The first steps of this lesson
Step 1: Connector Fall Protection Depends on Two Heights
For ironworkers connecting beams, the rule steps up at two fall distances. Where the fall distance is greater than two stories or 30 feet, whichever is less, iron workers must be provided with and use a personal fall protection system tied off to columns, pendant lines secured at the tops of columns, catenary lines, or other secure anchorage points. At heights over 15 and up to 30 feet above a lower level, connectors must be provided with a personal fall arrest, positioning device or fall restraint system and wear the equipment needed to be able to be tied off, or be provided with other means of protection from fall hazards under subsection (m). Source: 8 CCR Section 1710(m)(1)(A) and (B).
Step 2: Whichever Is Less: Story Height Changes the Limit
The upper threshold is two stories or 30 feet, whichever is less. With 12 ft stories, two stories is 24 ft, so the tie-off requirement starts at 24 ft, not 30 ft. Only with stories of 15 ft or more does 30 ft become the limit. Shinning (vertically climbing) columns to reach a work point is allowed only where the fall distance does not exceed that same limit. Other (non-connecting) work at a work point needs personal fall protection once the fall exceeds 15 feet. Source: 8 CCR Section 1710(m)(1)(A), (m)(1)(C), and (m)(2).
The remaining 3 steps, the worked example and the quiz are in the course. This is a preview. The full lesson, with the step-by-step explanations, a worked example and a quick-check quiz, is inside the classroom.
