A Wrexham-based dairy firm has been fined £200,000 and ordered to pay costs of £4,267 after a worker was covered in hot caustic and steam resulting in serious injuries. An investigation by the Health and Safety Executive (HSE) found the company had failed to ensure the safe isolation of plant and pipework before work commenced. The company had relied on informal risk control systems and arrangements which were no longer sufficient for a business of its size.
