Triage matrix: crowd dispersal weapons and specific injury patterns

Understanding the physical mechanism of each crowd dispersal device allows first responders and bystanders to look for hidden internal injuries that are easy to miss in a chaotic street environment.

Weapon Category Common Examples & Mechanics Muzzle Velocity / Output Primary Trauma & Medical Risks Critical First Aid Rule
Projectiles de impact kinetique (KIP) 40 mm sponge rounds, foam baton rounds, rubber-coated metal bullets, wooden batons, and 12-gauge fabric "beanbag" rounds (filled with 40 grams of lead birdshot) 60 to 100+ meters/sec (200 to 330+ ft/sec); delivers heavy blunt impact energy (and penetrating trauma if fired under 10 to 15 meters / 33 to 50 feet) Head/Face: Globe rupture (permanent blindness), orbital fractures, depressed skull fractures, brain hemorrhage.
Torso: Kɔkili karilen, fogonfogon sɔgɔli, fogonfogon binna, sɔgɔsɔgɔninjɛ/sugunɛ karilen, commotio cordis.
Fɛn senw: Karilenw ni jiribolo minnu bɛ don a kɔnɔ
Treat close-range KIP hits to the head, neck, or torso as severe high-energy trauma (like a gunshot or baseball bat blow); never pull an embedded rubber or beanbag round out of a wound
Explosive Stun Grenades (Flashbangs) & Concussion Grenades Pyrotechnic canisters containing a magnesium/aluminum and ammonium/potassium perchlorate flash powder charge designed to burst through vent holes 170 to 185 decibels (dB) acoustic blast wave + 6,000,000 to 8,000,000 candela blinding flash + extreme heat (>1,500 C / 2,732 F) Primary Blast: Tulokisɛw karilen (tympanic membranes), senkɔniw ka mɛnni tiɲɛni banbali, kunsɛmɛ joginni min bɛ kɛ ni bɔnɛ ye.

Never pick up or kick a canister. Keep ruptured ears strictly dry; cool thermal burns with water for 20 minutes; treat shrapnel wounds with direct pressure
Pyrotechnic Tear Gas Canisters (CS / CN Smoke Grenades) Metal canisters that expel chemical irritant smoke by burning an internal pyrotechnic fuel block for 30 to 90 seconds Canister body heats to 400 to 600+ C (750 to 1,100+ F); heavy metal projectile if fired from a 37/40 mm launcher Severe contact burns if touched barehanded; direct canister impact causes fatal skull or facial fractures; dense smoke causes acute bronchospasm and asphyxiation in enclosed spaces Never touch a hot canister without thick welding-grade heat gloves; do not trap a smoking canister under a plastic bucket where gas pressure can rupture the container
Long-Range Acoustic Devices (LRADs / Sound Cannons) Directional acoustic hailers mounted on vehicles or tripods emitting focused high-frequency beams (2,000 to 4,000 Hz, where the human ear is most sensitive) 135 to 162 decibels (dB) at 1 meter (human pain threshold is 120-130 dB; instant mechanical inner-ear damage occurs at 140+ dB) Acute acoustic trauma, permanent cochlear hair-cell destruction, severe debilitating tinnitus, vestibular vertigo, nausea, loss of balance, and migraine Step laterally out of the narrow 15-to-30-degree directional cone immediately (moving to the side drops sound intensity by 20 to 30 dB); plug ears firmly with foam earplugs or fingers
Pepper Balls & Paintball Marker Rounds Pressurized plastic spheres filled with capsaicin (PAVA / OC) powder fired from compressed-air launchers 85 to 110 meters/sec (280 to 360 ft/sec) Direct eye impact causes immediate hyphema (bleeding inside the front of the eye), lens dislocation, or globe rupture, compounded by intense chemical capsaicin burning inside open skin welts Check for mechanical eye injury first before flushing; flush surrounding skin with cool water without rubbing capsaicin powder deeper into broken welts

Step 1: Treating Kinetic Impact Projectile (Rubber Bullet & Beanbag) injuries

A widespread myth is that "rubber bullets" are made of soft, bouncy rubber like a child's toy ball. In reality, many kinetic impact projectiles consist of a solid steel, lead, or aluminum core coated in a thin 2-millimeter layer of hard vulcanized rubber or dense polyurethane foam, while 12-gauge "beanbag" rounds consist of a Kevlar fabric pillow packed with 40 grams (1.4 ounces) of #9 lead birdshot fired from a shotgun at 70 to 90 meters per second (230 to 300 feet per second).

