School Chemistry Labsscene of some frightening
accidentsexpose lack of safety oversight
In a blinding flash, the routine high school
chemistry experiment turned to chaos. An
alcohol-fueled fireball shot into the classroom,
searing the skin of three junior honor students
in the front row.

If an accident occurs in a laboratory

• How should you respond if a student is injured?
• Who notifies the principal?
• Who alerts the school nurse?
• Do you include custodial staff?
• Who notifies the parents?
• Who supervises the other students?
• What happens if you are injured?

5
After the accident is over

• Were the safety procedures reviewed?
• Did you have the safety equipment to respond
  appropriately?
• Did you have proper first-aid training to respond
  appropriately?
• Were accident reports completed and filed?
• Were steps taken to prevent similar accidents?

6
Emergency Response System

• Establish an emergency response team
• Who should serve on the team?
• What are the teams responsibilities?

How could the teacher respond? What safety
equipment was needed? What were the safety
measures before the accident? What should
happen after the accident? Could the accident
have been prevented? Could you respond
appropriately if this happened in your room?
