The 52-year-old, who was sacked as manager of Nottingham Forest on Sunday (February 1), worries he came into contact with the potentially-deadly material before becoming a professional footballer.
Mr Pearce, who famously missed a spot kick in the 1990 World Cup semi-final shoot-out, only to redeem himself in Euro '96, was a trainee apprentice for the council in the early 1980s.
The Nottingham Forest legend, who has also managed Manchester City, spent four years re-wiring homes, schools and factories before turning pro at 21.
But he was never told about asbestos, then common in buildings, which can cause incurable mesothelioma.
He said: “The chances I worked with asbestos while an apprentice are high.
“We were briefed on safety hats and boots but I don’t recall asbestos mentioned once. It’s chilling to think of the risks we were exposed to.
“Sending workers into a building with asbestos without warning of the dangers was asking for trouble.”
He is now backing the Health and Safety Executive campaign Every Job Beware Asbestos.
