PSA: How to prevent permanent damage from Tear Gas or CS spray


  • If you have medical conditions such as asthma or any sort of respiratory disease, you might want to keep your inhaler/medication on hand.


  • CS spray and tear gas are the same thing. CS spray is just the technical shorthand (full name is 2-chlorobenzalmalononitrile)

1) Get away from the gas.

2) Eyes: Rinse with clean water for at least 15 minutes. Remove contacts and DO NOT REUSE, wash glasses with soap and water

3) Breathing: Take deep breaths. Blow snot rockets as follows:

  • Hold your index finger to the side of your nose a push one nostril shut.
  • Lean your body to the side of your nose that’s open.
  • Deep breath in.
  • Close your mouth and forcefully blow out your nose.
  • Repeat on the other side.

4) Rinse your mouth, preferably with milk or antacid. DO NOT SWALLOW!!!

5) Clothing: remove any clothing covered in CS

  • Avoid removing clothing or jewellery over your head, cut it off if possible
  • Wash your body with soap and cool water (Warm water dilates pores so the gas will get deeper in and burn more) for about 20 minutes

6) Cleaning:

  • Wash contaminated clothing separately from the rest of your laundry.
  • Clean any jewellery with soap and water.
  • DO NOT use any detergent containing Chlorine Bleach (Chlorine bleach and CS gas can form Chlorine dioxide, a highly dangerous neurotoxin.)

If you follow all of these steps, the worst will be over in half an hour.
