Dekontaminacija suzavcem, biber sprejom i sredstvom za kontrolu gužve i prva pomoć¶

Hemijski agensi za kontrolu gomile (obično se nazivaju sredstva za kontrolu nereda ili lakrimatori) uključuju CS gas (2-hlorobenzalmalononitril), OC biber sprej (oleoresin capsicum), PAVA (pelargonska kiselina vanililamid), i sintetičnu kapsaicinu**, a** (kloroacetofenon / Mace). Bilo da ste neuključeni putnik uhvaćen u blizini demonstracija, stanovnik komšiluka čiji je otvoreni prozor stana uvukao dim sa ulice, novinar ili pešak koji je slučajno izložen spreju za ličnu odbranu, akutna izloženost izaziva trenutni, intenzivan bol. Unutar dvije sekunde od kontakta s vlažnom sluznicom očiju, nosa, grla i vlažnom kožom, ova hemijska jedinjenja aktiviraju receptore boli (posebno TRPA1 i TRPV1 jonske kanale), izazivajući nevoljne grčeve očnih kapaka (blefarospazam), privremeno funkcionalno sljepilo, gušenje, zatezanje kože i zatezanje kože.

Za zdrave odrasle osobe na otvorenom, akutni efekti suzavca i biber spreja su obično privremeni i počinju da popuštaju u roku od 15 do 45 minuta nakon prelaska na svjež zrak i pravilnog ispiranja. Međutim, u zatvorenim prostorima, u visokim koncentracijama ili kod osoba s astmom, kroničnom opstruktivnom plućnom bolešću (KOPB), kardiovaskularnim bolestima ili kontaktnim sočivima, hemijski agensi za kontrolu gomile mogu izazvati po život opasan bronhospazam (teški napadi astme), opekotine i laringospazije-hemijski spazam kože, laringospazam, . Znati kako pobjeći od aerosolnog oblaka uz vjetar i uzbrdo, pravilno isprati oči čistom vodom ili sterilnom fiziološkom otopinom bez trljanja, izbjegavati opasne ulične mitove kao što je sipanje mlijeka ili antacida u oči i bezbedno dekontaminirati odjeću kod kuće sprečava trajne ozljede očiju i pluća.

Uradi ovo sada¶

1. Move immediately to fresh air by walking UPWIND and UPHILL (higher elevation). Tear gas aerosols and vaporized particles are significantly heavier than air and sink into low-lying streets, subways, basements, and ground floors. Walk calmly (do not run, as running makes you breathe deeper and faster) perpendicular to or into the wind, and climb to higher ground or an upper-floor balcony away from the white smoke cloud.
2. Nikada ne trljajte oči, lice ili kožu rukama. CS gas zapravo nije gas na sobnoj temperaturi; to je oblak mikroskopskih, oštrih kristalnih čvrstih čestica praha. Trljanjem očnih kapaka ovi mikroskopski kristali se melju direktno preko rožnjače poput brusnog papira, uzrokujući bolne ogrebotine rožnjače, i širi uljani OC biber sprej dublje u pore kože.
3. Remove contact lenses immediately with clean fingers and throw soft lenses away. Contact lenses trap concentrated chemical crystals and capsaicin oils directly against your eyeball underneath the lens, preventing water from washing the chemical out and melting or permanently contaminating soft hydrogel lenses. Wash or wipe your fingers first, pinch the lenses out immediately, and discard soft lenses permanently.
4. Blink rapidly and flush your eyes from the inner corner (near the nose) outward using clean cool water or sterile saline. Tilt your head sideways over a sink or ground area so the worse eye is facing downward (so contaminated runoff water does not wash across the bridge of your nose into your other eye or down into your mouth). Pour a steady, gentle stream of clean drinking water or sterile 0.9% normal saline from the inner corner of the eye near the nose outward toward the ear for 10 to 15 continuous minutes.
5. NEVER pour milk, liquid antacids (Maalox), vinegar, baking soda paste, or cooking oil into your eyes. Despite widespread internet rumors, pouring unsterile dairy milk, flavoured liquid antacids, or vinegar into eyes that have microscopic chemical scratches introduces bacteria (Pseudomonas and Staphylococcus), fungi, and particulate grit that can cause sight-threatening bacterial keratitis (corneal ulcers). Use only sterile saline or clean potable water inside the eyes.
6. Strip off contaminated outer clothing without pulling shirts over your head, and take a COLD shower. Once you reach a safe bathroom, cut off contaminated pull-over t-shirts with scissors (or unbutton shirts) so you do not drag powder-coated fabric back across your face and eyes. Step into a cold water shower for the first 5 minutes before applying mild dish soap: hot or warm water opens skin pores and reactivates intense burning from crystalline CS powder and capsaicin oil.