When fired from short range, or when a projectile ricochets off asphalt pavement and tumbles edge-on into a bystander, the concentrated kinetic energy slices straight through skin, shatters bone, and embeds the projectile (along with dirty fabric from the victim's clothing) deep inside muscle or body cavities.

1. Ocular trauma: when a projectile or pepper ball hits the eye

Medical reviews show that eye impacts from kinetic projectiles carry one of the highest rates of permanent disability in crowd dispersal settings, frequently rupturing the eyeball (open globe injury), detaching the retina, or filling the anterior chamber with blood (traumatic hyphema).

Immediate eye trauma protocol: - Recognize an Open Globe Injury: Look (without touching or pulling on the eyelids) for a teardrop-shaped or irregular pupil, blood pooling inside the colored iris (hyphema), dark jelly-like tissue protruding from the white of the eye, a flattened or collapsed appearance of the eyeball, or sudden loss of vision ("everything went black or red"). - Apply ZERO pressure to the eyeball: Never press a gauze pad against a struck eye, and never pour high-pressure water or homemade antacid mixtures into an eye that has suffered blunt impact. Pressing on a lacerated eyeball squeezes the vitreous humor out of the eye, causing irreversible blindness. - Construct an improvised rigid eye shield: If you do not have a military aluminum Fox Eye Shield, take a clean disposable paper or foam drinking cup, cut or tear the bottom half off so it is 4 centimeters (1.5 inches) tall, and tape the rim of the cup over the bony brow ridge above the eye and the bony cheekbone below the eye so nothing touches the eyelid or eyeball itself. - Cover the uninjured eye too (Bilateral Patching): Human eyes are neurologically yoked together (consensual conjugate eye movement): every time your good left eye darts around to look at paramedics or streetlights, your injured right eye moves identically inside its socket, grinding fractured orbital bone or tearing retinal tissue. Gently covering the good eye with gauze calms both eyes while you guide the person by the arm to an ambulance. - Position upright at 30 to 45 degrees: Keep the patient sitting upright (never lying flat and never bending their head down) and instruct them not to cough, blow their nose, or strain, which spikes intraocular pressure. See our detailed eye injuries first aid guide.

2. Head, neck, and facial impacts

A 40-millimeter foam baton or rubber bullet striking the forehead, temple, jaw, or neck delivers enough blunt force to fracture the skull, crush the larynx (voicebox), or dissect the carotid artery.

  • Airway first on neck hits: A projectile striking the front of the throat can fracture the thyroid or cricoid cartilage, causing rapid internal swelling that blocks the airway within 10 to 20 minutes. If someone struck in the neck develops a hoarse voice, difficulty swallowing saliva, noisy high-pitched breathing (stridor), or bubbling/crunching under the skin of the neck (subcutaneous emphysema), call emergency services immediately and keep them sitting upright leaning slightly forward.
  • Screen for Intracranial Bleeds: Anyone struck in the head who loses consciousness (even for 3 seconds), vomits, becomes confused, develops unequal pupils, has clear fluid or blood dripping from the nose or ears, or experiences a worsening headache requires immediate emergency room CT imaging. See our head injuries guide.

3. Chest and abdominal blunt trauma (and embedded projectiles)

  • Never pull out an embedded rubber bullet or beanbag round: At ranges under 15 meters (50 feet), 40-millimeter sponge rounds and 12-gauge lead-shot beanbags regularly punch right through the skin and lodge inside the chest wall, abdomen, or thigh. Treat an embedded projectile exactly like an impaled knife blade: pulling it out in the street can uncork a torn artery. Leave it in place, pack clean gauze around the edges to stabilize it, and transport to a trauma surgeon. (Note for ER doctors: 12-gauge beanbag rounds contain lead birdshot that can rupture open inside the wound, requiring X-ray confirmation that all lead pellets and fabric wadding are surgically removed.)
  • Watch for Delayed Internal Bleeding (Spleen, Liver, and Lung): A person struck in the lower ribs or stomach by a baton round often walks away thinking they only have a nasty purple bruise, only to collapse 2 hours later at home from a ruptured spleen, lacerated liver, or tension pneumothorax (collapsed lung). Seek urgent hospital evaluation after any torso impact if the person develops shortness of breath, sharp pain when taking a deep breath, pain radiating to the tip of the left shoulder (Kehr's sign of blood irritating the diaphragm from a ruptured spleen), pale clammy skin, dizziness when standing up, or a rigid, tender abdomen.

