School and medical officials have been ordered to look into the mercury spill at Manila Science High School (MSHS) that has led to the suspension of classes since Thursday, the Department of Education said.
"Based on the initial account of MSHS principal Eva Nacion to SDS Cabral, 60 (milliliters) of mercury from a Charles' Law apparatus spilled on the corridor of the laboratory room last March 18, prompting the science teachers, on their own capacity, to immediately clean the spill," the DepEd said in a statement.
The area has since been isolated, and an industrial waste disposal specialist was hired to complete the cleanup, the DepEd added.
Even though the two teachers and the two students who were exposed to the chemical have not manifested signs of possible health complications, education officials will still look into possible violations.
"Department Order No. 48, or the Observance of Safety Measures in Science Laboratories, has set strict guidelines on the safe handling, storage, and disposal of chemicals in schools and the immediate reporting of all accidents whether or not these result in an injury," the DepEd's statement read.
Proper authorities, such as the departments of health, environment, and science and technology must be informed at once for expert management of the emergency situation, the department added.
Officials have yet to announce when classes at the MSHS will resume.
