Disaster investigations look at the emergency response that followed the incident, either the timing or actions taken to save human lives. There's more about the investigations calling for improved emergency preparedness; policies and technology development to prevent disasters such as the Hague Street Explosion (1850) which involved a faulty boiler (and other factors) and the Iroquois theater fire (1903) which led to changed theater building policies. 

Emergency response was addressed in IV. Global Health and Emergency Response. They discussed how organizations have different approaches to emergency response, either going for preparedness (WHO), immediate mitigation (humanitarian organizations), or management of global health threats (Gates Foundation). Short term solutions (emergency response) are much more common while preparedness-based solutions to prevent emergencies or minimize risks are often not funded and difficult to maintain due to the social/economic/ international issues that would need to be addressed.

Emergency response isn't explicitly addressed in the article, but in order to incorporate structural interventions into public health, emergency response would have to be improved as well. As the article states, there are many "diseases of poverty" and medical emergencies would be more common in those populations. Noting these trends can streamline medical response and help with providing education/ resources to prevent emergencies.

Violence against health care workers is the subject of the article so emergency medical response is addressed directly, but mostly within the context of humanitarian aid. 

Emergency response is addressed in the "Post-Disaster: Preventing and Treating Mental Health Conditions" section, with the debriefing done by emergency responders referenced. However, critical incident stress debriefing hasn't shown to be effective in the recovery process or preventing mental health disorders. Psychological first aid (PFA) is suggested as a post-disaster intervention, but it seems like a duty for mental health care providers, not emergency responders. 

The article describes the situation in post-Katrina New Orleans as one where trauma is constantly happening and more work is going into emergency response than recovery. Instead of construction workers, social workers and the like, the military was sent by the government for aid after Katrina.
