As a subject matter expert in occupational safety and health, I can provide you with information on the minimum oxygen levels for a confined space.
In the United States, the Occupational Safety and Health Administration (OSHA) sets the standard for confined spaces. According to OSHA, the minimum oxygen level in a confined space must be 19.5%. However, it's important to note that a level of 23.5% is considered optimal for most workers. Levels below 19.5% can be dangerous and require the use of a respirator. Additionally, the atmosphere in a confined space should be tested for other contaminants that could be harmful.
