- the degree of assistance required for occupant evacuation
- the number of occupants that require evacuation
- building construction and fire protection features to control the spread of fire
- level of staff training
- other actions required of staff within the Fire Safety Plan.
In the case of health care facilities, the higher the number of patients that require significant assistance for evacuation, the higher the demand on the staff. For purposes of medical services, it is generally true that the staff ratio increases are based on medical needs of the patients. Since there is some correlation between the degree of medical care and the degree of assistance during a fire emergency, this has traditionally provided some assurance that adequate staff are available for emergency response.
The variability within the above factors does not allow for a uniform ratio of supervisory staff to patients in all institutional facilities for purposes of emergency response (see also A2).
For instance, the Fire Safety Plan should include information identifying a number of probable fire scenarios based on building use and physical conditions. The scenarios should consider varying conditions throughout a 24 hour cycle. In an active care hospital, a probable scenario might involve evacuation of the operating rooms and recovery suites involving a large number of patients on life support or other critical medical treatment. Such suites are typically idle at night and thus a different scenario would need to be identified for the night shift. This may be a group of rooms or other suites where patients could reasonably be in jeopardy from a single fire source.
The staffing needs required to effect evacuation in each of the identified scenarios would need to be identified. This number, together with additional staff that may be required to carry out other duties under the Fire Safety Plan, would form the basis for the minimum number of staff required on each shift.
The probable scenarios may also be utilized by the owner to provide appropriate staff training. The Fire Safety Plan should take into account the staff training necessary to effect a proper response on each shift.
For instance, supervisory staff in a healthcare facility (B-2 occupancy) would typically be comprised of medical and nursing staff, attendants and building maintenance personnel. In high security institutions (B-1 occupancy) supervisory staff would consist mainly of guards and the warden's staff.
