 Evacuation time factor t  A - REF  A - V1  A - V2
  The evacuation time factor is calculated with the number of persons present in the compartment, their mobility, the dimensions of the building and the characteristics of the exit ways.
The total length of the evacuation path is calculated with the values of b, l, H+ or H-, which were already given.
INFO about X
Define X, the number of persons that can be present in the compartment.[1]
If this number is unknown, use the next table with occupant load factors based on NFPA 101. Be careful: local code requirements may use different occupant load factors.[2] persons/m˛

15. LOCAL CODE DEFINED OCCUPANT LOAD FACTOR 0,1 0,05 0,03
INFO about x
Define x, by counting all the exit units of the compartment according to legal and practical rules.
x is the number of exit units. The minimal width for an exit is 0.6 m (or 2 ft) unless law or practical conditions specify it otherwise. E.g. in a hospital, it is clear that the minimal width is that of the beds which are used in the hospital.
Consider some 20 cm (8 in) of lost width, i.e. a 80 cm (32 in) wide door has an effective width of 60 cm (24 in). A 2 m wide (80 in) corridor has an effective width of 1.80 m (72 in).
To define the value of x, look for each exit at the narrowest passage on the path, measure the width in cm or inches, deduct 20 cm or 8 in and divide the result by 60 cm or 24 in.
This will give the number of exit units per exit path. The sum of all the quotients gives the total number of exit units of the compartment.
In the example, the width of door A is relevant for exit path A, but for B it is the width C of the corridor.
Remark: large gates, sliding doors( except where specifically designed for emergency exit) and roller shutters shall not be considered as exit units!
INFO about p  A - REF  A - V1  A - V2
Persons that can move independently and are accustomed to the building features will be able to evacuate rapidly. People who need help or have to find their way to the exits will need more time.
Possibility D permits the calculation of a p factor for a mixed group 
A. Mobile and independent persons ( adults, workers) 1 10,0% 1 10,0% 1 60,0%
B. Mobile persons needing guidance ( pupils, visitors) 2 20,0% 2 50,0% 2 20,0%
C. Persons with limited mobility (patients, elderly, inmates) 8 70,0% 8 40,0% 8 20,0%
D. Calculated value for mixed group  (modify at info A) 6,1 100,0% 4,3 100,0% 2,6 100,0%
 INFO about K - Available and distinct exit paths
The number of AVAILABLE and DISTINCT exit paths is calculated in the following way: 
First, enter the number of exits that end in the open air, basically external doors and exterior stairways , but no ladders. 
The second step is to define the maximum capacity of all the exits together. This is done (automatically) by multiplying the number of exit units by 120.[3]
The third step is to divide this capacity by the number of occupants that are present. This quotient is the theoretical number of  "distinct" exit paths. The real number of distinct exit paths shall be not more than 4 (implying a 90° angle between them).  [4]
The number of the AVAILABLE and DISTINCT exit paths "K" is then the smallest value found in steps 1 and 3 . value of K
less than 1
Not allowed
less than 2 1

relative value of the content c1
Choose the value of c1 according to the possibility to replace the contents:
a. the contents can be easily replaced 0
b. the contents can difficulty be replaced[5] 0,1
c. the contents are unique.[6] 0,2
dependency factor d  A - REF  A - V1  A - V2
The activity in the compartment will be hampered or interrupted by a fire. The added value is a good reference for the sensitivity for business interruption.
The added value is the sum of the costs of personnel, financial costs, investments, and the company results. The turnover is the total yearly monetary value of all the revenues coming from the economic activity of the unit, which is considered.
The dependency factor d is the ratio of added value by turnover. The higher this ratio, the more sensitive is the activity. As a guideline the values for d can be estimated as follows:
a. High technology industry (e.g. aircraft) : 0.7 to 0.9 0,8 0,8 0,8
b. Precision industry (e.g. electronics) : 0.45 to 0.7 0,6 0,6 0,6
c. Manufacturing industry  : 0.25 to 0.45 0,35 0,35 0,35
d. Commercial companies, warehouses: 0.05 to 0.15 0,1 0,1 0,1
e. Administrative services: 0.8 0,8 0,8 0,8
f. Average for most businesses  0,3 0,3 0,3
g. USER DEFINED INPUT (at info A) 0,21 0,42 0,63

[1]
X is total number of persons that will have to evacuate the compartment.
[2]
NFPA 101 occupant load factors can be considered as maximum numbers, other codes may give use a different approach and numbers based on average occupant loads
[3]
The maximum capacity of an exit unit having a useful width of 60 cm ( e.g. a door of 80 cm ) is 120 persons per minute. If more people try to use this exit, they will be queuing to pass, which slows down the exit movement.
[4]
When all the exit units are needed to satisfy the evacuation requirements for the occupants , they shall be considered as a SINGLE useful exit path.
