Instead of OSHA keeping watch over the safety of first responders, the Department of Homeland Security (DHS) and the Federal Emergency Management Agency (FEMA) may wind up responsible for enforcing health and safety regulations.
A legal guardian is a person who has the legal authority (and the corresponding duty) to care for the personal and property interests of another person, called a ward.
The term is most often applied to a person who is responsible for the care and management of an infant, which in legal terms is a person below the age of majority. Thus, children who have not reached adulthood (usually age 18 or 21) must, with some exceptions, have a legal guardian.
