Bomb disposal teams have detonated chemicals suspected to be unstable in seven English schools, sparking concern among local residents over safety precautions. The potentially hazardous substance, 2,4-dinitrophenylhydrazine (2,4-DNPH), is commonly used in A-level chemistry lessons but can become volatile if not stored correctly.
The science advisory body Cleapss issued a warning to schools last week about the correct storage procedures for 2,4-DNPH, prompting schools to inspect their chemical stocks and contact authorities with concerns. Dr David Kinnison, safety adviser, said on BBC Radio 4's Today programme that while the material is potentially hazardous when stored improperly, schools summoning bomb squads were justified, stating it was "best to be safe rather than sorry."
The Department for Education confirmed that incidents involving 2,4-DNPH at a small number of schools prompted the warning. A spokesperson noted that the chemical is safe when stored correctly and on-site explosions are preferable to transporting hazardous materials.
Reports indicate that affected schools include Nottingham Academy, Ryde School with Upper Chine and the Isle of Wight College (both on the Isle of Wight), St Alban's Catholic High School in Ipswich, Thomas Adams School in Wem, De Montfort School in Evesham, and Turton School in Bolton. Local residents expressed frustration over not receiving prior warning about the explosions, with some schools citing a lack of time to inform neighbours due to the urgency of the situation.
At St Alban's Catholic High School, an army bomb disposal team detonated the suspected hazardous material on the playing fields during school hours, causing an unexpectedly loud bang. Controlled blasts were also reported at two schools and a college in Carmarthenshire, Wales.
