Brandteknisk riskvärdering av Hotell Nissastigen
(2018) VBRN70 20181Division of Fire Safety Engineering
- Abstract
- In the following report, a fire safety evaluation of Hotel Nissastigen in central Gislaved is presented. The building itself consists of five floors, whereof two are cellar and attic. Beyond the usual hotel business, Nissastigen both offers a place to eat at their restaurant and room for conferences, as well as acting as a gathering point for tourists, thus making it vital for the local economy.
The purpose with this report is to perform a fire safety evaluation of Hotel Nissastigen and find out whether the building can be evacuated safely in case of a fire or not. The scope of the evaluation is limited to personal safety, hence disregarding damages to property, environment or other.

The building itself consists of five floors, whereof two are cellar and attic. Beyond the usual hotel business, Nissastigen both offers a place to eat at their restaurant and room for conferences, as well as acting as a gathering point for tourists, thus making it vital for the local economy.
The purpose with this report is to perform a fire safety evaluation of Hotel Nissastigen and find out whether the building can be evacuated safely in case of a fire or not. The scope of the evaluation is limited to personal safety, hence disregarding damages to property, environment or other.
After an initial general risk analysis, a selection from the ten fire scenarios was made to determine which three scenarios was to be further analyzed with simulations using FDS and Pathfinder, along with hand-made calculations. To evaluate personal safety, critical values for smoke layer height, temperature and visibility were set. Relevant safety measures are proposed along with a final evaluation and conclusion of the building’s fire protection.
The conclusion drawn is that the fire protection of Hotel Nissastigen is partly acceptable. The personal safety is heavily dependent on factors whose functionality cannot be guaranteed, such as the systematic inspection of whether the emergency exits are functional or not and how effective the magnetically controlled doors are at reducing smoke spread. A selection of the safety measure proposals is presented below.
Safety measure proposals regarding evacuation
* Installation of two-way communication systems and creation of evacuation instructions intended for people with movement disabilities in case of fire
* An update of evacuation plans since the current plans does not accord with current doors and hallways
* Better routines for ensuring that emergency exits are functional
* Widening of emergency exit, or addition of an extra staircase, on the second floor to ease the flow of people out of the large conference room
Safety measure proposals regarding fire cell boundaries
* Replacing the magnetically controlled doors with airtight doors (EI 30-SmC)
* Installation of automatic door closers on doors that make up fire cells, to ensure the integrity of the fire cells
* Sealing of every lead-through made throughout the building (Less)
