How many fire extinguishers do you need to install?

We created a short and simple calculation guide to allow you to work out how many fire extinguishers you need. If you know the floor space of your premises you can easily work out your class A requirement for fire extinguishers. We also added simple pointers helping you to identify further risks, such as Class B requirements, electrical risks and specialist risks such as Class F in kitchens. At the end you can work out what type of extinguisher you need and how many extinguishers you require.
