There are so many possible ignition sources that the only way to define the activation factor is to go through a review of possible fire sources, classified in the categories: main activities, heating systems, electrical installations, secondary activities and areas classified for explosion hazards.
Factor a is the sum of the relevant values of ai, which can be found in the next tables. Check on all applicable situations and a will be calculated automatically.
Defects on heating systems are well-known fire causes. The probability of a fire originated in the heating system depends on the type of heat transfer, the location of the heat generator and the type of fuel used.
Defects of electrical installations are well-known fire causes. The probability of a fire of electrical origin depends on the way the installation is installed and maintained. Regular checking of code compliance offers a good guarantee for a safe installation.
The presence or occasional escape of flammable vapours, gases or dusts is an additional source of fire.
Secondary activities are only taken into account when they create an additional number of fire sources, compared with the main activities. Welding e.g. will not be aggravating in a metalwork shop but must be taken into account in a carpentry shop.
X is total number of persons that will have to evacuate the compartment.
When "user defined" is selected, this value will be accepted; When a occupant load factor is given from the list, it will be multiplied by b x l.
For more details see on page Info A
E.g. in a hospital, it is clear that the minimal width of an exit unit is that of the beds which are used in the hospital.
Factor p corrects the evacuation time for the lack of mobility of the occupants and for other unfavourable circumstances..
Such as patients or elderly, handicapped or sleeping persons (in hotels)...
equivalent length of vertical travelling path
evacuation times of more than 900 seconds are problematic
If egress simulation software such as Exodus, Simulex, has been used to define the required safe egress time, the result can be entered here: the value entered will be used to calculate the evacuation time factor t
Factor c defines the value of the content of the compartment. It is calculated from is monetary value and replacement possibilities.
'Property' means as well the compartment itself as the goods in it, as its occupants.
currency used
The activity in the compartment will be hampered or interrupted by a fire. The added value / turnover ratio is a good reference for the sensitivity for business interruption.
