When the construction of a building is complete, the owner (or sometimes the occupier) of the building is responsible for maintenance of features and measures essential for the safety and health of the occupants and those who use the building. The regular maintenance of the prescribed essential safety measures such as fire safety, exits and air flow will ensure that they will remain operational throughout the life of the building. Correct maintenance is the best way of ensuring that safety systems will operate reliably if an emergency arises. Otherwise a serious risk to the safety or health of the occupants or users may arise.
