SIA – Safer Physical Intervention for Door Supervisors

SIA – Safer Physical Intervention for Door Supervisors

The SIA has included a clarification, within the September SIA Update, on the use of safe physical restraints. To support this, we are sharing the 'Safer Physical Intervention for Door Supervisors' guidance.

This highlights the best practice physical intervention skills required of SIA licence holders.

It is crucial that you keep your physical intervention knowledge and skills current, for two principal reasons:

  • Legislation and guidance around physical intervention can change
  • Your proficiency in physical skills, if not practised, will decrease over time. This could reduce your ability to intervene appropriately and effectively, and increase the risks to you and others.

Door Supervisor training, and refresher training, is available through our training partner, Blueprint Training Solutions.

If you are a current staff member, this can be arranged through your line manager.


Please note:

Physical intervention must always be a last resort, used only by licensed SIA professionals who have undertaken the appropriate training.

In situations where physical intervention is necessary, the least forceful intervention practicable must be used.


Safer Physical Intervention

Even with high-quality SIA training, all SGL security personnel are trained to understand that there are always risks associated with using physical intervention.

It is important to avoid applying force or pressure to the neck, spine, vital organs, or vulnerable parts of the body as this approach can result in serious injury or even death.

Illegitimate physical intervention holds, particularly vascular restraints (choke-holds), are strictly prohibited and extremely dangerous. These techniques are not part of SIA required training for licensed operatives, and should not be used.

For best practice, the SIA recommends that security operatives only use the techniques that they have been trained to use as part of their SIA-linked training on physical intervention.

You should only ever use physical intervention as a last resort.

Examples of a 'last resort' situation include:
  • Where necessary to prevent harm
  • When other options have failed, or are likely to fail
  • When it is not possible or appropriate to withdraw

Alternatives to Physical Intervention

Primary Controls

  • Following employer safety and security policy, procedures and working practices
  • Use of safety and security equipment and technology (e.g. radio for summoning assistance, CCTV, access control)
  • Being positive and proactive in service delivery

Secondary Controls

  • Positive and effective interpersonal communication and the knowledge and skills of conflict management to de-escalate conflict situations and reduce the need for physical intervention

During Physical Intervention: Your Responsibilities

All staff involved in a physical intervention have a responsibility to ensure the safety of everyone involved. Where more than one member of staff is involved in a physical intervention, one of them should take charge of the intervention.

Use the least forceful option, and always challenge any unnecessary and excessive use of force by colleagues.

Maintain duty of care to the subject following restraint, and respect the dignity of people being restrained wherever possible.

Following Physical Intervention: Your Responsibilities

De-escalate a restraint at the earliest opportunity.

If the emergency services are present, describe in detail the circumstances, position, duration and any difficulties experienced in a restraint event.

Staff involved must fully report and account individually for their actions – ensure that you preserve evidence and secure witnesses to any restraint event.

Reducing the Risks of Physical Intervention

  • Choose the least forceful intervention practicable: The physical intervention with the least force and potential to cause injury to the subject in achieving the legitimate objective
  • Avoid high risk positions including ground restraints
  • Avoid high risk methods of restraint, such as neck holds and other holds that can adversely affect breathing or circulation
  • Keep up communication between staff and the subject during and following restraint
  • Monitor the wellbeing of the subject of intervention for adverse reactions
  • Ensure that leadership and teamwork happens, including the importance of someone taking a lead role and for others to support as team members
  • Ensure practice follows the procedures taught
  • De-escalate physical intervention at the earliest opportunity
  • Follow emergency procedures: Immediately release and assist subject if he or she complains of, or demonstrates signs of, breathlessness or other adverse reactions
  • Record and report restraints in line with employer and venue procedures
