Know the locations of all safety equipment in the lab: fire extinguishers, eye wash station, first aid box, fire blanket, fire exits.

  11. Accidents & Injuries Respond to emergencies sensibly and immediately! Inform a teacher if someone requires assistance. If chemicals are spilled on skin or in eyes, rinse with water for 20 minutes. If you break something or spill something, please inform a teacher immediately. Do NOT handle broken glass! If a fire starts, inform a staff member immediately – STOP… DROP… ROLL!!!
