Final answer:
FEMA is the organization responsible for providing public advisories about mold after disasters. They work in collaboration with health experts to address human health risks and ensure the safety of the affected population.
Step-by-step explanation:
At a disaster, the organization that is responsible for deciding what advice to provide to the public about mold is the Federal Emergency Management Agency (FEMA). FEMA assists state and local governments during natural disasters and is tasked with coordinating various agencies to effectively manage the response. When it comes to public health advisories, such as the dangers of mold, FEMA would collaborate with health agencies and experts to disseminate the appropriate information and guidelines to ensure the public's safety.
Mold exposure can be harmful to human health, and guidance on how to deal with mold after a disaster is critical. It is FEMA's role to ensure that this information reaches those affected, including how to clean it up and prevent health risks associated with mold exposure.
