The milestone represents the highest number of valid cardholders for the scheme since is started back in the 1960s.
David Mosley Scheme Manager said: “To reach 50,000 current card holders is a great achievement.
“The numbers may not seem huge when compared to some other industry schemes, but we know that our cardholders have had to work hard to achieve their CISRS status and that they are part of a select few industry recognised competency cards schemes.
“Well done to all involved, the card holders, their employers, the training providers and the CISRS team.”
The scheme is supported by most of the major names in the scaffolding industry.
Dave Francis, Access and Scaffolding Industry Training Organisation Chair and Internal Audit Manager for SGB said: “SGB have been huge supporters of CISRS since its inception.
“Over the years many of our employees at all levels have attended CISRS training courses and are CISRS card holders.
“We believe it is important for our operatives to hold valid CISRS cards so we are comfortable our staff are trained to the highest industry standard and promoting safety at the forefront of all we do.
“CISRS is held in great regard – not only by the scaffolding sector but construction industry as a whole, and SGB are proud to have contributed to its success.”
