Review of a U.S.Chemical Safety and Hazard Investigation Boar.d Investigation of an Ink Blending Operation Confined Vapor Cloud Explosion
On 22 November 2006, 2:46 AM Eastern Standard Time a terrible explosion rocked a residential community near the Massachusetts coast in the United States. This explosion came from an ink blending plant located in Danversport, Massachusetts, USA. Over 50 homes were damaged by the blast wave. No one was killed by the incident; however, 10 residents living nearby were injured. The plant was located in a densely populated residential area. Thus, the blast wave destroyed 24 homes, damaged 30 others, and ruined six businesses. Building windows were broken as far away as 3 km from the site. In the final analysis, worker error, leaving a steam supply valve open after the end of day, led to the explosion. The steam provided indirect energy needed to vaporize a flammable solvent contained in a large process ink blending tank. The vapor accumulated throughout the manufacturing building and exceeded the lower explosion limit concentration. An ignition source, probably located away from the preparation area, created a strong confined space vapor cloud explosion. The U.S. Chemical Safety Board investigation determined the direct cause, and further, the root causes including the lack of acceptable process safety practice by the company involved. With this knowledge, similar accidents can be prevented.
