What's New in NLE Calc

2.0.4

August 19, 2024

- User Interface updates - Workflow updates

User reviews

Inputs do not work

The destination fields are blocked for vertical distance and asymmetry. The calculations cannot be done without that data.

Lack of usability

User interface needs improvement, was required to use for a class and was disappointed.

Sending hate from America

Hate

Okay, but some simple improvements needed

The user interface is easy and generally understandable. Very good for quick assessments.

There is an error with the tabs calculation details and recommendations: the content is reversed between the two.

The main improvement that is needed is a way to get the results out of the app so the records can be retained and consolidated. Without that capability, it cannot be widely used!

How accurate is NLE Calc?

The app is based on the Applications Manual for the Revised NIOSH Lifting Equation (Pub No. 94-110), a widely recognized standard for assessing lifting ergonomics. The accuracy relies on correct input of task parameters.

Does NLE Calc have ads?

No, NLE Calc does not contain advertisements. It is a free utility provided by the Centers for Disease Control and Prevention.

What is the age rating for NLE Calc?

NLE Calc has an age rating of 4+. This indicates it is suitable for users of all ages, with no content restrictions.

Where can I find more information about the NIOSH Lifting Equation?

The app refers users to the Applications Manual for the Revised NIOSH Lifting Equation publication for detailed examples and explanations of the calculations and their implications.

What does a Lifting Index (LI) of 1 or less mean in NLE Calc?

NIOSH recommends a Lifting Index (LI) of 1 or less for protecting workers from physical stress. An LI of 1 or less suggests that the lifting task is within acceptable limits for preventing low back musculoskeletal disorders.
