In a retreading company, a fire broke out at the end of the afternoon inside an 80 m² tire warehouse. The blaze could not be extinguished by the few employees still present onsite and spread, destroying more than half of a 4,400-m² building. A portion of the 30-strong workforce faced being laid off as a result. Some of the fire water supply remained within the site’s network, while another fraction entered the zone’s stormwater system and was discharged into a pond; no significant pollution was observed. An outside firm had been called in to complete welding work at the warehouse 45 min prior to the accident. No burning permit had been authorized and no special guidelines issued to the crew. Sworn agents were assigned to record these factual details
