7 USING FIRE RISK ASSESSMENTS TO IMPLEMENT A CODE/STANDARD Discontinue use of Hospital Nursing Home Other Health Care Facility Use Risk Categories instead Risk assessment is NOT optional

8 RISK CATEGORIES NFPA 99, Health Care Facilities Code, Section 4.1 states: Building systems in health care facilities shall be designed to meet system Category 1 through Category 4 requirements

9 RISK ASSESSMENT Categories determined by following and documenting a defined risk assessment procedure

10 RISK CATEGORY 1 DEFINITION Facility systems in which failure of such equipment or system is likely to cause major injury or death of patients or caregivers shall be designed to meet system Category 1 requirements as defined in this code

or death of patients or caregivers shall be designed to meet

11 RISK CATEGORIES In risk category definitions there is the assumption that there is no intervention from caregiver or others Different categories of systems can exist in the same occupancy Gas system in doctor s office = Category 3; gas system in ER = Category 1 HVAC (cooling tower) at Seattle hospital = Category 3 but a Category 1 gas system

the same occupancy Gas system in doctor s office = Category 3; gas system in ER =

15 NFPA Antifreeze systems with concentrations in excess of 30% propylene glycol and 38% glycerine shall be permitted based upon an approved deterministic risk assessment prepared by a qualified person approved by the AHJ. Annex note with references to test data and factors to be considered

approved deterministic risk assessment prepared by a qualified person

16 NFPA Alternative fire pump non flow test frequency when: The reliability/risk analysis shows that a different test frequency is appropriate The reliability/risk analysis is approved by the authority having jurisdiction. Annex note refers to the FPRF Report

17 NFPA Assessment of Internal Condition of Piping Where an assessment frequency has been established by an approved risk analysis, the assessment shall be performed at a frequency determined by the approved risk analysis.

approved risk analysis, the assessment shall be

18 QUESTIONS Are the developers of the codes/standards serious about allowing risk assessments as an alternative to prescriptive criteria? Or, is this merely an attempt to achieve consensus? Are the users of the codes/standards adequately prepared to perform the intended risk assessment? Or, if a quantitative risk assessment is required do we have the necessary data? SFPE Guide is a resource document for the methodology

Are the users of the codes/standards adequately prepared to perform the intended risk assessment?

19 QUESTIONS Are the AHJ s prepared to accept the use of risk assessments? Or, will the approach be that as long as it is determined to be equivalent it is okay? NFPA 531 is a resource document Is our litigious society willing to accept properly prepared risk assessments? Or, will the bar always be the prescriptive requirements?

okay? NFPA 531 is a resource document Is our litigious society willing to accept

20 QUESTIONS As the Standards Development Organization, what role does NFPA have in providing training and guidance on performing the risk assessments if: the Committee has defined a specific methodology? the Committee has not defined a specific methodology?
