Final Safety Reminder
Safety is a shared responsibility. While Classgrid provides educational resources and safety
information, it is your responsibility to follow proper laboratory protocols, use appropriate safety
equipment, and work under qualified supervision when conducting any experiments.
Always prioritize your safety and the safety of those around you. When in doubt, consult with
qualified professionals and refer to official safety documentation.
