The Scaffold & Access Industry Association (SAIA) is the leading trade association for the scaffolding and access industry in North America. Founded in 1972 and headquartered in the United States, SAIA represents scaffold and access equipment manufacturers, distributors, erectors, and service providers across the USA, Canada, and Mexico. The association plays a central role in developing and promoting safety standards, education, and professional certification for scaffolding and access professionals throughout North America. SAIA works closely with the US Occupational Safety and Health Administration (OSHA), the American National Standards Institute (ANSI), and other regulatory bodies to develop and revise industry-specific safety codes and best practice guidelines.

SAIA administers the Scaffold Safety Training (SST) programme, providing recognised credentials for scaffold erectors, users, and managers across North America. The association offers a suite of technical publications, training materials, and industry resources covering scaffold design, erection, and inspection. SAIA’s annual convention and exposition is a key event in the North American scaffolding calendar, bringing together manufacturers, contractors, and safety professionals to share knowledge and innovations in the access industry. Through its committees and working groups, SAIA actively develops technical documents and co-ordinates industry responses to proposed changes to OSHA scaffolding regulations and ANSI/SSFI scaffold standards.
