The latest accident survey for 2013/14 shows that over the last 11 years the NSCC fatality rate has fallen by 81% and the specified/major injury rate by 57%.
Both the NSCC fatality rate and over 7-day injury rate for 2013/14 were lower than the industry as a whole.
NSCC recorded one fatality at a rate of 0.7 per 100,000 workers compared to 42 fatalities across the industry at a rate of 2.0 per 100,000 workers.
The over 7-day injury rate was 225.3 per 100,000 workers compared to 260.1 per 100,000 workers for the industry.
The NSCC major injury rate was the second lowest in the 11-year history of the survey at 155.7 per 100,000 workers.
Almost two thirds of all accidents were the result of slips and trips, handling and lifting, or falls from height, consistent with the rest of construction.
The survey commands a high respsonse level with over 2,400 specialist contractors employing almost 135,000 operatives taking part.
NSCC Chief Executive Suzannah Nichol MBE said: “In a year which saw the first increases in activity in the specialist sector following the recession, it is encouraging that NSCC specialist contractors are still leading the way when it comes to on-site safety.”
