2. ** Kuraho ifu ya chimique yumye MBERE YO kongeramo amazi **: Niba uwagabye igitero yateye ** ifu yumye ** (nka lime yumye, granules ya lye, cyangwa umukungugu wa sima) aho gukoresha amazi, koresha igitambaro cyumye, ishati yimyenda, cyangwa ikiganza cya kashe kugirango uhanagure ifu yumye yose kuruhu n imyenda * mbere yo gusuka amazi, kuko amazi make atera ubushyuhe bwumye cyangwa lye exothermic ubushyuhe. Bimaze guhanagurwa (cyangwa niba bimaze kuba amazi), jya guhita ugana amazi menshi.
3. FLUSH the eyes and face immediately with massive amounts of clean water for at least 20 to 60 minutes: Do not wait for paramedics to start washing. Pour bottled water, tap water from a sink faucet, a shower head, a garden hose, or even clean cold tea/saline (never milk or soda if clean water is reachable, and never delay to look for a "neutralizer") continuously over the burned face and skin. Every 30 seconds of delay allows alkali or acid to penetrate the cornea of the eye.
4. REMOVE all contaminated clothing, shoes, watches, and jewelry while flushing (Cut shirts off, do NOT pull over the head): Corrosive liquid soaked into a cotton shirt or collar acts as a toxic sponge that keeps burning the chest and neck. Using scissors, a knife, or tearing at the seams, cut the victim's shirt, bra, and trousers off rather than pulling a chemical-soaked T-shirt upward over their face and eyes. Rescuers must protect their own hands using nitrile gloves, plastic bags, or a dry cloth so they do not burn their own fingers.
5. Hold the eyelids wide open with your fingers and flush from the inner corner (nose side) outward: A person with acid or alkali in their eyes suffers intense involuntary eyelid spasm (blepharospasm) that squeezes the eyelids shut, trapping the corrosive liquid against the eyeball. Use your thumb and index finger to gently hold the upper and lower eyelids open, tilt the victim's head so the injured eye is lower than the uninjured eye (so chemical runoff does not wash across the bridge of the nose into the good eye), and pour water continuously from the inner nasal corner outward toward the ear.
6. NEVER apply creams, butter, oils, toothpaste, or baking soda/vinegar to a chemical burn: Never try to "neutralize" an acid with baking soda or an alkali with vinegar on human skin; acid-base neutralization reactions are exothermic (they generate intense heat) that adds a severe thermal burn on top of the chemical burn. Use only continuous, cool running water until paramedics take over.

Acids vs. Alkalis vs. Noxious Irritants: How street chemical attacks work¶

Perpetrators of corrosive attacks use four main classes of household or industrial chemicals. While the immediate first-aid treatment for all corrosive liquids is identical (immediate, massive water drenching), recognizing the physical signs helps you report critical details to incoming paramedics and poison control centers.

The 3-Step "REMOVE, REMOVE, FLUSH" Bystander Rescue Protocol¶

If you witness a corrosive liquid attack on a sidewalk, train platform, or parking lot, you do not need a medical kit to save the victim's eyesight and face. What you do in the first 45 seconds with a water bottle or shop sink is more powerful than any surgery a plastic surgeon can perform later.

Step 1: Protect Yourself While Approaching (Zero Secondary Casualties)¶

1. Check that the assailant has fled: Do not run into the path of an armed attacker holding an open bottle. Wait until the assailant rides or runs away, or pull the victim inside a shop door and lock it behind you.
2. Avoid bare-handed contact with puddles of concentrated acid:
3. Do not kneel with bare knees in puddles of liquid on the pavement, and do not wipe the victim's face with your bare palm.
4. If you do not have medical nitrile gloves in your pocket, slip two clean plastic grocery bags, dog-waste bags, or dry dish towels over your hands before touching the victim's wet shirt.
5. Stand slightly upwind if visible chemical vapor or fumes are rising from the victim's clothing.

