25
What are the lethal target zones for baton strikes?
Head, Neck, Spine
26
What are the control principles used when striking preferred target zones with the baton?
Motor dysfunction, stunning, balance displacement
27
What are the 2 types of baton retention?
1) Holstered 2) Drawn
28
What is OC spray?
Oleoresin Capsicum, inflammatory agent that can give you a tactical advantage.
29
What is the minimum distance OC can be used at?
3 feet
30
What are the physiological effects of OC spray?
Respiratory, skin, eyes
31
Define positional asphyxia?
When the position of the body contributes to inadequate exchange of air.
32
What is ballistic needling?
When the OC particles become imbedded in the eye/ Cornea (Usually because it was within 3 feet)
33
what are the psychological effects of the OC Spray?
Focus on pain, anxiety, fear, panic, anger, goal reorientation, sense of helplessness, thought process interruption.
34
What are the advantages of OC spray?
You can engage at a greater distance, temporary effects, easy to use, can prevent physical altercation, can prevent escalation of force.
35
What are the disadvantages of OC?
It can cross contaminate, effected by wind and rain, threat can avoid the spray, may have eye protection, and can increase aggression.
36
When should you decontaminate the subject and how?
When tactically safe to do so. With cold clean water, remove contacts and contaminated clothing, verbal reassurance.
37
Define excited delirium?
A state of extreme mental and physiological excitement, characterized by agitation, hyperthermia, hostility, exceptional strength and endurance without apparent fatigue.
38
What are the characteristics of excited delirium?
Increased pain tolerance, tachypnea, sweating, agitation, hyperthermia, lack of tiring, unusual strength, inappropriately clothed, non - compliance.
39
How does excited delirium develop?
Police/EMS called, subject oblivious to police, multiple officers to control, become tranquil/calm, fatal cardiac/respiratory can follow.
40
what is the perfect storm for excited delirium?
Physical restraint, behaviour needing intervention and surge of fight or flight hormones.
41
What are some pre-contact strategies for excited delirium?
Keep distance, encourage talking, low lighting, calm/slow speech, slow movement.
42
what could be the best response if an individual is suspected of excited delirium (Intervention)?
Identify, control, sedate and transport
43
Define positional asphyxia?
When the body's position contributes to the restriction of adequate air exchange.
44
Objective reasonable test?
1 - Was the officer lawfully placed? 2 - Did the officer subjectively believed that the use of force was reasonable. 3 - would a reasonable person believe that the use of force used was reasonable.
45
What is the A.I.M Model?
Ability - able bodied intent - verbal or physical means - delivery system.
46
Use of force principle?
Public safety officer Safety continuous risk assessment best strategy
47
What are the officer response options?
- Officer presence - Perception and tactical considerations is officer based - communications - physical control - intermediate weapons - lethal force
48
What are the subject behaviour category?
cooperative passive resistor Active resistor assaultive grievous bodily harm/death
49
What are two types of neck restraint and the difference?
- respiratory and vascular. - Respiratory has a higher risk of serious injury or death and is applied to the trachea. - Vascular is safer by reducing blood flow to the brain using the sides of the neck.
50

5-30 seconds
53
What are the three level of compressions (Shoulder pin)?
1. Rear neck level, no compression 2. Mechanical compression until conscious compliance. 3. Compression until unconsciousness.
54
How many angles of attack are there when a knife is involved and how many defense zones?
5 Angles and 5 defense zones
55
What are the 5 common characteristics of edged weapon attacks?
1. Close range 2. typically not brandished 3. majority are right-handed 4. Off hand is used to gauge distance 5. It is repetitive
56
Knives have stopping power through?
1. psychological effect 2. pain 3. damage to major organ 4. blood loss 5. damage to the nervous system 6. structural damage
57
What is the triangle of death in edged weapon theory?
Small area just above collar of your vest located around the throat.
58
Legal authority for use of force?
CCC Section 25 - As much force as necessary to gain compliance CCC Section 26 - Excessive use of force CCC Section 27 - Authority to prevent a commission of crime/Offence.
59
Use of force impact factors?
- Subject: age, size, gender, number of subjects, training, history, flight risk, audience, weapons - Environment: weather, time of the day, encampment, isolated, on view, lighting, footing - Officer: age, training, subject knowledge, position, time and distance, equipment, position, injuries, number of officers, response time for back up.
60
7 Tactical principles?
Winning Mentality Cover and concealment Time: distance ratio One Plus One Rule Threat Cues De – escalation Verbal Commands
61
5 Areas of risk in use of force
Hands, Weapons, Friends and associates, escape route, Environment
62
Reactionary gap? Two types?
6 Feet, Inside Gap - Less than 6 feet - Outside Gap - More than 6 feet
63
Handcuffing - D.SALPS
- Double lock - search - Ask - Look - Pat - Squeeze
64
Tactical consideration in handcuffing is based around three concepts?
- Approach to contact - Control upon first touch - Speed of application
65
Types of subjects - Handcuffing theory
- Totally cooperative - Potentially uncooperative – most dangerous to handcuff. - Totally uncooperative
66
What circumstances would it be reasonable to handcuff a subject?
- Committed a crime - Escape risk - Safety hazard
