The message
from "Bob Mannix" contains these words:


The same crazy logic which demands that there should be water fire
extinguishers available in locations where the only conceivable risk is
of an electrical fire, and now demands that the water and powder
extinguishers should be so similar that the only difference is in the
colour of the label.


Water fire extinguishers are provided in corridors etc, for tackiling
office
paper fires through the door. Inside offices with, eg, computers, there
should be CO2 fire extinguishers. The colour coding still exists on the
label and water fire extinguishers are fairly easily discernible from CO2
ones but the change from whole body colouring to the label seeems to be
universally condemned as...

I was thinking of the sanctuary area of a church. No candles. No
smoking going on. Only reasonably conceivable risk would be from
electrical sources.
