Bjarney:
That is an excellent question!
The mfg may give an answer.....
It probably will be "we do not intend that it be used for support of personel"
Thinking about this, in the lawyer crazy, suit filled world that we are a part of...
implying that an item "could" be used for a purpose, can land anyone in court. I'm not bashing lawyers, but.....
IF it could possibly be approved OSHE probably would require a guard rail, toe kicks, and a tie-down beam!!!
Good Luck
