How frequently should blankets be cleaned according to the requirements?

The correct choice aligns with the standards set by health and safety regulations, which prioritize maintaining hygiene in correctional facilities. Cleaning blankets once every three months ensures that they are free from pathogens, allergens, and other contaminants that could affect the health and well-being of inmates and staff alike. This frequency balances the need for cleanliness with practical considerations, allowing for effective hygiene without placing excessive demands on cleaning resources.

In comparison, options suggesting less frequent cleaning—like every six months or once a year—would not adequately address the risks associated with unclean bedding, particularly in a confined environment. Monthly cleaning may be impractical in terms of staffing and resources, potentially leading to inefficiencies in the overall maintenance schedule. Hence, cleaning blankets every three months strikes an appropriate balance between operational efficiency and the need for a safe and healthy living environment.