When an LRAD (Long-Range Acoustic Device) activates its high-pitched deterrent tone, it projects a tightly focused beam of 2,000-to-4,000-hertz sound energy at 135 to 162 decibels. Because decibels are measured on a logarithmic scale, every 10-decibel increase multiplies acoustic energy by 10-fold: 150 decibels is 1,000 times more intense than a 120-decibel rock concert or ambulance siren, causing immediate mechanical shearing of the delicate stereocilia hair cells inside the inner ear cochlea within seconds.

Ear Protection Method Holding flat palms loosely over the outside of your ears Press the fleshy tragus flap of each ear tightly into the ear canal opening with your index fingers (or insert NRR 32+ dB foam earplugs + over-ear earmuffs) Sealing the ear canal entrance tightly with the tragus or rolled foam earplugs cuts incoming sound pressure by 25 to 33 decibels, keeping inner-ear hair cells below the mechanical tearing threshold
Post-Exposure Care Returning to loud environments or wearing headphones that evening Total acoustic rest in a quiet room for 24 to 48 hours; see an ENT physician urgently within 24 to 72 hours if muffled hearing or loud ringing persists Early oral corticosteroid treatment prescribed by an ENT doctor within 48 to 72 hours of acute acoustic trauma can salvage stressed cochlear hair cells before permanent deafness sets in

Step 3: Safe decontamination of Tear Gas (CS) and Pepper Spray (OC) alongside wounds

When a person has both an open physical wound (such as a scrape, laceration, or ruptured eardrum) AND heavy chemical irritant contamination (CS tear gas or OC / PAVA pepper spray), your decontamination technique must avoid poisoning the open wound.

Decontamination Solution Safe for Intact Eyes & Skin? Safe if Person Has an Open Cut, Scrape, or Eye Injury? Scientific Evidence & Field Verdict

Cooking Oil, Petroleum Jelly, or Alcohol Wipes NO (Makes burns worse) NO CS tear gas powder and OC capsaicin resin are fat-soluble; oil-based lotions trap the chemical against the skin, while alcohol opens pores and causes severe pain

How to flush eyes and skin without spreading chemical crystals downward

  1. Do NOT rub your eyes: CS tear gas is not actually a gas; it is a fine aerosol cloud of microscopic solid crystalline particles (2-chlorobenzalmalononitrile) with tiny sharp edges. Rubbing your eyes grinds those crystals straight into your cornea, causing painful corneal abrasions.
  2. Stand into the wind and blink rapidly: Once out of the smoke cloud, face the clean breeze, hold your arms out from your sides, and blink rapidly so natural tears begin floating the particles out.
  3. Flush from the nose outward while leaning forward: Tilt your head forward and sideways (so contaminated wash water drips straight onto the ground rather than running down your neck, chest, and into your groin, where thin skin burns intensely). Pour a steady stream of clean cold water or sterile saline across the open eye starting at the inner corner next to the bridge of the nose and flowing outward across the temple for 5 to 10 minutes.
  4. Watch for severe Asthma or COPD bronchospasm: Inhaling CS tear gas or pepper spray triggers violent airway constriction in people with asthma or reactive airway disease. Help them sit upright in fresh air and assist them in using their prescribed albuterol / salbutamol rescue inhaler (2 to 4 puffs via spacer); if wheezing continues or lips turn blue, call emergency medical services immediately.
  5. Cold shower at home (before hot): When you get home, strip off your contaminated clothes inside a garage or bathroom into a sealed plastic bag. Step into a stone-cold shower for the first 5 minutes while leaning your head forward so water does not wash hair residue onto your lower body; taking a hot shower first opens skin pores and reactivates trapped CS crystals, causing a fresh full-body burning sensation.

When someone suffers severe bleeding, chest trauma, or airway distress during a public emergency, hands-on training makes all the difference. We strongly recommend taking an accredited Stop the Bleed course and a standard First Aid, CPR, and AED course from your national Red Cross or Red Crescent society, St John Ambulance, or local trauma center.

Can a "rubber bullet" or "beanbag round" really fracture a skull or kill someone?

Yes. Despite the casual name "rubber bullet," kinetic impact projectiles (KIPs) are heavy batons made of hard vulcanized rubber, dense polyurethane foam, or metal cores coated in rubber, fired from 37 mm or 40 mm launchers or 12-gauge shotguns at speeds of 60 to 100+ meters per second (135 to 225+ miles per hour). A systematic medical review published in the journal *BMJ Open* analyzing 1,984 people injured by kinetic impact projectiles found that 53 died from their injuries and 300 suffered permanent disability (most commonly permanent blindness from ruptured eyes, traumatic brain injuries from depressed skull fractures, and ruptured abdominal organs). Any hit to the head, neck, chest, or abdomen must be treated as a potentially life-threatening trauma emergency.

