In California construction work, fall protection is generally required when a worker is exposed to a fall of what height or more?

b.4 feet

Giải thích
Cal/OSHA construction standards generally require fall protection when a worker is exposed to a fall of 7½ feet or more (stricter than the federal 6-foot general rule in some situations). The 10- and 20-foot answers would leave workers exposed, and 4 feet is the general-industry-style threshold, not the construction trigger here.
