Safety in the Elementary Science
Classroom and Laboratory
CAST ‘08
Fort Worth, Texas
Charles A. Dana Center
The University of Texas at Austin
The purpose of this seminar is to…
• understand safety laws, rules, and
regulations and their requirements
related to public schools.
• examine ways of improving safety in
science laboratories and classrooms.
• provide tools that can be used to solve
problems related to safety issues.
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
Where does it specify safety must be
taught in Texas’ classrooms?
Laboratory and field
investigations must be
part of the instructional
time in K–12 science
classes.

*
“The accident rate in schools is 10–
50 times that of the chemical
industry”.
NSTA, Guide to School Facilities, 1999
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?
Emergency Response System
• Establish an emergency response team.
• Determine should serve on the team.
• Define the team’s responsibilities.
After the accident is over
• Were the safety procedures adequate?
• 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?
Scenario I
• Read the scenario to
yourself.
• Discuss what happened
during the accident
with a person at your
table.
• Together, complete the
form on the reverse
side of the scenario.
• Decide who will be the
spokesperson.

Information on a MSDS
MSDS must:
• accompany chemicals
• conform to OSHA standards
• be maintained by school
• be written or electronic copies