Why did the person I was helping tell me NOT to pour liquid antacid (Maalox) or milk into their eyes after a pepper ball hit them?

Because a pepper ball or close-range blast causes **mechanical corneal abrasions or open globe lacerations** on top of the chemical irritation. Pouring unsterile milk (which teems with bacteria once warm in a backpack) or chalky particulate liquid antacid (magnesium/aluminum hydroxide) into an eye that has a scratched cornea or ruptured eyeball introduces foreign particles and bacteria deep into the eye and can cause permanent blindness. In addition, a landmark randomized clinical trial published in the *Western Journal of Emergency Medicine* compared baby shampoo, milk, liquid antacid, lidocaine, and plain water for pepper spray decontamination and proved that **plain cold water / sterile saline works just as fast as every other substance** while being 100 percent sterile and safe for open wounds.

What should I do if a smoking tear gas canister or flashbang lands right at my feet?

Never bend down to pick it up with your bare hands, never kick it with a thin sneaker, and never trap it underneath a sealed plastic bucket or traffic cone. First, if the canister is a **flashbang / stun grenade** (which detonates 1.5 seconds after release) or an instantaneous blast tear-gas grenade, trying to grab or kick it can blow your hand or foot off at the wrist or ankle. Second, if it is a **pyrotechnic burning CS tear gas canister**, the metal shell burns at 400 to 600 degrees Celsius (750 to 1,100 degrees Fahrenheit), causing instant third-degree contact burns through ordinary gloves, and trapping a burning canister inside a tight container can cause pressure buildup and explosion. The safest action for any bystander is to **turn away, shield your eyes and ears, and move 15 meters (50 feet) laterally and upwind immediately**.

My ear has been ringing loudly and sounds muffled like I am underwater ever since a flashbang went off near me yesterday. Should I wait for it to clear up on its own?

Do not wait. Go to an urgent care clinic, emergency department, or Ear, Nose, and Throat (ENT / Otolaryngology) specialist within the **first 24 to 72 hours**. A flashbang blast wave (170 to 185 dB) can cause two distinct injuries: a physical hole torn in your eardrum (**tympanic membrane perforation**), which requires an otoscope check and strict dry-ear precautions to prevent infection, AND acute inner-ear hair-cell damage (**acute sensorineural acoustic trauma**). If you have suffered acute sensorineural hearing loss from a blast or LRAD, an ENT doctor can prescribe a short, high-dose burst of oral corticosteroids (such as prednisone) within the first 48 to 72 hours, which reduces inner-ear inflammation and significantly improves the chances of recovering your hearing before the damage becomes permanent.

Why should I never wear contact lenses if there is any chance of being caught near tear gas or pepper spray?

Soft contact lenses act like microscopic sponges that soak up and trap dissolved CS tear gas chemicals and oily OC capsaicin resin directly against your cornea. Even if you flush your eyes with a liter of saline, the chemical stays trapped underneath the contact lens, continuing to burn your cornea until it causes a severe corneal ulcer. Worse yet, trying to pinch a contact lens out of your eye in the street while your fingers are coated in tear gas crystals rubs the crystals straight into your eye. If you are ever exposed to tear gas while wearing contacts, have someone with clean, gloved (or thoroughly washed) hands help you remove and **permanently throw away** the contact lenses (soft lenses contaminated with CS or OC can never be cleaned and reused).

How do I wash tear gas (CS) powder out of my clothes and skin when I get home without re-gassing my whole bathroom?

CS tear gas is a fine solid crystal powder clinging to your hair, jacket, and pants. When you get home, strip off your outer clothes on an outdoor porch, balcony, or garage floor (never shake them out in your bedroom) and seal them in a plastic bag. Step into the shower and turn the water to **cold for the first 5 minutes** while leaning your head forward so hair runoff goes straight down the drain without running over your chest and groin (hot water opens your pores and vaporizes CS crystals into steam, gassing you all over again). After 5 minutes of cold rinsing, wash with mild soap and lukewarm water. Wash the contaminated clothes **separately from all other family laundry** using cold water and standard laundry detergent, and run them through two full rinse cycles before drying.
