Z3591

Z359.1, commonly referred to as ANSI/ASSE Z359.1, is the American National Standard for Personal Fall Arrest Systems. It is part of the Z359 family of fall protection standards and provides the minimum requirements for personal fall arrest equipment and its use. The standard covers components such as full-body harnesses, connectors (including lanyards and deceleration devices), energy absorbers, lifelines, and anchors, and it outlines performance criteria, compatibility, labeling, and user instructions.

Key areas addressed by Z359.1 include design and performance requirements for equipment, instructions for proper use, inspection and maintenance procedures, and criteria for retiring damaged or degraded gear. It also emphasizes the need for a fall protection plan, worker training, and the proper selection of components based on the specific work environment and hazards. The standard discusses safe operation considerations, including fall clearance and deceleration distance, to help prevent injury during a fall.

The scope applies to workplaces and activities where workers are exposed to fall hazards and is widely used in construction, manufacturing, and other high-risk sectors. While OSHA regulations require fall protection where applicable, adherence to Z359.1 is commonly used as a basis for compliance, procurement, and program development. The standard is periodically revised to reflect advances in technology and evolving best practices, so users should consult the latest edition for current requirements.
