Sections 15, 16 and 17 of the Machinery Act 1950 require moving parts of prime movers, every part of transmission machinery and every dangerous part of any machinery to be securely fenced unless it is in such a position or of such construction as to be as safe to every person employed or working on the premises as it would be if securely fenced.

The technical information in this book was current at the time of printing in 1979. While the guarding principles are still valid, the information does not necessarily reflect technological changes since the booklet was first published.

This booklet should be read in conjunction with the book Guidelines for Guarding Principles and General Safety for Machinery.