Step 2: Source Massive Volumes of Clean Water Immediately (The "Bottled Water → Tap/Hose" Bridge)¶

• Seconds 0 to 30 (The Bottled Water Bridge): Shout to every pedestrian, cyclist, and shopkeeper within earshot: "ACID ATTACK. BRING EVERY BOTTLE OF WATER YOU HAVE RIGHT NOW." Even a 500-milliliter (16-ounce) bottle of drinking water poured immediately over the victim's open eyes and face in the first 15 seconds dilutes the acid concentration by 90 percent while you walk the victim to a faucet.
• Seconds 30 to Minute 30 (The Running Tap, Shower, or Hose): Guide the victim immediately to the nearest running water source:
• A restaurant kitchen sink with a pull-down sprayer hose.
• A hair salon shampoo sink (ideal for tilting the head back and flushing the eyes and face without choking the victim).
• A gym, hotel, or residential shower stall.
• A garden hose or multiple 5-liter (1-gallon) jugs of water carried out from a grocery store or convenience store cooler.
• What if literally zero water is available in the first 30 seconds? If you are in a vehicle or park with zero tap or bottled water, use any cold, non-alcoholic, non-corrosive watery beverage available (such as cold unsweetened tea, sports drinks, or saline contact lens solution) for the first 30 seconds while sprinting to a water tap. However, once tap water is reachable, use ONLY clean running water or sterile saline; do not pour milk into chemical eye burns, because milk is non-sterile and forms opaque curds with acid that obscure the ophthalmologist's view of the cornea.

Step 3: Proper Irrigation Mechanics (Preventing "Runoff Cross-Contamination")¶

How you pour the water matters almost as much as how much water you pour. Bad pouring angles can accidentally wash concentrated acid off a person's forehead or hair straight into their uninjured eyes or mouth:

1. If the chemical is in the HAIR or on the FOREHEAD, tilt the head BACKWARD or SIDEWAYS: Never stand a victim upright and pour a bucket of water onto the top of their acid-soaked hair, or the toxic runoff will cascade straight down over their eyebrows into both eyes and mouth. Have the victim lean their head backward over a sink (like at a hair salon) or sideways toward the burned cheek so the water runs directly off onto the floor.
2. If ONE EYE is burned, tilt the head so the INJURED EYE is on the BOTTOM:
3. Have the victim lie down or lean their head sideways so the burned eye is closer to the floor than the healthy eye.
4. Pour a gentle, steady stream of water onto the bridge of the nose, letting it flow across the inner corner of the burned eye and drain outward off the temple and cheek onto the ground.
5. ** Kuraho Lens ya Contact ako kanya **: Niba uwahohotewe yambaye lens yoroheje cyangwa ikomeye, imiti ihinduka umutego munsi yinzira ya plastike nkigikombe cyokunywa kuri cornea. Nyuma yo koza amasegonda 60, saba uwahohotewe guhumbya cyangwa gusohora lens ya contact ukoresheje urutoki rutose (cyangwa usukure neza kugeza igihe lens ireremba).
6. ** Fungura ijisho (Eversion) niba ibice bihari **: Saba uwahohotewe kuzunguza ijisho hejuru, hepfo, ibumoso, no iburyo uhoraho mugihe ufashe ibifuniko bifunguye munsi yumugezi wamazi kugirango amazi asohokane mumifuka yimbitse munsi yijisho ryo hejuru no hepfo (amahuriro ya conjunctival) aho uduce twa caustic twihishe.

5. An Open Cup or Mug Carried Toward You by an Angry Stranger or Ex-Partner: During a verbal argument outside a bar, workplace, or home threshold, anyone approaching within 4 meters (13 feet) holding an open paper coffee cup, glass, or thermos without drinking from it should be treated as a potential liquid-throw threat.

Exact physical evasion tactics in the 2 seconds before a liquid is thrown¶

If you see an aggressor pull out a squirt bottle or draw back an open cup during a confrontation:

