There is no accreditation required for running any such course.
Basics are:
This is a fire extinguisher, this is how it works, here are what the different types are for. Don't hold on to the cone when using a co2, your hand will freeze to it.
Make sure you are safe.
If you can't safely put out a fire with a small cup of water then its best just to leave it.
People always try to leave the same way as they came in - even if they are right next to a fire exit.
Keep fire exits clear whenever the premises are open.
Make sure the door actually works and opens and is free from obstruction at the other side.
Fire alarm should be tested once a week from a different point every time in rotation.
Always remember to keep the way clear for the fire brigade arriving
Don't re enter til the fire brigade tell you it's clear.
Now search you tube for the bradford fire disaster from 11th May 1985 and watch the video
Fire spreads quickly
its dangerous.
Course done.
Now gimme yer £85 and I will send you a certificate
OF COURSE any and all training is always useful, especially health and safety training, but don't expect any more than I have just described...
Hope this helps
