How long does a confined space certification last?

Industry leaders recommend that you refresh Confined Space Training every one or two years.
How often do you need to do confined space training?
Certification for confined space training doesn't have an expiration day. However, re-training or refresher training should be provided every two years depending on how often work related to confined spaces is being completed.
