Confined Spaces

Online Training Certification Course

29 CFR 1910.146

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

Numerous health and safety hazards exist within confined spaces, and anyone who might work in these dangerous environments must receive confined space training.

Working in confined spaces is dangerous, and risks include suffocation, engulfment, and inability to be rescued. Workers must understand the risks and take all proper precautions prior to entering the space, while working in the space, and when leaving the space.

Topics in this online certification course presents a general overview of confined space regulations as they relate to entrants, attendants, and supervisors. It covers the proper methods and rules that must be followed before, during, and after confined space entry. Confined space training also addresses the role of initial and atmospheric testing and ongoing monitoring; the entry permit and the permit space safety program; examples of accidents and fatalities in confined spaces; and duties and responsibilities of key confined space personnel.

This course is for:
This confined spaces training course is designed for anyone who works in general industry and may enter confined spaces with potential hazards. OSHA uses the term "general industry" to refer to all industries not included in agriculture, construction, or maritime activities.

Confined space supervisors, entrants, and attendants are required to receive OSHA confined space training. Requirements for safety training apply to any worksite considered "confined," including sumps, pits, pipes, tunnels, tanks, and silos. This safety training may help prevent serious injury in the workplace and save lives.

Case Study: On October 2nd, 2007, five people were killed and three others injured when a fire erupted 1,000 feet underground in a tunnel at a hydroelectric power plant in Georgetown, Colorado. The tunnel, which was several thousand feet long and connected two reservoirs with electricity-generating turbines, trapped the fatally injured workers deep underground during an operation to coat the inside of the tunnel with epoxy using highly flammable solvents.
