Positional Asphyxia in Security: Risks, Prevention, and Best Practices
SIA Refresher Training
In the security industry, physical intervention is sometimes necessary to manage aggressive or non-compliant individuals. However, improper restraint techniques can lead to serious consequences, including positional asphyxia—a condition that can be fatal. Understanding the risks, warning signs, and prevention methods of positional asphyxia is crucial for security professionals to ensure safety for both themselves and the individuals they handle.
What is Positional Asphyxia?
London Security College is a leading training provider offering a wide range of security, construction, and professional development courses. Their programs cater to both beginners and experienced professionals looking to upgrade their skills or renew their licences.

Positional asphyxia occurs when an individual’s body position restricts their ability to breathe properly. This often happens when excessive force is applied to the chest, neck, or abdomen, or when someone is restrained in a way that prevents normal breathing. In security settings, this can occur during detainment, physical intervention, or restraint techniques used to control aggressive individuals.
Causes of Positional Asphyxia in Security
Several factors can contribute to positional asphyxia, including:
- Restraining a Person in a Face-Down Position – Holding someone in a prone (face-down) position can limit their ability to expand their chest and breathe properly.
- Pressure on the Chest or Neck – Applying force on a person’s back, neck, or chest can compress the airway and lungs, making it difficult to breathe.
- Obesity or Pre-Existing Medical Conditions – Individuals with obesity, asthma, or heart conditions are more susceptible to breathing restrictions during restraint.
- Extended Duration of Restraint – Keeping an individual in a restricted position for a prolonged period increases the risk of suffocation.
- Excited Delirium – This condition, often linked to drug use or mental health disorders, can make individuals highly agitated and vulnerable to asphyxia when restrained.
Warning Signs of Positional Asphyxia
Security personnel must recognize the warning signs of positional asphyxia to prevent fatalities. Common indicators include:
- Struggling to breathe or gasping for air
- Gurgling or choking sounds
- Bluish skin (cyanosis), particularly around lips and fingertips
- Sudden unresponsiveness
- Loss of consciousness
If any of these signs are observed, security personnel must immediately release the individual from the restraint and seek medical assistance.
Preventing Positional Asphyxia in Security Operations
To minimize the risks associated with positional asphyxia, security professionals should follow these best practices:
1. Use Restraint as a Last Resort
- De-escalation techniques should always be the first approach before using physical intervention.
- Communication, negotiation, and maintaining a calm demeanor can prevent situations from escalating.
2. Avoid Prone Restraint
- Never restrain a person face-down unless absolutely necessary and for the shortest possible time.
- If a prone position is used, continuously monitor the individual and reposition them as soon as possible.
3. Minimize Pressure on the Chest and Neck
- Avoid placing weight on the back, chest, or neck of a restrained individual.
- Train security teams to use safer restraint techniques that do not compromise breathing.
4. Monitor the Individual Constantly
- Watch for signs of distress, breathing difficulties, or unconsciousness.
- Check the individual’s responsiveness regularly and adjust their position if needed.
5. Provide Immediate Medical Assistance if Needed
- If an individual exhibits signs of breathing difficulty, release them from restraint and call emergency services immediately.
- Ensure all security personnel are trained in emergency first aid and CPR.
The Role of Security Training in Preventing Positional Asphyxia
Security professionals must undergo proper training to ensure they understand the risks and prevention techniques associated with positional asphyxia. Training programs should include:
- Conflict Management & De-escalation Skills – Reducing the need for physical restraint.
- Safe Restraint Techniques – Learning to control individuals without compromising their ability to breathe.
- First Aid & Emergency Response – Recognizing the signs of medical distress and providing appropriate intervention.
- Legal & Ethical Considerations – Understanding the laws governing the use of force and the duty of care owed to individuals in custody.
Legal Implications of Positional Asphyxia
Security personnel must understand that improper restraint leading to injury or death can result in legal consequences, including:
- Criminal charges such as manslaughter if negligence is proven.
- Civil lawsuits from victims or their families.
- Revocation of SIA (Security Industry Authority) licences for failing to follow proper protocols.
Security firms must implement strict use-of-force policies and ensure all staff are trained in safe intervention techniques.
Conclusion
Positional asphyxia is a preventable but potentially fatal risk in the security industry. Security professionals must prioritize safety, awareness, and training to avoid dangerous restraint techniques and ensure compliance with best practices. By focusing on de-escalation, monitoring individuals in custody, and seeking immediate medical help when needed, security personnel can reduce the risks associated with positional asphyxia and protect both themselves and the individuals they manage.
Security is not just about control—it’s about responsibility. Proper training and awareness can save lives.
