There is an increasing trend globally of fire incidents as a direct consequence of battery failures[1-6], but a dearth of reporting in medical literature regarding injuries associated with primary lithium cell explosions. We present the case of an electrical engineer referred to the burns team as a chemical burn secondary to a D-cell lithium battery explosion. Initial assessment revealed an entry wound on the anteromedial thigh leaking contaminated fluid. Orthogonal X-rays demonstrated the battery casing lodged within the posterior thigh compartment. The wound was managed similar to that of a ballistic injury with staged debridement, washout and delayed primary closure. This is the first reported case of a lithium-thionyl chloride battery explosion causing injury. The case highlights various issues for attending teams, including appropriate first aid for chemical burns, consideration of significant soft tissue trauma deep to seemingly innocuous wounds and safeguarding concerns surrounding domestic explosive devices. © BMJ Publishing Group Limited 2024.
