pooled frequency and strict exceedance.
When to use OCRA Technical Action Frequency per Minute Calculator
Use OCRA Technical Action Frequency per Minute Calculator when you need to evaluate the supplied records under the calculation and evidence rules below. No complete OCRA index or safe repetitive-work limit is calculated.
Prepare measured task, body, furniture or already weighted exposure records. Supply independently verified caller policies, tables and comparison limits with matching units and conditions.
How to use OCRA Technical Action Frequency per Minute Calculator and understand its results
- Prepare measured task, body, furniture or already weighted exposure records. Supply independently verified caller policies, tables and comparison limits with matching units and conditions.
- Enter observedActionCounts, qualifyingTechnicalActionFlags, observedActiveMinutes, callerMaximumTechnicalActionsPerMinute using the field table and calculation rules, then run the tool.
- Read totalQualifyingTechnicalActions, observedActiveMinuteFrequency, aboveCallerFrequencyLimit. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| observedActionCounts | Observed action counts | list of number | Required |
| qualifyingTechnicalActionFlags | Qualifying technical action flags | list of number | Required |
| observedActiveMinutes | Observed active minutes | list of number | Required |
| callerMaximumTechnicalActionsPerMinute | Caller maximum technical actions per minute | number | Required |
Enter aligned nonempty nonnegative integer counts, binary qualification flags, positive active minutes and nonnegative caller maximum. Return safe-integer qualifying count, pooled frequency and strict exceedance.
frequency=sum(count×qualifyingFlag)/sum(activeMinutes) Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| totalQualifyingTechnicalActions | Total qualifying technical actions | number |
| observedActiveMinuteFrequency | Observed active minute frequency | number |
| aboveCallerFrequencyLimit | Above caller frequency limit | boolean |

}Limitations and assumptions
No complete OCRA index or safe repetitive-work limit is calculated.
Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Numeric lists are limited to 10,000 entries; string lists to 128 strings of at most 128 characters each. The rules above may impose smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors. A successfully returned false flag is an evaluated outcome; its meaning is explained above.
Alternative or Complementary methods
Use Eye Blink Rate Dry-Eye Screen Time Risk Checker: Complete-blink frequency requires counted blinks and actual observed time. A pooled rate weights each interval by duration. For a complementary task, use Work-Rest Cycle Energy Expenditure Average Calculator: A mixed work/rest cycle uses time weighting to combine metabolic demand. Rest classification and its energy rate are separate evidence.
