For healthy adults in open air, the acute effects of tear gas and pepper spray are usually temporary and begin subsiding within 15 to 45 minutes after moving to fresh air and flushing properly. However, in enclosed spaces, high concentrations, or in people with asthma, chronic obstructive pulmonary disease (COPD), cardiovascular disease, or contact lenses, chemical crowd-control agents can trigger life-threatening bronchospasm (severe asthma attacks), laryngospasm, corneal abrasions, and second-degree chemical skin burns. Knowing how to escape the aerosol plume upwind and uphill, flush eyes properly with clean water or sterile saline without rubbing, avoid dangerous street myths like pouring milk or antacids into the eyes, and decontaminate clothing safely at home prevents permanent eye and lung injury.

Mee nke a ugbu a¶

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. Never rub your eyes, face, or skin with your hands. CS gas is not actually a gas at room temperature; it is a cloud of microscopic, sharp crystalline solid powder particles. Rubbing your eyelids grinds these microscopic crystals directly across your cornea like sandpaper, causing painful corneal abrasions, and spreads oily OC pepper spray deeper into your skin pores.
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.

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.
• Banye n'ụzọ mbata tiled, ebe a na-adọba ụgbọala, ma ọ bụ ụlọ ịsa ahụ. Yiri nitrile ma ọ bụ uwe aka latex enwere ike iwepu ma ọ bụrụ na ị nwere ha.
