Answer: Gather resources and equipment to disperse within a community. And Meet with local law enforcement and community leaders
Explanation: An emergency and relief worker would need to help distribute resources to help citizens and would need to coordinate a plan of action. For example a relief worker would need to talk with community leaders to decide if evacuation is necessary and would talk to law enforcement to organize the evacuation. Lots of answers say use lab equipment to study causes of diseases but that isn't the job of an emergency and relief worker, that's the job of a pathologist. The focus of a relief worker is to get people away from danger and make sure they are well supplied.
