The caretaker checks the corridors regularly. He will inspect the safety, damages and maintenance issues. All escape routes, such as corridors and stairwells, must be free from obstruction. He also checks the escape route on other safety issues, for example inferior electricity cables, loose cables on the floor or highly flammable items such as flags or posters. The fire extinguishing resources and emergency lights must be clearly visible. For more information on safety see Safe housing.
