Disclaimer:
Things might have changed here recently that I'm not aware of...
But...The basic rule-of-thumb for manufactures of temporary, non-suspended work platforms to follow, is to build and test them where they'll meet or exceed an engineering-factor of at least 1.25-1.50 times the load limit.
So...
Has the manufacturer of this Werner platform proven to be a responsible member of the World's manufacturing community...
that has shown due diligence in following engineering standards for temporary work platforms?
Not that I will ever, ever endorse doing so:
I have, and use, two of these Werner platforms quite
often---and not just when detailing---and I do exceed (by a rather sizable plus-amount) the stated load limit of 225 lbs.
Note:
Got mine on sale for ~$17, if I remember correctly.
In conclusion:
Choose wisely, the equipment to use, when considering working above ground level.
Higher rated temporary work platforms are readily available...For a few more dollars.
