Firefighters rescued a man from a rooftop in Cleveleys after he collapsed while working on telecom transmitters this morning.
Crews were called to Dorset Avenue at around 10.25am, and used an aerial ladder platform (ALP) to help the man down approximately half an hour later.
He was handed over to waiting paramedics and taken to Blackpool Victoria Hospital, a spokesman for Lancashire Fire and Rescue Service said.
Police closed the road while the rescue operation took place, with a nearby worker telling The Gazette he was not allowed to the leave the building to see what was going on.
The man, in his 40s, fell ill while working on the roof of Cleveleys Business Centre, fire service spokesman Kevin Warwick said.
He said he 'had collapsed but was conscious and breathing, although his workmate reported that he seemed confused'.
And he added: "He was assessed by paramedics who advised that due to his low blood pressure we needed to bring him down horizontally. The man was stabilised on the roof and brought down using an ALP.
"We don't use the ladder on a daily basis but for incidents like this the ALP is worth its weight in gold.
"It made for a quick and clean rescue."
