Key warning: Potential dangers if misused
Section 1: Understanding UV-C Technology
(800 words)
1.1 How UV Disinfection Works
Germicidal range: 200-280nm (UV-C band)
Effectiveness against viruses (incl. COVID-19), bacteria & mold
Limitations: Shadowed areas, material compatibility
1.2 Types of UV Sanitizers
Handheld wands (Munchkin UV Sterilizer)
Closed-chamber boxes (PhoneSoap Pro)
Whole-room systems (Hospital-grade Tru-D)
HVAC-integrated units (RGF REME HALO)
Section 2: Choosing the Right Device
(1000 words)
2.1 Safety Certifications to Look For
FDA-cleared vs. FDA-approved
IEC 62471 photobiological safety standard
EPA registration for commercial units
2.2 Calculating Proper Dosage
μW/cm² intensity measurement
Exposure time formulas (e.g., 10,000 μW-sec/cm² for 99.9% kill)
Using UV-C meters like Sper Scientific 850009
2.3 Material Compatibility Guide
Safe: Glass, stainless steel, silicone
Risky: Plastics (yellowing), rubber (degradation)
Never expose: Skin, eyes, living plants
Section 3: Step-by-Step Usage Protocol
(1200 words)
