Ligature / Anti ligature
The CQC define a ligature point as “anything which could be used to attach a cord, rope or other material for the purpose of hanging or strangulation. Ligature points include shower rails, coat hooks, pipes and radiators, bedsteads, window and door frames, ceiling fittings, handles, hinges and closures.” Anti-ligature refers to products or design that prevents a ligature from staying secure. The aim is to eliminate the possibility of someone attaching a wire or cord around a product, so denying the means for inflicting harm to themselves or others.

LRV (Light Reflectance Value)
Providing contrast between adjacent colours and materials helps people perceive their surroundings and environment more clearly. LRV measures the percentage of light a colour reflects and is measured on a scale ranging from zero (black) to 100 (white). When you deduct one LRV from another you have the LRV contrast rating. Manufacturers can confirm the LRV for individual products. Between adjacent materials, such as walls and floors, a minimum contrast rating of 30 points is recommended by The Building Regulations. Between adjacent floor finishes the contrast rating should not exceed 10 points as some may perceived this to be a change in level or an obstruction.
