A healthcare facility helipad is an integral part of the hospital and should not be treated as just a slab of concrete, according to an article on the Health Facilities Management.
In 1980, there were 50 helicopter emergency medical services aircraft in service in the United States; as of 2015 there were 1,015.
When an accident occurs, the investigation usually uncovers a series of smaller problems that eventually line up and are cause a potential catastrophe.
Facility managers must be cognizant of making sure the smaller issues do not line up and stay on guard to look for the signs. Parts of those signs are in and around the landing environment where the helicopter operates.
