Balcony safety is layered: the physical opening, access to the balcony and everyday supervision all matter. A barrier may be one part of a household plan, not a substitute for active adult supervision.
Review access and routines
Notice when balcony doors are open, what furniture can be moved near an edge and whether a child or pet can access the area unsupervised.
Assess the barrier and fixing points
Measure the opening and check the surfaces around it. Ask an installer to explain the proposed coverage, fixing approach and how the installation should be checked over time.
Keep supervision central
Use child-safe door habits and keep climbable objects away from edges. Select a solution based on an in-person assessment and follow the building management requirements.
