605 Confined Space Safety
Skip to main content

What is Confined Space "Entry"?

When any part of a person's body crosses the plane of an opening into a space, it is considered a confined space entry. Each employer should ask these two questions at the onset of each project:

  1. Is confined space entry always necessary for this task?
  2. Is it possible to complete the task from the outside?
Working in a confined space.

If possible, avoid entering a confined space. Every consideration should be given to completing the task from the outside.

Using Alternative Entry Procedures

Under certain conditions, you may use alternate procedures for worker entry into a permit space. For example, suppose you can demonstrate with monitoring and inspection data that the only hazard is an actual or potentially hazardous atmosphere that can be made safe for entry using continuous forced air ventilation. In this case, you may be exempt from some entry requirements, such as permits and attendants.

However, even in these circumstances, you must test the space's internal atmosphere for oxygen content, flammable gases and vapors, and the potential for toxic air contaminants before any employee enters it. You must also provide continuous ventilation and verify that the required measurements are performed before entry.
