I’ve modified this Original Reddit Post a bit. Let me know your thoughts and criticisms, if there is anything I should add, or correct.

Also, fuck Reddit and Spez of course. However we should be pragmatic. There is a vast amount of information on reddit and a lot more people use it for now. I’m manually moving things I feel are important on to the Fediverse for archival and general use purposes. And sharing sources for full disclosure.

Know your rights at protests

Basic Tech Security Practices

Practical protest prep

  • Go with a buddy, set a check-in time, write an emergency contact on paper.
  • Bring water, needed medications, earplugs, weather gear.
  • Don’t bring a cell phone, unless it is free of personal data and hard to trace back to you.
  • Consider disabling FaceID/biometrics and using a passcode on your primary cell phone.
  • Decide in advance what your risk tolerance is; leave early if things escalate.
  • Bring a first aid kit if you know how to use it.
  • Wear protective clothing
    • Eye Protection
    • Ear Protection
    • Gas mask
  • have an escape route
  • don’t let yourself be kettled or corralled
  • be aware of your surroundings

How to deal with Chemical Irritants (Pepper Spray and CS Gas) in eyes

What to do after exposure to pepper spray

  • Move into an area with fresh air, if possible.
  • Flush the affected area to wash away the contaminants.
  • Avoid using soap around the eyes as it is an irritant.
  • Remove clothing that may have come into contact with the spray to decontaminate and prevent re-contamination. Cutting off clothing rather than pulling it over the head helps avoid further irritation to the eyes and skin.
  • Avoid touching the affected area, as it is easy to spread the oil-based solution to other areas of the body by doing so.
  • Blink the eyes rapidly to help flush out the chemical.

In most cases, pepper spray symptoms resolve within 10 to 30 minutes and do not require medical care.

  • Popular strategies for removing pepper spray include baby shampoo, milk, antacids, and lidocaine. However, an older 2008 study comparing these strategies found no evidence that they were more effective than water.
  • A 2018 randomized controlled trial also reported no difference between baby shampoo and water alone in relieving the effects of tear gas and pepper spray.

Treatment Methods

  • Sterile saline solution [safest method]
  • Distilled water (safe and cheap if a lot is needed)
  • liquid antacid solution (Many claim to prefer but does introduce some risks)
    • Understanding and Dealing with Pepper Spray - Street Medics [video]
    • how to make
      • 50% liquid antacid (Magnesium Hydroxide or Aluminum Hydroxide)
        • Max alcohol of 0.20%
        • No mint/citrus flavor
      • 50% distilled water
      • If keeping as a backup in a kit, add water preserver and store in opaque HDPE containers
    • possible risks
      • not sterile
      • might introduce harmful chemicals if the wrong ingredients are used, if bottles are cleaned incorrectly
      • might introduce allergen
      • might be contaminated from improper preparation

  • Move into an area with fresh air, if possible.

  • Treat eyes with as with other chemical irritants above
  • Wash skin with soap immediately

    I don’t know what exactly the topic was, but I gues it might have been ham radio, in which case, yeah, it can’t be encrypted, but you would also need a license and ID yourself with your callsign. Found the link.

    Transmission Frequency:
136-174 MHz / 400-470 MHz

    Meshtastic uses (one of) license free bands (915MHz), that’s basically free for all with Tx power limits. But that also means a lot of RFI from many random devices: thermometers, car keys, etc.
