Re-evaluation of lightning protection system to government building in Sarawak using simplified risk analysis and rolling sphere method

The lightning strike can be intimidating to living being and can cause of property damage and economic loss. Inadequate assessment of risk management will lead to poor design of lightning protection and risk mitigation which cause life hazard, structures damage and services interruption. Likewise, i...
