If you run a construction site in Tennessee, signage is not just a “nice to have.” When workers, visitors, drivers, or the public may be exposed to hazards, contractors need clear accident-prevention signs, tags, and traffic-control devices that match the site conditions. TOSHA enforces Tennessee’s OSHA-approved state plan and has adopted the federal OSHA construction standards, including 29 CFR 1926 Subpart G for signs, signals, and barricades.
