Lots.

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.

Mel,
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?!)

Thanks Avioniker. I was just browsing through the B752 AMM preparing for a future QECA change & was wondering what the caution really meant.But I'll def remember this in future.

Of course that's completely incorrect. For some reason I was thinking of Bismuth when I wrote that...

Yes, exactly. It is known as Chronic Beryllium Disorder (CBD). It is not curable so stay well clear of it and wear appropriate safetly clothing.
