Understanding Physical Intervention in the Private Security Industry

In high-pressure environments such as nightclubs, hospitals, events, retail spaces, and transport hubs, you may be called upon to manage conflict and maintain order. One critical skill to have in your toolkit is physical intervention.

But what exactly is physical intervention, and when is it appropriate to use?

What Is Physical Intervention?

Physical intervention refers to the use of direct or indirect force, through bodily, physical, or mechanical means, to limit another person’s movement.

It is distinct from defensive physical skills, which are used purely to protect oneself from assault.

There are two broad types:

• Non-restrictive interventions (e.g., guiding someone away): These allow a person to move freely and make their own decisions.

• Restrictive interventions (e.g., holding or restraint): These limit movement and are used only when absolutely necessary.

  
  

When Is Physical Intervention Justified?

Physical intervention should always be a last resort. It may be justified only when:

• All other options have failed or are likely to fail.

• There is a need to protect life or prevent serious harm.

• It is not safe or practical to withdraw from the situation.

Inappropriate or excessive use of force can result in legal consequences, dismissal, or even criminal charges.

That's why we must understand the legal and professional implications of our actions.

Understanding the Law

In the UK, force can be used if it is:

• Reasonable in the circumstances (self-defence, protection of others, or to prevent crime).

• Necessary: meaning that the situation justified an intervention.

• Proportionate: not excessive in comparison to the threat faced.

• Used as a last resort: only after all other de-escalation methods have failed or are likely to fail.

These criteria form the legal test that courts may apply when judging an incident involving force.

Risk Awareness and Assessment

Physical intervention carries inherent risks, especially if not handled correctly. These include:

• Medical consequences (e.g., positional asphyxia, trauma, sudden death).

• Emotional harm to both staff and the individual restrained.

Things to Take in to Account

When we are conducting our dynamic risk assessment prior to any type of physical intervention we need to take various things in to account.

• Situational factors like environmental hazards or lack of support staff.

• Individual factors including things like age, size and weight.

• Nature of the Restraint including the method we use, the position we hold them in a the duration of the restraint.

• vulnerabilities, particularly among children, the elderly, or people with mental health challenges.

To this end we must constantly perform dynamic risk assessments before and during any intervention, using tools like the SECURE model to evaluate threats and adapt accordingly.

Special Considerations: Ground Restraints

Restraints on the ground, especially face down (prone) and face up (supine) are high risk and should be avoided unless absolutely necessary.

Risks include:

• Impaired breathing (leading to positional asphyxia).

• Increased potential for injury including breaks and dislocations.

• Difficulty in monitoring the person’s wellbeing.

If ground restraint does occur, the floor should be checked for broken glass or debry, a team leader should be allocated to talk to and de-escalate the situation and manage the team and the person should be brought to a seated position as quickly as possible.

If a medical emergency occurs during the physical intervention then the person should be put in to the recovery position and an ambulance should be called.

Good Practice During and After Intervention

To minimise harm:

• Always use the least forceful option.

• Communicate clearly throughout the intervention.

• Monitor the person's condition continuously.

• De-escalate and release the hold at the earliest safe opportunity.

Following an incident, staff must:

• Report fully and accurately, including behaviours, actions taken, and any injuries.

• Seek medical support for anyone harmed.

• Reflect and learn from the experience to improve future practice.

• Access support for themselves or others who may be affected emotionally or physically.

Keeping Skills Current

Training isn't a one-time event. Just like a driver who passes their test and then develops bad habits over time, to negate this we must refresh our physical intervention training regularly. This ensures we stay aligned with updated legislation, best practices, and employer policies.

Conclusion

Physical intervention is a serious responsibility, not a routine part of conflict management. Used correctly, it can protect people from harm and help defuse dangerous situations. Used improperly, it can escalate risk, cause injury, or lead to legal trouble.

For anyone working in the private security industry, understanding when and how to use physical intervention, and equally, when not to, is essential to staying safe, lawful, and professional.
