NIOSH Horizontal Multiplier Lookup
RNLE horizontal multiplier25/max(25, H), reject beyond 63cm rather than assert applicable lifting model. Caller independently establishes matching units, evidence, method edition and applicability; output is not compliance, diagnosis, work-safety approval, geological identity or validated hazard prediction.
Description
The NIOSH horizontal multiplier reduces a lifting-model allowance as horizontal reach increases.
The NIOSH horizontal multiplier reduces a lifting-model allowance as horizontal reach increases.1
A short measured reach is clamped to the formula's reference distance in this implementation. Use this tool to calculate NIOSH Horizontal Multiplier Lookup from the supplied measurements and assumptions.
When to use NIOSH Horizontal Multiplier Lookup
Use this tool to calculate NIOSH Horizontal Multiplier Lookup from the supplied measurements and assumptions. Establish the observation protocol, units, task and reference population or review criterion before entering measurements.
How to use NIOSH Horizontal Multiplier Lookup and understand its results
- Establish the observation protocol, units, task and reference population or review criterion before entering measurements.
- Enter horizontalReachCm, using the field meanings and rules below, then run the tool.
- Read horizontalMultiplier. Interpret the fields using their units, signs and evidence conventions below.
- If input validation fails, correct the reported field and run again. Before applying the result, check reference scope, model assumptions and any missing evidence or placeholder values.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| horizontalReachCm | Horizontal reach cm | number | Required |
Enter horizontal distance in cm from zero through 63. Clamp it upward to 25 cm, then divide 25 by the clamped distance. The accepted short-distance branch returns 1 rather than a multiplier above 1.
HM=25/max(25,Hcm) Use the exact units, boundary rules, ordering and missing-evidence conventions above.
| Output field | Meaning | Value type |
|---|---|---|
| horizontalMultiplier | Horizontal Multiplier; follow the units, sign, ordering and evidence convention stated above | number |

}Limitations and assumptions
A short measured reach is clamped to the formula's reference distance in this implementation. Interpretation depends on the units, sampling scope and exact model described above.
All listed fields require explicit values. Unexpected fields, incorrect types, nonfinite numbers and sparse evidence arrays fail validation; the specific bounds and alignment requirements are stated above. Extremely large inputs or outputs can also be rejected. An input error is distinct from a successful result reporting false, no matches or missing evidence.
Alternative or Complementary methods
Use NIOSH Vertical Multiplier Lookup for this related task: The NIOSH vertical multiplier adjusts a lifting model for hand height relative to its reference height.
Use NIOSH Distance Multiplier Lookup when its separate inputs and assumptions fit the question: The NIOSH distance multiplier accounts for vertical travel distance within a lifting model.
