These shocking pictures show a window cleaner balancing on a top floor ledge — without ANY safety equipment.
The man appears to use only his left hand to cling on to the outside of a third floor flat while wiping the windows with his other hand.
Witnesses said he left the property through the window before carrying out the dangerous task, branding him “fearless” but “stupid”.
Barry McLauchlan, 22, who was working on the opposite side of Caird Drive, Glasgow, recorded the terrifying moment on Monday morning.
The labourer, from Hamilton, South Lanarkshire, said: “I was just working away and looked across the street. I noticed this window cleaner.
“I thought nothing of it, but the more I stared I noticed he wasn’t wearing any safety equipment. There was no harness or safety aids.
“I was shocked. I was fearing more for his life than he was.
“I saw him climb out of the window. He closed it behind him and washed the window as if it was a ground floor and nothing had happened.
“Except from his hand holding on to the window, there was nothing keeping him there.”
Barry and his colleagues believe he must be self-employed or just a member of the public.
He said: “I work in the construction industry and know how important it is to stick to health and safety.
“He’s a braver guy than I am. But there is fearless and then there is stupid.
“You’ve got to think about health and safety. My thought is that this guy is self-employed because any company’s insurance would not have paid for that.”
The Health and Safety Executive (HSE), which regulates the workplace, said it could not comment as the man may have just been a member of the public.
But a spokesman added: “Falls from height are one of the biggest causes of workplace fatalities and major injuries, and we would hope anyone working at height took necessary precautions to prevent an incident.”
