Anti-ligature Ventilation Grilles
Ventilation Grilles are often positioned on ceilings or high on walls. Their openings can be used to create a ligature point, making vent grilles a serious hazard in mental health environments. Plastic grilles can be broken to create sharp instruments, creating a risk to service users and staff. Contour’s Anti-ligature Ventilation Grilles reduce the ligature risk when installed over the top of standard Ventilation Grilles.
