Our basic site plan is most popular among smaller businesses who have a single hazardous substance such as LPG. The site plan just includes an outline of the building in which the business is located along with the location and hazardous atmosphere of the substance that is being stored or used.  As our most simples option, this just includes everything smaller businesses need for their compliance certificates 

Complex site plans cover a range of drawings for bigger organizations and companies which store and use larger quantities of different hazardous substances. These can range from universities to manufacturers and usually include a lot more measurements and intricate details around the hazardous substances.  They can often require a site visit.
