The first thing you need to do is report the injury to human resources.  They are required to keep an OSHA log of any injuries in the workplace.  You are required to report.  If you fail to report the injury, then you could potentially waive some of your worker's comp rights.Your second option is to decide if you still want to be with the company.  You are not required to stay with them if you don't want to -- namely because it appears they have soe questionable safety practices.  If you do want to stay, attend the orientation so that you know how to avoid the next potential injury.
