I will be updating this video soon, It was just pointed out to me that I say and show “1/2 divided by D” it should be “1/2 * D” for your trying to get 1/2 the distance of D for a not sprinkled building. for a sprinkled it would be 1/3. I will get this corrected soon. This video is on where doors you be located in a room where the occupied requires more than one door. Most occupancies that threshold is 49 people. Once that threshold is met two doors are required and a shout be remotely located from each other. Storage occupancies the threshold is 29, institutional occupancies most are around 10, hazard three people require you to have more than one door but with hazard on doors shall swing in the direction of travel.
