Outline

     What is the problem?

     Approach to this task

     Evaluation of performance
     level

     Direction on changes

33
What is the problem?
• Care to people moved
     - away from larger institutional facilities
     - towards smaller residential-type
       accommodations
     - Within their community
• Providing affordable care in a
  family-type environment
• Not based on
     - The ambulatory capability of
       occupants that may change over time
     - Protect in place methods (sprinklers)

34
Approach to the Task
              Construction, Industry and Public

                                                  Standing Committees
     PTPACC               CCBFC                   • Fire Protection (SC-FP)

                       Joint Task Group

35
Approach to the Task

Mandate
 Review Code change request received
 Conduct a literature review
 Analyze Code and proposal performance level
 Recommend changes to the model Codes (if required)
 Report back to parent standing committees

36
Approach to the Task

     Consideration was given to what other jurisdiction are
     doing and the research

     Principal goal is to get occupants out and not rely on
     protection in place methods

     Developed a series of requirements that allows a home-
     type care facility to be built under strict conditions that
     offer an affordable lodging in a safe environment

37
Approach to the Task

38
Evaluation of performance level

     Dr. S. Gwynne (NRC)

     Objective of work:

 To establish internal horizontal travel distance limits for
    future single level designs that enable equivalent
   evacuation performance to current Code compliant
                          designs.

39
Evaluation of performance level

                                  Produced by
                                  S. Gwynne

40
Evaluation of performance level,
current Code compliance

41
Evaluation of performance level,
current Code compliance

     Code compliant design (S. Gwynne)
                Evacuation time in seconds

42
Evaluation of performance level,
future design

     Results aggregated across scenarios (S. Gwynne)

              Maximum internal travel distance
                (evacuation time: 275 sec.)

43
Evaluation of performance level,
future design

     Across scenarios:

      - Staff ratio of 1:1 

      - Staff ratio of 1:2 (Sensitive)

      - Staff ratios of 1:3 to 1:4 

44
Direction on Changes

     New Group B, Division 4 occupancy (home-type care
     occupancy)
      - Home-type care occupancy means the occupancy or use
        of a single housekeeping building where care is provided
        to residents and may include the living space of the care
        giver and his family.

     Construction requirements under Part 9

45
Direction on Changes

     Option 1 (status quo)
      - Sleeping accommodation up to 10 (ambulatory occupants)
      - Can be considered Group C in Part 9

     Option 2, protect in place methods (modified)
      - Sleeping accommodation up to 10 (no specifics on mobility)
      - Sprinklered - NFPA 13D

     Option 3, enhance evacuation (new)
      - Sleeping accommodation up to 4 (no specifics on mobility)
      - Enhance evacuation and detection

46
Direction on Changes

Option 3A (Typical new construction)

47
No more than 4 people
           receiving care
     (no specifics on mobility)
