Introduction
In-depth interpretation of the risk assessment method for lightning strikes in explosive hazardous places
1. Background and significance of standard formulation
GB/T32936-2016 "Risk Assessment Method for Lightning Strike in Explosive Hazardous Places" is to standardize lightning protection in explosive hazardous places and reduce the risk of explosion accidents caused by lightning strikes. With the rapid development of industrial production, the number and complexity of explosive hazardous places are increasing, and lightning strikes have become a major safety hazard in such places.
2. Comparative analysis of standard frameworks
| Standard dimensions | GB/T32936-2016 | GB/T21714.2-2008 | GB50057-2010 |
|---|---|---|---|
| Scope of application | Lightning risk assessment in explosion-hazardous areas | Risk management of lightning protection of buildings | Design specifications for lightning protection of buildings |
| Core contents | Lightning risk identification, calculation and evaluation methods | Risk management and casualty protection | Classification and design requirements for lightning protection buildings |
| Technical indicators | Calculation of annual lightning strike density, lightning strike risk value, etc. | Loss rate model and protection measures | Lightning protection level classification and rolling ball method formula |
3. Implementation suggestions
Case analysis:Lightning strike risk assessment and protection measures for a petrochemical storage tank area
1. According to GB/T32936-2016, the storage tank area is divided into multiple evaluation units.
2. The annual lightning strike density calculation formula (Ng=0.1×Td) is used to evaluate the regional lightning activity level.
3. Use formula (2) and formula (3) to calculate the lightning strike risk value and safety degree respectively, and determine the key protection areas.
4. Select corresponding protective measures according to the safety L value to ensure that the requirements of the GB/T21714 series standards are met.
