Confined Spaces: Identifying Hazards
Learning objectives
- Identify common atmospheric hazards (oxygen deficiency, flammable gases, toxic gases) and non-atmospheric hazards in confined spaces.
- Explain the standard order and methods for atmospheric testing (oxygen r flammables r toxic r others).
- Differentiate between continuous and periodic monitoring strategies and interpret testing results vs. permissible limits.
- Determine the hierarchy of controls (eliminate, substitute, engineering controls, administrative, PPE) to confined space hazard mitigation.
- Develop or refine hazard communication strategies (signage, labeling, pre-entry alerts) for confined spaces.
Course overview
Confined space hazards often remain invisible until they create serious harm. This course helps you identify atmospheric hazards such as oxygen deficiency, flammable gases, and toxic contaminants, along with physical and mechanical dangers. It also outlines proper atmospheric testing order, monitoring strategies, and the hierarchy of controls that reduce risk before entry begins.
