Underground Construction Safety
Course Highlights

This online engineering PDH course summarizes OSHA's regulations related to underground construction.


The construction of underground tunnels, shafts, chambers, and passageways are essential yet dangerous activities. Working under reduced light conditions, difficult or limited access and egress, with the potential for exposure to air contaminants and the hazards of fire and explosion, underground construction workers face many dangers. OSHA recognizes that working in underground environments presents serious hazards to all workers involved. Therefore OSHA developed the underground construction standard to protect the safety and health of underground construction workers.


This 3 PDH online course is applicable to employers/business owners, engineers, managers, construction workers and all other personnel involved with underground construction projects.
