- CYes, if force is reasonable and the person is trespassing or breaching venue rules✓

- BThere is no right to defend yourself once you are working in a door supervision role
- CA lawful right to use force to protect yourself or others from unlawful attack✓

What is 'duty of care' in the context of physical intervention?
- AOnly qualified medical staff owe any duty of care to the people at the licensed premises
- BA door supervisor owes no duty of any kind to the people they deal with during a shift
- CYour legal obligation to ensure reasonable safety and not cause unnecessary harm✓
- DThe duty exists only while the premises are actually open to the public for trading
Answer: Duty of care is your legal obligation to take reasonable steps to ensure the safety of those around you and not cause them unnecessary harm. This continues during and after physical intervention.
If a door supervisor uses excessive force during a removal, what could be the consequences?
- AOnly a company warning
- BCriminal charges (assault/GBH) and civil liability✓
- CThey were doing their job, so there are no consequences
- DLicence loss is not possible
Answer: Excessive force beyond what is reasonable can result in criminal assault or GBH charges, civil liability, licence revocation, and dismissal. The force must always be proportionate.
What should be the priority order when managing a violent person?
- ADe-escalation first, then physical intervention only if necessary✓
- BUse physical force immediately, before attempting to speak to the person
- CAlways fight back
- DIgnore them
Answer: De-escalation through calm communication is always the first approach. Physical intervention should only be considered as a last resort when de-escalation fails and there is genuine danger.
What does 'restraint' mean in physical intervention?

- BStriking a person hard enough to force them to do as they are told
- CUsing control techniques to prevent someone from causing harm✓

- AIt has no risks
- BIt's completely safe
- CRisk of injury, panic, or positional asphyxia if not properly trained✓
- DOnly emotional harm
Answer: Improper restraint can cause serious injury or death, particularly positional asphyxia (restricting breathing). This is why proper training and proportionate use are critical.

- BUnlawful in all circumstances
- CWhenever a customer is upset
- DOnly when necessary, proportionate, and to prevent harm or protect persons/property✓
Answer: Physical intervention is lawful only when it is necessary to prevent harm, protect persons or property, and the force used is proportionate to the threat. Any other use is assault.
What should a door supervisor do after using physical force against someone?
- ASimply move on without taking any further action
- BDocument the incident, ensure the person's safety, offer assistance, and report to police if needed✓
- CApologise to the person for what happened and then allow them straight back into the venue
- DKeep what happened between the staff who were involved and make no written record of it anywhere
Answer: After physical intervention, ensure the person's wellbeing, document what happened, report to management and police if appropriate, and provide first aid if needed. This protects everyone.
What is 'reasonable' force dependent on?
- AYour physical size
- BThe time of night
- CThe threat level, the person's behaviour, and available alternatives✓
- DYour experience level
Answer: Reasonableness depends on the actual threat (weapons, multiple attackers), the person's behaviour, your ability to de-escalate, and available alternatives. A proportionate response is tailored to the situation.
Can a door supervisor physically remove someone who refuses to leave voluntarily?

- BYes, if removal is lawful and force used is reasonable and proportionate✓
- CRemoval by force is unlawful in every case

- BProper training is essential before using any physical techniques✓
- CPhysical intervention training is only needed by serving police officers
- DAnyone working on a door may use physical techniques with no training at all

What should a door supervisor assess before using physical force?
- AOnly the size and physical build of the person they are dealing with at the time
- BJust the age of the person who has become involved in the incident at the door
- CInstinct alone; the supervisor should act straight away without assessing anything
- DThe threat level, available alternatives, risks, and proportionality✓
Answer: Before physical intervention, assess: Is the threat real? Are there alternatives (de-escalation, retreat, backup)? What injuries could result? Is the force proportionate? This assessment protects everyone.
What does 'risk assessment for physical intervention' mean?
- AAssuming that every person being dealt with has some underlying health condition of their own
- BSkipping the assessment altogether
- CAssessing how risky the customer looks
- DEvaluating whether physical intervention is safe given weapons, health issues, or environment✓
Answer: Risk assessment involves considering hidden weapons, medical conditions (pregnancy, heart disease), environmental hazards, and numbers. Some situations make physical intervention too risky.
What precaution should be taken if someone claims to have a weapon?
- ATreat it as a genuine threat, retreat, call police, and inform others✓
- BTry to take it from them
- CCarry on dealing with the situation in exactly the same way as before the claim
- DAssume that the person is bluffing and take no further action of any kind
Answer: Any claim of a weapon should be taken seriously. Retreat to a safe distance, call police immediately, keep others away, and wait for police response. Never attempt disarming.
Can a door supervisor legally prevent someone from leaving the venue against their will?
- AIt depends entirely on how old the person concerned happens to be
- BYes, if the person still owes money for their drinks or their entry
- CNo, unless they are being detained lawfully (e.g., by police)✓

- BWhat led to it, who was involved, what happened, injuries, witnesses, police notification✓
- CRecording is required only if the police later ask for a written statement

What is the difference between 'force' and 'assault'?
- ALawful force is different from unlawful assault✓
- BThere is no difference between the two terms in law
- COnly assault is illegal, because force is never unlawful
- DBoth are always illegal on licensed premises in the UK
Answer: Lawful force (reasonable, proportionate, necessary) is different from assault (unlawful force causing harm or threatening it). The same action can be lawful force or unlawful assault depending on circumstances.
What is 'GBH' (Grievous Bodily Harm)?
- AAny minor injury
- BOnly small cuts
- CVerbal harm
- DSerious injury causing long-term harm, such as broken bones or deep lacerations✓
Answer: GBH is serious bodily harm such as broken bones, significant scarring, or permanent injury. It is a serious criminal offence. Door supervisors must avoid causing GBH.

