What catches people out.
- Intervals depend on the type of use and the fire-safety (SCIE) risk category of the building.
- Periodic lift inspections are requested through the municipality (Câmara Municipal).
- Some intervals (fire detection, emergency lighting, pressure equipment, electrical installations) are not listed here because we could not confirm them from official sources.
