What is NMI?
Neuromuscular incapacitation is a direct involuntary contraction of the muscles that disrupts neuro-muscular control, affecting the motor, sensory and nervous systems within the body.

-
Ambos have to remove those in sensitive areas which are?
face, eye, neck, bone structure, groin or breast of females.
-
To reduce cardiac risk:
- Target the back
- Avoid targetting the chest
- Avoid prolonged and repeated exposures
-
Common effects of NMI
- Subject can fall down
- Yell or scream
- Involuntary muscle contractions
- Subject may freeze in place
-
Electrical:
- High peak arcing voltage 50,000
- Only 0.0021 amps, less than an xmas tree bulb
- Follows path of least reduction
- The greater the spread the better effectiveness
-
Digital pulse control
- Digitally controls pulse rate
- -20c+50c
- 5 Second automated burst
- 19 pulses per second
-
Operation:
- Single trigger pull and release discharges a 5 second cycle
- Shift safety down to stop discharge
- Hold the trigger will continue to discharge until trigger is released
-
What does the cid display?
- Warranty
- Current time gmt
- Temp
- Software revision
- Displays battery as rough percentage, if below 20 percent dont take out
- System sleeps after 20 mins of being armed, turn off and on again to re arm.
- Takes 1.5 secs to start recording on taser cam.
-
What does the illumination button do?
swaps between laser only, laser and flashlight (NSWPF requirement) and stealth mode
-
Maintenece and care
- Avoid dropping
- Check battery
- Store with cam inserted
- Check expiration for cartritdges(5 years)
- Secure in holster
- Do not store in pockets without holster
- Avoid excess moisture
- If display has an E H or blank return to armoury
- If submerged return to armouty
- Mark on sticker if there is evidence needed off it.
- Be aware of seatbelt in car
- Check and clean camera, cartridges, probe ect ect
- Taser downloaded monthly
-
Cartridge for NSWPF
- XP 25
- 7.6 metres
- green door, black cartridge
- Live cartridge
- Training cartidges fire 6.4 metres and are blue with blue doors, can drive stun but probes dont conduct.
- Orange cartridges are complety inert
- Inspect make sure blast doors are attached, no cracks, locking tabs are not
- compressed, expiration date, they last for 5 years.
- Top probe is always hirizontal, bottom probe is angled down at 8 degrees.
- For every 2.1 of travel it spreads 0.3 metres.
- NSW police training probe is short while the operation probe is longer
- Wires are steel with insulated coating, can break easy, inadvertant
- contact can get you zapped
- Tell partner to watch wires
- Avoid crossing wires with other tasers
-
Hazardous practice
- Accidental discharge of taser
- Reckless pointing or aiming at another officer
- Failing to properly store and secure taser
- Convering the lens of tazercam
- Any action or inaction deemed hazardous by a taser review pannel.
-
Modes of use
- Draw and cover, drawn from holster and pointed at a subject.
- Drive stun, direct contact. If one probe makes contact you can complete the circuit with a drive stun. Leave cartridge on when drive stunning.
- Not to be used for pain compliance
-
Criteria to draw and cover
- Do not draw your taser, point of aim it unless you are likely justified to use it
- Continue to assess environment to see if justification for the taser still exists
- Ensure CEW is armed and pointing at subject so camera can record.
- Comply with all firearm safety procedures
-
Criteria to discharge
- Protect human life
- protect yourself or others where violent confrontation or violent resistance is occuring or imminenent
- Protect officers in danger of being overpowered or to protect themselves or another person from the risk of actual bodily harm
- Protection from animals
-
Cew
Conducted electrical weapons are designed to use propelled wires or direct contact to conduct electrical charge to primarily affect motor function and/or sensory nervous system.
-
One probe can arc
Through 2 cumulative inches of clothing or 1 inch of clothing per probe
-
If under 20 percent battery
Don't take out
-
If you do hazardous practice you will be remediated
-
A Taser should not be used in any mode:
- For any other investigative purpose.
- Near explosive materials, flammable liquids or gasses.
- Where there is a likelihood of significant secondary injuries (elevated positions)
- Punitively for the purposes of coercion or as a prod to make a person move
- Passive non compliance
- Refusing to move or offering little or no physical resistance
- Refusing to comply with police instructions
- Acting as a dead weight or requiring an officer to lift, pull, drag or push them in order to maintain control
- to rouse an unconscious, impaired or intoxicated person(s)
- to target known pre-existing injury areas of a subject
- Crowd control measure such as crowd dispersal.
- when the subject is holding a firearm.
- against a mental health patient solely to make them comply or submit to medication or treatment.
- Unless it is in the performance of the officers duties or at an approved weapons training day
-
Taser should not be used unless exceptional circumstances exist:
- Against a person who is handcuffed
- Against a female suspected on reasonable grounds of being pregnant.
- on an elderly or disabled person(s)
- on a child or person(s) of particularly small body mass
- against the occupant(s) of a vehicle or the operator of machinery.
- against a subject that is fleeing.
- drive stun for pain compliance.
- Using the Taser in a prolonged fashion (holding trigger down > 5 second)
-
After 3 cycles police must reconsider the effectiveness of Taser device as the most appropriate tactical option and must consider alternative Tactical Options to resolve the situation.
-
Subjects should be allowed time to comply with police instructions (as is reasonable in the circumstances) before discharging the CEW. All instructions should be clear, concise and reasonable
-
Optimum range: 2.1-4.5 metres
-
If Taser Cartridge is a “dud,” keep device aimed at target while placing the X26 on SAFE
-
Is the suspect reacting?
- Look AND listen when evaluating the effectiveness of a Taser application
- No reaction, no change in subject behaviour or loud arching of the CEW, could indicate poor or no connection, minimal probe spread, or low muscle mass contact
- Suggested tactical considerations:Reload and target a different area (depending on situation)Drive-stun with a cartridge in place
- Consider other force options & be prepared to transition
It is essential that the operator assess the situation then instruct the back up officer to restrain the subject during the cycle.
