Drying rooms should be completely dark

For optimal drying results, storage and processing areas must maintain total darkness. This prevents light exposure that could damage materials or affect drying processes.

Why Complete Darkness Matters

• Prevents photochemical reactions in sensitive materials
• Maintains product integrity and quality standards
• Reduces risk of degradation from UV exposure
• Ensures consistent drying outcomes

Darkness Requirements by Material Type

1. Photographic materials: Must be stored in complete darkness
2. Chemical compounds: Require lightproof storage to prevent decomposition
3. Textiles: Should avoid light exposure to prevent fading
