FRAME is developed on six basic ideas:

• 1. In an adequately protected building there is a good balance between the threat and the available protection.

• 2. The possible severity of the fire can be calculated with of a number of influence factors.

• 3. The acceptability of a fire risk is lower when the exposure level is higher.
• 4. The level of fire protection can also be expressed as a combination of values for the different protection techniques.

• 5. The risk assessment in a building is made separately for the property (building and content), for the occupants and for the activities in it.

• 6. A separate calculation shall be made for each compartment.

DEFINITIONS AND BASIC FORMULAS :

1. The Fire Risk R for the building and its content is defined as the quotient of the Potential Risk P by the Acceptance Level A and the Protection Level D:

R = P / (A * D)

The Potential Risk P is defined as the product of the fire load factor q, the spread factor i, the area factor g, the level factor e, the venting factor v, and the access factor z:
P=q*i*g*e*v*z
The Acceptance Level A is defined as the maximum value 1.6 minus the activation factor a, the evacuation time factor t, and the value factor c:
A = 1.6 - a - t - c
The Protection Level D is defined as the product of the water supply factor W, the normal protection factor N, the special protection factor S and the fire resistance factor F:
D=W*N*S*F
2. The Fire Risk R1 for the occupants is defined as the quotient of the Potential Risk P1 by the Acceptance Level A1 and the Protection Level D1 :
R1 = P1/ (A1 * D1)
The Potential Risk P1 is defined as the product of the fire load factor q, the spread factor i, the level factor e, the venting factor v, and the access factor z:
P1 = q * i * e * v * z
The Acceptance Level A1 is defined as the maximum value 1.6 minus the activation factor a, the evacuation time factor t, and the environment factor r:
A1 = 1.6 - a - t - r
The Protection Level D1 is defined as the product of the normal protection factor N and the escape factor U:
D1 = N * U
3. The Fire Risk R2 for the activities is defined as the quotient of the Potential Risk P2 by the Acceptance Level A2 and the Protection Level D2:
R2 = P2 / ( A2 * D2)
The Potential Risk P2 is defined as the product of the spread factor i, the area factor g, the level factor e, the venting factor v, and the access factor z:
P2 = i * g * e * v * z
The Acceptance Level A2 is defined as the maximum value 1.6 minus the activation factor a, the value factor c, the dependency factor d:
A2 = 1.6 - a - c - d
The Protection Level D2 is defined as the product of the water supply factor W, the normal protection factor N, the special protection factor S and the salvage factor Y:
D2 = W * N * S * Y
For an adequately protected compartment the values of the Risks R, R1 and R2 are equal to or below 1.
