A nurse in an assisted-living facility is reinforcing teaching with staff members about preparing for an external chemical disaster. Which of the following instructions should the nurse include?

During an external chemical disaster, it is crucial to minimize the exposure of clients to hazardous substances. Moving clients to a room above ground level with few windows can help reduce the risk of exposure to the chemical and its fumes. This is because many hazardous chemicals tend to be denser than air and may settle closer to the ground. Choosing a room above ground level and with fewer windows can provide a safer environment. Turning on fans in the facility to circulate air can actually worsen the situation by spreading the chemical and its fumes throughout the facility, potentially exposing more individuals. Covering the electrical outlets with wet towels is not directly related to preparing for an external chemical disaster. It may be more relevant during a fire emergency to prevent the spread of flames, but not for chemical exposure. Opening the fireplace dampers in the day room can allow the entry of outside air and potentially introduce more of the hazardous substance into the facility.
