What does SG4:15 cover?

SG4:15 provides guidance on the minimum standards for scaffolding safety, including the correct use of equipment, the minimum height requirements for guardrails and toeboards, and the selection and use of appropriate fall arrest equipment. The document also provides details on the necessary training and qualifications for scaffolding operatives and supervisors and outlines essential requirements for scaffolding inspection and maintenance.

What does TG20:13 cover?

TG20:13 sets out the technical requirements for scaffolding design and construction. The guidance includes specific details on scaffold design, structural calculations, and the use of different types of scaffold systems. The document also provides advice on selecting the right components and materials for different scaffold applications and outlines the essential requirements for scaffold inspections and record-keeping.

How do the documents work together?

SG4:15 and TG20:13 work hand in hand to ensure scaffolding safety from design through to erection, maintenance, and dismantling. SG4:15 provides a set of minimum standards for scaffolding safety that scaffolders and site managers must follow, while TG20:13 provides the technical guidance necessary to ensure that scaffolds are designed and built to the required safety standards.
