That section is for training in the use of "fall protection systems". If you read the section on fall protection system you will see that a ladder does not fit the definition.Training is a separate section: https://www.osha.gov/laws-regs/regulations/standardnumber/1910/1910.30
I agree, though I'd suggest starting with a worker's comp lawyer to ensure that there isn't some recourse there. With worker's comp there is no need to prove negligence.Whatever happened, the injuries suffered by Tabatha86’s boyfriend are severe enough that a personal injury lawyer should be consulted.
The employer might not be. But as I don't know that state's law, I can't eliminate the possibility that the worker's comp law might still provide a remedy for an injured worker against the uncovered employer without the need to prove negligence. That kind of remedy would provide further incentive for employers to ensure they are covered by worker's comp insurance.I have no problems with that, even though I suspect the employer isn’t covered.