• Turn your face away 180 degrees and bury your eyes into your crooked elbow immediately: Protecting your corneas and airway is 100 times more important than protecting the back of your jacket or shoulder. The instant someone squeezes a bottle or swings a cup toward you, spin your head and torso completely away, clamp your eyelids shut, tuck your chin into your chest, and press your face into the crook of your arm while sprinting away laterally. Taking a splash of acid on the back of a thick denim or nylon jacket allows you to rip the jacket off in two seconds with zero injury, whereas taking that same splash across open eyes can cause permanent blindness.
• If riding a motorcycle, scooter, or bicycle, keep your helmet polycarbonate visor snapped DOWN in urban traffic: Never ride or stop at urban traffic lights with your full-face helmet visor flipped open. A closed polycarbonate helmet visor (or wrap-around cycling glasses) blocks 100 percent of a direct squirt-bottle stream to the eyes; if splashed on your closed helmet visor, do not flip the visor up with your bare hand. Pull away from the attacker, stop in a safe spot, unbuckle the chin strap, and pull the entire helmet forward off your head while keeping your eyes closed.
• If inside a car, keep windows rolled up at traffic lights: As covered in our carjacking defense guide, keeping your car windows rolled up at urban intersections completely defeats moped squirt-bottle attacks.

What happens in the ambulance and hospital: Diphoterine, Morgan Lens, and Burn Center care¶

Understanding how paramedics and emergency physicians treat corrosive burns helps you cooperate effectively during transport and advocate for complete decontamination:

1. Litmus pH Testing of the Eye and Skin:
2. Paramedics and emergency room nurses use small litmus pH indicator strips pressed gently against the lower eyelid pocket (fornix) and burned skin to measure acidity or alkalinity.
3. Normal human tears have a neutral pH of 7.0 to 7.4. If the litmus strip reads below 6.5 (acidic) or above 7.6 (alkaline, often pH 11 to 14 after a drain-cleaner attack), irrigation must continue without stopping, sometimes requiring 2 to 4 liters (0.5 to 1 gallon) of sterile normal saline or Lactated Ringer's solution per eye.
4. Morgan Lens Continuous Eye Irrigation:
5. At the Emergency Department, the doctor will instill anesthetic numbing eye drops (such as proparacaine or tetracaine) to stop the painful eyelid spasms, sweep underneath the upper and lower eyelids with a moistened cotton swab to remove any trapped solid lime or lye particles, and insert a Morgan Lens, a small, smooth plastic contact-lens device connected to an IV bag of sterile saline that floats gently on top of the eyeball and bathes the cornea continuously for 30 to 60 minutes until the pH normalizes and stays normal 30 minutes after stopping.
6. Amphoteric Washing Solutions (Diphoterine) in Fire/HazMat Units:
7. Many UK Fire and Rescue Services, European ambulance teams, and industrial HazMat units carry sterile amphoteric, hypertonic chelating solutions (such as Diphoterine) in spray canisters and eyewash bottles. Unlike baking soda or vinegar, amphoteric molecules gently bind both acid protons (\(H^+\)) and alkali hydroxide ions (\(OH^-\)) without generating any exothermic heat, while their hypertonic osmotic pressure helps draw chemical ions back out of the outer corneal and skin layers. However, you must never delay water irrigation to wait for Diphoterine: start flushing with tap or bottled water in the first 10 seconds, and switch to sterile saline or Diphoterine when EMS arrives.
8. Specialist Referral to an Ophthalmologist and Regional Burn Center:
9. Every chemical eye burn requires an urgent same-day slit-lamp examination by an ophthalmologist (who may prescribe topical ascorbate/citrate drops, cycloplegics, antibiotic ointment, or amniotic membrane grafts to help corneal stem cells regenerate).
10. Deep facial, neck, hand, or large-area chemical skin burns are transferred to a specialized Regional Burn Center for tangential excision, grafting, and scar-contracture prevention.

Special warning: Hydrofluoric Acid (HF) and White Phosphorus exposures¶

While 95 percent of street chemical assaults involve sulfuric acid, hydrochloric acid, ammonia, or sodium hydroxide drain cleaner, two specific industrial chemicals cause systemic fatal toxicity even from a small skin splash and require specialized hospital antidotes:

Protecting the airway and monitoring for systemic shock while waiting for EMS¶

When a corrosive liquid is splashed onto the lower face, mouth, or neck, two secondary medical emergencies can develop within 10 to 20 minutes while you are still irrigating the skin:

