Confined Space: Marine Confined Space

This refresher training prepares anyone working in or around confined spaces to recognize, evaluate, and control the environment of a confined space. Presented with graphics, text, and complete narration, the training defines a confined space and explains how to recognize and understand atmospheric and physical hazards within confined spaces.

The user learns about qualitative and quantitative methods of measurements used in evaluate confined spaces, and how that relates to safe entry. Finally, learner are taught the precautions necessary to maintain safe entry, work, and exit conditions within a Maritime confined space.
