An Army Bomb Disposal Team has made safe an unstable chemical found at a secondary school in Co Limerick.
Coláiste Iosaef in Kilmallock was evacuated at around 11.30am following the discovery of a hazardous substance in the science laboratory during a routine audit of chemicals.
The bomb disposal team carried out a controlled explosion on the unstable chemical, Dinitrophenylhydrazine.
Dinitrophenylhydrazine is a chemical re-agent and is routinely used in laboratories but can crystallise and become unstable over time.
All staff and pupils were sent home this morning.