1. Upper Airway Swelling (Laryngeal Edema) and Inhalation Injury:
2. If the victim swallowed even a drop of the liquid, got chemical inside their mouth, or inhaled strong fumes from fuming nitric/hydrochloric acid or industrial ammonia, the delicate vocal cords and upper trachea can swell shut rapidly.
3. Warning signs of imminent airway closure: Hoarse or raspy voice, high-pitched whistling sound when inhaling (stridor), drooling or inability to swallow saliva, blistering on the lips or tongue, and shortness of breath.
4. Immediate action: Keep the victim sitting upright or leaning slightly forward (never lay a patient with facial/oral chemical burns flat on their back), have them rinse and spit out mouthfuls of cold water repeatedly (never make them drink water or induce vomiting if they swallowed a corrosive, as vomiting burns the esophagus a second time), and alert the 911 / 112 / 999 dispatcher that the patient has stridor/airway burns so an advanced paramedic crew brings rapid-sequence intubation equipment.
5. Preventing Hypothermia During 30-Minute Water Irrigation:
6. Drenching an adult or child with cold tap or hose water for 30 to 45 minutes after cutting off their clothes can cause severe hypothermia, especially outdoors in cool weather.
7. Targeted irrigation: Focus the continuous stream of lukewarm or cool tap water strictly on the burned anatomical zones (such as the face, neck, and right arm) while wrapping the victim's unburned legs and torso in dry blankets, coats, or foil thermal blankets.
8. Never wrap a chemical burn in dry cotton wool or tight bandages before irrigation is complete:
9. Once paramedics arrive or after 30 to 60 minutes of continuous water flushing, cover the irrigated skin burns loosely with clean plastic kitchen cling-film (laid longitudinally along the limb, never wrapped tightly around like a tourniquet) or a sterile wet saline dressing. See our severe burns and chemical flushing guide.
10. Preserve the chemical container or photograph it from a distance for Poison Control:
11. If the attacker dropped the cup, bottle, or drain-cleaner container on the ground, do not pick it up with your bare hands. Point it out to the first arriving police officer or take a clear zoom photo of the label so hospital doctors and Poison Control (1-800-222-1222 in the United States) know the exact chemical formula and pH immediately.

Ibibazo bikunze kubazwa¶

Why shouldn't I pour milk, baking soda, or vinegar on an acid or chemical burn to neutralize it?¶

Never apply baking soda, vinegar, lemon juice, or any chemical neutralizer to an acid or alkali burn on human skin or eyes. When an acid mixes with a base, it triggers an exothermic chemical reaction that releases intense heat directly onto the already-damaged tissue, adding a severe thermal heat burn on top of the chemical burn. Similarly, pouring milk into a chemical eye injury is strongly discouraged by ophthalmologists because milk is non-sterile and curdles when mixed with acid, creating opaque white protein clumps that trap chemicals under the eyelids and block doctors from seeing the cornea. Clean, cool running tap water or sterile saline is the universal gold-standard treatment.

How long should I keep flushing the skin and eyes with water after a corrosive attack?¶

You must flush a corrosive chemical burn with continuous running water for a minimum of 20 to 30 minutes for acid burns and 30 to 60 minutes or longer for alkali (drain cleaner/lye) burns or any splash involving the eyes. Do not stop flushing after five minutes just because the skin looks clean; caustic chemicals soak into the deeper layers of the skin and cornea and continue destroying cells until paramedics arrive and verify with litmus pH strips that the tear film and skin surface have returned to a neutral pH of 7.0 to 7.4.

What should I do if there is no sink or tap water nearby when someone is splashed with acid on the street?¶

Immediately shout to every bystander, driver, and nearby shopkeeper to bring any bottled drinking water they have in their bags or cars, and pour that water over the victim's eyes and face within the first 15 seconds while guiding the victim inside the nearest restaurant, coffee shop, hair salon, bar, or residence to reach a sink faucet or shower. If literally zero water is reachable in the first 30 seconds, use any cold, watery, non-alcoholic drink (such as cold tea or sports drink) as an instant bridge to dilute the acid while running to the nearest tap.

How do I remove a victim's acid-soaked shirt without spreading the chemical onto their face or burning my own hands?¶

Never pull a chemical-soaked T-shirt, sweater, or dress upward over the victim's head, as doing so wipes the wet acid across their nose, mouth, and eyes. Instead, keep water running over the victim while using scissors, a pocketknife, or tearing down the collar seam to cut the clothing off from top to bottom, and slip plastic bags, nitrile gloves, or a thick dry cloth over your own hands so you do not transfer corrosive residue onto your fingers.
