Fans and lights are left on even when no one is in the classroom. Please switch them off. AC units and generators produce CO₂, which is harmful to students; reduce their use where possible. The guard is often absent at the back gate with no substitute, which is a security hazard. Assign a backup guard. Some benches are broken and left as they are, risking injury to someone unaware. Repair or cordon them off. Bus gates are kept open, creating pollution and security risks.
