The 1,800-pound impact force limit applies when a deceleration unit is used.

• A. True
• B. False
• C. Not Specified
• D. Only With Certain Equipment

Answer: (A)

When a fall is arrested, the forces on the body matter a lot. A deceleration device slows the stop, increasing the distance over which the body comes to a halt. That extended stopping distance lowers the peak force transmitted to the climber, so safety standards set a maximum arresting force of 1,800 pounds for systems that include a deceleration device. Because this limit specifically applies once a deceleration unit is part of the fall-arrest setup, the statement is true. The other options don’t fit because the rule is defined in relation to the use of a deceleration device, not as a generic or unspecified requirement or restricted to only some equipment.
