If you own or manage any type of commercial property then much of the responsibility to ensure it is safe falls on your shoulders, which is why one of your tasks, if you have not already done so, will be to speak to your local fire protection services company at integralfireprotection.com.au. They will be able to advise you on the regulations regarding fire safety and what the minimal requirements are with regards to fire protection equipment on the premises.
Of course, you always have the option to go above and beyond the minimum requirements and invest in additional fire safety and protection equipment. Not only does this greatly increase the fire safety levels in your premises, but as an employer, it demonstrates that you take the welfare of your employers seriously.
There is a long list of possible options, so we must stress that the ones we highlight are merely our suggestions and do not constitute any kind of definite regulatory advice or minimum legal requirement, both of which you must ascertain for yourself with regards to the commercial premises you are responsible for.
The type of property and the commercial activity which takes place will determine which types of fire extinguishers you need, and in particular what is necessary for the materials that are predominant inside those premises. As a minimum, you will have a red-banded water extinguisher which is suitable for most fires involving paper and wood.
You might choose to expand the types of fire extinguishers to include a Black Co2 extinguisher for electrical fires, and also the number of extinguishers, especially if the property has more than one room.
