Three students from Alamo's Stone Valley Middle School were taken to area hospitals as a precaution after reporting they felt unwell during a science class activity Thursday morning, according to a school district spokeswoman.
The situation began just after 11 a.m. in a seventh- and eighth-grade combination forensic science class at the Miranda Avenue campus, according to Elizabeth Graswich, spokeswoman for the San Ramon Valley Unified School District.
The three students said they weren't feeling well while the class was performing a fingerprint experiment using approved materials, according to Graswich.
School officials called the San Ramon Valley Fire Protection District at 11:15 a.m. and the classroom was evacuated, according to fire officials. The room was inspected, and all 21 students in the class were examined by emergency personnel, Graswich said.
Inspectors found no evidence of hazardous materials in the classroom, according to Graswich, who said all students but one wore protective masks, goggles and gloves during the fingerprint activity. "It wasn't an issue with the experiment," she added.
Following the medical evaluations, three students were transported to area hospitals as a precaution, according to Graswich, who said the trio had returned to campus by 2:20 p.m. Thursday.
The cause of the students' ailments remains undetermined, she added.
Editor's note: To clarify, the SRVUSD reported on Thursday that all students were wearing protective masks, goggles and gloves during the fingerprint activity, but district spokeswoman Elizabeth Graswich said Friday evening that school officials subsequently learned one student wasn't wearing the protective items during the experiment.
