Noise Measurements
Add areas, then add multiple readings per area. The app auto-averages.
✓ < 82 dB(A) | ⚠ 82–85 dB(A) | ✗ ≥ 85 dB(A)
Illumination Measurements
Add areas with lux readings. The app auto-checks against task-specific minimums.
✓ Meets minimum | ✗ Below minimum
Indoor Air Quality
Record ambient first, then each indoor area. 4 parameters per location.
Ergonomics Assessment
Add each workstation or area. Tick risk factors, set risk score, add photos and notes.
RF1–RF8: Office workstation risks
RF9–RF12: Manual handling & posture
CF1–CF4: Cognitive & psychosocial risks
H&S: General health & safety observations
