A jury recorded a narrative verdict at an inquest into the death of a chemical worker who died after being involved in an explosion at a site in Stallingborough.
It follows the conclusion of an inquest into the death of Paul Doyley, from Immingham, who died after a blast caused by leaking titanium tetrachloride fumes at Stallingborough's Cristal Global site, formerly known as Millennium Chemicals, on March 5, 2010.
Mr Doyley, who was aged 48 at the time, received treatment for chemical burns and inhalation of toxic fumes at a specialist burns unit at Wakefield's Pinderfields Hospital following the explosion, but later died on March 18.
The jury returned a narrative verdict following the three-day inquest and there were no recommendations from the coroner.
They decided how the incident was the result of an uncontrolled chemical reaction which led to the over-pressurisation and rupturing of a vessel.
This rupture led to the release of the vessel's highly toxic and corrosive contents, which enveloped Mr Doyley in a vapour cloud.
In his closing remarks, Grimsby and North Lincolnshire coroner Paul Kelly said due to the age of the incident and considering how Cristal is a heavily regulated site, he felt it "inappropriate" to make any further recommendations.
