This isn't a joke, this is valuable fire safety advice. It is a good idea to fit fire alarms and sprinkler system to any reasonably sized industrial or commercial premises. Don't just take my word for it, all UK fire services will be prepared to advise you on this matter. Contact your local fire service (they used to be called "brigades")for advice.
Here is a news item about one organisation that didn't bother:

If you are worried about looking at links posted by someone who hasn't logged in much lately, you could always visit the BBC website, navigate to the England news story pager, click on East Anglia on the little map, and then look under 'Norfolk'.
