Summary

Industrialization, urbanization, and climate change are all increasing the risk from Natech events in the world. Hazardous materials incidents present a significant threat to life and property, involve high values at risk and political sensitivities, cross jurisdictional boundaries, require numerous kinds and types of resources, entail complex strategies and tactics, may be affected by weather, and are relatively non-routine. They can thus be quite complex in and of themselves, even without the occurrence of natural hazards. Because of the confluence of natural disasters and industrial facilities involving hazardous substances, Natech events may pose additional challenges, including the compromise of response capabilities, multiple incidents occurring simultaneously, poor access, utility damage, and evacuation constraints and limitations.

As with all emergencies, a Natech response cannot be improvised. Improving Natech response capabilities requires enhanced preparedness efforts. Risk assessments should consider the impact of natural hazards in industrial facilities using or storing hazardous substances. This kind of analysis should allow planners to determine the specific capabilities and activities to respond to and recover from Natech incidents. Once the required capabilities have been determined, communities will need to determine the best way to build the additional capabilities required given funding limitations.

Emergency planning for Natech incidents should not be done in isolation but should be integrated in all-hazards, jurisdiction-wise planning. A hybrid approach, which combines planning based on scenario, function, and capabilities, is recommended. Collaborative planning helps individuals and organizations understand their roles, as well as the roles and contributions of other organizations, which ultimately leads to successful operations. Therefore, the first milestone in the planning process is to form a collaborative team, including facility owners or operators as early as possible in the process. Emergency planners are also advised to consider the potential of science and technology for improving preparedness efforts and response capabilities. Furthermore, exercise practitioners designing natural disaster exercises should consider including Natech events in scenarios to add realism and explore response capabilities.

In a Natech emergency, data are frequently incomplete and can even be contradictory, so responders should be as conservative as practicable so that they can protect both themselves and the public. Technical specialists for both hazardous materials and natural hazards should be integrated early in the incident command structure. Phasing the operation to protect resources, by keeping them out of the hazard zone, may be a useful strategy in some weather-related emergencies. Emergency managers should also consider how Natech evacuations may disrupt evacuations stemming from the need to protect people from a natural hazard. And first responders should consider a mix of offensive, defensive, and passive tactics.
