EXPLANATION OF TERMS AS PER CLAUSE 4 OF IEC 62305-2:
3.1
Damage and Loss
3.1.1 Source of Damage The lightning current is the primary source of damage. The following sources are distinguished by the strike attachment point as per table-1 of IEC 62305-2. S1: Flash to a Structure S2: Flash near a structure S3: Flashes to a service S4: Flashes near a service

Type of damage
A lightning flash may cause damage depending on the characteristics of the object to be protected. Some of the most important characteristics are: type of construction, contents and application, type of service and protection measures provided. For practical application of this risk assessment, it is useful to distinguish between three basic types of damage which can appear as the consequence of lightning flashes. They D1: Injury to living beings D2: Physical damage D3: Failure of electrical and electronic systems
3.2.1 Type of loss Each type of damage, alone or in combination with others, may produce a different consequential loss in the object to be protected. The type of loss that may occur depends on the characteristics of the objects itself and its content. The following types of loss will be taken into account; L1: Loss of human life L2: Loss of service to the public L3: Loss of cultural heritage L4: Loss of economic value (Structure and its content)
3.3
Risk and Risk Components
3.3.1 Risk The Risk R is the value of a probable average annual loss. For each type of loss which may appear in a structure or in a service, the relevant risk will be evaluated. The risks to be evaluated in a structure may be as follows: R1: Risk of loss of human life R2: Risk of loss of service to the public R3: Risk of loss of cultural heritage R4: Risk of loss of economic value

The evaluate risks, R, the relevant risk components will be defined and calculated. For the D & B buildings, in general the risk component R1, R2 & R4 is considered for all the buildings. Risk R3 (cultural heritage) is to be considered only for the Mosque. Each risk, R, is the sum of risk components. When calculating a risk, the risk components may be grouped according to the source of damage and type of damage.
3.3.2 Composition of Risk Components Related to a Structure as Per Clause 4.3 of IEC 62305-2
Risk components to be considered for each type of loss in a structure are listed below: R1: Risk of loss of human life: R1 = RA + RB + RC + RM + RU + RV + RW + RZ RC, RM, RW and RZ are not applicable as they are applicable only for structures with risk of explosion and for hospitals with life-saving electrical equipment or other structures when failure of internal systems immediately endangers human life. RU, RV and RW are the risk components to be considered due to the flashes to a line connected to the structure. In this case, all D & B buildings are is not connected to overhead line and only connected through cables, thus the risk components are not applicable. Therefore, R1 = RA + RB R2: Risk of loss of service to the public: R2 = RB + RC + RM + RV + RW + RZ = RB + RC + RM R3: Risk of loss of cultural heritage: R3 = RB + RV R4: Risk of loss of economic value: R4 = RB + RC + RM + RV + RW + RZ = RB + RC + RM The above risk components equations corresponding to each type of loss are based on Page51, Table-3 of IEC 62305-2

Page 6 of 97
RA: Component related to injury to living beings caused by touch and step voltages in the zones up to 3 m outside the structure. Loss of type L1 and, in the case of Loss of type L1 and, in the case of structures holding livestock, loss of type L4 with possible loss of animals may also arise. RB: Component related to Physical damage caused by dangerous sparking inside the structure triggering fire or explosion, which may also endanger the environment. All type of loss (L1, L2, L3 and L4) may arise. RC: Component related to failure of internal systems caused by LEMP (Lightning Electromagnetic Impulse). Loss of type L2 and L4 could occur in all cases along with type L1 in the case of structures with risk of explosion and hospitals or other structures where failure of internal system immediately endangers human life.
3.3.4 Risk Components For A Structure Due To Flashes Near The Structure
RM: Component related to failure of internal systems caused by LEMP (Lightning Electromagnetic impulse). Loss of type L2 and L4 could occur in all cases along with type L1 in case of structures with risk of explosion and hospitals or other structures where failure of internal system immediately endangers human life.
4. RISK MANAGEMENT: 4.1
Basic Procedure:
The decision to protect a structure or a service against lightning, as well as the protection of selection of protection measures, will be performed according to IEC 62305-2. The following procedure will be applied: Identification of the object to be protected and its characteristics Identification of all the types of loss in the object and the relevant corresponding risk R (R1 to R4) Evaluation of risk R for each type of loss (R1 to R4) Evaluation of need of protection, by comparison of risk R1, R2 and R3 for a structure with the tolerable risk RT Evaluation of cost effectiveness of protection by comparison of the costs of total loss with and without protection measures. In this case, the assessment of components of risk R4 for a structure will be performed in order to evaluate such costs.

Page 7 of 97
Tolerable Risk (RT)
As per Clause 5.4 of IEC 62305-2 Table-7 Page-59, Tolerable risk for Loss of human life or permanent injuries is 10-5. Tolerable risk for Loss of service to the public is 10-3 Tolerable risk for Loss of cultural heritage is 10-3 Tolerable risk for Loss of economic value is 10-3
4.3
Specific Procedure to Evaluate the Need of Protection
As per IEC 62305-1, the following risks will be considered in the evaluation of the need of protection against lightning for a structure: Risks R1, R2 and R3 Besides the need for lightning protection for the object to be protected, it may be useful to evaluate the economic benefits of providing protection measures in order to reduce the economic loss L4. In this case, the risk R4 of loss of economic values will be assessed. The assessment risk R4 allows the evaluation of the cost of the economic loss with and without the adopted protection measures. For each risk to be considered, the following steps will be taken: Identification of the components RX which make up the risk, Calculation of the identified risk components RX, Calculation of the total risk R, Comparison of the risk R with tolerable value RT. If R ≤ RT, lightning protection is not necessary. If R > RT protection measures will be adopted in order to reduce R ≤ RT for all risks to which the object is subjected. In D & B buildings, protection level shall be level four, therefore level four protection will be considered and all risks will be calculated based on that consideration and it will be proved that all the calculated risks are less than the tolerable risks values. Attachment- 3 -10 shows the calculation report and the results.

Protect Line 1 at its entrance to the structure with a enhanced equipotential bonding SPD (rated to ISPD above) in accordance with BS EN 62305-3 NOTE: Where SPDs are required but an LPS is not (ISPD = 0), protect overhead lines with Type 1 SPDs (mains 12.5kA 10/350µs, data/telecom 2.5kA 10/350µs), protect underground lines with overvoltage or Type 2 SPDs (tested with an 8/20 µs waveform)
Protect all internal systems connected to Line 1 with a coordinated set of enhanced SPDs in accordance with BS EN 62305-4 Line 2
Protect Line 2 at its entrance to the structure with a enhanced equipotential bonding SPD (rated to ISPD above) in accordance with BS EN 62305-3 NOTE: Where SPDs are required but an LPS is not (ISPD = 0), protect overhead lines with Type 1 SPDs (mains 12.5kA 10/350µs, data/telecom 2.5kA 10/350µs), protect underground lines with overvoltage or Type 2 SPDs (tested with an 8/20 µs waveform)

NOTE: The worst case surge that could be expected on a two-wire telephone or data line is 2.5kA (10/350 µs) per line (Category D test to BS EN 61643-21) to earth or 5 kA (10/350 µs) per pair.
Line 1
Protect Line 1 at its entrance to the structure with a standard equipotential bonding SPD (rated to ISPD above) in accordance with BS EN 62305-3 NOTE: Where SPDs are required but an LPS is not (ISPD = 0), protect overhead lines with Type 1 SPDs (mains 12.5kA 10/350µs, data/telecom 2.5kA 10/350µs), protect underground lines with overvoltage or Type 2 SPDs (tested with an 8/20 µs waveform)
