What OSHA regulations apply to construction?

OSHA construction standards in 29 CFR 1926 create comprehensive safety requirements with violations establishing negligence per se. Fall protection requires guardrails, safety nets, or personal fall arrest above six feet. Scaffolding standards specify design, assembly, inspection, and use requirements preventing collapses. Excavation rules mandate protective systems for trenches over five feet deep. Electrical safety includes lockout/tagout, ground fault protection, and qualified person requirements. Personal protective equipment obligations cover hard hats, safety glasses, and hearing protection. Hazard communication ensures workers understand chemical dangers through training and labeling. Crane regulations require qualified operators, inspection protocols, and load calculations. Ladder standards specify design, inspection, and proper use preventing falls. Steel erection rules address unique hazards of structural steel construction. Confined space procedures protect workers from atmospheric and engulfment hazards. Training requirements ensure workers understand job hazards and protective measures. Record-keeping obligations document injuries, illnesses, and safety programs. Multi-employer worksites create overlapping duties for different employers. State plan variations may impose stricter requirements in 27 states. Understanding OSHA requirements helps prove violations causing injuries while establishing employer negligence.
