What is the purpose of a Personal Fall Arrest System?

• A. To Arrest a Fall if It Occurs
• B. To Prevent All Movement from Height
• C. To Provide a Platform at Height
• D. To Secure the Workers Tools

Answer: (A)

The purpose of a Personal Fall Arrest System is to stop a fall after it has begun. It uses a properly fitted harness, connectors, and an anchor with a deceleration device or energy absorber to slow the fall and limit the distance you drop and the force on your body, reducing injury risk. It is not meant to prevent all movement from height—that would be fall restraint or other systems—and it does not provide a platform or secure tools. After the fall is arrested, a prompt rescue is still required because the system is designed to protect you during the fall, not to serve as a standing work surface.
