FYI
At my company, a crew procedure for Lithium Battery fire extinguishing in the cabin was brought into place during Summer 2004. Crew are tested on the procedure during annual 3 day SEP safety exams (just done mine - Hooray!)
Yes, I know that this doesn't affect cargo/checked bags, but I just thought I'd make you aware that there is some awareness of the issue, and also to let you know just how much better it feels when an SEP is safely behind you for another year. Now, if I can just get through the coming voluntary redundancy program without getting a corporate nudge...
