Title 8 CCR §1670 lists the acceptable forms of personal fall protection in construction. Which of the following is NOT recognized as a complete fall-protection system under that section?

Explanation

Section 1670(b) has barred body belts from personal fall arrest systems since 1 January 1998, because the arresting force concentrates on the abdomen and a suspended worker hangs jack-knifed; the belt survives only in a positioning device system under section 1670(c), where no free fall may exceed 2 feet, and in fall restraint under section 1670(d). The other three are accepted methods. A safety net under section 1671 goes as close as practicable beneath the work surface and never more than 30 feet below it. A personal fall arrest system needs an anchorage supporting at least 5,000 pounds per employee attached, connectors, and a full-body harness, with the arresting force on the employee limited to 1,800 pounds. And a section 1620 guardrail has a top rail at 42 to 45 inches with a mid-rail halfway down.
