some one at OSHA just had a heart attack

Good reason to have this reach viral status......

Another proof of Mike Rowe's "Safety Third" concept. NO program form of administrative oversight makes this safe, or more correct term 'safer'. The young lady is obviously comfortable with the routine but not complacent. This is real safety; first person.
That does not mean I approve of the process, but realize supporting herself is a powerful motivation.
