🏗️ WISHA Lifting Calculator – Quick Risk Analysis in Manual Material Handling Operations
The WISHA Lifting Calculator is a practical and user-friendly tool designed to quickly and effectively assess ergonomic risks in manual material handling processes. In collaboration with Tokgöz Ergonomics, this calculator is used as part of a comprehensive solution to create safe working environments, reduce MSD risks, and develop sustainable ergonomic solutions.
1️⃣ Function and Application of the WISHA Lifting Calculator
WISHA is ideal for businesses that want to perform quick risk assessments, especially in manual lifting and lowering tasks:
Simple Risk Assessment:
It practically identifies risks in the operation without the need for complex mathematical calculations.
Form-Based Analysis:
The worker's posture, the duration of this posture, and the activity performed are analyzed by marking them on a form.
This approach provides quick results based on field observation and time tracking.
Speed and Accessibility:
Easily applicable by trained or untrained field personnel.
2️⃣ Broad Context within Lifting and Carrying Analyses
WISHA is a key component of Tokgöz Ergonomics' comprehensive set of lifting and carrying analyses:
Complementarity with NIOSH:
While WISHA provides a simple preliminary assessment, the NIOSH Revised Lifting Equation provides scientific precision with RWL and LI values.
Population and Gender-Focused Analysis:
Snook-Liberty Mutual Tables assess workload according to population percentage, offering threshold values specifically for female employee safety.
Occupational Disease and Risk Monitoring:
MAC Tool analyzes musculoskeletal disorders (MSDs) caused by manual handling operations, while the KIM-LHC method provides key indicator scoring for loads of 3 kg and above.
Pushing and Pulling Tasks:
Handling is not just about lifting. Using the RAPP Tool and KIM-PP, the risks of pushing and pulling wheeled equipment are assessed, completing the areas not covered by WISHA.
3️⃣ Training Content and Strategic Outcomes
Tokgöz Ergonomics' WISHA training aims not only to measure but also to develop a management strategy:
Compliance with Legal Regulations and Standards:
It offers an analysis and improvement process fully compliant with ISO 11228-1/2/3 and Law No. 6331.
Practical Competence:
Participants gain practical skills through field measurements and case analyses.
Sustainable Improvement Plans:
Risks identified by WISHA and other methods are supported by ergonomic engineering solutions, administrative controls, and cost analyses.
Preventive Approach:
Musculoskeletal disorders are predicted and prevented before they occur, thereby increasing work efficiency.
✅ What do you gain with the WISHA Lifting Calculator?
Fast and practical field pre-assessment
Early detection of MSD risks
Improved workforce safety and employee health
Holistic ergonomics management with methods such as NIOSH, Snook-Liberty, and KIM
Increased productivity and sustainable workplace safety
💡 Conclusion
The WISHA Lifting Calculator is a fast, reliable, and field-oriented tool that aligns with Tokgöz Ergonomics' philosophy of "the best posture is the next posture." Integrated with other analysis methods, it creates sustainable ergonomic solutions in the workplace that comply with legal regulations.
