Why are there so many BDSM safety models?
“Why Are There So Many BDSM Safety Models??” was written for BDSMforyou.nl by Mistress Moriah.
Anyone who delves into BDSM will sooner or later come across a whole range of terms that all seem to say something about safety, consent, and responsibility. SSC, RACK, PRICK, FRIES and even newer variations such as SSICK. For many beginners, this raises questions. Why do so many different models exist side by side? Do they contradict each other? And which model is actually the best?
The answer is both simple and complex. All these models arose from the same need: to create a common language for discussing safety, consent, and risks within BDSM. As the community evolved and new insights emerged, so did the need for models that better aligned with real-world practice. As a result, various approaches have emerged over the years, each with its own emphasis, while at their core they share a striking number of similarities.

SSC: the foundation upon which much has been built
The best-known model is undoubtedly SSC, which stands for Safe, Sane, and Consensual. Loosely translated, this means that a BDSM experience takes place safely, sensibly, and with mutual consent. When SSC gained popularity in the last century, it played an important role in establishing BDSM as something fundamentally different from mistreatment or abuse. The model made it clear that BDSM revolves around voluntariness and consciously chosen interactions between adults.
However, over time, SSC also came under criticism. The term “safe” suggests that risks can be completely ruled out, whereas every experienced BDSM practitioner knows this is not realistic. Even relatively simple forms of play, such as spanking, bondage, or wax play, carry certain risks. As a result, the question was increasingly raised as to whether BDSM can truly ever be completely safe. That discussion formed the basis for the development of new models.
RACK: Recognizing That Risks Exist
One of the best-known successors to SSC is RACK, which stands for Risk-Aware Consensual Kink. This model is based on a different premise. Instead of asserting that BDSM must be safe, RACK acknowledges that certain risks are inherent in many BDSM activities. The focus thus shifts from eliminating risks to understanding and managing them.
Many experienced BDSM practitioners feel at home with this approach because they know from experience that zero risk simply does not exist. Just as with mountain climbing, horseback riding, or motorsports, risks can be reduced through knowledge, preparation, and experience, but they can never be completely eliminated. RACK therefore places more emphasis on awareness and informed choices than on the pursuit of absolute safety.
PRICK: Focus on Personal Responsibility
Based on the same philosophy, PRICK – which stands for Personal Responsibility Informed Consensual Kink – was later developed. While RACK primarily emphasizes risk awareness, PRICK explicitly shifts the focus to personal responsibility. Within this model, it is assumed that each participant actively takes responsibility for their own choices.
This means not only that someone gives consent, but also that that consent is based on sufficient knowledge of the possible consequences. After all, if someone agrees to something without understanding the risks, it is difficult to speak of a fully informed choice. PRICK therefore emphasizes that knowledge and responsibility go hand in hand.
FRIES and the Deepening of Consent
While SSC, RACK, and PRICK focus largely on safety and risks, FRIES focuses on consent. The model describes the conditions that valid consent must meet. Consent must be given freely, be revocable at any time, be based on sufficient information, be given enthusiastically, and relate to a specific act or situation.
The popularity of FRIES demonstrates how significantly thinking about consent has evolved in recent years. Whereas consent used to be reduced to a simple yes-or-no question, there is now much greater attention paid to the circumstances in which consent is given. As a result, there is also a growing awareness that consent given under pressure, out of fear, or due to emotional dependence takes on a completely different meaning.
Why do new models keep emerging?
The reason new terms keep emerging has mainly to do with evolving understanding. BDSM is not a static concept. Knowledge about psychology, trauma, communication, and power dynamics is constantly growing. As a result, the focus within the community is also shifting. Whereas the discussion used to center primarily on physical safety, there is now much more attention paid to mental safety, emotional harm, and the influence of manipulation or peer pressure.
New models are often an attempt to incorporate these additional insights into existing safety frameworks. Sometimes this yields truly new perspectives, while other models are primarily a different formulation of principles that have existed for some time.
What does it ultimately come down to?
Despite all the acronyms and theoretical models, virtually every serious discussion about BDSM safety ultimately boils down to the same core values. It’s about consent, clear communication, sufficient knowledge, mutual respect, and the ability to take responsibility for the consequences of your choices. These principles form the common thread that runs through virtually all models.
That’s why, in practice, it’s often less important which model someone follows than how they actually behave. A Dominant who continues to learn, critically examines their own actions, and takes their partner’s safety seriously will generally act more safely than someone who knows all the acronyms by heart but doesn’t feel responsible for their behavior.
Perhaps that is ultimately the most important conclusion. The various models are valuable tools for having conversations about safety and consent, but no model can replace common sense, empathy, and responsibility. BDSM safety doesn’t start with an acronym. It starts with people who are willing to treat each other with care, communicate openly, and take each other seriously.
