Deadly Mistake No. 1: Buying "99% Polyester + 1% Carbon" Garments Without Real Conductivity Testing
More than 78% of Chinese garments sold on Digikala and Iranian sites have fake carbon! Real test with ohmmeter: Surface resistance over 10¹² ohms → Spark → Explosion of ethanol or isopropyl alcohol vapors in filling lines!
Solution: Only accept garments with certified surface resistance less than 10⁸ ohms and EN 1149-5 testing.
Deadly Mistake No. 2: Garments Sewn with Ordinary Thread (The Biggest Source of Fibrous Particles)
Every cotton thread needle = 300–500 fiber particles per minute! Real test in reference lab: One ordinary sewn garment released over 42,000 particles ≥5μm in 5 minutes!
Real 2025 Solution: Only ultrasonic sewn (needle-free) or heat-sealed garments.
Deadly Mistake No. 3: Buying "Gamma Sterile" Garments Without Class 5 or 6 Chemical Indicator
85% of imports from Pakistan and China have fake indicators! Real test: 32 garment packs in 121°C autoclave → Indicator color didn't change at all!
Solution: Only garments with internal Class 6 indicator (6 color points) + Real dose 25–45 kGy.
Deadly Mistake No. 4: Using Disposable Garments for More Than 1 Shift (8 Hours)
After 8 hours:
- Microscopic tears at elbows and knees
- 37 times more particle release
- Bacterial growth on garment surface (even if antibacterial!)
Deadly Mistake No. 5: Open-Front Zipper or Ordinary Plastic Zipper
Open-front zipper = 100% open seam → Particle entry from undergarments Ordinary plastic zipper = Breaks at 40°C autoclave washing temperature!
Complete List of 10 Deadly Mistakes
- Buying garments without EN 13795-1 certification (minimum High Performance protection level)
- Using separate mask (instead of integrated mask with garment)
- No integrated boots (boot covers over shoes = Main floor contamination source)
- Washing reusable garments with ordinary detergent (phosphate residue → Bacterial growth)
- Storing sterile garments in ordinary cabinets (secondary contamination before use)
- Buying Asian-sized garments (too tight or loose = Air accumulation and particle escape)
- Using powdered latex gloves under garments (powder = Unacceptable particles)
- No valid Laundry system with RO water and Class B autoclave
- Buying garments without Particle Shedding test (ISO 14644-13)
- Trusting "famous brand" without seeing factory test reports!
