This Bachelor’s thesis was commissioned by L2 Paloturvallisuus Oy, a Jensen Hughes company. The purpose of the thesis was to draw up a unified and standardized system of visual markings for different elements of fire safety drawings used in Finland. At the time of writing, no such system exists, which leads to miscommunication between companies and authorities, creates delays, and negatively impact project costs.

The thesis is research-based and concentrates on the results of a professional survey conducted among Finnish fire safety experts. As an outcome of the thesis, a collection of element symbols was created. The chosen elements are suitable for use by groups of people with special needs (e.g. colour blindness), but are also distinguishable, intuitively understandable and easy to memorize.
