Episode notes
Packaging Failure Causes Hidden Risk
- Packaging often fails in cold: plastic becomes brittle and glass can burst, causing occult leaks or contamination.
- Hairline cracks can let humidity or medication escape without obvious visual clues.
Keep Meds On Your Body
- Keep critical medications and kits on your person against your body to maintain warmth.
- Use base-layer pockets or vests that you cannot easily remove to prevent accidental exposure to cold.
Inspect Before You Inject
- Inspect frozen meds visually and avoid injecting anything with visible precipitate or obvious loss.
- When in doubt about unseen efficacy loss, assume compromised and seek alternatives or verified supplies.
