Quantitative Risk Analysis (QRA)

Contact information

Based on the results of a Quantitative Risk Analysis (QRA), it is determined whether the situation under consideration is feasible or can be granted a permit. This involves assessing compliance with applicable laws and regulations regarding external safety. A QRA models the relevant risks to the surrounding environment associated with activities involving hazardous substances. These risks may relate to storage and transshipment, production, or transport by rail, road, water, or pipelines. An exceptional QRA may be carried out for construction projects near airports or heliports or for the development of an airport or heliport.

What do we do?

We have the necessary expertise and calculation software to conduct a QRA. Companies subject to the External Safety Establishments Decree (Besluit externe veiligheid inrichtingen – Bevi) are required to perform a QRA if the fixed safety distances from the External Safety Establishments Regulation (Regeling externe veiligheid inrichtingen – Revi) do not apply.

The competent authority can act based on Article 4.2 of the Environmental Law Regulation (Regeling omgevingsrecht – Mor). For companies covered by the Activities Decree (type A and type B), the fixed safety distances apply where relevant. Peutz uses the following calculation tools to carry out a QRA:

  • Safeti-NL, which is prescribed by the Revi for non-categorical Bevi companies
  • RBMII, for the transport of hazardous substances by road, water, and rail
  • Carola, for the transport of natural gas through high-pressure gas pipelines
  • GEVERS, for aircraft and helicopter flight movements
  • Proteus II, for environmental risk analysis (MRA) related to the storage of (environmentally) hazardous substances and environmental risks for surface water

 

Fixed Safety Distances

The fixed safety distances from the Revi apply to so-called categorical establishments, namely:

  • PGS 15 establishments with storage of more than 10 tons of packaged hazardous substances
  • LPG filling stations
  • Cooling and freezing installations and heat pumps using ammonia as a refrigerant (usually ammonia refrigeration installations)
  • Establishments with more than 100 tons of group 2 fertilizers
