Reefer container on ship sets off smoke alarm and was found to have overpressurized.
A Chinese company was shipping DCLBP - (DI-(2,4-chlorobenzoyl) peroxide). The ambient temperature was 40°C, and the SADT of the material is 60°C. It was incorrectly packed as mixed freight therefore may have become contaminated, and not possibly stored in the correct area to keep cool enough. The smoke detection system alerted the crew of the vessel, the hatch was closed and the CO2 system was activated. The material decomposed and over-pressurized and bulged the Reefer container. The decomposition left deposits which contained dioxins therefore a major decontamination exercise was needed.
- The material was incorrectly packed, thereby allowing possible containments and/or unwanted heat to start a runaway reaction, which led to a large pressure rise, and toxic by-products.
