WORKSHEET FOR ASSIGNING SPECIFIC STRUCTURES TO PERFORMANCE GROUPS
|RISK FACTORS||RELATIVE LEVEL OF RISK |
FOR SPECIFIC STRUCTURE
|Occupant Load. Maximum number of persons permitted to be in the structure or a portion of the structure.|
|Duration. Maximum length of time that the structure is significantly occupied.|
|Sleeping. Do people normally sleep in the building?|
|Occupant Familiarity. Are occupants expected to be familiar with the building layout and means of egress?|
|Occupant Vulnerability. What percentage of occupants, employees or visitors is considered to comprise members of a vulnerable population?|
|Dependent Relationships. Is there a significant percentage of occupants or visitors who are expected to have relationships that may delay egress from the building?|
|Nature of the Hazard. What is the nature of the hazard, and what are its impacts on the occupants, the structure and the contents?|
|Internal or External Hazard. Is the hazard likely to originate internally or externally or both?|
|LEVEL OF IMPORTANCE|
|Population. Are large numbers of people expected to be present?|
|Essential Facilities. Is the structure required for emergency response or post-disaster emergency treatment, utilities, communications or housing?|
|Damage Potential. Is significant risk of widespread and/or long-term injuries, deaths or damage possible from the failure of the structure?|
|Community Importance. Is the structure or its use largely responsible for economic stability or other important functions of the community?|
|Are the design performance levels adequate and appropriate for the specific structure?|
