Anti-Ligature Lighting in Custodial Environments

Custodial environments such as prisons, police cells, and detention centres present a unique set of challenges. Individuals in these settings may be distressed or vulnerable, and it’s essential to eliminate any opportunity for self-harm or violence. Anti-ligature lighting (now more widely known as ligature resistant lighting) plays a vital role in creating safer spaces.

In custodial environments, selecting the correct specification is critical. To better understand the terminology and why the industry is shifting away from the term “anti-ligature”, explore our guide to ligature resistant lighting.

What Is Anti-Ligature Lighting?

Anti-ligature lighting (now more widely known as ligature resistant lighting) is designed to prevent the use of lighting fixtures as ligature points. This means eliminating sharp edges, gaps, and exposed fixings that could be used to fasten a cord or be broken off and weaponised.

Our Custodial lighting Range has been developed over many years working in collaboration with Prison Operators, Designers and Maintainers, ensuring full compliance with the Ministry of Justice’s technical standards.
