Alan Catterall , 54 , was burned to death at work when the door slammed shut on the industrial oven he was cleaning . A business has been fined £200,000 over the death of a worker who became trapped inside an industrial oven which was then accidentally turned on by his future son-in-law . Alan Catterall , 54 , died while carrying out cleaning work at Runcorn-based Kayak company , Pyranha Mouldings in December 2010 . The father-of-three from Halewood , Liverpool , had gone inside to clean molten plastic escaping from a mould while the oven was switched off after a fault developed . Liverpool Crown Court heard the oven had developed a fault with a guide rail bearing and had been shut down for maintenance so the bearing could be fixed . But once the maintenance work had been completed the oven was switched back on by colleague Mark Francis , who was engaged to Mr Catterall 's daughter , and put into warm-up mode . A few minutes later smoke was seen coming from the oven and when operators opened the door to find the source they discovered Mr Catterall 's body . He was pronounced dead at the scene . The court heard Mr Catterall suffered severe burns and died of shock after becoming trapped in the large bespoke oven , which was designed to accommodate the moulds for two kayaks . He was a senior supervisor at the company , which manufactures kayaks and canoes , and had worked there for 12 years . Pyranha Mouldings was also found guilty of two charges under the Health and Safety at Work Act 1974 . Peter Mackereth , 60 , managing director of the company , was convicted of two charges under Section 37 of the Health and Safety at Work Act . Sentencing was adjourned until today when the trial judge , sitting at the Royal Courts of Justice in London , imposed the £200,000 fine . Mackereth was given a suspended sentence and a fine of £25,000 . The judge imposed a total prison sentence of nine months , suspended for two years . Mr Justice MacDuff awarded costs against the two defendants jointly in the total sum of £90,000 . The judge said there were ' a number of serious failings in the design of this and other moulding ovens ' - the design and commissioning of which had been done in-house . Mr Justice MacDuff said Mr Catterall was 'by all accounts the most lovely of men ' , devoted to his family 'and loved by all ' . 'He was a committed worker and had given 100 % and more to his employers , ' said the judge . His wife Pearl had 'behaved with dignity throughout ' . He added : 'Her loss , I know , is nearly unbearable and she knows that I can do nothing to bring back her husband . ' Mr Catterall , 54 , died while carrying out cleaning work at Runcorn-based Kayak company , Pyranha Mouldings in December 2010 . Liverpool Crown Court heard the oven had developed a fault with a guide rail bearing and had been shut down for maintenance so the bearing could be fixed . The company was today fined £20,000 . When announcing the fine to be imposed on the company , the judge said that what happened was 'in the true sense ' an accident : 'It was an avoidable accident but nevertheless an accident ; an accident courted by no-one . ' Referring to Mr Catterall 's family , the judge said : 'At least they are able to understand that their loss was not caused by a deliberate unlawful act ; rather it was a result of oversight , negligence , sins of omission and not of commission , but sins nevertheless . ' Sentencing Mackereth , he said : 'You do not need me to tell you how far short of your duty you fell . It was repeatedly brought home to you at the trial . 'You will have to live with the consequences of your actions for the rest of your life . The company may only act through its directors and senior officers . 'Whereas others were also involved , you had to accept that you took the lead in designing and commissioning these ovens . The company 's failure was also your failure - although the full responsibility does not fall on your shoulders . Rightly you were not charged with gross negligence manslaughter . ' The judge said he fully accepted that Mackereth and Mr Catterall were friends 'and that you were also devastated by the loss ' . He told Mackereth : ' I have given the matter careful thought and have reached the conclusion that I should mark the gravity of your offending by imposing a prison sentence , albeit that there are circumstances which enable me to suspend that sentence .
