Another aspect of design in a healthcare building is safety. Having surfaces that are easy to decontaminate and readily-available washing stations with hand rubs and alcohol are must-haves. In order to prevent the spread of germs, sickness, and infectious diseases, filtration and ventilation systems should be a top priority. The strategic placement of assistive and protective devices, such as defibrillators and fire extinguishers, is paramount in effective healthcare design and construction. The safety of the occupants in the building cannot be overlooked.
