2. “The accident rate in schools is 10–50 times that of the chemical industry”.
NSTA, Guide to School Facilities, 1999

3. School Chemistry Labs—scene of some frightening accidents—expose 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.”
Tammy Webber, Associated Press, 2002

4. 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 team’s responsibilities?
