When dropping debris without chutes, barricades are required to be how high and how far back from the projected edge of the opening?

• A. 42 inches high and 6 feet back
• B. 36 inches high and 4 feet back
• C. 48 inches high and 8 feet back
• D. 30 inches high and 3 feet back

Answer: (A)

The requirement for barricades when dropping debris without chutes specifies that the barricades must be 42 inches high and set back 6 feet from the projected edge of the opening. This height and distance are designed to provide adequate protection for individuals in the vicinity, as the barricade must be sufficiently tall to prevent debris from going over the top and far enough back to ensure that people are out of the potential falling debris zone. This practice is crucial in enhancing safety on construction sites and ensuring compliance with safety regulations, thereby mitigating the risk of injuries caused by falling objects.
