Risk Classes are categories of anomalous entities ranked by their severity of an anomaly's effects on one individual person and the difficulty it is to recover from such effects. Notably, alongside Disruption Classes, these are new classifications applied to newer SCPs and certain older SCPs as part of the Anomaly Classification System (ACS). There are five main classes, in which many entities are under: Notice, Caution, Warning, Danger, and Critical.
The Locked Box Test is difficult to use with Disruption Classes, with three simple questions replacing this test to determine the Risk Class: how fast do people recover from the effects, how severe are the effects, and when are the effects noticed.
Classes[]
Notice[]

Emblem for the Notice classification.
Anomalies classified as Notice have low risk potential. Notice SCPs rarely have any effects on humans, with any being mild at its maximum. When in proximity of a Notice SCP, one wouldn't feel any effects, due to their non-existence or how mild they truly are.
Caution[]

Emblem for the Caution classification.
Anomalies classified as Caution have moderate risk potential. Some effects on humans are present, though these are typically mild to moderate, possibly being mildly dangerous. Anyone being affected by a Caution SCP may feel some of the effects from it.
Warning[]

Emblem for the Warning classification.
Anomalies classified as Warning have high risk potential. These typically possess mild to severe effects on humans, posing moderate danger to those nearby a Warning SCP.
Danger[]

Emblem for the Danger classification.
Anomalies classified as Danger have very high risk potential, with a high possibility of being affected by a Danger SCP. These effects are also typically deadly, ranging from major to extreme. Anybody in the presence of a Danger SCP is at a high risk.
Critical[]

Emblem for the Critical classification.
Anomalies classified as Critical have incalculable risk potential, as the effects of a Critical SCP will be instant and/or severe. Death is highly likely and expected from Critical SCPs, though it is not guaranteed if caught in the presence of one. The possibility of recovery from the effects of a Critical SCP is deemed impossible.
