A product demo gone wrong sent a holiday craft fair into a brief panic, but no one was seriously hurt.

• A vendor's pepper spray device went off by accident during a demo at the Blaisdell Exhibition Hall, filling the room with fumes.
• Shoppers and vendors coughed and had watery eyes, and the building was evacuated for about an hour while crews checked it out.
• Fourteen people were checked out by medics on scene, and all of them turned down a trip to the hospital.
• Organizers say product demos aren't supposed to happen at the fair, and this is the first time anything like this has occurred.

Outlook: The fair reopened after hazmat crews cleared the hall, and organizers are expected to tighten rules on in-booth product demos going forward.