Identifying the chemical agent: CS Tear Gas vs. OC Pepper Spray vs. CN Mace¶

Razumijevanje kojem ste kemijskom agensu bili izloženi objašnjava kako se on ponaša na vašem tijelu i na površinama domaćinstva. Dok svi agensi za suzbijanje nereda izazivaju momentalno kidanje i peckanje, njihova se fizička kemija bitno razlikuje.

Zašto je CS "Gas" zapravo mikroskopski čvrsti prah¶

Najvažnija činjenica koju treba razumjeti o CS suzavcu je da to nije pravi plin. Na normalnim vanjskim temperaturama, CS je bijeli čvrsti kristal sličan talku ili fino mljevenom staklu. Kada se ispali kanister sa suzavcem, unutrašnje pirotehničko punjenje zagreva čvrsti CS dok ne ispari u vazduh; čim ta vruća para udari u hladan vanjski zrak, ona se ponovo kondenzira u gust oblak mikroskopskih čvrstih čestica prečnika od 1 do 10 mikrometara.

Zato što je CS čvrst prah koji hemijski reaguje sa vlagom:

• Znoj i vlaga aktiviraju opekotine: CS kristali se lijepe za znojna čela, vrat, pojaseve i mokre košulje. Kako kristal polako reaguje sa vlagom kože (hidroliza), on oslobađa mikroskopske količine hlorovodonične kiseline i iritantnih proizvoda razgradnje direktno na vaše nervne završetke.
• Duhavanje suhog zraka pomaže prije pranja: Jednom kada izađete iz CS oblaka na svjež vjetar, stajanje na jakom povjetarcu sa ispruženim rukama 3 do 5 minuta omogućava vjetru da otpuhne rastresiti suvi CS prah s vaše kose i odjeće prije nego što ih voda dotakne.

Korak po korak protokol za ispiranje očiju (i zašto ulični lijekovi uzrokuju sljepoću)¶

Vaše oči su najosetljivija meta hemijskih sredstava za kontrolu gomile. Kada CS kristali ili kapljice biber spreja padaju na suzni film rožnjače, trigeminalni nerv pokreće trenutni zaštitni refleks koji se zove blefarospazam, vaši se kapci zatvaraju tako čvrsto da ih ne možete otvoriti samo snagom volje.

Kako bezbedno isprati svoje ili tuđe oči¶

1. Postavite glavu nagnutu na stranu sa obolelim okom NISKO: Neka se osoba nagne napred ili nagne glavu u stranu pod uglom od 45 do 90 stepeni tako da oko koje se ispere bude na donjem delu. Nikada nemojte naginjati glavu pravo unazad dok sipate vodu preko čela: naginjanje glave unazad ispire hemijski prah sa čela i obrva pravo u oči i dole u usta.
2. Nežno držite kapke otvorene sa dva čista prsta: Pošto nevoljni blefarospazam zatvara kapke, voda koja se izlije preko zatvorenih kapaka ne čisti očnu jabučicu. Stavite čisti palac na gornju kost obrve, a kažiprst na donju jagodicu (nikada ne pritiskajući direktno na samu očnu jabučicu) i lagano razdvojite kapke tako da mlaz tečnosti udari u površinu oka.
3. Prelijte od UNUTRAŠNJEG ugla (kod mosta nosa) do VANJSKOG ugla: Držite bočicu sterilnog 0,9% normalnog fiziološkog rastvora za ispiranje očiju ili čistu bocu vode za piće 2,5 do 5 centimetara (1 do 2 inča) iznad unutrašnjeg ugla oka (pored nosa). Pustite da stabilan mlaz niskog pritiska teče preko oka i otiče iz vanjskog ugla pored sljepoočnice na tlo. Neka osoba okreće očnu jabučicu gore, dolje, lijevo i desno dok ispira vodu tako da se čestice zarobljene ispod gornjih i donjih kapaka ispiru.
4. Flush for a full 10 to 15 minutes: Do not stop after a two-second splash. Brief splashes of water on CS crystals briefly wet the powder and can make it sting more for 10 seconds before the volume of water carries the crystals away. Continuous irrigation for 10 to 15 minutes is what mechanically washes every crystal and oil droplet off the cornea.

