Science Safety in Texas Public Schools
developed by
Charles A. Dana Center
The University of Texas at Austin
“The accident rate in schools is 10–50 times that of the chemical industry”.
NSTA, Guide to School Facilities, 1999
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
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?
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?
Emergency Response System
• Establish an emergency response team
• Who should serve on the team?
• What are the team’s responsibilities?

Material Safety Data Sheets
Interpreting and Understanding Information on a MSDS
MSDS must:
• accompany chemicals
• conform to OSHA standards
• be maintained by school
• be written or electronic copies
• replaced within 30 days
• be readily available on request
The school district shall not permit use of chemical if it does not have an MSDS.
