Danger Open Trench Keep Clear Sign – Construction Trench Hazard Safety Sign
This Danger Open Trench – Keep Clear safety sign warns workers, contractors and visitors of an open trench hazard. Open trenches present serious risks including falls, unstable ground conditions, collapsing edges and underground service exposure, making clear hazard identification essential on active worksites.
