John Houghton, 56 was blinded when a pipe burst, spraying caustic cleaning fluid into his eyes.
The incident happened when a colleague accidentally stood on the pipe and a defective clamp gave way, causing it to explode in Houghtons face.
He was treated in hospital but was unable to see for three days, and needed four weeks off work to recover.
Scars from burns
He regained his full eyesight but was left with scars from burns to his left shoulder and upper leg.
