Welcome along Mark.
Wish you well with your job search.
Don't know of anything specifically available at the moment but my advice is to keep an eye open for jobs with your local NHS Trusts, Primary Care Trusts, universities and colleges. They all tend to employ full time fire safety officers.
Also try places like airports, large industrial sites, as they may also employ fulltime fire safety professionals too.
And even if they don't have anything available straight away they might take your details to keep on file and because the profession is fairly close knit, and most fire safety officers belong to some form of association they may know someone who is looking to employ a fire safety officer !!!
Finally keep an eye on your local fire service websites. Many employ "civillian" (horrible phrase) inspecting officers, alot of brigades arent recruiting at the moment due to the credit crunch, but you never know. Keep looking!
Hope that helps - good luck!
