providing first aid to non-University tenants in University-owned buildings, NFAOs should be prepared to render first aid if called upon to attend an emergency in a tenanted area. 3. FIRST AID FACILITIES 3.1 DETERMINING NUMBERS AND LOCATIONS OF FIRST AID KITS First aid kits should be located close to all work areas where there is a likely risk of injuries or illness occurring. No workstation should be more than 100 m from or one floor above or below a kit. First aid kits should be: easily accessible during the normal working hours of the area located in supervised areas -- to reduce opportunities for pilfering as kits should not be locked during normal working hours (although they must be capable of being locked) located if possible close to running water, toilets and a private area that can be used for treatment clearly visible and signposted with a standard safety sign consisting of a white cross on a green background. In many buildings a large central kit can be complemented with smaller portable kits that can easily be taken to the place where a person is injured. Portable kits may be kept at an NFAO's work location. Factors to be considered in determining the number and locations of first aid kits for a particular building include: the types of work performed and types of classes conducted in the building and the nature of hazards associated with those types of work and classes - laboratories and workshops typically require more frequent access
