Line types in the past were often a series of dots and dashes to differentiate between hourly ratings and whether the wall was for smoke or fire.Ĭolor drawings have now become common, greatly improving the legibility of the drawings and reducing the likelihood of errors. Prior to the last decade, life safety drawings were printed as blueprints or black-and-white plots. However, because these dimensions don’t change once the walls and doors are in place, it is not necessary keep this information on the drawings.Īs the field continues to evolve, health facilities professionals are seeing some simple and practical changes that address accuracy.

Life safety drawings require a lot of information. (Drawings should be dated to reflect the last time they were reviewed or revised.) Any changes in the interim can simply be identified with a note on the drawings indicating the change as well as the date of the change.
