Overview
Construction of underground tunnels, shafts, chambers, and passageways are essential yet dangerous activities. Underground construction workers face many hazards, such as reduced natural ventilation and light, difficult access/egress, exposure to air contaminants, fire, flooding, and explosion. As such, OSHA enforces regulations for underground construction in accordance with the Code of Federal Regulations (CFR) Title 29, Subpart S. These regulations originate from 1971 and have been revised over the years to enhance worker safety.
This course is intended for engineers in the construction industry who 1) oversee construction work that occurs substantially below ground, and 2) desire a general understanding of OSHA’s guidance on underground construction safety. The course material is based on OSHA publication 3115 Underground Construction (Tunneling).
