Lightning protection on a munition storage compound – Methodology for safety risk assessment
conference paper
Munition storage structures are equipped with lightning protection systems in order to prevent accidental initi-ation of munition due to lightning flash strikes. The effect of lightning strikes on munition storage sites is being studied extensively by the Dutch MoD, DNV, and TNO, and comprises site reviews, risk assessments, and numer-ical modelling of the electromagnetic fields inside a munition storage structure induced by a lightning flash strike and the munition response. This paper focuses on one specific part of the study: a method for a safety risk assessment (SRA) in order to assess the effectiveness and safety level of lightning protection measures and sys-tems on munition storage structures. The SRA-method is based on the international industry standard NEN-EN-IEC 62305 and can assess a wide variety of scenario’s and protection measures. It assesses two types of risk: risk of loss of human life (i.e. people present inside the structure) and risk of loss of assets (i.e. loss of munitions and damage to the structure). For the loss of human life, the risk is expressed as a probability of lethality per year for an individual (individual risk, IR). For the loss of assets, a qualitative risk matrix is used for the assessment. The combined assessment of both risk types allows for a full view on the risks and identification of required (if any) mitigation measures.
