A fire safety plan can be prepared by everyone, however, it is important to be familiar with fire protection systems and equipment installed in a building. Fire protection is a specific field with a specific nomenclature, and some engineering knowledge is required. The person also needs to be familiar with a drawing software to prepare floor plans of the building.
Some fire departments offer fire safety plan templates. You can download them from our Services page.
However, if "time is money" for you, I would not recommend you to spend time preparing your plan. I've met many people who spend days preparing their plans and they were still not accepted by fire inspectors.
