Abstract
This fire risk evaluation aims to assess the personal safety in the nursing home of Brunnsgården, Alingsås in the event of a fire. Brunnsgården consists of apartments for elderly people with dementia as well as assisted living in serviced apartments. Furthermore the building consists of a section with offices for the staff. This work is limited to a dementia section and a service section where all floors are identical. Moreover it is the residents' personal safety which is mainly considered in the report, as they are not expected to evacuate unassisted in the event of a fire.
Probable fire and evacuation scenarios were designed and based on these, simulations were made in the programs ERM, CFAST and FDS. The time to critical conditions in... (More)
This fire risk evaluation aims to assess the personal safety in the nursing home of Brunnsgården, Alingsås in the event of a fire. Brunnsgården consists of apartments for elderly people with dementia as well as assisted living in serviced apartments. Furthermore the building consists of a section with offices for the staff. This work is limited to a dementia section and a service section where all floors are identical. Moreover it is the residents' personal safety which is mainly considered in the report, as they are not expected to evacuate unassisted in the event of a fire.
Probable fire and evacuation scenarios were designed and based on these, simulations were made in the programs ERM, CFAST and FDS. The time to critical conditions in CFAST and FDS were compared with the time for evacuation from the evacuation scenarios in ERM. More so the results in the simulations were validated through performing sensitivity analysis. The fire safety is deemed to be not acceptable if critical conditions are achieved before everyone has evacuated.
This fire risk evaluation indicates a result in which the fire safety and the ability of evacuation of Brunnsgården nursing home is inadequate and in regard to that an acceptable personal safety is not achieved. The reason why personal safety is not achieved is mainly due to the production and distribution of smoke.
Since the fire safety is insufficient, measures are needed to improve this with the intention of reaching an acceptable level. Suggestion of measures are discussed and listed in the report as two kinds of measures; those that shall be implemented and those that should be implemented. One of the most significant measure, to prevent that critical conditions arise, is that the staff of Brunnsgården nursing home develop a well working fire prevention plan with clear directions of what to do in case of fire.
