Anti-ligature refers to design features or modifications specifically implemented to prevent or minimise the risk of ligature attachment, which is a potential method of self-harm. These features are crucial in settings such as mental health facilities and correctional institutions, where the safety and well-being of individuals are of utmost concern. By incorporating anti-ligature elements like rounded edges, ligature-resistant fixtures, concealed fittings, and anti-grip surfaces, the risk of individuals using ligatures to harm themselves is significantly reduced. It is important because these design measures help create safer environments, protect vulnerable individuals, and support their recovery by minimising the opportunities for self-harm.
CRR, or Crocodile Roll Resistant, refers to features or products designed to prevent or resist the dangerous self-harming behaviour known as a "crocodile roll." This behavior involves attempted self-strangulation or ligature attachment by twisting or rolling the body using a ligature. In settings like mental health or correctional facilities, specific design elements such as rounded edges, concealed fittings, ligature-resistant mechanisms, and anti-grip surfaces are incorporated to discourage ligature attachment and enhance safety.
