Description
Return duration=breakEnd-breakStart and gap=duration-requiredDuration.
Occupational exposure calculations combine measured quantities, duration, reference conditions, weighting, and sampling support. Linear concentrations, squared acceleration, and logarithmic sound levels require different arithmetic. A supplied reference or limit is not automatically the applicable standard, and a local calculation is separate from a full exposure and safety assessment.
Return duration=breakEnd-breakStart and gap=duration-requiredDuration.
When to use this tool
Use Shift Break Window Gap when you need this particular sampling, duration, reference-unit, physical-exposure, or reporting-base term.
How to use the tool and how it works
- Enter breakStart, breakEnd, requiredDuration. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read duration, gap. Use the output convention below.
Require breakEnd>=breakStart and nonnegative requiredDuration. Return duration=breakEnd-breakStart and gap=duration-requiredDuration.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| breakStart | Break Start | Required. Finite number. |
| breakEnd | Break End | Required. Finite number. |
| requiredDuration | Required Duration | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| duration | Nonnegative time interval in a unit compatible with the reference duration. | Required. Finite number. |
| gap | Signed difference under the stated formula. | Required. Finite number. |

}Limitations and assumptions
- Times and required duration need one unit and origin. The requirement is supplied rather than a statutory or medical recommendation; a sufficient interval does not verify that a break occurred or was restorative.
- 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
Use a complete hazard-specific assessment with calibrated measurements and the appropriate exposure model. Verify reference conditions, sampling coverage, weighting, denominator, and the applicable professional or regulatory method.
