I would like to have one myself being welding for 40 plus years and never have seen one. I sent the e-mail to my boss but it might not do any good. It would make my life a little better on me.
Any company concerned with "back injures" as a recordable incident would use one as standard operation in their business.
This may assist a company in a small reduction of worker compensation insurance rate, especially if the company has had recordable back injuries due to lifting.
Have a conversation with the owner/owners of the company.
