Lightning Risk Assessment Method for Explosion Hazardous Locations
1 Scope
This standard specifies the identification, calculation and evaluation of lightning risk in explosion hazard locations.
This standard applies to the production, processing, processing, storage of dangerous places of dangerous lightning risk assessment.

3 Lightning risk identification
3.1 Evaluation unit division
Should be based on the explosion of dangerous places where the explosion of the characteristics of the explosion, the location of the explosion and dangerous places after the explosion will cause it
The explosion of his facility is divided into multiple evaluation units by the following requirements.
- an electrical, electronic equipment suffered lightning, causing malfunctions may lead to secondary explosive accident, divided into an evaluation unit;
--- Lightning hit an explosion hazard object explosion may cause other isolated units occur when the explosion, divided into an evaluation list
For the concept of martyrdom, see Appendix A;
--- use of pipes, channel segments connected together equipment (or tank), should be divided into a unit.
The evaluation unit is shown in Table 1, and the evaluation unit is shown in Appendix B.
Table 1 List of evaluation units
Schematic explanation
Equipment 1 in the event of lightning strikes, will cause the device 2 occurred martyrdom, at this time two
The equipment should be classified as an evaluation unit
Equipment 1 and equipment 2 through a certain path to connect each other to transfer explosive substances or energy
Quantity, when the equipment 1 explosion occurred after the explosion, the explosive energy will be delivered to the device 2, and
So that the occurrence of blasting accident, this time the two equipment should be classified as an evaluation unit
Equipment 1 and equipment 2 of the explosion risk is through a certain electrical, electronic system control
System, then electrical, electronic system after lightning failure, may lead to equipment 1
Or equipment 2 explosion risk can not control, then the two devices and control system
The building of the building shall be classified as an evaluation unit
