If diseased, the carotid artery becomes narrowed or blocked and blood is unable to flow to the brain. The main cause of a stroke is a blockage in the carotid artery. Carotid artery disease is caused by the buildup of plaque in the arteries that supply blood to the brain.
Toilet Height. Whereas the height of a standard toilet is 17 inches or lower -- 14 1/2 inches is a common height -- the ADA guidelines mandate a distance between 17 and 19 inches from top of the seat to the floor on a handicap-accessible toilet. If the toilet is for use by children, the height must be from 11 to 17 inches. Many toilet manufacturers sell comfort models that conform to this height guideline, but if replacing your toilet isn't in your budget, you can increase the height of your standard toilet with an elevated seat.
In general, they are 8-9 feet wide. The ADA stall will be 5' wide, and add 3 feet for each additional stall. Also add 3 feet for urinals, and a minimum of 4 feet for each sink. An office that large, if it only has 1 bathroom for men and another for women, will probably have a minimum of 5 stalls/urinals and 2 sinks. In that case, you are looking at 9 x 25, or 225 sq. ft. Hope this helps.
