Underground Construction Training

Online Training Certification Course

29 CFR 1926 Subpart S

From the highest rated and most trusted online training company - since 2008.

The dangers of construction work are well documented. To put them in perspective, out of 4,779 worker fatalities in United States private industry in calendar year 2018, 21.1% were in construction. In other words, one in five worker deaths in 2018 were in construction.

Safety training is the first step toward adopting safety behaviors. In tandem, understanding regulations and adopting a mindset of safety are proven ways of preventing injury, illness, and death.

This course is for:
This OSHA Underground Construction training is designed for anyone employees involved in underground construction must be trained to recognize and respond to hazards associated with this type of work. Training should be tailored to the specific requirements of the jobsite and include any unique issues or requirements.

This online certification course meets the requirements set forth by OSHA for the Underground Construction Standard.

Case Study: In February 2010, construction crews from a Minneapolis, Minnesota, utility company were installing a telephone cable in a residential neighborhood using a common construction technique, horizontal directional drilling. When they apparently struck a gas main in the street, a natural gas explosion occurred that destroyed one home and damaged another.

Key Takeaway: While no one was injured, the blast highlights the risks of drilling underground. It was not clear if the telephone cable installers actually dug down and saw the gas line, which they were supposed to bypass with the drill. Remember: If you see something that seems unsafe, call it to the attention of your coworkers and foremen. Safety is the job of every person at the worksite, regardless of seniority or job title.
