Deadend and Common Path of Travel can be confusing. Hope this video can help with some of its understanding. Most of the time we have a choice of two ways to get out of a SPACE, and that is your common path of travel. From the most remote point in the building or space to a decision point to go to exit “A” or exit “B” to get out of the space, that is your decision point/common path of travel.
Understand that “commen path of travel” is not appiclible to hospitals. Hospitals have “suites” and “intervening rooms” other video cover those topics
