Due to the nature of schools and the close contact between students and staff in an enclosed environment, transmission of communicable diseases is always a risk. Schools always seek to reduce this risk through implementation of the best practices and strategies related to infection control. While personal hygiene is one of the most important factors in this effort, appropriate cleaning is also essential. Green cleaning can play an important role in this process and also help reduce the risks of chemical exposure. The information in this section provides policies, guidance, training, and approved products related to green cleaning provided by the New York State Office of General Services (OGS).