Why you must NEVER put milk, Maalox (antacids), vinegar, or baby shampoo inside your eyes¶

During demonstrations and civil unrest, well-meaning bystanders frequently walk around carrying jugs of dairy milk, 50/50 mixtures of liquid antacid (LAW: Liquid Antacid and Water, such as Maalox or Mylanta), baking soda water, or baby shampoo to squirt into people's eyes. Ophthalmologists, poison control centers, and the American Academy of Ophthalmology warn strictly against putting any substance other than sterile saline or clean potable water into the human eye:

Skin and hair decontamination: the cold-water and dish-soap protocol¶

Once your eyes can open and your breathing is steady, you must remove the chemical residue clinging to your hair, face, neck, and clothing before you touch furniture, car seats, or family members at home.

Step 1: Undressing outside or inside a tiled bathroom¶

• Do not walk through your carpeted living room or sit on your fabric sofa wearing clothes exposed to tear gas or pepper spray. CS crystals and OC oils transfer instantly to upholstery and will off-gas and burn anyone who sits on that couch for weeks.
• Step into a tiled entryway, garage, or bathroom. Put on disposable nitrile or latex gloves if you have them.
• Never pull a contaminated t-shirt, sweatshirt, or sweater up over your head. Pulling a tight collar over your face scrapes all the CS powder and pepper spray that settled on your shoulders and chest straight into your eyes, nose, and mouth. Either unbutton the garment, pull your arms inside the sleeves first to lift it away from your face, or use heavy scissors to cut the shirt straight up the front seam and peel it off backward.
• Drop all contaminated clothes, shoes, and backpacks directly into a heavy-duty plastic trash bag and tie it shut until you are ready to wash them separately.

Step 2: The 5-minute COLD water shower rule¶

When you step into the shower to wash tear gas or pepper spray off your hair and body, turn the temperature knob all the way to COLD (or cool tepid water) for the first 5 minutes:

1. Why hot showers are agony: Hot or warm water causes immediate cutaneous vasodilation (rushing blood to the skin), opens sweat glands and pores wide, and melts oily OC resin and CS crystals so they penetrate deeper into the skin, reactivating a violent wave of burning across your entire body.
2. Stojte uspravno i nagnite glavu unazad (ili napred preko kade) kada ispirete kosu: Vaša kosa se ponaša kao džinovski filter za vazduh koji hvata ogromne količine prašine suzavca u vazduhu. Kada prvi put isperete kosu hladnom vodom, ne dozvolite da voda iz vašeg tjemena teče niz čelo u oči i niz grudi u prepone (prepone i genitalije imaju ultraosjetljivu sluzokožu koja će intenzivno izgorjeti ako kontaminirana tekućina tuširanja ispere vaš torzo). Savijte se naprijed u struku tako da voda iz kose istječe pravo na pod tuša.
3. Operite kožu izloženu OC biber spreju sa blagim tečnim sapunom za suđe za odmašćivanje: Pošto je OC biber sprej smola od čili ulja (kapsaicin), obična voda se sama otkotrlja sa ulja na vašoj koži. Nakon ispiranja pudera u prahu hladnom vodom 5 minuta, zapjenite lice (nežno zatvarajući kapke), vrat, ruke i šake blagim tekućim deterdžentom za pranje posuđa (kao što je Dawn ili Fairy tečnost) ili nježnim sredstvom za čišćenje lica bez ulja da emulgirate i podignite kapsaicin ulje s kože, a zatim hladnom vodom skinite kožu.
4. Pat dry with disposable paper towels rather than rubbing vigorously with a cloth bath towel.

How to protect your apartment or house if tear gas is deployed on your street¶

When crowd-control agents are deployed on urban streets outside residential apartment buildings, ground-floor and second-floor units frequently fill with drifting CS aerosol through window cracks, air conditioners, and bathroom vents.

How to safely launder tear-gas or pepper-spray clothing¶

Never toss a tear-gas-soaked jacket into the washing machine along with your child's clothes or your bedsheets; the chemical will transfer onto every item in the drum.

1. Wear disposable nitrile gloves when transferring clothes from the plastic bag into the washing machine.
2. Set the washing machine to COLD water only, highest water level, and an extra rinse cycle.
3. Add standard liquid laundry detergent plus 120 milliliters (one-half cup) of baking soda (sodium bicarbonate), which helps alkaline-hydrolyze and neutralize CS residue during the wash.
4. Run the cold wash cycle twice before touching the clothes.
5. Hang the clothes to air-dry outdoors or on a rack rather than putting them into a hot clothes dryer after the first wash (high dryer heat can bake any remaining trace of CS or OC into synthetic fibers and vent irritating fumes into your laundry room).
6. For leather boots, nylon backpacks, eyeglasses, and smartphones that cannot go in the washing machine, wipe them down three times outdoors using disposable paper towels soaked in cool water and mild dish soap, discarding each paper towel after a single swipe.
