Clarification on the use of vascular restraint
There have been several recent incidents involving door supervisors that have resulted in serious injury, or worse, to members of the public. In some cases, these injuries have been attributed to the use of so-called ‘vascular restraints’. These are also known as ‘chokeholds’, and are extremely dangerous.
These techniques are not part of SIA required training for licensed operatives, and should not be used. There appears to be a belief among some operatives that these are legitimate restraints, mandated for use by law enforcement agencies. Please be aware that the use of neck restraints by police officers both here and in the United States has been prohibited for almost 30 years.
For best practice SIA recommend that security operatives should only use the techniques that they have been trained to use as part of their SIA-linked training on physical intervention.
