What defines a confined space in accordance with Coast Guard policy?

A confined space, as defined by Coast Guard policy, is characterized by its unfitness for continuous human habitation. This means that the environment within the space may not support human life for extended periods due to factors such as inadequate oxygen levels, presence of toxic gases, or other hazardous conditions. Confined spaces can include tanks, vessels, and other similar environments where the air quality cannot be guaranteed and where egress in case of an emergency might be difficult.

The definition emphasizes the potential risks associated with working in such spaces, which may require special training or precautions to ensure the safety of individuals entering or working within them. This understanding is crucial for pollution responders and other professionals who may encounter these spaces during their operations, as it underscores the necessity of evaluating and managing hazards effectively to protect human health and safety.
