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.
[3]
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.
[4]
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.
[5]
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.
[6]
The presence or occasional escape of flammable vapours, gases or dusts is an additional source of fire.
[7]
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.
[8]
X is total number of persons that will have to evacuate the compartment.
[9]
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.
[10]
For more details see on page Info A
[11]
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.
[12]
It is not allowed to have more than 120 persons per exit unit. You shall not enter a higher number. Increase first the value of x (the number of exit units).
[13]
Factor p corrects the evacuation time for the lack of mobility of the occupants and for other unfavourable circumstances..
[14]
Such as patients or elderly, handicapped or sleeping persons (in hotels)...
[15]
equivalent length of vertical travelling path
[16]
evacuation times of more than 900 seconds are problematic
[17]
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
[18]
Factor c defines the value of the content of the compartment. It is calculated from is monetary value and replacement possibilities.
[19]
'Property' means as well the compartment itself as the goods in it, as its occupants.

Currency used
[21]
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.
