Re: Tossing water at electric fire
I remember having to point out to someone that CO2 was fine for a small enclosed kitchen, but that Halon was definitely a bad idea.
The estates management people in our current office came around and re-did our extinguishers this year. There are only 2 rooms on the top floor, and I've now got 2 water and a CO2 extinguisher to play with. Which snazzy glow-in-the-dark tops on.
Which would be great if they weren't all now stupidly painted red - so you can't tell them apart without looking closer. If they wanted to do that for visibility, they should have mandated a band of colour at the top - so you could easily tell the type.
