Traditional ergonomic assessments have always required trained specialists, paper forms, stopwatches, angle measuring tools, and hours of data entry after the fact. The process was slow, expensive, and inaccessible to most small and mid-sized workplaces that couldn't afford a dedicated ergonomist.
Today, with AI-powered mobile apps like Ergzo, any safety officer, HR manager, or occupational health professional can conduct a complete, scientifically valid ergonomic risk assessment using nothing more than the smartphone already in their pocket. Here is exactly how to do it.
Before You Start: What You Need
- A smartphone (iOS or Android) with the Ergzo app installed
- Access to the worksite or workstation you want to assess
- Brief verbal consent from the worker being observed
- A clear line of sight to the worker performing their task
Step-by-Step: Running Your First Assessment
Choose the right assessment tool for the task
Open Ergzo and tap "New Assessment." You will be asked to select an assessment tool. If the worker performs whole-body physical tasks like lifting, carrying, or bending — choose REBA. If the work is primarily upper-limb repetitive work like assembly, data entry, or sewing — choose RULA. For office workstation evaluations, choose ROSA. For manual lifting tasks with known load weights, use NIOSH.
Capture the posture — live camera or gallery upload
You have two options. For live assessment, point your phone camera at the worker while they perform the task — Ergzo's AI will automatically detect body landmarks and track joint angles in real time. For gallery upload, use any existing photo or video of the worker and upload it directly into the app. The AI processes it automatically. A side-view or 45-degree angle typically gives the most accurate results.
Answer the supplementary questions
After posture detection, Ergzo will ask a few short follow-up questions specific to your chosen tool — such as load weight (for REBA/NIOSH), task duration and frequency (for RULA/OCRA), or grip type and coupling quality. These take under 2 minutes and significantly improve the accuracy of the final risk score.
Review your risk score and body part breakdown
Ergzo instantly generates a colour-coded risk score: Green (Low), Orange (Medium), Red (High), or Dark Red (Very High). A body map diagram highlights exactly which joints and body segments are at risk — neck, shoulder, elbow, wrist, trunk, or lower back — so you know precisely where to intervene.
Review recommendations and build an action plan
For every high-risk body part, Ergzo provides specific, actionable recommendations — adjusting workstation height, introducing tool modifications, scheduling micro-breaks, or redesigning the task sequence. The app also auto-generates a corrective action plan that can be assigned to a supervisor or shared with management directly.
Export and share your report
Tap "Export" to download a professionally formatted PDF report with the worker's name, task details, posture images, risk scores, body part breakdown, recommendations, and the action plan. You can also export raw data in CSV or Excel format for record-keeping, insurance documentation, or compliance audits.
Tips for High-Quality Assessments
Camera angle matters
For the most accurate AI pose detection, position yourself at a 90-degree side angle to the worker (directly to their left or right). This gives Ergzo the clearest view of trunk angle, arm elevation, and knee bend — the three most critical measurements in most assessment tools.
Assess multiple tasks, not just one
Most workers perform several different tasks in a single shift. A warehouse worker might lift boxes (REBA), operate a forklift (ROSA), and do repetitive packing (RULA). Assess each task separately — Ergzo organises all sessions under the same worker profile so you can track cumulative risk across their full work day.
Reassess after interventions
The most powerful use of Ergzo is measuring whether your ergonomic improvements actually worked. After implementing a change — a new anti-fatigue mat, a height-adjustable workstation, a modified lifting technique — reassess the same task. Ergzo automatically calculates the before-and-after risk score difference so you can quantify the impact and present data-backed results to management.
Which Tool Should You Use for Which Industry?
How Long Does an Assessment Take?
A complete Ergzo assessment — from opening the app to downloading the PDF report — takes between 4 and 8 minutes per task. Compare this to traditional paper-based REBA/RULA assessments which typically take 20–45 minutes including data entry, scoring calculation, and report writing. Ergzo reduces assessment time by over 80%, making it practical to assess every worker at every workstation rather than just a sample.
