If you've landed on this first aid page, you might need fast answers and immediate help for a Byrna-related injury.
Whether you've been hit by a kinetic round, exposed to a chemical irritant, or dealing with bruising and welts, knowing how to treat your wounds quickly and correctly is crucial.
Byrna guns are non-lethal self-defense weapons, but that doesn’t mean they’re harmless. These CO₂-powered projectiles are designed to incapacitate an attacker without causing fatal injuries.
This guide will provide immediate first aid steps to help you recover, including:
✅ Types of Byrna gun wounds & projectiles
✅ First aid for chemical exposure & your injuries
✅ How Byrna gun wounds compare to firearm injuries
Otherwise, I better get started in case you need medical attention.
How Serious Are Byrna Gun Wounds?
Many people wonder: Can a Byrna gun cause serious injuries? The answer depends on the distance, projectile type, and point of impact.
Byrna Gun Wound Effects:
✔ Skin Bruising & Welts – Common with kinetic rounds.
✔ Minor Skin Penetration – Possible at close range.
✔ Temporary Vision Loss & Respiratory Issues – If pepper rounds hit the face.
✔ Bone Fractures – Unlikely but possible at very close range.
Byrna Self-Defense Projectiles & Wounds
Byrna launchers use several types of chemical and kinetic rounds, each formulated for different effects:
Byrna Max Projectiles – Contain OC, CS, and PAVA for maximum irritation.
Byrna Pepper Projectiles – Include OC and PAVA for painful eye and respiratory irritation.
Byrna Black Projectiles – A combination of OC, CS, and PAVA similar to Byrna Max.
Byrna Training Projectiles – Contain talc powder for practice scenarios.
Byrna Eco-Kinetic Projectiles – Water-soluble plastic rounds designed for practice shooting with no chemical irritants.
While kinetic projectiles primarily cause bruising, welts, or minor skin abrasions, chemical irritants can lead to severe reactions, allergic responses, and respiratory distress.
🚨First Aid for Byrna Chemical Exposure & Impact Injuries
Question 1: Have You Inhaled Chemical Irritants?
🔹 Move to Fresh Air Immediately – Remove the affected person from contaminated areas.
🔹 Monitor for Breathing Difficulties – Those with asthma, COPD, or other respiratory conditions may require emergency medical attention.
🔹 Provide Oxygen if Needed – If the individual is struggling to breathe, oxygen therapy may help reduce discomfort. Seek urgent medical care if symptoms worsen.
💡 Warning: Prolonged exposure or severe reactions can lead to permanent lung damage. Individuals experiencing severe coughing, wheezing, or airway constriction should be evaluated by a doctor immediately.
Question 2: Has A Chemical Contacted Your Skin?
🔹 Wash Affected Areas Immediately – Use soap and water to remove residue. Do not scrub aggressively, as it may increase irritation.
🔹 Avoid Oils or Lotions – These may trap irritants and prolong symptoms.
🔹 Seek Medical Attention for Persistent Reactions – If redness, chemical burns, or allergic reactions develop, consult a doctor.
💡 Did You Know? CS irritant can cause chemical burns or induce allergic contact dermatitis, which may require topical steroids or antihistamines for relief.
Question 3: Has It Contacted Your Eyes?
🔹 Flush with Running Water for Several Minutes – Hold the affected eye(s) under cool, clean water for at least 15 minutes. 🔹 Remove Contact Lenses Immediately – If present, remove lenses before flushing the eyes.
🔹 Seek Medical Help if Symptoms Persist – Severe exposure can cause corneal scarring, leading to permanent vision impairment.
💡 Warning: If vision loss, blurred vision, or intense pain occurs, consult an ophthalmologist immediately.
Question 4: Was there Accidental Swallowing?
🔹 Rinse the Mouth Thoroughly – Avoid swallowing additional irritants.
🔹 Drink Plenty of Water – This helps dilute any remaining chemical residue.
🔹 Do NOT Induce Vomiting – Vomiting could worsen exposure by bringing the chemical into contact with sensitive throat tissues.
🔹 Call Emergency Services Immediately – Byrna chemical agents are not meant for ingestion and can cause serious gastrointestinal distress.
💡When It's A Medical Emergency: Symptoms such as severe throat pain, vomiting, difficulty swallowing, or dizziness require immediate medical intervention.
Key Symptoms and Long-Term Health Risks
Immediate Effects of Byrna Chemical Irritants:
✔ Respiratory Irritation – Coughing, wheezing, and difficulty breathing.
✔ Eye Irritation – Redness, swelling, and impaired vision.
✔ Skin Reactions – Burning, rash, or allergic contact dermatitis.
✔ Allergic Reactions – Anaphylaxis or severe inflammation (rare but possible).
💡 Severe Cases – Close-range exposure or prolonged inhalation may lead to permanent vision loss, lung damage, or long-term respiratory complications.
Critical Warnings and When to Seek Emergency Medical Help
🛑 Keep in Mind: Suspected Carcinogenic Risk – Some Byrna chemical formulations contain N-vanillylnonanamide, which is suspected of causing cancer through inhalation exposure.
🚨 Call Emergency Services if the Individual:
Has severe difficulty breathing or loss of consciousness
Experiences extreme swelling of the eyes, throat, or airway
Shows signs of anaphylactic shock (swelling, low blood pressure, difficulty breathing)
Has persistent vision impairment or severe skin burns
Is There A Difference Between Byrna Gun vs. Firearm Injuries?
Yes, Byrna gun injuries are fundamentally different from firearm injuries. While Byrna guns are non-lethal, they do cause pain, welts, bruising, and irritation. Firearms, on the other hand, cause life-threatening injuries with deep penetration and internal damage.
Key Differences Between Byrna & Firearm Injuries
Factor | Byrna Gun Injuries | Firearm Injuries |
Mechanism of Injury | Kinetic rounds or chemical agents cause external impact & irritation | Bullets penetrate soft tissue, bones & organs |
Lethality | Non-lethal, can cause pain, bruising or temporary incapacitation | Lethal or permanently disabling due to deep wounds |
Internal Damage | Minimal—impact is mostly superficial | High—bullets can shatter bones, puncture lungs, or cause internal bleeding |
Eye Injuries | Pepper rounds can cause temporary blindness, corneal damage | Bullets destroy the eye and surrounding structures permanently |
Respiratory Impact | CS & OC rounds cause difficulty breathing, coughing & throat irritation | Bullet wounds in the chest can collapse lungs or cause fatal bleeding |
Pain Level | High at close range, but pain fades within hours or days | Intense pain with long-term or permanent nerve and tissue damage |
Treatment Required | Usually first aid (ice packs, flushing irritants, skin treatment) | Emergency surgery, blood transfusions, or ICU care |
Wound Severity Based on Range and Projectile Type
1️⃣ At Close Range (5-10 feet):
Byrna kinetic rounds can break skin, cause deep bruising, or small lacerations.
Firearm bullets cause penetration wounds with internal trauma.
2️⃣ At Medium Range (15-30 feet):
Byrna rounds deliver strong impact, causing welts and pain but little internal harm.
Firearm bullets still have high velocity and can penetrate deeply, hitting major organs.
3️⃣ At Long Range (30+ feet):
Byrna rounds lose energy, causing mild bruising or irritation.
Firearm bullets remain deadly, depending on caliber and power.
My Best Practices for Using a Byrna Gun Safely
