Trauma Supply
Expiration Dates
You bought an IFAK. You stored it. You haven't touched it since. Then you wonder: Does this stuff expire? Can I still use it if the date passed? Is my tourniquet still good after 5 years in a hot truck? Here's the truth: Some expiration dates are hard limits. Others are manufacturer CYA dates. Using expired gear can mean life or death.
Not all expiration dates are created equal. Real Expiration: The product chemically degrades past this date. It won't work. CYA Expiration: The product is probably fine, but the manufacturer can't guarantee performance without costly long-term testing. Here's the breakdown.
Hemorrhage Control
Tourniquets (CAT, SOF-T, RATS)
Safe Past Date? Yes, with inspection
What Degrades: Velcro (loses adhesion), plastic buckle (brittle with UV), strap (dry rot)
Inspection: Pull strap hard (Velcro should hold), flex buckle (should bend smoothly), rotate windlass (should turn freely), check for white powder on strap (replace if present)
Hemostatic Gauze (QuikClot, Celox, ChitoGauze)
Safe Past Date? NO. Replace on date.
Why: Kaolin or chitosan coating loses hemostatic properties. Once degraded, it's just regular gauze. You won't know it failed until you need it.
Verdict: CRITICAL REPLACE. Do not use past expiration.
Pressure Bandages (Israeli, OLAES, ETD)
Safe Past Date? Yes, 2-5 years past with inspection
Inspection: Stretch bandage (should recoil), check pressure bar (no cracks), open package (replace if gauze smells musty)
Airway & Breathing
Chest Seals (Hyfin, Halo, NuSeal)
Safe Past Date? NO. Replace on date.
Why: Adhesive dries out and loses tackiness. Foil pouch can develop micro-tears. If adhesive fails, air enters chest cavity causing tension pneumothorax. You can't test adhesion without opening.
Verdict: CRITICAL REPLACE. Adhesive failure is silent and fatal.
Nasopharyngeal Airways (NPA)
Safe Past Date? Yes, 2-3 years past with inspection
Inspection: Flex tube (should bend smoothly), check flange (no cracks), feel surface (replace if sticky or gummy)
CPR Masks / Pocket Masks
Safe Past Date? Yes, 5+ years past with inspection
Inspection: Blow through valve (air should only go one direction), squeeze cushion (should rebound), check for cracks
Personal Protection
Nitrile Gloves
Safe Past Date? Yes, 2-3 years past with inspection
Inspection: Pull glove (should stretch, not tear), feel surface (replace if sticky or gummy), check for yellowing discoloration
Latex Gloves
Safe Past Date? NO. Replace on date.
Why: Latex degrades faster than nitrile, becomes brittle, loses elasticity, allergen potential increases with age
Tools & Miscellaneous
SAM Splints
Safe Past Date? Yes, indefinitely
What Degrades: Foam padding (can separate from aluminum), adhesive on padding
Verdict: Indefinite shelf life. Replace only if physically damaged.
Trauma Shears
Safe Past Date? Yes, indefinitely
Inspection: Cut through denim (should slice cleanly), open/close pivot (should be smooth), check for rust or corrosion
Verdict: Indefinite shelf life. Sharpen blades as needed.
Thermal Blankets (Space Blankets)
Safe Past Date? Yes, 5-10 years past with inspection
Inspection: Unfold blanket (foil should not peel), check for holes or tears, feel material (replace if brittle)
Quick Reference: Replace vs. Inspect
| Product | Replace on Date? | Safe Past Expiration? | Notes |
|---|---|---|---|
| Tourniquet | No | Yes (2-5 years) | Inspect Velcro, buckle, strap |
| Hemostatic Gauze | YES | NO | Chemical degradation is real |
| Chest Seals | YES | NO | Adhesive failure is silent/fatal |
| Pressure Bandage | No | Yes (2-5 years) | Check elastic, pressure bar |
| NPA | No | Yes (2-3 years) | Check for brittleness |
| CPR Mask | No | Yes (5+ years) | Test one-way valve |
| Nitrile Gloves | No | Yes (2-3 years) | Replace if sticky/brittle |
| SAM Splint | N/A | Indefinite | No expiration |
| Trauma Shears | N/A | Indefinite | Sharpen as needed |
| Thermal Blanket | No | Yes (5-10 years) | Check foil integrity |
The Bottom Line
Some expiration dates are real. Some are conservative. Knowing the difference matters when your life depends on your gear.
Hard Rules: Hemostatic gauze: Replace on date. No exceptions. Chest seals: Replace on date. No exceptions. Everything else: Inspect, test, and use judgment.
Storage Matters: Cool, dry, dark = maximum shelf life. Hot vehicle = reduce shelf life by 30-50%. Moisture exposure = immediate replacement.
Audit your kit quarterly. Replace what's expired. Test what's questionable. And when you need it, you'll know it works.
