Ergonomic evaluation refers to the process of identifying potential risks of your working environment.
Ergonomic evaluation tools are employed to specify the components of risk and find measurable improvement hence managing the proper and comfortable working environment for your employees.
If you’re registered with injuries like strains, tendonitis, carpal tunnel syndrome, or even request for pain relief by your workers, you’ve already found out the prospective ergonomic issues.
You must have known that a large percentage of health, safety, and environment are lost by these ergonomic factors harming a significant portion of your production.
Lately, physical injuries of the workers are not commonly reported in the workplace, musculoskeletal issues are in the verse of rising due to frequent motions like twisting, pushing, lifting, pulling, poor posture, continuous sitting, and so on, though.
A regular ergonomic assessment of your workplace assures your working environment to be safer, healthier, and more productive, lowering the prospective risks.

10 Most Recommended Ergonomic Evaluation Tools
Here is a list of 10 most recommended ergonomic evaluation tools, most of them are available online, choose them, they’re the keys to the success of your objectives and long term aims.
1. WISHA Lifting Calculator
Developed by the Washington State Department of Labor and Industries, WISHA Lifting Calculator can be used to perform ergonomic risk assessments on a wide variety of manual lifting and lowering tasks and can be also used as a screening tool to identify lifting tasks that should be analyzed using the more inclusive NIOSH Lifting Equation.
It’s a very effective and practical risk assessment tool for manual material handling tasks.
It can calculate the maximum accepted load that all the workers on average can lift or put down and by evaluating the variables of given tasks, it can lower the risk of musculoskeletal disorders which are related to the risk of lifting.
Based on NIOSH Lifting Equation, the lifting index it shows is calculated to assume the level of physical stress and musculoskeletal disorders risk related to manual lifting tasks assessed.
A lifting index value of 1.0 or less indicates a nominal risk to health workers, and a lifting index greater than 1.0 shows that the task is of high risk for some fraction of employees, and the rising level of the lifting index demonstrates the higher level of risk for the employees.
This tool emphasizes heavy, frequent, or awkward lifting tasks and uses the variables like duration and frequency of lifting, vertical or horizontal hand positions, weight, and twisting to score the task.
Why We Recommend WISHA Lifting Calculator:
- It’s easy to use as it’s formatted in a one-page layout
- It focuses on the beginning of the lift where there is the highest risk
- It offers you guidance
- It applies fewer variables compared to the NIOSH lifting equation

It evaluates distinct ricks of the caution zone such as awkward job postures, highhanded force, highly repetitive motion, repeated impact, heavy, frequent or awkward lifting, and moderate to high arm vibration and makes the employees cautious about the prospective risks that they may undergo while performing certain tasks for a certain period.
This tool is very significant as it enlists potential caution zones and describes each of them in detail so that the possible risks of the workplace could be avoided.
If you would like to make your employees cautious about such risks, here are some descriptions of cautious situations from the checklist:
- Working with the hand(s) above the head, or the elbow(s) above the shoulders more than 2 hours total per day
- Working with the neck or back bent more than 30 degrees (without the support and without the ability to vary posture) more than 2 hours total per day
- Squatting more than 2 hours total per day
- Kneeling more than 2 hours total per day
- Pinching an unsupported object(s) weighing 2 or more pounds per hand, or pinching with a force of 4 or more pounds per hand, more than 2 hours total per day (comparable to pinching half a ream of paper)
- Gripping an unsupported object(s) weighing 10 or more pounds per hand, or gripping with a force of 10 or more pounds per hand, more than 2 hours total per day (comparable to clamping light-duty automotive jumper cables onto a battery)
3. NIOSH Lifting Equation
An ergonomic evaluation tool, NIOSH Lifting Equation is used by occupational health and safety professionals to evaluate the manual handling risks associated with lifting and lowering tasks in the workplace.
This agronomic assessment tool regards job task variables to assure safe lifting practices and guidelines.
The Recommended Weight Limit, a primary product of the NIOSH lifting equation, identifies the maximum acceptable weight that almost all healthy employees could lift throughout an eight-hour shift without being exposed to the risk of musculoskeletal disorders to the lower back.
The lifting index, on the other hand, is calculated to assume the level of physical stress and musculoskeletal disorder risk related to the manual lifting tasks evaluated.
It’s an assessment tool especially pertinent for manual material handling tasks.
It’s widely accepted as a valid tool in the field of occupational ergonomics that provides occupational health specialists an objective ergonomic risk assessment tool.
NIOSH task variables are needed to calculate the horizontal location of the object relative to the body, vertical location of the object relative to the floor, a distance of the object moved vertically, asymmetry angle or twisting requirement, frequency and duration of lifting activity, and coupling or quality of the worker’s grip on the object.

It’s simple and easy to use with some practice; otherwise, you can take training shortly.
If this tool shows you no positive findings identified, your workplace or the job you’re doing is considered safe and healthy.
However, when a moderate level of risk is shown, the job or task or the working environment is to be evaluated by using a hazard zone checklist to improve the condition of the job or working environment.
By deploying this screening tool, you can determine if a typical work activity exposes your workers with a musculoskeletal disorder, its magnitude, and duration.
Therefore, it helps you to identify the risk and improve the working environment.
Safety is important for you and your workers and a healthy working environment is what you require for the better performance of your industry or business, so why delay, adopt the tools, and feel safe.
So, these are the 10 most recommended ergonomic evaluation tools that you may use to assure the safety of your working environment.
Reading all the descriptions above, you must have understood that your job involves frequent motion, your workers feel pain, discomfort, get tired, feel unsafe, and so on.
If so, you must have thought of using the best ergonomic evaluation tool that assesses and identifies all the discomforts associated with your worker, you, or your working environment, that’s good, you’re on the right track.
Because, naturally, many of our works are highly repetitive, they require force, and distinct postures and we tend to repeat them daily or let’s say hourly and we don’t assess our working environment with the proper ergonomic evaluation tools, but we expect the best results.
That’s not going to work, you have to use appropriate ergonomic evaluation tools to identify the potential hazards or the risks that your workers are going to face and to improve your working environment as soon as possible for achieving your goal and getting the best results out of all your hard work and dedication.
The frequent exposure of your workers to the ergonomic risk factors leads to poor work practices, poor health profile, and no familiarity over time and ultimately to the musculoskeletal disorder.
Hence, you’re highly recommended to deploy any of the above discussed ergonomic evaluation tools that would help you out with identifying all the possible risks of your working environment before they occur and harm the productivity of your industry or business.
