Biolanda Explosion: Prosecutor Investigates Causes Amid Propane-Contaminated Ground

The prosecutor has launched an investigation into the causes of the fatal explosion at the Biolanda factory in Trikala, which killed five workers. The tragedy followed a prolonged propane gas leak. Regional authorities had warned the company for years about violations—including improper distances between propane tanks, safety deficiencies, and an unregistered, undeclared basement. Costas Tsiggas, President of the Fire Service Officers’ Association, stated on ERT News (31.01.2025) that firefighting operations continue to prevent evidence contamination—due to persistent propane presence and explosion or ignition risks. The underground area housing propane pipelines remains saturated with liquid propane, posing ongoing hazards. A specialized arson investigation unit from the Hellenic Fire Service, under direct orders from its Chief, is on-site alongside prosecutors to ensure full transparency. Initial inspections revealed two external propane tanks connected via underground piping passing beneath the road into the facility. Soil contamination is estimated to extend dozens of meters under the asphalt—likely due to pipe corrosion. Central to the probe is the factory’s undeclared, undocumented basement, where workers reported a strong propane odor for some time. All company files have been seized; investigators are verifying compliance with legal safety requirements. Four punctures were found in the pipelines—identified as the leak source. Soil samples have been sent to the General Chemical Laboratory of the State to quantify leaked propane. The basement appears critical: propane seeped in, accumulated in low-lying layers, and likely ignited—triggering the blast.
