An LP gas truck explosion involving a unit owned by Tomza Gas Titanium occurred in the Las Granjas neighborhood of Cuernavaca, Morelos. The incident caused at least 22 injuries and damaged 34 homes, with three buildings declared uninhabitable. While the driver fled the scene, authorities began investigating the cause of the fuel leak, with preliminary reports suggesting the blast may have been caused by a leak resulting from a vehicle impact, possibly due to hitting a pothole or speed bump at high speed.

Following the blast, the Morelos State Civil Protection Coordination initiated administrative procedures that could lead to sanctions or the permanent closure of the company. However, Tomza has continued to operate without sanctions as investigations remain ongoing. The State Attorney General's Office (FGE) has received a growing number of formal complaints, with reports indicating the total has exceeded 130 from those affected by the blast.

The investigation intensified following the death of Viviana Aguilar Zendejas at Hospital La Raza, who succumbed to severe burns after reportedly using her body to protect her six-year-old daughter. Authorities have reclassified the legal investigation to reflect the fatality and have linked the vehicle involved to Transportadora Silza, a subsidiary of the fuel conglomerate Grupo Tomza.

In response, federal deputy Magda Erika Salgado Ponce has called for investigations into safety protocols, vehicle mechanical conditions, and permits. President Claudia Sheinbaum has also indicated that the company could face new sanctions if safety violations are proven. The incident has contributed to increased scrutiny of LP gas operations across Mexico.