Can a door supervisor use physical force against someone who is not being violent?
- ANever under any circumstances, since any contact with a non-violent person is an assault
- BYes, if the customer is rude or argumentative towards staff, force may be used to move them on
- CYes, at any time, because door supervisors hold the same powers as a constable on licensed premises
- DOnly if necessary to prevent harm or enforce legal removal; force must be proportionate✓
Answer: Physical force can only be used if it is necessary (de-escalation failed), lawful (removing a trespasser), and proportionate (no more force than needed). Rudeness alone does not justify force.
What should a door supervisor do if they feel a situation is becoming too dangerous for physical intervention?
- ACall for backup, retreat to safety, let police handle it✓
- BTry harder
- CLeave without helping
- DContinue anyway
Answer: If a situation is too dangerous (multiple attackers, weapons, medical issues), retreat to a safe distance, call for backup and police, and do not attempt physical intervention.
What is 'positional asphyxia'?
- AA type of breathing exercise
- BDeath or serious injury from restricting someone's breathing during restraint✓
- CA condition that only ever affects athletes during periods of heavy physical exercise
- DA breathing technique
Answer: Positional asphyxia is when someone cannot breathe properly due to their body position during restraint, particularly face-down pressure on the chest. It can be fatal within minutes.
How can positional asphyxia be prevented during physical restraint?
- AApply the restraint more firmly and hold the position for longer until the person stops struggling completely
- BKeep restraint brief, avoid face-down positions, call ambulance if unresponsive, use trained personnel✓
- CPositional asphyxia is impossible to prevent
- DPositional asphyxia only affects people who are already unwell, so no special precautions are needed during a restraint
Answer: Prevention includes keeping restraint brief and only when necessary, avoiding prolonged face-down positions, monitoring breathing, calling emergency services if any distress, and using trained staff only.
What is the 'doctrine of necessity' in relation to using force?
- AOnly doctors use necessity doctrine
- BForce can be used when necessary to prevent imminent harm or crime✓
- CForce is never necessary
- DAny force is necessary
Answer: The doctrine of necessity allows use of force when it is necessary to prevent imminent harm or protect against crime. The force must still be proportionate and reasonable.
What is a 'proportionate response' in physical intervention?
- AAlways use maximum force
- BAvoiding force altogether, whatever the circumstances may be
- CUse only the force necessary to achieve the lawful aim✓

- BDeny it happened
- CSend the injured person an invoice for any damage that was caused to the venue
- DProvide first aid, call ambulance if needed, report to police and management✓
Answer: Immediately provide first aid, call emergency services for serious injuries, document the incident, notify police and management, and cooperate with investigations. Never hide or minimise injuries.
Can someone be charged criminally AND face civil liability for the same use of force?
- AOnly civil proceedings can ever follow from the use of force at work
- BYes, criminal and civil actions can be pursued separately✓
- CNo, only one type of legal action can ever be brought against a person
- DOnly criminal charges can ever follow from a use of force at a venue
Answer: A door supervisor can face criminal charges (assault/GBH) and separate civil claims (damages) for the same incident. These are independent legal processes.
What is the Criminal Law Act 1967 Section 3?
- AIt applies to violence only
- BIt allows use of reasonable force to prevent crime or protect persons/property✓
- CIt bans the use of violence of any kind on licensed premises in England and Wales
- DIt only applies to police

- AA door supervisor has no duty of care at all once the incident has ended
- BYou must provide reasonable care and call ambulance for serious injuries✓
- CCare is optional
- DOnly trained paramedics have any duty to help a person who has been injured

Should a door supervisor restrain someone who is having a medical episode?
- AYes, hold them down firmly on the floor until they become calm again and stop moving
- BOnly if the person refuses to leave the premises when they are asked to do so
- COnly if the person specifically asks to be held while they are recovering
- DNo, call ambulance and avoid physical contact unless absolutely necessary✓
Answer: Medical episodes require emergency services, not restraint. Restraining someone having a seizure, heart attack, or psychiatric crisis can cause serious harm. Call 999 and monitor breathing.
What is the 'minimum force principle'?
- AForce is never necessary
- BUse only the minimum force necessary to achieve a lawful aim✓
- CEveryone gets the same force
- DUse as much force as possible
Answer: The minimum force principle means using the least amount of force needed. A warning, then refusal of entry, then gentle removal is preferred to aggressive physical intervention.

- BYes, if force would be unlawful or disproportionate✓
- CAny refusal would itself breach the SIA Code of Conduct
