OK, like I said, you're in the US and it goes on the OSHA 300 log and as a Recordable as well.
I don't know what kind of "board" you're referring to, but OSHA doesn't give a flip about that internal posting other than the annual one of your previous year's OSHA 300. I've been a Safety & Health professional for nearly 40 years, I've a BS in Safety, and I've done and audited it from Alaska to Dubai across multiple national legal systems.
You also need to show an investigation into the injury, you can use the OSHA 301. Best yet, here are the required BY LAW, OSHA forms.
Or you can listen to the guy in the UK.
