Confined spaces present serious risks that can lead to injury or death when proper precautions are not taken. Toxic atmospheres, oxygen deficiencies, and explosion hazards are common in many work environments, and an average of 20 people lose their lives each year due to confined space incidents. More than half of those fatalities involve untrained workers attempting rescue.

This Confined Space Hazards International course gives learners a clear understanding of the dangers associated with confined spaces and the steps required to protect themselves and others. The training explains how to recognize confined spaces, identify hazardous conditions, understand atmospheric risks, and follow employer procedures that support safe entry and monitoring. Learners also explore the responsibilities of entrants, attendants, and entry supervisors, as well as how to respond appropriately when hazardous atmospheres or emergency situations arise.

By the end of the course, participants will understand how to work safely in or around confined spaces, when a permit may be required, and how to prevent incidents that could cause serious harm.

A confined space may appear harmless, but hidden dangers such as toxic gases, oxygen displacement, engulfment hazards, and restricted access can make these areas extremely unsafe. Recognizing confined spaces, knowing how atmospheric conditions change, and understanding the procedures in place to protect workers is essential for preventing life-threatening incidents. This course provides the foundation needed to identify confined space hazards and apply safe work practices confidently.
