How must all outside openings of the prep room be maintained?

The requirement to cover all outside openings of the prep room with screens ensures that the environment is safe and sanitary for handling bodies and conducting preparation activities. This practice prevents the entry of unwanted insects, dust, and other contaminants that could compromise the cleanliness of the prep area, which is vital in maintaining public health and upholding the dignity of the deceased.

Maintaining screens allows for adequate airflow while also acting as a barrier against potential sources of contamination. This dual role is essential in a funeral service setting where hygiene and respect for the deceased are paramount. Proper ventilation is essential; however, it must be balanced with the need for a controlled and clean environment. Other methods such as sealing openings completely or relying solely on ventilation fans may not adequately protect against external pollutants, which is why the correct approach is to use screens for outside openings.
