Shortwave ultraviolet causes eye and skin injury with no warning glare. This standard sets the shielding, signage, and exposure limits for fluorescent-mineral displays, and the presenter responsibilities for keeping hands and faces out of the beam.
Why this matters
Shortwave UV injures eyes and skin without any sensation of brightness — the hazard is precisely that nothing warns you. Every requirement in the checklist exists because the lamp gives no second chances and the minerals look so good that people lean in. The fluorescence guide covers what to show; this standard covers how to still be able to see it next year.
