The least pleasant hazard is Berylliosis, which basically rots your lungs over a period of years. It can be triggered by a single exposure. Then it's carcinogenic, and can cause severe skin, respiratory and digestive system irritation. Beryllium is also a heavy metal, and has similar toxicity to most other heavy metals.
Google for "beryllium oxide msds" and you'll find many material data safety sheets with details.
Its toxicity is a major reason its use in florescent lights was stopped in the late 40s.

It's the Blue or Purple banded igniters. Wear a good respirator if your company uses them and wash the H... out of your hands and arms after you take the gloves off (you WERE wearing nitrile gloves weren't you?!)
