This standard has been around since 1992, with the last major revision published in 2004. CSA has reconvened the Technical Committee responsible for this important standard to revise the […]

When designing safeguarding systems for machines, one of the basic building blocks is the movable guard. Movable guards can be doors, panels, gates or other physical barriers that can be opened without using tools. Every one of these guards […]
