The Health and Safety at Work (Hazardous Substances) Regulations 2017 governs the rules that the PCBU (Board, Proprietor and Principal) must follow to protect their school’s students, staff and visitors from being harmed by hazardous substances. Common hazardous substances at school include bleach, diesel, and aerosols to name a few. Schools need to have proper procedures in place to ensure the safety of their students, staff and any visitors.
