What is meant by anti-ligature?

First, let’s drop the “negative” prefix and define “ligature”. The word ligature describes a device for binding or tying tightly objects related site. Anti-ligature means preventing binding or tying.

These devices help prevent self-harm by vulnerable people, whether it is accidental or deliberate. In prisons, hospitals and youth institutions as well, they are commonly found. They not only include luminaires, they also include the interior design. This includes everything from the design of the space to all the items inside.

A room may be at risk for ligature when it has any point that can act as a connection to a cord, rope, shoelace or other materials used in suicide. The most common attachment points are door handles, hooks, and frames.

Three types of antiligature measure are available: fixed and load release antiligature device and weapons deterrents.

The products made to prevent ligatures being released due to excessive strain are made in such a way that they will release under any excess strain. These products can be made from two to three parts depending on which part gives when under strain or excess weight.

The fixed anti ligature product has a higher durability and is designed so that it cannot be used as a hanger. These products are designed with curved surfaces, tamper resistant entry points and they cannot be removed using self-made tool.

Weapon deterrents cannot be broken down into components or parts to be used for weapons.

Lights can save Lives

In mental hospitals and in prisons, the suicide rate is highest. Hanging is the UK’s second-most-popular method of suicide. 59% males and 45% females commit suicide by hanging. Around 800,000 suicidal acts occur each year in the world. That’s one suicide every forty seconds. Anti-ligature-classified products are one of the ways to prevent suicides in buildings where they are mounted.

Anti-ligature lights have to meet certain criteria in order to be suitable for this type of environment. Also, they must be effective in preventing self-harm. The luminaire must have a smooth surface with curved edges. The luminaires have to be robust and strong with a mechanical resistance rating of IK10 to withstand a force up to 20 joules. The luminaires have to be mounted securely on the wall or roof with no protruding edge, gaps or any other element that could allow for ligatures to be attached. The luminaires must not be openable or able to separate. Surfaces along walls or ceilings need to be covered in anti-picking mastic or concrete silicone.

The antiligature light’s main purpose is to give its users the right level of visual comfort. The right light temperature creates a relaxed environment that can reduce anxiety. BBL areas and daylight-focused rooms are great ways to improve people’s sleep and circadian cycles, which can both be beneficial for their mental and bodily health. Researchers found the correct light could reduce symptoms of patients suffering from manic depressive behavior.

The presence detection and minimum dimming will provide a safe environment in environments where people are more vulnerable. The energy-saving features and maintenance notifications ensure the reliability of any lighting scheme.

Lighting solutions can be custom-made to fit buildings with anti-ligature lighting. These include luminaires equipped with circular optics, or mounting options like recessed mounts on walls and ceilings, circular-lens ceiling-mounted fixtures, and recessed-wall lights. Smart lighting control systems can be used to regulate the light and color temperature throughout the entire day. Human Centric Lighting or Blue Blocked Light solutions can also help to achieve best results.
